Description: Development of the Personality Research Form (PRF) was guided by the belief that more rigorous and valid assessment of personality characteristics could be achieved through the application of modern principles of personality and test theory. The goals established for the PRF were to develop an item pool and a set of personality scales relevant to normal human functioning in a wide variety of situations.
Scoring: There are 15 scores, which include: achievement, affiliation, aggression, autonomy, dominance, endurance, exhibition, harm avoidance, impulsivity, nurturance, order, play, social recognition, understanding, and infrequency.
Reliability: The odd-even reliabilities, adjusted using the Spearman-Brown correction, were calculated from the responses of 192 subjects. The reliability estimates for the personality scales ranged from .48 to .90, with a median reliability of about .78. The reliabilities of the Desirability (validity) Scale ranged from .59 to .66, and those of the Infrequency (validity) Scale ranged from .33 to .57. Test-retest reliability estimates ranged from .57 to .85, with a median of .77.
Validity: The PRF manual contains nine tables reporting correlations between scales on various forms of the PRF and scales on other tests. Reported are the relationships between the PRF-AA and the CPI and Strong Vocational Interest Blank (SVIB), the PRF-A and the Allport Vernon Lindzey Study of Values (SOV), and the PRF-E and the JPI, Jackson Vocational Interest Survey (JVIS), Bentler Psychological Inventory (BPI), Bentler Interactive Psychological Inventory (BIPI), and Cattell’s High School Personality Questionnaire (HSPQ). In general, the PRF scales have higher correlations with scales from the other instruments measuring the same or a similar construct (e.g., dominance-leadership) than with scales measuring different or antithetical constructs.
Norms: The normative sample consisted of 1,029 male and 1,002 female college students selected to represent a stratified random sample by regions of the United States.
Suggested Uses: The PRF is recommended for use in personality research and for measuring normal personality traits in settings such as schools, colleges, clinics, guidance centers, business, and industry.
