What is School Psychology?

Published on by Andrew Marshall1 Comment

Introduction

School psychology is a field that applies principles from educational psychology, developmental psychology, clinical psychology, community psychology, and behaviour analysis to meet the learning and behavioural health needs of children and adolescents.

It is an area of applied psychology practiced by a school psychologist. They often collaborate with educators, families, school leaders, community members, and other professionals to create safe and supportive school environments.

School psychologists primarily work with students who have learning disabilities, behavioural difficulties, mental disorders, and other health issues. They carry out psychological testing, psychoeducational assessment, intervention, prevention, counselling, and consultation in the ethical, legal, and administrative codes of their profession.

Background

School psychology dates back to the beginning of American psychology in the late 19th and early 20th centuries. The field is tied to both functional and clinical psychology. School psychology actually came out of functional psychology. School psychologists were interested in childhood behaviours, learning processes, and dysfunction with life or in the brain itself. They wanted to understand the causes of the behaviours and their effects on learning. In addition to its origins in functional psychology, school psychology is also the earliest example of clinical psychology, beginning around 1890. While both clinical and school psychologists wanted to help improve the lives of children, they approached it in different ways. School psychologists were concerned with school learning and childhood behavioural problems, which largely contrasts the mental health focus of clinical psychologists.

Another significant event in the foundation of school psychology as it is today was the Thayer Conference. The Thayer Conference was first held in August 1954 in West Point, New York in Hotel Thayer. The 9 day-long conference was conducted by the American Psychological Association (APA). The purpose of the conference was to develop a position on the roles, functions, and necessary training and credentialing of a school psychologist. At the conference, forty-eight participants that represented practitioners and trainers of school psychologists discussed the roles and functions of a school psychologist and the most appropriate way to train them.

At the time of the Thayer Conference, school psychology was still a very young profession with only about 1,000 school psychology practitioners. One of the goals of the Thayer Conference was to define school psychologists. The agreed upon definition stated that school psychologists were psychologists who specialise in education and have specific knowledge of assessment and learning of all children. School psychologists use this knowledge to assist school personnel in enriching the lives of all children. This knowledge is also used to help identify and work with children with exceptional needs. It was discussed that a school psychologist must be able to assess and develop plans for children considered to be at risk. A school psychologist is also expected to better the lives of all children in the school; therefore, it was determined that school psychologists should be advisors in the planning and implementation of school curriculum. Participants at the conference felt that since school psychology is a specialty, individuals in the field should have a completed a two-year graduate training program or a four-year doctoral programme. Participants felt that states should be encouraged to establish certification standards to ensure proper training. It was also decided that a practicum experience be required to help facilitate experiential knowledge within the field.

The Thayer Conference is one of the most significant events in the history of school psychology because it was there that the field was initially shaped into what it is today. Before the Thayer Conference defined school psychology, practitioners used seventy-five different professional titles. By providing one title and a definition, the conference helped to get school psychologists recognised nationally. Since a consensus was reached regarding the standards of training and major functions of a school psychologist, the public can now be assured that all school psychologists are receiving adequate information and training to become a practitioner. It is essential that school psychologists meet the same qualifications and receive appropriate training nationwide. These essential standards were first addressed at the Thayer Conference. At the Thayer Conference some participants felt that in order to hold the title of a school psychologist an individual must have earned a doctoral degree.

The issues of titles, labels, and degree levels are still debated among psychologists today. However, APA and NASP reached a resolution on this issue in 2010.

Social Reform in the Early 1900s

The late 19th century marked the era of social reforms directed at children. It was due to these social reforms that the need for school psychologists emerged. These social reforms included compulsory schooling, juvenile courts, child labour laws as well as a growth of institutions serving children. Society was starting to “change the ‘meaning of children’ from an economic source of labour to a psychological source of love and affection”. Historian Thomas Fagan argues that the preeminent force behind the need for school psychology was compulsory schooling laws. Prior to the compulsory schooling law, only 20% of school aged children completed elementary school and only 8% completed high school. Due to the compulsory schooling laws, there was an influx of students with mental and physical defects who were required by law to be in school. There needed to be an alternative method of teaching for these different children. Between 1910 and 1914, schools in both rural and urban areas created small special education classrooms for these children. From the emergence of special education classrooms came the need for “experts” to help assist in the process of child selection for special education. Thus, school psychology was founded.

Important Contributors to the Founding

Lightner Witmer

Lightner Witmer has been acknowledged as the founder of school psychology. Witmer was a student of both Wilhelm Wundt and James Mckeen Cattell. While Wundt believed that psychology should deal with the average or typical performance, Cattell’s teachings emphasized individual differences. Witmer followed Cattell’s teachings and focused on learning about each individual child’s needs. Witmer opened the first psychological and child guidance clinic in 1896 at the University of Pennsylvania. Witmer’s goal was to prepare psychologists to help educators solve children’s learning problems, specifically those with individual differences. Witmer became an advocate for these special children. He was not focused on their deficits per se, but rather helping them overcome them, by looking at the individual’s positive progress rather than all they still could not achieve. Witmer stated that his clinic helped “to discover mental and moral defects and to treat the child in such a way that these defects may be overcome or rendered harmless through the development of other mental and moral traits”. He strongly believed that active clinical interventions could help to improve the lives of the individual children.

Since Witmer saw much success through his clinic, he saw the need for more experts to help these individuals. Witmer argued for special training for the experts working with exceptional children in special educational classrooms. He called for a “new profession which will be exercised more particularly in connection with educational problems, but for which the training of the psychologist will be a prerequisite”.

As Witmer believed in the appropriate training of these school psychologists, he also stressed the importance of appropriate and accurate testing of these special children. The IQ testing movement was sweeping through the world of education after its creation in 1905. However, the IQ test negatively influenced special education. The IQ test creators, Lewis Terman and Henry Goddard, held a nativist view of intelligence, believing that intelligence was inherited and difficult if not impossible to modify in any meaningful way through education.] These notions were often used as a basis for excluding children with disabilities from the public schools. Witmer argued against the standard pencil and paper IQ and Binet type tests in order to help select children for special education. Witmer’s child selection process included observations and having children perform certain mental tasks.

Granville Stanley Hall

Another important figure to the origin of school psychology was Granville Stanley Hall. Rather than looking at the individual child as Witmer did, Hall focused more on the administrators, teachers and parents of exceptional children He felt that psychology could make a contribution to the administrator system level of the application of school psychology. Hall created the child study movement, which helped to invent the concept of the “normal” child. Through Hall’s child study, he helped to work out the mappings of child development and focused on the nature and nurture debate of an individual’s deficit. Hall’s main focus of the movement was still the exceptional child despite the fact that he worked with atypical children.

Arnold Gesell

Bridging the gap between the child study movement, clinical psychology and special education, Arnold Gesell, was the first person in the United States to officially hold the title of school psychologist, Arnold Gesell. He successfully combined psychology and education by evaluating children and making recommendations for special teaching. Arnold Gesell paved the way for future school psychologists.

Gertrude Hildreth

Gertrude Hildreth was a psychologist with the Lincoln School at Teacher’s College, Columbia then at Brooklyn College in New York. She authored many books including the first book pertaining to school psychology titled, “Psychological Service for School Problems” written in 1930. The book discussed applying the science of psychology to address the perceived problems in schools. The main focus of the book was on applied educational psychology to improve learning outcomes. Hildreth listed 11 problems that can be solved by applying psychological techniques, including: instructional problems in the classroom, assessment of achievement, interpretation of test results, instructional groupings of students for optimal outcomes, vocational guidance, curriculum development, and investigations of exceptional pupils. Hildreth emphasized the importance of collaboration with parents and teachers. She is also known for her development of the Metropolitan Readiness Tests and for her contribution to the Metropolitan Achievement test. In 1933 and 1939 Hildreth published a bibliography of Mental Tests and Rating Scales encompassing a 50-year time period and over 4,000 titles. She wrote approximately 200 articles and bulletins and had an international reputation for her work in education.

Issues Related to School Psychology

Intervention

One of the primary roles and responsibilities of school psychologists working in schools is to ensure the interventions they utilise effectively address students’ behaviour problems. Issues arise when school psychologists do not select interventions with sufficient research-based evidence in being effective for the individual with whom they are working. School psychologists, as researchers and practitioners, can make important contributions to the development and implementation of scientifically based intervention and prevention programmes to address learning and behavioural needs of students (National Association of School Psychologists (NASP).

There is a concern with implementing academic and behavioural interventions prior to the determination for special education services, and it has also been proposed that MTSS (Multi-Tiered Systems of Support) may address these concerns. The National Association of School Psychologists (NASP) recognises the need for evidence-based prevention and intervention practices to address student learning, social emotional development, behavioural performance, instructional methodology, school practices, classroom management, and other areas salient to school-based services and improving student outcomes (National Association of School Psychologists (NASP). Intervention and prevention research needs to address a range of questions related not only to efficacy and effectiveness, but also to:

  • Feasibility given resources (e.g. time, money, staffing);
  • Acceptability (e.g. teacher, student, and community attitudes toward intervention strategies);
  • Social validity (the relevance of targeted outcomes to everyday life of students);
  • Integrity or fidelity (the extent to which individuals responsible for implementing an intervention can do so as intended by its designers); and
  • Sustainability (extent to which school staff can maintain the intervention over time, without support from external agents).

A specific example of an intervention that has recently become popular among school psychologists is the School-wide Positive Behavioural Interventions and Supports (PBIS). Authorised under IDEA, the PBIS offers a “preventative, positive, and systemic framework or approach to affect educational and behavioural change” and can be used in the support of Tiers 1-3 in the education system. Research from single-case design studies and group studies demonstrates that the intervention can result in a reduction of major disciplinary infractions and aggressive behaviour, improvement in academic achievement, an increase in prosocial behaviour, a reduction in bullying behaviour reported by teachers, and much more. Through consistent and strong implementation fidelity, PBIS can provide school psychologists opportunities to assist the administration, teaching staff, and students in broad and specific ways.

Prevention

A way in which school psychologists can help students is by creating primary prevention programmes. Information about prevention should also be connected to current events in the community.

Issues with Assessment Process

Empirical evidence has not confirmed biases in referral, assessment, or identification; however, inferences have been made that the special education process may be oversimplified. The National Research Council has called attention to the questionable reliability of educational decision making in special education as there can be vast numbers of false positives and/or false negatives. Misidentified students in special education is problematic and can contribute to long term negative outcomes.

During the identification process, school psychologists must consider ecological factors and environmental context such as socioeconomic status. Socioeconomic status may limit funding and materials, impact curriculum quality, increase teacher-to-student ratios, and perpetuate a negative school climate.

Technological Issues

With the ever growing use of technology, school psychologists are faced with several issues, both ethical and within the populations they try to serve. As it is so easy to share and communicate over technology, concerns are raised as to just how easy it is for outsiders to get access to the private information that school psychologists deal with everyday. Thus exchanging and storing information digitally may come under scrutiny if precautions such as password protecting documents and specifically limiting access within school systems to personal files.

Then there is the issue of how students communicate using this technology. There are both concerns on how to address these virtual communications and on how appropriate it is to access them. Concerns on where the line can be drawn on where intervention methods end and invasion of privacy begin are raised by students, parents, administrators, and faculty. Addressing these behaviours becomes even more complicated when considering the current methods of treatment for problematic behaviours, and implementation of these strategies can become complex, if not impossible, within the use of technology.

To incorporate topics in a school, utilise lesson plans for students and staff because the teachers need to ensure the content is connected to other meaningful topics covered in the class/school.

Racial Disproportionality in Special Education

Disproportionality refers to a group’s under or overrepresentation in comparison to other groups within a certain context. In the field of school psychology, disproportionality of minority students in special education is a concern. Special Education Disproportionality has been defined as the relationship between one’s membership to a specific group and the probability of being placed in a specific disability category. Systemic prejudice is believed by some to be one of the root causes of the mischaracterisation of minority children as being disabled or problematic.

“Research on disproportionality in the U.S. context has posited two overlapping types of rationales: those who believed disproportionate representation is linked to poverty and health outcomes versus those who believed in the systemwide racist practices that contributed to over-representation of minority students.”

The United States Congress recently received an annual report on the implementation of IDEA which stated that proportionally Native Americans (14.09%) and African Americans (12.61%) were the two most highly represented racial groups within the realm of special education. In particular, African American males have been overidentified as having emotional disturbances and intellectual disabilities. They account for 21% of the special education population with emotional disturbances and 12% with learning disabilities. American Indian and Alaska Native students are also overrepresented in special education. They are shown to be 1.53 times more likely to receive services for various learning disabilities and 2.89 more likely to obtain services targeting developmental delays than all other Non-Native American student groups combined.] Overall, Hispanic students are often overidentified for special education in general; however, it is common for them to be under-identified for Autism Spectrum Disorder and speech and language impairments in comparison to White students.

Minority populations often have an increased susceptibility to economic, social and cultural disadvantages that can affect academic achievement. According to the US Department of Education, “Black children were three times as likely to live in poor families as white children in 2015. 12 percent of white and Asian children lived in poor families, compared with 36 percent of black children, 30 percent of Hispanic children, 33 percent of American Indian children, and 19 percent of others.” There may be other alternative explanations for behaviour and academic performance as well. For example, Black children are twice as likely as Whites to experience heightened levels of lead in the blood due to prolonged lead exposure. Lead poisoning can be known to affect a child’s behaviour by increasing their levels of irritability, hyperactivity, and inattentiveness even in less severe cases.

Cultural Biases

Some school psychologists realise the need to understand and accept their own cultural beliefs and values in order to understand the impact it may have when delivering services to clients and families. For example, these school psychologists ensure that students who are minorities, including African Americans, Hispanics, Asians, and Native Americans are being equally represented at the system level, in the classroom, and receiving a fair education.

For staff, it is important to look at one’s own culture while seeing the value in diversity. It is also vital to learn how to adapt to diversity and integrate a comprehensive way to understand cultural knowledge. Staff members should keep the terms race, privilege, implicit bias, micro aggression, and cultural relevance in mind when thinking about social justice.

Services

Behaviour Interventions

School psychologists are involved in the implementation of academic, behavioural, and social/emotional interventions within a school across a continuum of supports. These systems and policies should convey clear behaviour expectations and promote consistency among educators. Continuous reinforcement of positive behaviours can yield extremely positive results. Schoolwide positive behaviour supports A systematic approach that proactively promotes constructive behaviours in a school can yield positive outcomes. These programs are designed to improve and support students’ social, behavioural, and learning outcomes by promoting a positive school climate and providing targeted training to students and educators within a school. Data should be collected consistently to assess implementation effectiveness, screen and monitor student behaviour, and develop or modify action plans.

Academic Interventions

Academic interventions can be conceptualised as a set of procedures and strategies designed to improve student performance with the intent of closing the gap between how a student is currently performing and the expectations of how they should be performing. Short term and long term interventions used within a problem-solving model must be evidence-based. This means the intervention strategies must have been evaluated by research that utilised rigorous data analysis and peer review procedures to determine the effectiveness. Implementing evidence-based interventions for behaviour and academic concerns requires significant training, skill development, and supervised practice. Linking assessment and intervention is critical for determining that the correct intervention has been chosen. School psychologists have been specifically trained to ensure that interventions are implemented with integrity to maximise positive outcomes for children in a school setting.

Systems-Level Services

Leaders in the field of school psychology recognise the practical challenges that school psychologists face when striving for systems-level change and have highlighted a more manageable domain within a systems-level approach – the classroom. Overall, it makes sense for school psychologists to devote considerable effort to monitoring and improving school and classroom-based performance for all children and youth because it has been shown to be an effective preventive approach.

Universal Screening

School psychologists play an important role in supporting youth mental wellness, but identifying youth who are in distress can be challenging. Some schools have implemented universal mental health screening programs to help school psychologists find and help struggling youth. For instance, schools in King County, Washington are using the Check Yourself digital screening tool designed by Seattle Children’s Hospital to measure, understand, and nurture individual students’ well-being. Check Yourself collects information about lifestyle, behaviour, and social determinants of health to identify at-risk youth so that school psychologists can intervene and direct youth to the services they need. Mental health screening provides school psychologists with valuable insights so that interventions are better fitted to student needs.

Crisis Intervention

Crisis intervention is an integral part of school psychology. School administrators view school psychologists as the school’s crisis intervention “experts”. Crisis events can significantly affect a student’s ability to learn and function effectively. Many school crisis response models suggest that a quick return to normal rituals and routines can be helpful in coping with crises. The primary goal of crisis interventions is to help crisis-exposed students return to their basic abilities of problem-solving so the student can return to their pre-crisis level of functioning.

Consultation

Consultation is done through a problem solving method that will help the consultee function more independently without the intensive support of a school psychologist.

Social Justice

The three major elements that comprise social justice include equity, fairness, and respect. The concept of social justice includes all individuals having equal access to opportunities and resources. A major component behind social justice is the idea of being culturally aware and sensitive. American Psychological Association (APA) and the National Association of School Psychologists (NASP) both have ethical principles and codes of conduct that present aspirational elements of social justice that school psychologists may abide by. Although ethical principles exist, there is federal legislation that acts accordingly to social justice. For example, the Elementary and Secondary Education Act of 1965 (ESEA) and the Individuals with Disabilities Education Improvement Act of 2004 (IDEA) address issues such as poverty and disability to promote the concept of social justice in schools.

Schools are becoming increasingly diverse with growing awareness of these differences. Cultural diversity factors that can be addressed through social justice practice include race/ethnicity, gender, socioeconomic status (SES), religion, and sexual orientation. With the various elements that can impact a student’s education and become a source of discrimination, there is a greater call for the practice of social justice in schools. School psychologists that consider the framework of social justice know that injustices that low SES students face can sometimes be different when compared to high SES students.

Advocacy

A major role of school psychologists involves advocating and speaking up for individuals as needed. Advocacy can be done at district, regional, state, or national level. School psychologists advocate for students, parents, and caregivers.

Consultation and collaboration are key components of school psychology and advocacy. There may be times when school personnel may not agree with the school psychologist. Differing opinions can be problematic because a school psychologist advocates for what is in the best interest of the student. School psychologists and staff members can help facilitate awareness through courageous conversations.

Multicultural Competence

School psychologists offer many types of services in order to be multiculturally competent. Multicultural competence extends to race, ethnicity, social class, gender, religion, sexual orientation, disability, age, and geographic region. Because the field of school psychology serves such a diverse range of students, maintaining representation for minority groups continues to be a priority. Despite such importance, history has seen an underrepresentation of culturally and linguistically diverse (CLD) school psychologists. which may appear alarming given that the diversity of our youth continues to increase exponentially. Thus, current professionals in the field have prioritised the acquisition of CLD school psychologists. School psychologists are trained to use their skills, knowledge, and professional practices in promoting diversity and advocating for services for all students, families, teachers, and schools. School psychologists may also work with teachers and educators to provide an integrated multicultural education classroom and curriculum that allows more students to be represented in learning. Efforts to increase multicultural perspectives among school psychologists have been on the rise to account for the increased diversity within schools. Such efforts include establishing opportunities for individuals representative of minority groups to become school psychologists and implementing a diverse array of CLD training programmes within the field.

Education

In order to become a school psychologist, one must first learn about school psychology by successfully completing a graduate-level training programme. A B.A. or B.S. is not sufficient.

United States

School psychology training programs are housed in university schools of education or departments of psychology. School psychology programmes require courses, practica, and internships.

Degree Requirements

Specific degree requirements vary across training programmes. School psychology training programs offer masters-level (M.A., M.S., M.Ed.), specialist-level degrees (Ed.S., Psy.S., SSP, CAGS), and doctoral-level degrees (Ph.D., Psy.D. or Ed.D.) degrees. Regardless of degree title, a supervised internship is the defining feature of graduate-level training that leads to certification to practice as a school psychologist.

Specialist-level training typically requires 3-4 years of graduate training including a 9-month (1200 hour) internship in a school setting.

Doctoral-level training programs typically require 5-7 years of graduate training. Requirements typically include more coursework in core psychology and professional psychology, more advanced statistics coursework, involvement in research endeavours, a doctoral dissertation, and a one-year (1500+ hour) internship (which may be in a school or other settings such as clinics or hospitals).

In the past, a master’s degree was considered the standard for practice in schools. As of 2017, the specialist-level degree is considered the entry-level degree in school psychology. Masters-level degrees in school psychology may lead to obtaining related credentials (such as Educational Diagnostician, School Psychological Examiner, School Psychometrist) in one or two states.

International

In the UK, the similar practice and study of School Psychology is more often termed Educational Psychology and requires a doctorate (in Educational Psychology) which then enables individuals to register and subsequently practice as a licensed educational psychologist.

Employment in the United States

In the United States, job prospects in school psychology are excellent. Across all disciplines of psychology, the abundance of opportunities is considered among the best for both specialist and doctoral level practitioners. They mostly work in schools. Other settings include clinics, hospitals, correctional facilities, universities, and independent practice.

Demographic Information

According to the NASP Research Committee, 74% of school psychologists are female with an average age of 46. In 2004-2005, average earnings for school practitioners ranged from $56,262 for those with a 180-day annual contract to $68,764 for school psychologists with a 220-day contract. In 2009-2010, average earnings for school practitioners ranged from $64,168 for those with a 180-day annual contract to $71,320 for school psychologists with a 200-day contract. For university faculty in school psychology, the salary estimate is $77,801.

Based on surveys performed by NASP in 2009-2010, it is shown that 90.7% of school psychologists are white, while minority races make up the remaining 9.3%. Of this remaining percentage, the next largest populations represented in school psychology, are African-Americans and Hispanics, at 3% and 3.4% respectively.

Shortages in the Field

There is a lack of trained school psychologists within the field. While jobs are available across the country, there are just not enough people to fill them.

Due to the low supply and high demand of school psychologists, being a school psychologist is very demanding. School psychologists may feel under pressure to supply adequate mental health and intervention services to the students in their care. Burnout is a risk of being a school psychologist.

Bilingual School Psychologists

Approximately 21% of school-age children ages 5-7 speak a language other than English. For this reason, there is an enormous demand for bilingual school psychologists in the United States. The National Association of School Psychologists (NASP) does not currently offer bilingual certification in the field. However, there are a number of professional training opportunities that bilingual LSSPs/School Psychologists can attend in order to prepare to adequately administer assessments. In addition, there are 7 NASP-Approved school psychology programs that offer a bilingual specialisation:

  • Brooklyn College-City University of New York- Specialist Level.
  • Gallaudet University- Specialist Level.
  • Queens College-City University of New York- Specialist Level.
  • San Diego State University- Specialist Level.
  • Texas State University- Specialist Level.
  • University of Colorado Denver- Doctoral Level.
  • Fordham University- Lincoln Centre – Doctoral Level.

New York and Illinois are the only two states that offer a bilingual credential for school psychologists.

International School Psychology

The role of a school psychologist in the United States and Canada may differ considerably from the role of a school psychologist elsewhere. Especially in the United States, the role of school psychologist has been closely linked to public law for education of students with disabilities. In most other nations, this is not the case. Despite this difference, many of the basic functions of a school psychologist, such as consultation, intervention, and assessment are shared by most school psychologists worldwide.

It is difficult to estimate the number of school psychologists worldwide. Recent surveys indicate there may be around 76,000 to 87,000 school psychologists practicing in 48 countries, including 32,300 in the United States and 3,500 in Canada. Following the United States, Turkey has the next largest estimated number of school psychologists (11,327), followed by Spain (3,600), and then both Canada and Japan (3,500 each).

Credentialing

In order to work as a school psychologist, one must first meet the state requirements. In most states (excluding Texas and Hawaii), a state education agency credentials school psychologists for practice in the schools.

The Nationally Certified School Psychologist (NCSP) credential offered by the National Association of School Psychologists (NASP). The NCSP credential is an example of a non-practice credential as holding the NCSP does not make one eligible to provide services without first meeting the state requirements to work as a school psychologist.

State psychology boards (which may go by different names in each state) also offer credentials for school psychologists in some states. For example, Texas offers the LSSP credential which permits licensees to deliver school psychological services within public and private schools.

What is Applied Behaviour Analysis?

Published on by Andrew Marshall2 Comments

Introduction

Applied Behaviour Analysis (ABA), also called behavioural engineering, is a scientific technique concerned with applying empirical approaches based upon the principles of respondent and operant conditioning to change behaviour of social significance.

It is the applied form of behaviour analysis; the other two forms are:

  • Radical behaviourism (or the philosophy of the science); and the
  • Experimental analysis of behaviour (or basic experimental research).

The name “applied behaviour analysis” has replaced behaviour modification because the latter approach suggested attempting to change behaviour without clarifying the relevant behaviour-environment interactions. In contrast, ABA changes behaviour by first assessing the functional relationship between a targeted behaviour and the environment. Further, the approach often seeks to develop socially acceptable alternatives for aberrant behaviours.

ABA has been utilised in a range of areas, including applied animal behaviour, schoolwide positive behaviour support, classroom instruction, structured and naturalistic early behavioural interventions for autism, paediatric feeding therapy, rehabilitation of brain injury, dementia, fitness training, substance abuse, phobias, tics, and organisational behaviour management.

ABA is considered to be controversial by some within the autism rights movement due to a perception that it emphasizes indistinguishability instead of acceptance and a history of, in some embodiments of ABA and its predecessors, the use of aversives such as electric shocks.

Definition

ABA is an applied science devoted to developing procedures which will produce observable changes in behaviour. It is to be distinguished from the experimental analysis of behaviour, which focuses on basic experimental research, but it uses principles developed by such research, in particular operant conditioning and classical conditioning. Behaviour analysis adopts the viewpoint of radical behaviourism, treating thoughts, emotions, and other covert activity as behaviour that is subject to the same rules as overt responses. This represents a shift away from methodological behaviourism, which restricts behaviour-change procedures to behaviours that are overt, and was the conceptual underpinning of behaviour modification.

Behaviour analysts also emphasize that the science of behaviour must be a natural science as opposed to a social science. As such, behaviour analysts focus on the observable relationship of behaviour with the environment, including antecedents and consequences, without resort to “hypothetical constructs”.

Brief History

The beginnings of ABA can be traced back to Teodoro Ayllon and Jack Michael’s study “The psychiatric nurse as a behavioural engineer” (1959) that they published in the Journal of the Experimental Analysis of Behaviour (JEAB). Ayllon and Michael were training the staff and nurses at a psychiatric hospital how to use a token economy based on the principles of operant conditioning for patients with schizophrenia and intellectual disability, which led to researchers at the University of Kansas to start the Journal of Applied Behaviour Analysis (JABA) in 1968.

A group of faculty and researchers at the University of Washington, including Donald Baer, Sidney W. Bijou, Bill Hopkins, Jay Birnbrauer, Todd Risley, and Montrose Wolf, applied the principles of behavior analysis to instruct developmentally disabled children, manage the behaviour of children and adolescents in juvenile detention centres, and organise employees who required proper structure and management in businesses, among other situations. In 1968, Baer, Bijou, Risley, Birnbrauer, Wolf, and James Sherman joined the Department of Human Development and Family Life at the University of Kansas, where they founded the Journal of Applied Behaviour Analysis.

Notable graduate students from the University of Washington include Robert Wahler, James Sherman, and Ivar Lovaas. Lovaas established the UCLA Young Autism Project while teaching at the University of California, Los Angeles. In 1965, Lovaas published a series of articles that outlined his system for coding observed behaviours, described a pioneering investigation of the antecedents and consequences that maintained a problem behaviour, and relied upon the methods of errorless learning that was initially devised by Charles Ferster to teach nonverbal children to speak. Lovaas also described how to use social (secondary) reinforcers, teach children to imitate, and what interventions (including electric shocks) may be used to reduce aggression and life-threatening self-injury.

In 1987, Lovaas published the study, “Behavioural treatment and normal educational and intellectual functioning in young autistic children”. The experimental group in this study received up to 40 hours per week in a 1:1 teaching setting at a table using errorless discrete trial training (DTT). The treatment is done at home with parents involved in every aspect of treatment, and the curriculum is highly individualized with a heavy emphasis on teaching eye contact, fine and gross motor imitation, and language. ABA principles were used to motivate learning and reduce non-desired behaviours. The outcome of this study indicated 47% of the experimental group (9/19) went on to lose their autism diagnosis and were described as indistinguishable from their typical adolescent peers. This included passing regular education without assistance, making and maintaining friends, and becoming self-sufficient as adults. These gains were maintained as reported in the 1993 study, “Long-term outcome for children with autism who received early intensive behavioural treatment”. Lovaas’ work went on to be recognised by the US Surgeon General in 1999, and his research were replicated in university and private settings. The “Lovaas Method” went on to become known as early intensive behavioural intervention (EIBI), or 30 to 40 hours per week of DTT.

Over the years, “behaviour analysis” gradually superseded “behaviour modification”; that is, from simply trying to alter problematic behaviour, behaviour analysts sought to understand the function of that behaviour, what antecedents promote and maintain it, and how it can be replaced by successful behaviour. This analysis is based on careful initial assessment of a behaviour’s function and a testing of methods that produce changes in behaviour.

While ABA seems to be intrinsically linked to autism intervention, it is also used in a broad range of other situations. Recent notable areas of research in JABA include autism, classroom instruction with typically developing students, paediatric feeding therapy, and substance-use disorders. Other applications of ABA include applied animal behaviour, consumer behaviour analysis, behavioural medicine, behavioural neuroscience, clinical behaviour analysis, forensic behaviour analysis, increasing job safety and performance, schoolwide positive behaviour support, and contact desensitisation for phobias.

Baer, Wolf, and Risley’s 1968 article is still used as the standard description of ABA. It lists the following seven characteristics of ABA.

  • Applied:
    • ABA focuses on the social significance of the behaviour studied.
    • For example, a non-applied researcher may study eating behaviour because this research helps to clarify metabolic processes, whereas the applied researcher may study eating behaviour in individuals who eat too little or too much, trying to change such behaviour so that it is more acceptable to the persons involved.
  • Behavioural:
    • ABA is pragmatic; it asks how it is possible to get an individual to do something effectively.
    • To answer this question, the behaviour itself must be objectively measured.
    • Verbal descriptions are treated as behaviour in themselves, and not as substitutes for the behaviour described.
  • Analytic:
    • Behaviour analysis is successful when the analyst understands and can manipulate the events that control a target behaviour.
    • This may be relatively easy to do in the lab, where a researcher is able to arrange the relevant events, but it is not always easy, or ethical, in an applied situation.
    • Baer et al. outline two methods that may be used in applied settings to demonstrate control while maintaining ethical standards.
    • These are the reversal design and the multiple baseline design.
    • In the reversal design, the experimenter first measures the behaviour of choice, introduces an intervention, and then measures the behaviour again.
    • Then, the intervention is removed, or reduced, and the behaviour is measured yet again.
    • The intervention is effective to the extent that the behaviour changes and then changes back in response to these manipulations.
    • The multiple baseline method may be used for behaviours that seem irreversible.
    • Here, several behaviours are measured and then the intervention is applied to each in turn.
    • The effectiveness of the intervention is revealed by changes in just the behaviour to which the intervention is being applied.
  • Technological:
    • The description of analytic research must be clear and detailed, so that any competent researcher can repeat it accurately.
    • Cooper et al. describe a good way to check this: Have a person trained in applied behaviour analysis read the description and then act out the procedure in detail.
    • If the person makes any mistakes or has to ask any questions then the description needs improvement.
  • Conceptually Systematic:
    • Behaviour analysis should not simply produce a list of effective interventions.
    • Rather, to the extent possible, these methods should be grounded in behavioural principles.
    • This is aided by the use of theoretically meaningful terms, such as “secondary reinforcement” or “errorless discrimination” where appropriate.
  • Effective:
    • Though analytic methods should be theoretically grounded, they must be effective.
    • If an intervention does not produce a large enough effect for practical use, then the analysis has failed
  • Generality:
    • Behaviour analysts should aim for interventions that are generally applicable; the methods should work in different environments, apply to more than one specific behaviour, and have long-lasting effects.

Other Proposed Characteristics

In 2005, Heward et al. suggested that the following five characteristics should be added:

  • Accountable:
    • To be accountable means that ABA must be able to demonstrate that its methods are effective.
    • This requires the repeatedly measuring the success of interventions, and, if necessary, making changes that improve their effectiveness.
  • Public:
    • The methods, results, and theoretical analyses of ABA must be published and open to scrutiny.
    • There are no hidden treatments or mystical, metaphysical explanations.
  • Doable:
    • To be generally useful, interventions should be available to a variety of individuals, who might be teachers, parents, therapists, or even those who wish to modify their own behaviour.
    • With proper planning and training, many interventions can be applied by almost anyone willing to invest the effort.
  • Empowering:
    • ABA provides tools that give the practitioner feedback on the results of interventions.
    • These allow clinicians to assess their skill level and build confidence in their effectiveness.
  • Optimistic:
    • According to several leading authors, behaviour analysts have cause to be optimistic that their efforts are socially worthwhile, for the following reasons:
      • The behaviours impacted by behaviour analysis are largely determined by learning and controlled by manipulable aspects of the environment.
      • Practitioners can improve performance by direct and continuous measurements.
      • As a practitioner uses behavioural techniques with positive outcomes, they become more confident of future success.
      • The literature provides many examples of success in teaching individuals considered previously unteachable.

Concepts

Behaviour

Behaviour refers to the movement of some part of an organism that changes some aspect of the environment. Often, the term behaviour refers to a class of responses that share physical dimensions or functions, and in that case a response is a single instance of that behaviour. If a group of responses have the same function, this group may be called a response class. “Repertoire” refers to the various responses available to an individual; the term may refer to responses that are relevant to a particular situation, or it may refer to everything a person can do.

Operant Conditioning

Operant behaviour is the so-called “voluntary” behaviour that is sensitive to, or controlled by its consequences. Specifically, operant conditioning refers to the three-term contingency that uses stimulus control, in particular an antecedent contingency called the discriminative stimulus (SD) that influences the strengthening or weakening of behaviour through such consequences as reinforcement or punishment. The term is used quite generally, from reaching for a candy bar, to turning up the heat to escape an aversive chill, to studying for an exam to get good grades.

Respondent (Classical) Conditioning

Respondent (classical) conditioning is based on innate stimulus-response relationships called reflexes. In his famous experiments with dogs, Pavlov usually used the salivary reflex, namely salivation (unconditioned response) following the taste of food (unconditioned stimulus). Pairing a neutral stimulus, for example a bell (conditioned stimulus) with food caused the dog to elicit salivation (conditioned response). Thus, in classical conditioning, the conditioned stimulus becomes a signal for a biologically significant consequence. Note that in respondent conditioning, unlike operant conditioning, the response does not produce a reinforcer or punisher (e.g. the dog does not get food because it salivates).

Environment

The environment is the entire constellation of stimuli in which an organism exists. This includes events both inside and outside of an organism, but only real physical events are included. A stimulus is an “energy change that affects an organism through its receptor cells”.

A stimulus can be described:

  • Topographically by its physical features.
  • Temporally by when it occurs.
  • Functionally by its effect on behaviour.

Reinforcement

Reinforcement is the key element in operant conditioning and in most behaviour change programmes. It is the process by which behaviour is strengthened. If a behaviour is followed closely in time by a stimulus and this results in an increase in the future frequency of that behaviour, then the stimulus is a positive reinforcer. If the removal of an event serves as a reinforcer, this is termed negative reinforcement. There are multiple schedules of reinforcement that affect the future probability of behaviour.

The use of punishments, especially those that inflict sensory or physical pain, is an area of controversy.

Punishment

Punishment is a process by which a consequence immediately follows a behaviour which decreases the future frequency of that behaviour. As with reinforcement, a stimulus can be added (positive punishment) or removed (negative punishment). Broadly, there are three types of punishment: presentation of aversive stimuli (e.g. pain), response cost (removal of desirable stimuli as in monetary fines), and restriction of freedom (as in a ‘time out’). Punishment in practice can often result in unwanted side effects. Some other potential unwanted effects include resentment over being punished, attempts to escape the punishment, expression of pain and negative emotions associated with it, and recognition by the punished individual between the punishment and the person delivering it.

Extinction

Extinction is the technical term to describe the procedure of withholding/discontinuing reinforcement of a previously reinforced behaviour, resulting in the decrease of that behaviour. The behaviour is then set to be extinguished. Extinction procedures are often preferred over punishment procedures, as many punishment procedures are deemed unethical and in many states prohibited. Nonetheless, extinction procedures must be implemented with utmost care by professionals, as they are generally associated with extinction bursts. An extinction burst is the temporary increase in the frequency, intensity, and/or duration of the behaviour targeted for extinction. Other characteristics of an extinction burst include an:

  • Extinction-produced aggression: the occurrence of an emotional response to an extinction procedure often manifested as aggression; and
  • Extinction-induced response variability: the occurrence of novel behaviours that did not typically occur prior to the extinction procedure.

These novel behaviours are a core component of shaping procedures.

Discriminated Operant and Three-Term Contingency

In addition to a relation being made between behaviour and its consequences, operant conditioning also establishes relations between antecedent conditions and behaviours. This differs from the S-R formulations (If-A-then-B), and replaces it with an AB-because-of-C formulation. In other words, the relation between a behaviour (B) and its context (A) is because of consequences (C), more specifically, this relationship between AB because of C indicates that the relationship is established by prior consequences that have occurred in similar contexts. This antecedent-behaviour-consequence contingency is termed the three-term contingency. A behaviour which occurs more frequently in the presence of an antecedent condition than in its absence is called a discriminated operant. The antecedent stimulus is called a discriminative stimulus (SD). The fact that the discriminated operant occurs only in the presence of the discriminative stimulus is an illustration of stimulus control. More recently behaviour analysts have been focusing on conditions that occur prior to the circumstances for the current behaviour of concern that increased the likelihood of the behaviour occurring or not occurring. These conditions have been referred to variously as “Setting Event”, “Establishing Operations”, and “Motivating Operations” by various researchers in their publications.

Verbal Behaviour

B.F. Skinner’s classification system of behaviour analysis has been applied to treatment of a host of communication disorders. Skinner’s system includes:

  • Tact: A verbal response evoked by a non-verbal antecedent and maintained by generalized conditioned reinforcement……
  • Mand: Behaviour under control of motivating operations maintained by a characteristic reinforcer.
  • Intraverbals: Verbal behaviour for which the relevant antecedent stimulus was other verbal behaviour, but which does not share the response topography of that prior verbal stimulus (e.g. responding to another speaker’s question).
  • Autoclitic: Secondary verbal behaviour which alters the effect of primary verbal behaviour on the listener. Examples involve quantification, grammar, and qualifying statements (e.g. the differential effects of “I think…” vs. “I know…”).

Measuring Behaviour

When measuring behaviour, there are both dimensions of behaviour and quantifiable measures of behaviour. In applied behaviour analysis, the quantifiable measures are a derivative of the dimensions. These dimensions are repeatability, temporal extent, and temporal locus.

  • Repeatability:
    • Response classes occur repeatedly throughout time – i.e. how many times the behaviour occurs.
    • Count is the number of occurrences in behaviour.
    • Rate/frequency is the number of instances of behaviour per unit of time.
    • Celeration is the measure of how the rate changes over time.
  • Temporal extent:
    • This dimension indicates that each instance of behaviour occupies some amount of time – i.e. how long the behaviour occurs.
    • Duration is the period of time over which the behavior occurs.
  • Temporal locus:
    • Each instance of behaviour occurs at a specific point in time – i.e. when the behaviour occurs.
    • Response latency is the measure of elapsed time between the onset of a stimulus and the initiation of the response.
    • Interresponse time is the amount of time that occurs between two consecutive instances of a response class.
  • Derivative measures:
    • Derivative measures are unrelated to specific dimensions.
    • Percentage is the ratio formed by combining the same dimensional quantities.
    • Trials-to-criterion are the number of response opportunities needed to achieve a predetermined level of performance.

Analysing Behaviour Change

Experimental Control

In applied behaviour analysis, all experiments should include the following:

  • At least one participant.
  • At least one behaviour (dependent variable).
  • At least one setting.
  • A system for measuring the behaviour and ongoing visual analysis of data.
  • At least one treatment or intervention condition.
  • Manipulations of the independent variable so that its effects on the dependent variable may be quantitatively or qualitatively analysed.
  • An intervention that will benefit the participant in some way.

Methodologies developed through ABA Research

Task Analysis

Task analysis is a process in which a task is analysed into its component parts so that those parts can be taught through the use of chaining: forward chaining, backward chaining and total task presentation. Task analysis has been used in organisational behaviour management, a behaviour analytic approach to changing the behaviours of members of an organisation (e.g. factories, offices, or hospitals). Behavioural scripts often emerge from a task analysis. Bergan conducted a task analysis of the behavioural consultation relationship and Thomas Kratochwill developed a training programme based on teaching Bergan’s skills. A similar approach was used for the development of microskills training for counsellors. Ivey would later call this “behaviourist” phase a very productive one[58] and the skills-based approach came to dominate counsellor training during 1970-1990. Task analysis was also used in determining the skills needed to access a career. In education, Englemann (1968) used task analysis as part of the methods to design the Direct Instruction curriculum.

Chaining

The skill to be learned is broken down into small units for easy learning. For example, a person learning to brush teeth independently may start with learning to unscrew the toothpaste cap. Once they have learned this, the next step may be squeezing the tube, etc.

For problem behaviour, chains can also be analysed and the chain can be disrupted to prevent the problem behaviour. Some behaviour therapies, such as dialectical behaviour therapy, make extensive use of behaviour chain analysis, but is not philosophically behaviour analytic.

Prompting

A prompt is a cue that is used to encourage a desired response from an individual. Prompts are often categorized into a prompt hierarchy from most intrusive to least intrusive, although there is some controversy about what is considered most intrusive, those that are physically intrusive or those that are hardest prompt to fade (e.g. verbal). In order to minimise errors and ensure a high level of success during learning, prompts are given in a most-to-least sequence and faded systematically. During this process, prompts are faded quickly as possible so that the learner does not come to depend on them and eventually behaves appropriately without prompting.

Types of prompts Prompters might use any or all of the following to suggest the desired response:

  • Vocal prompts: Words or other vocalisations.
  • Visual prompts: A visual cue or picture.
  • Gestural prompts: A physical gesture.
  • Positional prompt: For example, the target item is placed close to the individual.
  • Modelling: Modelling the desired response.
    • This type of prompt is best suited for individuals who learn through imitation and can attend to a model.
  • Physical prompts: Physically manipulating the individual to produce the desired response.
    • There are many degrees of physical prompts, from quite intrusive (e.g. the teacher places a hand on the learner’s hand) to minimally intrusive (e.g. a slight tap).

This is not an exhaustive list of prompts; the nature, number, and order of prompts are chosen to be the most effective for a particular individual.

Fading

The overall goal is for an individual to eventually not need prompts. As an individual gains mastery of a skill at a particular prompt level, the prompt is faded to a less intrusive prompt. This ensures that the individual does not become overly dependent on a particular prompt when learning a new behaviour or skill.

Thinning a Reinforcement Schedule

Thinning is often confused with fading. Fading refers to a prompt being removed, where thinning refers to an increase in the time or number of responses required between reinforcements. Periodic thinning that produces a 30% decrease in reinforcement has been suggested as an efficient way to thin. Schedule thinning is often an important and neglected issue in contingency management and token economy systems, especially when these are developed by unqualified practitioners (see professional practice of behaviour analysis).

Generalisation

Generalisation is the expansion of a student’s performance ability beyond the initial conditions set for acquisition of a skill. Generalisation can occur across people, places, and materials used for teaching. For example, once a skill is learned in one setting, with a particular instructor, and with specific materials, the skill is taught in more general settings with more variation from the initial acquisition phase. For example, if a student has successfully mastered learning colours at the table, the teacher may take the student around the house or school and generalise the skill in these more natural environments with other materials. Behaviour analysts have spent considerable amount of time studying factors that lead to generalisation.

Shaping

Shaping involves gradually modifying the existing behaviour into the desired behaviour. If the student engages with a dog by hitting it, then they could have their behaviour shaped by reinforcing interactions in which they touch the dog more gently. Over many interactions, successful shaping would replace the hitting behaviour with patting or other gentler behaviour. Shaping is based on a behaviour analyst’s thorough knowledge of operant conditioning principles and extinction. Recent efforts to teach shaping have used simulated computer tasks.

One teaching technique found to be effective with some students, particularly children, is the use of video modelling (the use of taped sequences as exemplars of behaviour). It can be used by therapists to assist in the acquisition of both verbal and motor responses, in some cases for long chains of behaviour.

Interventions Based on an FBA

Critical to behaviour analytic interventions is the concept of a systematic behavioural case formulation with a functional behavioural assessment or analysis at the core. This approach should apply a behaviour analytic theory of change. This formulation should include a thorough functional assessment, a skills assessment, a sequential analysis (behaviour chain analysis), an ecological assessment, a look at existing evidenced-based behavioural models for the problem behaviour (such as Fordyce’s model of chronic pain) and then a treatment plan based on how environmental factors influence behaviour. Some argue that behaviour analytic case formulation can be improved with an assessment of rules and rule-governed behaviour. Some of the interventions that result from this type of conceptualization involve training specific communication skills to replace the problem behaviours as well as specific setting, antecedent, behaviour, and consequence strategies.

Use in the Treatment of Autism Spectrum Disorders

ABA-based techniques are often used to teach adaptive behaviours or to diminish behaviours associated with autism, so much that ABA itself is often mistakenly considered to be synonymous with therapy for autism. According to a paper from 2007, it was considered to be an effective “intervention for challenging behaviors” by the American Academy of Paediatrics, though this has been refuted by more recent papers. ABA for autism may be limited by diagnostic severity and IQ.

Efficacy

Recent reviews of the efficacy of ABA-based techniques in autism include:

  • A 2007 clinical report of the American Academy of Paediatrics concluded that the benefit of ABA-based interventions in autism spectrum disorders (ASDs) “has been well documented” and that “children who receive early intensive behavioral treatment have been shown to make substantial, sustained gains in IQ, language, academic performance, and adaptive behavior as well as some measures of social behavior”.
  • Researchers from the MIND Institute published an evidence-based review of comprehensive treatment approaches in 2008. On the basis of “the strength of the findings from the four best-designed, controlled studies”, they were of the opinion that one ABA-based approach (the Lovaas technique created by Ole Ivar Løvaas) is “well-established” for improving intellectual performance of young children with ASD.
  • A 2009 review of psycho-educational interventions for children with autism whose mean age was six years or less at intake found that five high-quality (“Level 1” or “Level 2”) studies assessed ABA-based treatments. On the basis of these and other studies, the author concluded that ABA is “well-established” and is “demonstrated effective in enhancing global functioning in pre-school children with autism when treatment is intensive and carried out by trained therapists”. However, the review committee also concluded that “there is a great need for more knowledge about which interventions are most effective”.
  • A 2009 paper included a descriptive analysis, an effect size analysis, and a meta-analysis of 13 reports published from 1987 to 2007 of early intensive behavioural intervention (EIBI, a form of ABA-based treatment with origins in the Lovaas technique) for autism. It determined that EIBI’s effect sizes were “generally positive” for IQ, adaptive behaviour, expressive language, and receptive language. The paper did note limitations of its findings including the lack of published comparisons between EIBI and other “empirically validated treatment programs”.
  • In a 2009 systematic review of 11 studies published from 1987 to 2007, the researchers wrote “there is strong evidence that EIBI is effective for some, but not all, children with autism spectrum disorders, and there is wide variability in response to treatment”. Furthermore, any improvements are likely to be greatest in the first year of intervention.
  • A 2009 meta-analysis of nine studies published from 1987 to 2007 concluded that EIBI has a “large” effect on full-scale intelligence and a “moderate” effect on adaptive behaviour in autistic children.
  • A 2009 systematic review and meta-analysis by Spreckley and Boyd of four small-n 2000-2007 studies (involving a total of 76 children) came to different conclusions than the aforementioned reviews. Spreckley and Boyd reported that applied behaviour intervention (ABI), another name for EIBI, did not significantly improve outcomes compared with standard care of preschool children with ASD in the areas of cognitive outcome, expressive language, receptive language, and adaptive behaviour. In a letter to the editor, however, authors of the four studies meta-analysed claimed that Spreckley and Boyd had misinterpreted one study comparing two forms of ABI with each other as a comparison of ABI with standard care, which erroneously decreased the observed efficacy of ABI. Furthermore, the four studies’ authors raised the possibility that Spreckley and Boyd had excluded some other studies unnecessarily, and that including such studies could have led to a more favourable evaluation of ABI. Spreckley, Boyd, and the four studies’ authors did agree that large multi-site randomised trials are needed to improve the understanding of ABA’s efficacy in autism.
  • In 2011, investigators from Vanderbilt University under contract with the Agency for Healthcare Research and Quality performed a comprehensive review of the scientific literature on ABA-based and other therapies for autism spectrum disorders; the ABA-based therapies included the UCLA/Lovaas method and the Early Start Denver Model (the latter developed by Sally Rogers and Geraldine Dawson). They concluded that “both approaches were associated with … improvements in cognitive performance, language skills, and adaptive behavior skills”. However, they also concluded that “the strength of evidence … is low”, “many children continue to display prominent areas of impairment”, “subgroups may account for a majority of the change”, there is “little evidence of practical effectiveness or feasibility beyond research studies”, and the published studies “used small samples, different treatment approaches and duration, and different outcome measurements”.
  • An October 2019 report by the United States Department of Defence found that “76 percent of TRICARE beneficiaries in the ACD had little to no change in symptom presentation over the course of 12 months of applied behavior analysis (ABA) services, with an additional 9 percent demonstrating worsening symptoms.”
  • Controversy regarding ABA persists in the autism community. A 2017 study found that 46% of people with autism spectrum undergoing ABA appeared to meet the criteria for post-traumatic stress disorder (PTSD), a rate 86% higher than the rate of those who had not undergone ABA (28%). According to the researcher, the rate of apparent PTSD increased after exposure to ABA regardless of the age of the patient. However, the quality of this study has been disputed by other researchers.
  • A 2019 review article concluded ABA proponents have utilised predominantly non-verbal and neurologically different, children who are not recognised under this paradigm to have their own thought processes, basic needs, preferences, style of learning, and psychological and emotional needs, for their experiment. This also indicates a missing voice of children and nonverbal people who cannot express their view on ABA.

Use of Aversives

Some embodiments of applied behaviour analysis as devised by Ole Ivar Lovaas used aversives such as electric shocks to modify undesirable behaviour in their initial use in the 1970s, as well as slapping and shouting in the landmark 1987 study. Over time the use of aversives lessened and in 2012 their use was described as being inconsistent with contemporary practice. However, aversives have continued to be used in some ABA programs. In comments made in 2014 to the FDA, a clinician who previously worked at the Judge Rotenberg Educational Centre claimed that “all textbooks used for thorough training of applied behavior analysts include an overview of the principles of punishment, including the use of electrical stimulation.” In 2020, the FDA banned the use of electrical stimulation devices used for self-injurious or aggressive behaviour and asserted that “Evidence indicates a number of significant psychological and physical risks are associated with the use of these devices, including worsening of underlying symptoms, depression, anxiety, posttraumatic stress disorder, pain, burns and tissue damage.”

Controversy

The value of eliminating autistic behaviours is disputed by proponents of neurodiversity, who claim that it forces autistics to mask their true personalities on behalf of a narrow conception of normality. Autism advocates contend that it is cruel to try to make autistic people “normal” without consideration for how this may affect their well-being. Instead, these critics advocate for increased social acceptance of harmless autistic traits and therapies focused on improving quality of life. Julia Bascom of the Autistic Self Advocacy Network (ASAN) has said, “ASAN’s objection is fundamentally an ethical one. The stated end goal of ABA is an autistic child who is ‘indistinguishable from their peers’ – an autistic child who can pass as neurotypical. We don’t think that’s an acceptable goal. The end goal of all services, supports, interventions, and therapies an autistic child receives should be to support them in growing up into an autistic adult who is happy, healthy, and living a self-determined life.”

It has been suspected that there might be a publication bias against those research articles share a controversial account of ABA. Publication bias could lead to exaggerated estimates of intervention effects.

What is a Licensed Behaviour Analyst?

Published on by Andrew Marshall1 Comment

Introduction

A licensed behaviour analyst is a type of behavioural health professional in the United States.

They have at least a master’s degree, and sometimes a doctorate, in behaviour analysis or a related field.

Behaviour analysts apply radical behaviourism, or applied behaviour analysis, to people.

Defining the Scope of Practice

The Behaviour Analyst Certification Board (BACB) defines behaviour analysis as follows:

“The analysis. The experimental analysis of behavior (EAB) is the basic science of this field and has over many decades accumulated a substantial and well-respected research literature. This literature provides the scientific foundation for applied behavior analysis (ABA), which is both an applied science that develops methods of changing behavior and a profession that provides services to meet diverse behavioral needs. Briefly, professionals in applied behavior analysis engage in the specific and comprehensive use of principles of learning, including operant and respondent learning, in order to address behavioral needs of widely varying individuals in diverse settings. Examples of these applications include: building the skills and achievements of children in school settings; enhancing the development, abilities, and choices of children and adults with different kinds of disabilities; and augmenting the performance and satisfaction of employees in organizations and businesses.”

As the above suggests, behaviour analysis is based on the principles of operant and respondent conditioning. This places behaviour analysis as one of the dominant models of behaviour management, behavioural engineering and behaviour therapy. Behaviour analysis is an active, environmental based approach and some behaviour analytic procedures are considered highly restrictive (see least restrictive environment). For example, these service may make access to preferred items contingent on performance. This has led to abuses in the past, in particular where punishment programmes have been involved. In addition, failure to be an independent profession often leads behaviour analysts and other behaviour modifiers to have their ethical codes supplanted by those of other professions. For example, a behaviour analyst working in the hospital setting might design a token economy, a form of contingency management. He may desire to meet his ethical obligation to make the program habilitative and in the clients’ best long-term interest. The physicians and nurses in the hospital who supervise him may decide that the token economy should instead create order in the nursing routines so clients get their medication quickly and efficiently. Instead of the ethical code of the BACB and the Association for Behaviour Analysis International’s position that those receiving treatment have a right to effective treatment and a right to effective education. In addition, failure on the part of a behaviour analyst to adequately supervise his or her workers could lead to abuse. Finally, misrepresentations of the field and historical problems between academics has led to frequent calls to professionalise behaviour analysis.

In general, there is wide support within the profession for licensure.

Range of Populations Worked With

The professional practice of behaviour analysis ranges from treatment of individuals with autism and developmental disabilities to behavioural coaching and behavioural psychotherapy. In addition to treatment of mental health problems and corrections, the professional practice of behaviour analysis includes organisational behavioural management, behavioural safety and even maintaining the behavioural health of astronauts while within and beyond earth’s orbit.

Certification

The BACB offers a technical certificate in behaviour analysis. This certification is internationally recognised. This certification states the level of training and requires an exam to show a minimum level of competence to call oneself a board certified behaviour analyst (BCBA). Certification came about because of many ethical issues with behavioural interventions being delivered including the use of aversive and humiliating treatments in the name of behaviour modification. The American Psychological Association offers a diplomate (post Ph.D. and licensed certification) in behavioural psychology.

The Meaning of Certification

BACB is a private non-profit organisation without governmental powers to regulate behaviour analytic practice. While the BACB certification means that candidates have satisfied entry-level requirements in behaviour analytic training, certificants may require a government license for independent practice when treating behavioural health or medical problems. Licensed certificants must operate within the scope of their license and must practice within their areas of expertise. Where the government regulates behavior analytic services unlicensed certificants must be supervised by a licensed professional and operate within the scope of their supervisor’s license when treating disorders. Unlicensed certificants who provide behaviour analytic training for educational or optimal performance purposes do not require licensed supervision. Where the government does not regulate the treatment of medical or psychological disorders certificants should practice in accord with the laws of their state, province, or country. All certificants must practice within their personal areas of expertise.

Licensure

Recently, a move has occurred to license behaviour analysts. Licensure’s purpose is to protect the public from employing unqualified practitioners.

The model licensing act states that a person is a behaviour analyst by training and experience. The person seeking licensure must have mastered behaviour analysis by achieving a master’s degree in behaviour analysis or related subject matter. Like all other master level licensed professions the model act sets the standard for a master’s degree. This requirement states that the person has achieved textbook knowledge of behaviour analysis which can be then tested through the exam offered by the BACB or the one offered by the World Centre for Behaviour Analysis. It also requires an internship in which a behaviour analysts works under another master or Ph.D. level behaviour analyst for a period of one year (750 hours) with at least two hours/week of supervision. Finally, those 750 hours are considered tutelage time. After that, the behaviour analyst must engage in supervised practice under a behaviour analyst for a period of another 2 years (2,000 hours).

Once this process is complete, the person applies to a state board who ensures that he or she has indeed met the above conditions. Once the person is licensed public protection is still monitored by the licensing board, which makes sure that the person receives sufficient ongoing education, and the licensing board investigates ethical complaints. A licensed behaviour analyst would have equal training, knowledge, skills and abilities in their discipline as would a mental health counsellor or marriage and family therapist in their discipline. In February 2008, Indiana, Arizona, Massachusetts, Vermont, Oklahoma and other states now have legislation pending to create licensure for behaviour analysts. Pennsylvania was the first state in 2008 to license “behaviour specialists” to cover behaviour analysts. Arizona, less than three weeks later, became the first state to license “behaviour analysts.” Other states such as New York, Nevada and Wisconsin also have passed behaviour analytic licensure.

Professional Organisations

The Association for Behaviour Analysis International has a special interest group for practitioner issues, which focuses on key issues related to licensing behaviour analysts. In addition, they have a practice board and a policy board to handle legislative issues ABA:I. Finally, the association has recently put out its own model licensing act for behaviour analysts.

Association for behaviour analysis international serves as the core intellectual home for behaviour analysts. The Association for Behaviour Analysis International sponsors 2 conferences per year – one in the US and one international.
