Abstract

This article describes the development of 21 brief content (BC) scales to supplement the existing scales of the Psychological Screening Inventory‐2 (PSI‐2), and three validity studies to support their use for both the PSI‐2 and the original PSI. The BC scales comprise groups of four or more items that are statistically homogeneous in content and are replicated across three data sets: PSI and PSI‐2 normative data and a PSI‐based group of forensic respondents. Concurrent validity was shown in correlations with the following: (a) the Minnesota Multiphasic Personality Inventory‐2 (MMPI‐2) basic clinical scales, Content scales, PSY‐5 scales, and Restructured Clinical (RC) scales; (b) family/friend observer ratings; and (c) therapist ratings in an outpatient substance abuse treatment program. Consistent with the purpose of the PSI/PSI‐2, the BC scales are intended to provide additional screening information and not a comprehensive representation of psychopathology. © 2010 Wiley Periodicals, Inc.
