Association between MMPI-2-RF SUB items/scale and interview-reported substance abuse history among forensic psychiatric inpatients.

The purpose of this study was to examine associations between substance use disclosure during the clinical interview and on the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) Substance Abuse Scale (SUB) among forensic inpatients. Of the 223 archival reports reviewed that had MMPI-2-RF data, 69% of the MMPI-2-RF protocols were valid based on standard validity criteria, resulting in a final sample of 154 patients (98 men, 56 women). We found that patients who endorsed alcohol or marijuana use during the clinical interview often concurrently denied substance use on the MMPI-2-RF SUB scale (the opposite was found for prescription drug abuse).
