WAIS-R and MMPI profiles of men who have sexually assaulted children: evidence of limited utility.

Wechsler Adult Intelligence Scale-Revised (WAIS-R) data were compiled on 101 male sexual offenders of children, and Minnesota Multiphasic Personality Inventory (MMPI) profiles were compiled for a subsample of 81 of these subjects in a replication and extension of the Hall, Maiuro, Vitaliano, and Proctor (1986) MMPI study. The MMPI profiles were heterogeneous and had multiple elevations. No significant relationships between the WAIS-R Full Scale IQ, WAIS-R Performance IQ Minus Verbal IQ Index, or the MMPI scales, and offense characteristics were obtained. These results support the hypothesis of Hall et al. (1986) that psychometric instruments may be of limited utility in characterizing or differentiating among sexual offenders on the basis of criminological variables.
