Correlates of the MMPI–A Psychopathology Five (PSY–5) Facet Scales in an Adolescent Inpatient Sample

We explored the validity of the Psychopathology Five (PSY–5) facet scales of the adolescent version of the Minnesota Multiphasic Personality Inventory (MMPI–A; Butcher et al., 1992 Butcher, J., Williams, C. W., Graham, J., Archer, R., Tellegen, A.Ben-Porath, Y. 1992. Minnesota Multiphasic Personality Inventory–Adolescent (MMPI–A): Manual for administration, scoring and interpretation, Minneapolis: University of Minnesota Press. [Google Scholar]) in an adolescent inpatient psychiatric sample (N = 662) through a series of correlational analyses with self-report measures, therapist ratings, and chart review variables. Consistent with previous research with PSY–5 parent scales, externalizing symptoms were most clearly related to Hostility and Delinquent attitudes facet scales; internalizing symptoms were most clearly related to the presence of high Neuroticism facet scales and Low Drive/Expectations facet scales; and bizarre features and psychotic symptoms were most strongly related to both the Psychotic Experiences and Odd Mentations facet scales as well as the Low Drive/Expectations facet scales. These findings lend some support for the use of these facet scales as useful adjuncts to the PSY–5 parent scales.
