Abstract
The Personality Psychopathology Five (PSY-5; A. R. Harkness & J. L. McNulty, 1994) is a dimensional model of personality. Scales to measure the PSY-5 in adolescents were constructed from Minnesota Multiphasic Personality Inventory-Adolescents (MMPI-A) items. From the MMPI-2-based PSY-5 scales (A. R. Harkness, J. L. McNulty, & Y. S. Ben-Porath, 1995), 104 items are found in the MMPI-A booklet. Replicated rational selection (A. R. Harkness, J. L. McNulty, & Y. S. Ben-Porath, 1994) was used to identify additional items from questions unique to the MMPI-A. Preliminary scales were refined with internal psychometric analyses using the MMPI-A normative (N = 1,620; J. N. Butcher, C. L. Williams, J. R. Graham, R. P. Archer, A. Tellegen, Y. S. Ben-Porath, & B. Kaemmer, 1992) and clinical (N = 713; C. L. Williams & J. N. Butcher, 1989) samples. The median coefficient alpha for the 5 scales was.76 in both samples; the mean absolute scale intercorrelation was.32 in the normative sample and.30 in the clinical sample. Correlations with collateral data supported the construct validity of the scales.
