The Personality Psychopathology Five (PSY-5): Constructs and MMPI-2 scales.

Abstract

The Personality Psychopathology Five (PSY-5; A. R. Harkness & J. L. McNulty, 1994) is a dimensional descriptive system for personality and its disorders. Replicated rational selection was used to generate Minnesota Multiphasic Personality Inventory-2 (MMPI-2; J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989)-based scales for the PSY-5. The scales are Aggressiveness, 18 items; Psychoticism, 25 items; Constraint, 29 items; Negative Emotionality/ Neuroticism, 33 items; and Positive Emotionality/Extraversion, 34 items. In three clinical samples with Ns of 328, 156, and 1,196; a college sample with an N of 2,928; and MMPI-2 normative samples with an N of 2,567, alphas ranged from.65 to.88. For 838 college students who had also completed Tellegen's (1982) Multidimensional Personality Questionnaire (MPQ), correlations between PSY-5 scales and corresponding MPQ superfactors were as follows: Constraint, r =.57, p < .01; Negative Emotionality/Neuroticism, r =.72, p <.01; and Positive Emotionality/Extraversion, r =.62, p <.0.1 PSY-5 Aggressiveness correlated r =.59, (p <.01) with MPQ Aggression. PSY-5 Psychoticism correlated r =.61 (p <.01) with MPQ Alienation
