Abstract

The purpose of this study was to assess the differences between the MMPI-2 and the MMPI-RC scales in sensitivity to levels of psychopathology. Ninety-eight clients from forensic, disability and psychotherapy evaluations were evaluated on the MMPI-2 and RC scales and rated for personality organization (neurotic, borderline or psychotic) on the Psychodiagnostic Chart. The results over-all showed support that most of the MMPI-2 scales have more clinical sensitivity than the RC scales at all levels of psychopathology and particularly at the less pathological levels. K correction does not account for the elevation differences. Most of the RC scales add little to no incremental validity to the MMPI-2 Clinical scales except for RC 1, RC 2, and RC 9 and these may be used as supplemental scales.
