Use of the MMPI to identify subtypes of delinquent adolescents.

Assessed the utility of the MMPI to identify and distinguish among subtypes of delinquent adolescents (N = 50). Behavior ratings were used as the criterion of classification into three delinquent subtypes--conduct problem, anxious-withdrawn, and a group with neither of those features. Only the Hs scale differed significantly between the first two groups. Results were disappointing in that they failed to support a previous study that had found differences, but that had used less rigorous classification criteria.
