The proposed changes to the personality disorder section of the "Diagnostic and Statistical Manual of Mental Disorders" (5th ed.) places an increased focus on interpersonal impairment as one of the defining features of personality psychopathology.

The impact of measurement invariance and the provision for partial invariance in confirmatory factor analytic models on factor intercorrelations, latent mean differences, and estimates of relations with external variables is investigated for measures of two sets of widely assessed constructs: Big Five personality and the six Holland interests…

Reliability and construct validity of observer ratings on the Revised NEO Personality Inventory (NEO PI-R) were evaluated in a sample of 101 college students and the observations of 2 people who knew each student. Results document the strong internal consistency of each scale and a factor structure replicating previous findings. (SLD)

Confirmatory factor analysis was used to test the theoretical structure of the revised Personal Style Inventory (PSI) (C. Robins and others, 1994) with 869 nonclinical adults and 101 outpatients with depression. PSI items and subscales decomposed into factor structures that were fair to good representations of the theoretical model. (SLD)

The purpose of this study was to investigate convergent and discriminant validity of the five-factor model of adolescent personality in a school setting using three different raters (methods): self-ratings, peer ratings, and teacher ratings. The authors investigated validity through a multitrait-multimethod matrix and a confirmatory factor…
