Comrey Personality Scales

Last updated

The Comrey Personality Scales (also known as Comrey Personality Test or CPT) is a personality test developed by Andrew L. Comrey in 1970. The CPT measures eight main scales and two validity scales. [1] The test is currently distributed by Educational and Industrial Testing Service. The test consists of 180 items rated on a seven-point scale. [2]

History and development

Comrey started developing the CPT since 1961 and intended the test to improve upon prior personality tests, which he viewed as possibly creating spurious relationships between the test items and the resulting personality dimensions. In order to do this, Comrey used a technique called factored homogenous item dimension (FHID) to increase the validity of the personality dimensions that are generated during factor analysis. His first attempt was to use the technique to generate personality dimensions from the taxonomies of Hans Eysenck, Raymond B. Cattell, J. P. Guilford, as well as the Minnesota Multiphasic Personality Inventory, which eventually yielded the first six personality dimensions of CPT. [3] [4]

Several dimensions were added to the CPT when the concurrent validity of the CPT was tested with the Guilford-Zimmerman Temperament Survey (GZTS). The Socialization personality dimension was added to the COT when the tests showed items that measured the existence of this dimension, even though neither test distinguished the dimension separately. The GZTS also measured three personality dimensions that did not exist in the CPT, which were General Activity, Masculinity, and Thoughtfulness. [5] The first two dimensions were eventually incorporated in the final version of the CPT under the Activity VS. Lack of energy scale (A) and the Masculinity vs. Femininity scale (M). [6]

Additional validity testing with Cattell's 16PF and the Eysenck Personality Questionnaire also created changes to the scale. The Shyness dimension was separated into two distinct scales, and the dimension was later reconceptualized as Extraversion-Introversion. [7] Despite all the changes to the test, the CPT was finalized in 1970 with the publication of its manual. [6]

Scales

Throughout the development of the test, the CPT's eight personality dimensions were known under different names, but in its final version, they are known as the acronym TOCASEMP, and represented two extreme sides of a personality dimension. [2] [6] Each scale is represented by five factors, as detailed below.

Test format

The CPT consists of 180 items measuring the TOCASEMP personality dimensions in eight scales measuring and two scales measuring response validity. These two scales are intended to check for possible confounding variable that would render the test result as invalid, including social desirability bias.  Some of the items in CPT are reverse-coded. CPT uses two response scales to answer each items, each ranging from the value 1 to 7, which were defined differently. [2] [6]

Psychometric properties

Since its initial inception, the CPT has proven to be a robust test, both in terms of validity and reliability. Besides its use of FHID to corroborate the CPT's internal validity, where it had yielded factor loadings from r = 0.30 to r = 0.84, Comrey also used several external validity procedures¸ including several concurrent validity testing with other personality indicators, such as the 16 PF. Although changes to the test occurred following the validation, factor analysis and correlation of the test items supported the existence and structure of the CPT's personality dimensions. [4] [5] [6]

During the early stages of CPT's development, a construct validity testing on the test was also conducted on the biographical information provided by 209 university students in the United States. The findings in this study supported the existence of the eight personality dimensions of the CPT based on correlations with the research subject's data, such as marijuana consumption and high scorers in the C scale. [8]

Usage

The CPT is intended for use on the adult general population and has also been validated for usage in Italy, Brazil, South African (in Afrikaans language), and Russian populations. [6] [9] [10] [11]

Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally covers specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales.

In personality typology, the Myers–Briggs Type Indicator (MBTI) is an introspective self-report questionnaire indicating differing psychological preferences in how people perceive the world and make decisions. It enjoys popularity despite being widely regarded as pseudoscience by the scientific community. The test attempts to assign a binary value to each of four categories: introversion or extraversion, sensing or intuition, thinking or feeling, and judging or perceiving. One letter from each category is taken to produce a four-letter test result representing one of sixteen possible personalities, such as "INFP" or "ESTJ".

Psychological testing refers to the administration of psychological tests. Psychological tests are administered or scored by trained evaluators. A person's responses are evaluated according to carefully prescribed guidelines. Scores are thought to reflect individual or group differences in the construct the test purports to measure. The science behind psychological testing is psychometrics.

Cronbach's alpha, also known as tau-equivalent reliability or coefficient alpha, is a reliability coefficient and a measure of the internal consistency of tests and measures.

In psychology, trait theory is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of traits, which can be defined as habitual patterns of behavior, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals, are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions.

<span class="mw-page-title-main">Personality test</span> Method of assessing human personality constructs

A personality test is a method of assessing human personality constructs. Most personality assessment instruments are in fact introspective self-report questionnaire measures or reports from life records (L-data) such as rating scales. Attempts to construct actual performance tests of personality have been very limited even though Raymond Cattell with his colleague Frank Warburton compiled a list of over 2000 separate objective tests that could be used in constructing objective personality tests. One exception however, was the Objective-Analytic Test Battery, a performance test designed to quantitatively measure 10 factor-analytically discerned personality trait dimensions. A major problem with both L-data and Q-data methods is that because of item transparency, rating scales and self-report questionnaires are highly susceptible to motivational and response distortion ranging all the way from lack of adequate self-insight to downright dissimulation depending on the reason/motivation for the assessment being undertaken.

Raymond Bernard Cattell was a British-American psychologist, known for his psychometric research into intrapersonal psychological structure. His work also explored the basic dimensions of personality and temperament, the range of cognitive abilities, the dynamic dimensions of motivation and emotion, the clinical dimensions of abnormal personality, patterns of group syntality and social behavior, applications of personality research to psychotherapy and learning theory, predictors of creativity and achievement, and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains. Cattell authored, co-authored, or edited almost 60 scholarly books, more than 500 research articles, and over 30 standardized psychometric tests, questionnaires, and rating scales. According to a widely cited ranking, Cattell was the 16th most eminent, 7th most cited in the scientific journal literature, and among the most productive psychologists of the 20th century. He was a controversial figure due in part to his friendships with, and intellectual respect for, white supremacists and neo-Nazis.

The Sixteen Personality Factor Questionnaire (16PF) is a self-report personality test developed over several decades of empirical research by Raymond B. Cattell, Maurice Tatsuoka and Herbert Eber. The 16PF provides a measure of personality and can also be used by psychologists, and other mental health professionals, as a clinical instrument to help diagnose psychiatric disorders, and help with prognosis and therapy planning. The 16PF can also provide information relevant to the clinical and counseling process, such as an individual's capacity for insight, self-esteem, cognitive style, internalization of standards, openness to change, capacity for empathy, level of interpersonal trust, quality of attachments, interpersonal needs, attitude toward authority, reaction toward dynamics of power, frustration tolerance, and coping style. Thus, the 16PF instrument provides clinicians with a normal-range measurement of anxiety, adjustment, emotional stability and behavioral problems. Clinicians can use 16PF results to identify effective strategies for establishing a working alliance, to develop a therapeutic plan, and to select effective therapeutic interventions or modes of treatment. It can also be used within other areas of psychology, such as career and occupational selection.

The Maslach Burnout Inventory(MBI) is a psychological assessment instrument comprising 22 symptom items pertaining to occupational burnout. The original form of the MBI was developed by Christina Maslach and Susan E. Jackson with the goal of assessing an individual's experience of burnout. As underlined by Schaufeli (2003), a major figure of burnout research, "the MBI is neither grounded in firm clinical observation nor based on sound theorising. Instead, it has been developed inductively by factor-analysing a rather arbitrary set of items" (p. 3). The instrument takes 10 minutes to complete. The MBI measures three dimensions of burnout: emotional exhaustion, depersonalization, and personal accomplishment.

<span class="mw-page-title-main">Exploratory factor analysis</span> Statistical method in psychology

In multivariate statistics, exploratory factor analysis (EFA) is a statistical method used to uncover the underlying structure of a relatively large set of variables. EFA is a technique within factor analysis whose overarching goal is to identify the underlying relationships between measured variables. It is commonly used by researchers when developing a scale and serves to identify a set of latent constructs underlying a battery of measured variables. It should be used when the researcher has no a priori hypothesis about factors or patterns of measured variables. Measured variables are any one of several attributes of people that may be observed and measured. Examples of measured variables could be the physical height, weight, and pulse rate of a human being. Usually, researchers would have a large number of measured variables, which are assumed to be related to a smaller number of "unobserved" factors. Researchers must carefully consider the number of measured variables to include in the analysis. EFA procedures are more accurate when each factor is represented by multiple measured variables in the analysis.
