title: MMPI taxonomies of child sexual and nonsexual offenders: a cross-validation and extension.
abstract: In a court clinic sample of 107 child sexual and nonsexual offenders, Minnesota Multiphasic Personality Inventory (MMPI) profiles did not differ as a function of arrests for sexual versus nonsexual offending. However, a three-group cluster-analytic solution was generated. Two of these clusters replicated those derived by Hall, Graham, and Shepherd (1991). The first cluster was unelevated, with Scales 4 and 9 as high points. The second cluster had MMPI Scales 4, 8, 2, and 7 as the highest scales. The third cluster was even more elevated than the other two clusters, characterized by extreme elevations on MMPI Scales F, 2, 4, 6, 7, and 8. The somewhat different results of this study versus previous studies (e.g., Hall et al., 1991) may be a function of the different populations sampled. The results provide evidence of within-group heterogeneity among sexual and nonsexual offenders that may be as important as between-group differences.
