Informing a test taker about the presence of MMPI-2 validity scales has been shown to facilitate one's ability to dissimulate while simultaneously eluding test invalidation (Baer & Sekirnjak, 1997; Baer & Wetter, 1997; Baer, Wetter, & Berry, 1995). However, all studies examining this issue in clinical populations have used analogue designs, where individuals are coached to respond in a particular way. The current study expands on the existing literature by examining the impact of validity scale information (i.e., alternate instructions) on the MMPI-2 profiles of a clinical population naturally motivated to underreport: DWI offenders who have been court-ordered to seek treatment. An archival database containing MMPI-2 profiles for 216 therapy clients (court-ordered and non court-ordered) seeking services at an outpatient psychology clinic was used. Multivariate analyses of variance (MANOVA) followed up by discriminant function analyses (DFA) found support for the hypothesis that court-ordered clients are prone to underreporting. However, the hypothesis that validity scale information reduces the efficacy of validity scales in detecting defensive responding was not supported. Implications and future directions are discussed.
