Contributions of impulsivity and callousness in the assessment of adjudicated male adolescents: a prospective study.

This study examined whether delinquent adolescents with low scores on personality scales related to callousness and impulsivity would show less antisocial behavior and better psychosocial functioning compared to those elevated on 1 or both scales. A group of 162 White and African American male adolescents, recently adjudicated in a southern youth court system, were assessed at baseline and at 18-month follow-up. Dependent variables included measures of antisocial and prosocial behaviors, days detained in juvenile detention, and symptoms of psychopathology. As hypothesized, adolescents low on both callousness and impulsivity spent fewer days detained and reported less antisocial behavior and fewer symptoms of psychopathology compared to those high on I or both scales. Finally, African American participants were detained for more days, but did not report significantly more antisocial behaviors or symptoms of psychopathology compared to the White adolescents. The results suggest that being low on callousness and impulsivity may serve a protective role for future delinquent behavior for both African American and White adolescents.
