The MMPI and recidivism.

Compared MMPIs of 80 recidivists and 68 parole successes from a state training school by analyzing mean scale scores, elevations, code types, and mean ranks of the clinical scales. No important differences were identified. Conclusions are (1) the MMPI used alone is not useful in identifying recidivists in relatively homogeneous delinquent populations, (2) its use should be restricted to the exploration of small differences between groups, and (3) the combined use of historical information and the MMPI to identify recidivists needs study.
