Short-form Analysis of the Restructured Clinical Scales and PSY-5 Scales of the MMPI-2

Abstract

The Restructured Clinical (RC) Scales and Personality Psychopathology Five (PSY-5) Scales of the MMPI-2 are becoming more popular for interpretation of standard MMPI-2 profiles. These new scales were developed using all 567 questions of the MMPI-2, making it necessary for the patient to complete all items for interpretation of these scales. This study generate estimations of the RC and PSY-5 scales with protocols in which only 370 questions were completed. Equations were created with over 1000 protocols and then cross-validated with a different set of protocols. The results showed moderate utility of the RC and PSY-5 scales with only 370-items completed. The following provides tables which can be used in situations when only the first 370-items are completed, but additional interpretation with RC and PSY-5 scales is still desired.
