Personality characteristics of a community sample of adolescents with conduct disorders.

The Millon Adolescent Personality Inventory (MAPI) was used to compare the personality styles, expressed concerns, and behavioral correlates of a community sample of conduct-disordered (n = 13) and non-conduct-disordered (n = 137) adolescents. Structured interviews with adolescents and parents were used to classify subjects using DSM-III criteria. Significant differences were found between groups. Conduct-disordered youth reported being very critical, harsh, and not respectful of others. They tended to seek out the unpredictable and to be moody and pessimistic. They expressed a lack of confidence in school performance and dissatisfaction with family life. These results support the usefulness of self-report measurements with troubled adolescents in general, and the validity of the MAPI in particular. Implications for diagnosis and treatment are discussed.
