title: An exploration of the impact of invalid MMPI-2 protocols on collateral self-report measure scores.
abstract: Although a number of studies have examined the impact of invalid MMPI-2 (Butcher et al., 2001) response styles on MMPI-2 scale scores, limited research has specifically explored the effects that such response styles might have on conjointly administered collateral self-report measures. This study explored the potential impact of 2 invalidating response styles detected by the Validity scales of the MMPI-2, overreporting and underreporting, on scores of collateral self-report measures administered conjointly with the MMPI-2. The final group of participants included in analyses was 1,112 college students from a Midwestern university who completed all measures as part of a larger study. Results of t-test analyses suggested that if either over- or underreporting was indicated by the MMPI-2 Validity scales, the scores of most conjointly administered collateral measures were also significantly impacted. Overall, it appeared that test-takers who were identified as either over- or underreporting relied on such a response style across measures. Limitations and suggestions for future study are discussed.
