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.
