What is a Self-Report Inventory?


A self-report inventory is a type of psychological test in which a person fills out a survey or questionnaire with or without the help of an investigator.

Self-report inventories often ask direct questions about personal interests, values, symptoms, behaviours, and traits or personality types. Inventories are different from tests in that there is no objectively correct answer; responses are based on opinions and subjective perceptions. Most self-report inventories are brief and can be taken or administered within five to 15 minutes, although some, such as the Minnesota Multiphasic Personality Inventory (MMPI), can take several hours to fully complete. They are popular because they can be inexpensive to give and to score, and their scores can often show good reliability.

There are three major approaches to developing self-report inventories:

  • Theory-guided inventories are constructed around a theory of personality or a prototype of a construct.
  • Factor analysis uses statistical methods to organize groups of related items into subscales.
  • Criterion-keyed inventories include questions that have been shown to statistically discriminate between a comparison group and a criterion group, such as people with clinical diagnoses of depression versus a control group.

Items may use any of several formats: a Likert scale with ranked options, true-false, or forced choice, although other formats such as sentence completion or visual analogue scales are possible. True-false involves questions that the individual denotes as either being true or false about themselves. Forced-choice is a set of statements that require the individual to choose one as being most representative of themselves.

If the inventory includes items from different factors or constructs, the items can be mixed together or kept in groups. Sometimes the way people answer the item will change depending on the context offered by the neighbouring items.

Personality Inventories

Self-report personality inventories include questions dealing with behaviours, responses to situations, characteristic thoughts and beliefs, habits, symptoms, and feelings. Test-takers-are usually asked to indicate how well each item describes themselves or how much they agree with each item. Formats are varied, from adjectives such as “warm”, to sentences such as “I like parties”, or reports of behaviour “I have driven past the speed limit” and response formats from yes/no to Likert scales, to continuous “slider” responses. Some inventories are global, such as the NEO, others focus on particular domains, such as anger or aggression.


Unlike IQ tests where there are correct answers that have to be worked out by test takers, for personality, attempts by test-takers to gain particular scores are an issue in applied testing. Test items are often transparent, and people may “figure out” how to respond to make themselves appear to possess whatever qualities they think an organisation wants. In addition, people may falsify good responses, be biased towards their positive characteristics, or falsify bad, stressing negative characteristics, in order to obtain their preferred outcome. In clinical settings patients may exaggerate symptoms in order to make their situation seem worse, or under-report the severity or frequency of symptoms in order to minimise their problems. For this reason, self-report inventories are not used in isolation to diagnose a mental disorder, often used as screeners for verification by other assessment data. Many personality tests, such as the MMPI or the MBTI add questions that are designed to make it difficult for a person to exaggerate traits and symptoms. They are in common use for measuring levels of traits, or for symptom severity and change. Clinical discretion is advised for all self-report inventories.

Items may differ in social desirability, which can cause different scores for people at the same level of a trait, but differing in their desire to appear to possess socially desirable behaviours.

What is the Goldberg Test?


Goldberg test may refer to any of various psychiatric tests used to assess mental health in general or as screening tools for specific mental disorders e.g. depression or bipolar disorder.

Goldberg, after whom some psychiatric tests are named, might be one of two psychiatrists who share the same last name:

  • Ivan Goldberg, an American psychiatrist; and
  • Sir David Goldberg, a British psychiatrist.

Psychiatric screening tests generally do not substitute getting help from professionals.

Tests Developed by Ivan K. Goldberg

  • Goldberg Depression Test is an 18-question screening tool for depression.
  • Goldberg Mania Scale is an 18-question screening test for mania.

Tests developed by Sir David Goldberg

  • General Health Questionnaire or Goldberg Health Questionnaire (GHQ):
    • Developed in 1972 in its initial format as a 60-question test (GHQ-60) with a four-point scale for each question.
    • It is used to measure the risk of developing psychiatric disorders.
    • Other forms of GHQ are:
      • GHQ-30;
      • GHQ-28; and
      • GHQ-12.
  • Together with Simpson, they developed Personal Health Questionnaire (PHQ) in 1995.
    • It is a 10-question screening instrument for depression.
    • It should not be confused with the 9-question patient health questionnaire (PHQ-9) developed by Spitzer also to quantify the risk for depression.
    • Personal Health Questionnaire is sometimes abbreviated as PHQ-G to differentiate it from PHQ-9.
