| Abstract: | Administered the MMPI and elements of a neuropsychological assessment battery to 40 violent and 40 nonviolent adolescent males (M = 14.6 years). Multivariate analysis showed significant differences between groups on neuropsychological tests, but not on the MMPI. Discriminant function analysis indicated that the neuropsychological assessment had greater power to predict group membership of violent and nonviolent Ss than did the MMPI. The results are consistent with the hypothesis that organic impairment contributes to the impulse dyscontrol and associated violent behavior seen in some delinquent adolescents. |
