Personality Research Form E (PRF)
The PRF is designed to yield scores for personality traits relevant to the functioning of individuals in a wide variety of situations. Based to a large extent upon Murray’s framework for the description of personality, the PRF focuses on areas of normal functioning rather than psychopathology. Five forms of the test are available. Form E, the most popular form, contains 22 scales comprised of 352 True-False items. Test completion generally requires 45 minutes. Items were selected on the basis of simplicity of wording, content saturation, and interscale independence through use of an algorithm for minimum redundancy item analysis. The manual contains norms from the sixth grade through high school and college. Scales on Form E include: Abasement, Achievement, Affiliation, Aggression, Autonomy, Change, Cognitive Structure, Defendence, Dominance, Endurance, Exhibition, Harmavoidance, Impulsivity, Nurturance, Order, Play, Sentience, Social Recognition, Succorance, Understanding, Infrequency, Desirability.
Reliability and Validity
Considerable attention was devoted to the development of test forms combining a concise, convenient format with the properties of reliability, substantive generalizability, and validity. Unusually extensive item pools were developed which were subsequently edited carefully for substantive cogency, representativeness, freedom from various forms of bias, and interscale independence. Both internal consistency and test-retest reliability coefficients are reported in the manual. The manual cites unique evidence for convergent and discriminant validity using peer ratings and hundreds of studies bearing on the validity and usefulness of the PRF in a very wide variety of settings.
