Use of the MMPI-A to detect substance abuse in a juvenile correctional setting.

In this study, we examined the ability of the MMPI-A (Butcher et al., 1992) to detect substance abuse problems in a juvenile correctional setting. Specifically, we evaluated the Alcohol/Drug Problem Acknowledgment scale (ACK; Weed, Butcher, & Williams, 1994), the Alcohol/Drug Problem Proneness scale (PRO; Weed et al., 1994), and the MacAndrew Alcoholism Scale-Revised (MAC-R; Butcher et al., 1992) in the prediction of substance abuse. In addition, the incremental validity of ACK in comparison to PRO was evaluated, as was the incremental validity of PRO in comparison to ACK. The sample consisted of 123 boys and girls from ajuvenile correctional facility in Northeastern Ohio. Results indicate that ACK and PRO, but not MAC-R, were related to interviewer ratings of substance abuse. Results point to the superiority of ACK over PRO in substance abuse identification.
