What is Motivational Interviewing?

Introduction

Motivational interviewing (MI) is a counselling approach developed in part by clinical psychologists William R. Miller and Stephen Rollnick. It is a directive, client-centred counselling style for eliciting behaviour change by helping clients to explore and resolve ambivalence. Compared with non-directive counselling, it is more focused and goal-directed, and departs from traditional Rogerian client-centred therapy through this use of direction, in which therapists attempt to influence clients to consider making changes, rather than engaging in non-directive therapeutic exploration. The examination and resolution of ambivalence is a central purpose, and the counsellor is intentionally directive in pursuing this goal. MI is most centrally defined not by technique but by its spirit as a facilitative style for interpersonal relationship.

Core concepts evolved from experience in the treatment of problem drinkers, and MI was first described by Miller (1983) in an article published in the journal Behavioural and Cognitive Psychotherapy. Miller and Rollnick elaborated on these fundamental concepts and approaches in 1991 in a more detailed description of clinical procedures.

Overview

Motivational interviewing (MI) is a person-centred strategy. It is used to elicit patient motivation to change a specific negative behaviour. MI engages clients, elicits change talk and evokes patient motivation to make positive changes. For example, change talk can be elicited by asking the patient questions such as: “How might you like things to be different?” or “How does __ interfere with things that you would like to do?”

Unlike clinical interventions and treatment, MI is the technique where the interviewer (clinician) assists the interviewee (patient) in changing a behaviour by expressing their acceptance of the interviewee without judgement. By this, MI incorporates the idea that every single patient may be in differing stages of readiness levels and may need to act accordingly to the patient’s levels and current needs. Change may occur quickly or may take considerable time, depending on the client. Knowledge alone is usually not sufficient to motivate change within a client, and challenges in maintaining change should be thought of as the rule, not the exception. The incorporation of MI can help patients resolve their uncertainties and hesitancies that may stop them from their inherent want of change in relation to a certain behaviour or habit. At the same time, it can be seen that MI ensures that the participants are viewed more as team members to solve a problem rather than a clinician and patient. Hence, this technique can be attributed to a collaboration that respects sense of self and autonomy.

To be more successful at motivational interviewing, a clinician must have a strong sense of “purpose, clear strategies and skills for such purposes”. This ensures that the clinician knows what goals they are trying to achieve prior to entering into motivational interviewing. Additionally, clinicians need to have well-rounded and established interaction skills including asking open ended questions, reflective listening, affirming and reiterating statements back to the patient. Such skills are used in a dynamic where the clinician actively listens to the patient then repackages their statements back to them while highlighting what they have done well. In this way, it can improve their self-confidence for change.

Furthermore, at the same time the clinician needs to keep in mind the following five principles when practicing MI.

Express Empathy

This means to listen and express empathy to patients through the use of reflective listening. In this step, the clinician listens and presents ideas the patient has discussed in a different way, rather than telling the patient what to do. This hopes to ensure that the patient feels respected and that there are no judgments given when they express their thoughts, feelings and experiences but instead, shows the patient that the clinician is genuinely interested about the patient and their circumstances. This aims to strengthen the relationship between the two parties and ensures it is a collaboration, and allows the patient to feel that the clinician is supportive and therefore will be more willing to be open about their real thoughts.

Develop Discrepancy

This means to assist patients in developing discrepancies between the current self and what they want to be like in the future after a change has taken place. The main goal of this principle is to increase the patient’s awareness that there are consequences to their current behaviours. This allows the patient to realize the negatives aspects and issues the particular behaviour that MI is trying to change can cause. This realisation can help and encourage the patient towards a dedication to change as they can see the discrepancy between their current behaviour and desired behaviour. It is important that the patient be the one making the arguments for change and realise their discrepancies themselves. An effective way to do this is for the clinician to participate in active reflective listening and repacking what the patient has told them and delivering it back to them.

Avoid Arguments

During the course of MI the clinician may be inclined to argue with a patient, especially when they are ambivalent about their change and this is especially true when “resistance” is met from the patient. If the clinician tries to enforce a change, it could exacerbate the patient to become more withdrawn and can cause degeneration of what progress had been made thus far and decrease rapport with the patient. Arguments can cause the patient to become defensive and draw away from the clinician which is counterproductive and diminishes any progress that may have been made. When patients become a little defensive and argumentative, it usually is a sign to change the plan of attack. The biggest progress made towards behaviour change is when the patient makes their own arguments instead of the clinician presenting it to them.

Roll with Resistance

“Rolling with resistance” is now an outdated concept in MI; in the third edition of Miller & Rollnick’s textbook Motivational Interviewing: Helping People Change, the authors indicated that they had completely abandoned the word “resistance” as well as the term “rolling with resistance”, due to the term’s tendency to blame the client for problems in the therapy process and obscure different aspects of ambivalence. “Resistance”, as the idea was previously conceptualised before it was abandoned in MI, can come in many forms such as arguing, interrupting, denying and ignoring. Part of successful MI is to approach the “resistance” with professionalism, in a way that is non-judgmental and allows the patient to once again affirm and know that they have their autonomy and that it is their choice when it comes to their change.

Support Self-Efficacy

Strong self-efficacy can be a significant predictor of success in behaviour change. In many patients there is an issue of the lack of self-efficacy. They may have tried multiple times on their own to create a change in their behaviour (e.g. trying to cease smoking, losing weight, sleep earlier) and because they have failed it causes them to lose their confidence and hence lowers their self-efficacy. Therefore, it is clear to see how important it is for the patient to believe that they are self-efficient and it is the clinician’s role to support them by means of good MI practice and reflective listening. By reflecting on what the patient had told them, the clinician can accentuate the patient’s strengths and what they have been successful in (e.g. commending a patient who had stopped smoking for a week instead of straining on the fact they failed). By highlighting and suggesting to the patient areas in which they have been successful, this can be incorporated into future attempts and can improve their confidence and efficacy to believe that they are capable of change.

While there are as many differences in technique, the underlying spirit of the method remains the same and can be characterized in a few key points:

  • Motivation to change is elicited from the client, and is not imposed from outside forces.
  • It is the client’s task, not the counsellor’s, to articulate and resolve the client’s ambivalence.
  • Direct persuasion is not an effective method for resolving ambivalence.
  • The counselling style is generally quiet and elicits information from the client.
  • The counsellor is directive, in that they help the client to examine and resolve ambivalence.
  • Readiness to change is not a trait of the client, but a fluctuating result of interpersonal interaction.
  • The therapeutic relationship resembles a partnership or companionship.

Ultimately, practitioners must recognize that motivational interviewing involves collaboration not confrontation, evocation not education, autonomy rather than authority, and exploration instead of explanation. Effective processes for positive change focus on goals that are small, important to the client, specific, realistic, and oriented in the present and/or future.

Four Processes

There are four steps used in motivational interviewing. These help to build trust and connection between the patient and the clinician, focus on areas that may need to be changed and find out the reasons the patient may have for changing or holding onto a behaviour. This helps the clinician to support and assist the patient in their decision to change their behaviour and plan steps to reach this behavioural change. These steps do not always happen in this order.

Engaging

In this step, the clinician gets to know the patient and understands what is going on in the patient’s life. The patient needs to feel comfortable, listened to and fully understood from their own point of view. This helps to build trust with the patient and builds a relationship where they will work together to achieve a shared goal. The clinician must listen and show empathy without trying to fix the problem or make a judgement. This allows the patient to open up about their reasons for change, hopes, expectations as well as the barriers and fears that are stopping the patient from changing. The clinician must ask open ended questions which helps the patient to give more information about their situation, so they feel in control and that they are participating in the decision-making process and the decisions are not being made for them. This creates an environment that is comfortable for the patient to talk about change. The more trust the patient has towards the clinician, the more likely it is reduce resistance, defensiveness, embarrassment or anger the patient may feel when talking about a behavioural issue. Overall, the patient is more likely to come back to follow up appointments, follow an agreed plan and get the benefit of the treatment.

Focusing

This is where the clinician helps the patient find and focus on an area that is important to them, where they are unsure or are struggling to make a change. This step is also known as the “WHAT?” of change. The goal is for the clinician to understand what is important to the patient without pushing their own ideas on the patient. The clinician needs to ask questions to understand the reasons if and why the patient would be motivated to change and choose a goal to reach together. The patient must feel that they share the control with the clinician about the direction and agree on a goal. The clinician will then aim to help the patient order the importance of their goals and point out the current behaviours that get in the way of achieving their new goal or “develop discrepancy” between their current and desired behaviours. The focus or goal can come from the patient, situation or the clinician. There are three styles of focusing; directing, where the clinician can direct the patient towards a particular area for change; following, where the clinician let the patient decide the goal and be led by the patient’s priorities, and; guiding, where the clinician leads the patient to uncover an area of importance.

Evoking

In this step the clinician asks questions to get the patient to open up about their reasons for change. This step is also known as the “WHY?” of change. Often when a patient puts this into words it reinforces their reasons to change and they find out they have more reasons to change rather than to stay the same. Usually, there is one reason that is stronger than the others to motivate the patient to change their behaviour. The clinician needs to listen and recognise “change talk”, where the patient is uncovering how they would go about change and are coming up with their own solutions to their problems. The clinician should support and encourage the patient when they talk about ways and strategies to change, as the patient is more likely to follow a plan they set for themselves. When the patient is negative or is resisting change the clinician should “roll with resistance” where they do not affirm or encourage the negative points but highlight the ways and reasons the person has come up with to change. The clinician must resist arguing or the “righting reflex” where they want to fix the problem or challenge the patient’s negative thoughts. This comes across as they are not working together and causes the patient to resist change even more. The clinician’s role is to ask questions that guide the patient to come up with their own solution to change. The best time to give advice is if the patient asks for it, if the patient is stuck with coming up with ideas, the clinician can ask permission to give advice and then give details, but only after the patient has come up with their own ideas first. If the clinician focuses more on their own reasons they believe the patient should change this would not come across as genuine to the patient and this would reduce the bond they made in the engaging process.

Planning

In this step the clinician helps the patient in planning how to change their behaviour and encourages their commitment to change. This step is also known as the “HOW?” of change. The clinician asks questions to judge how ready the patient is to change and helps to guide the patient in coming up with their own step by step action plan. They can help to strengthen the patient’s commitment to changing, by supporting and encouraging when the patient uses “commitment talk” or words that show their commitment to change. In this step the clinician can listen and recognise areas that may need more work to get to the core motivation to change or help the patient to overcome uneasiness that is still blocking their behavioural change. In doing this, they help to strengthen the patients motivation and support that they are capable of achieving this goal on their own. The clinician should help the patient to come up with SMART goals which are; Specific, Measurable, Achievable, Relevant and Time bound. This helps to set benchmarks and measure how their behaviour has changed towards their new goal.

Adaptations

Motivational Enhancement Therapy

Motivational enhancement therapy is a time-limited four-session adaptation used in Project MATCH, a US-government-funded study of treatment for alcohol problems and the Drinkers’ Check-up, which provides normative-based feedback and explores client motivation to change in light of the feedback.

Motivational interviewing is supported by over 200 randomised controlled trials across a range of target populations and behaviours including substance abuse, health-promotion behaviours, medical adherence, and mental health issues.

Motivational Interviewing Groups

MI groups are highly interactive, focused on positive change, and harness group processes for evoking and supporting positive change. They are delivered in four phases:

  1. Engaging the group.
  2. Evoking member perspectives.
  3. Broadening perspectives and building momentum for change.
  4. Moving into action.

Behaviour Change Counselling

Behaviour change counselling (BCC) is an adaptation of MI which focuses on promoting behaviour change in a healthcare setting using brief consultations. BCC’s main goal is to understand the patient’s point of view, how they’re feeling and their idea of change. It was created with a “more modest goal in mind”, as it simply aims to “help the person talk through the why and how of change” and encourage behaviour change. It focuses on patient-centred care and is based on several overlapping principles of MI, such as respect for patient choice, asking open-ended questions, empathetic listening and summarizing. Multiple behaviour change counselling tools were developed to assess and scale the effectiveness of behaviour change counselling in promoting behaviour change such as the Behaviour Change Counselling Index (BECCI) and the Behaviour Change Counselling Scale (BCCS).

Behaviour Change Counselling Scale


The Behaviour Change Counselling Scale (BCCS) is a tool used to assess lifestyle counselling using BCC, focusing on feedback on the skill achieved. “Items of BCCS were scored on 1-7 Likert scales and items were tallied into 4 sub-scales, reflecting the 3 skill-sets: MI and readiness assessment, behaviour modification, and emotion management”.

The data obtained is then presented on: item characteristics, sub-scale characteristics, interrater reliability, test-retest reliability and construct validity.

Based on a study conducted by Vallis, the results suggest that BCCS is a potentially useful tool in assessing BCC and aid to training practitioners as well as assessing training outcomes.

Behaviour Change Counselling Index

The Behaviour Change Counselling Index (BECCI) is a BCC tool that assesses general practitioner behaviour and incites behaviour change through talking about change, encouraging the patient to think about change and respecting the patient’s choices in regards to behaviour change. BECCI was developed to assess a practitioner’s competence in the use of Behaviour Change Counselling (BCC) methods to elicit behaviour change. Used primarily for the use of learning practitioners in a simulated environment to practice and learn the skills of BCC. It “provides valuable information about the standard of BCC that practitioners were trained to deliver in studies of BCC as an intervention”. Rather than the result and response from the patient, the tool emphasizes and measures the practitioner’s behaviours, skills and attitude. Results from the study show that after receiving training in BCC, practitioners show great improvement based on BECCI. However, as BECCI has only been used in a simulated clinical environment, more study is required to assess its reliability in a real patient environment. Furthermore, it focuses heavily on practitioner behaviour rather than patient behaviour. Therefore, BECCI may be useful for trainers to assess the reliability and effectiveness of BCC skills but further research and use is required, especially in a real consultation environment.

Technology Assisted Motivational Interview

Technology Assisted Motivational Interview (TAMI) is “used to define adaptations of MI delivered via technology and various types of media”. This may include technological devices and creations such as computers, mobile phones, telephones, videos and animations. A review of multiple studies shows the potential effectiveness of the use of technology in delivering motivational interviewing consultations to encourage behaviour change. However, some limitations include: the lack of empathy that may be expressed through the use of technology and the lack of face-to-face interaction may either produce a positive or negative effect on the patient. Further studies are required to determine whether face-to-face consultations to deliver MI is more effective in comparison to those delivered via technology.

Limitations

Underlying Mental Health Conditions

Patients with an underlying mental illness present one such limitation to motivational interviewing. In a case where the patient suffers from an underlying mental illness such as depression, anxiety, bipolar disease, schizophrenia or other psychosis, more intensive therapy may be required to induce a change. In these instances, the use of motivational interviewing as a technique to treat outward-facing symptoms, such as not brushing teeth, may be ineffective where the root cause of the problem stems from the mental illness. When working with these patients, it is important to recognise that only so much can be done at certain levels. The treating therapists should, therefore, ensure the patient is referred to the correct medical professional to treat the cause of the behaviour, and not simply one of the symptoms.

Pre-Contemplation

Patients in the pre-contemplation stage of the stages of change present a further limitation to the model. If the patient is in this stage, they will not consider they have a problem and therefore are unlikely to be receptive to motivational interviewing techniques. It is important that motivational interviewers are well trained in the approach to be taken when handling these patients. Well intended messages can have the opposite effect of pushing the patient away or causing them to actively rebel. In these instances discussing how the issue may be affecting the patient must be handled very delicately and introduced carefully. Suggesting less harmful ways of dealing with the client’s issue and helping them recognize danger signs may be a better approach to plant the seed aiding their progression to the contemplation stage.

Motivation

Professionals attempting to encourage people to make a behavioural change often underestimate the effect of motivation. Simply advising clients how detrimental their current behaviour is and providing advice on how to change their behaviour will not work if the client lacks motivation. Many people have full knowledge of how dangerous smoking is yet they continue the practice. Research has shown that a client’s motivation to alter behaviour is largely influenced by the way the therapist relates to them.

Therapist/Client Trust

Clients who do not like or trust their health care professionals are likely to become extremely resistant to change. In order to prevent this, the therapist must take time to foster an environment of trust. Even when the therapist can clearly identify the issues at hand it is important to have the patient feels the session is collaborative and that they are not being lectured to. Confrontational approaches by well-meaning therapists will inhibit the process.

Time Limitations

Time limits placed on therapists during consultations also have the potential to impact significantly on the quality of motivational interviewing. Appointments may be limited to a brief or single visit with a patient; for example, a client may attend the dentist with a toothache due to a cavity. The oral health practitioner or dentist may be able to broach the subject of a behaviour change, such as flossing or diet modification but the session duration may not be sufficient when coupled with other responsibilities the health practitioner has to the health and wellbeing of the patient. For many clients, changing habits may involve reinforcement and encouragement which is not possible in a single visit. Some patients, once treated, may not return for a number of years or may even change practitioners or practices, meaning the motivational interview is unlikely to have sufficient effect.

Training Deficiencies

While psychologists, mental health counsellors, and social workers are generally well trained and practiced in delivering motivational interviewing, other health-care professionals are generally provided with only a few hours of basic training. Although perhaps able to apply the underpinning principles of motivational interviewing, these professionals generally lack the training and applied skills to truly master the art of dealing with the patient’s resistant statements in a collaborative manner. It is important that therapists know their own limitations and are prepared to refer clients to other professionals when required.

Group Treatment

Although studies are somewhat limited, it appears that delivering motivational interviewing, in a group may be less effective than when delivered one-on-one. Research continues into this area however what is clear is that groups change the dynamics of a situation and the therapist needs to ensure that group control is maintained and input from group members does not derail the process for some clients.

Applications

Motivational interviewing was initially developed for the treatment of substance abuse, but MI is continuously being applied across health fields and beyond that. The following fields have used the technique of MI.

Brief Intervention

Brief intervention and MI are both techniques used to empower behavioural change within individuals. Behavioral interventions “generally refer to opportunistic interventions by non-specialists (e.g. GPs) offered to patients who may be attending for some unrelated condition”. Due to speculation in the health industry the use of brief intervention has been deemed to be used too loosely and the implementation of MI is increasing rapidly.

Classroom Management

Motivational interviewing has been incorporated into managing a classroom. Due to the nature of MI where it elicits and evokes behavioural change within an individual it has shown to be effective in a classroom especially when provoking behaviour change within an individual. In association with MI, the classroom check-up method is incorporated which is a consultation model that addresses the need for classroom level support.

Coaching

Motivational interviewing has been implemented in coaching, specifically health-based coaching to aid in a better lifestyle for individuals. A study titled “Motivational interviewing-based health coaching as a chronic care intervention” was conducted to evaluate if MI had an impact on individuals health who were assessed as chronically ill. The study’s results showed that the group that MI was applied to had “improved their self-efficacy, patient activation, lifestyle change and perceived health status”.

Environmental Sustainability

Initially motivational interviewing was implemented and formulated to elicit behavioural change in individuals suffering from substance abuse. However, MI has been reformed and has multiple uses. One of these uses include of stabilising the surrounding environment of an individual. This is completed by allowing the individual to evoke behavioural change within themselves and elicit motivation to change certain habits, for example substance abuse. By motivating the individual, it allows them to maintain the environment surrounding them to eliminate factors of temptation. However, if relapse occurs it is normal and is bound to happen.

Mental Disorders

Motivational interviewing was originally developed by William R. Miller and Stephen Rollnick in the 1980s in order to aid people with substance abuse disorders. However, it has also been implemented to help aid in established models with mental disorders such as anxiety and depression. Currently an established model known as cognitive behavioural therapy (CBT) is being implemented to aid in these issues. Research suggests that with collaborating motivational interviewing and CBT has proved to be effective as they have both shown to be effective. A study was conducted as a randomised cluster trial that suggests that when MI was implemented it “associated with improved depressive symptoms and remission rate”. There is currently insufficient research papers to prove the effect of MI in mental disorders. However, it is increasingly being applied and more research is going into it.

Dual Diagnosis

Dual diagnosis can be defined as a “term that is used to describe when a person is experiencing both mental health problems and substance misuse”. Motivational interviewing is used as a preventative measure for individuals suffering from both a mental health issue and substance misuse due to the nature of MI eliciting behavioural change in individuals.

Problem Gambling

Gambling issues are on the rise and it is becoming a struggle for therapists to maintain it. Research suggests that many individuals “even those who actively seek and start gambling treatment, do not receive the full recommended course of therapy”. Motivational interviewing has been widely used and adapted by therapists to overcome gambling issues, it is used in collaboration with cognitive behavioural therapy and self-directed treatments. The goal of using MI in an individual who is having issues with gambling is to recognize and overcome those barriers and “increase overall investment in therapy by supporting an individual’s commitment to changing problem behaviours”.

Parenting

Motivational interviewing is implemented to evoke behavioural change in an individual. Provoking behavioural change includes the recognising of the issue from an individual. A research was conducted by utilising motivational interviewing to help promote oral regime and hygiene within children under the supervision of a parent. In this research the experimental group which was parents who received MI education in the form of a “pamphlet, watched a videotape, as well as received an MI counselling session and six follow-up telephone calls”. The mothers who had received the MI counselling session showed that “children in the MI group exhibited significantly less new caries (decayed or filled surfaces)” in contrast to the children in the control group. This suggests that the application of MI with parenting can significantly impact outcomes regarding the children of the parent.

Substance Dependence

Motivational interviewing was initially developed in order to aid people with substance abuse, specifically alcohol. Due to the results it displayed MI can be implemented into any substance abuse or dependence treatment. Research that was conducted utilised MI with a cocaine-detoxification programme. This research had found that out of the 105 randomly assigned patients, the randomly assigned group that underwent MI treatment indicated that “completers who received MI increased use of behavioural coping strategies and had fewer cocaine-positive urine samples on beginning the primary treatment”. This evidence suggests that the application of MI in substance dependent individuals has a positive impact in aiding the individual to overcome this issue.

A 2016 Cochrane review focused on alcohol misuse in young adults in 84 trials found no substantive, meaningful benefits for MI for preventing alcohol misuse or alcohol-related problems.
