A comparison of adolescent inpatients with and without substance abuse using the Millon Adolescent Clinical Inventory

We compared clinical syndromes, expressed concerns, and personality styles of adolescent inpatients with substance use disorders (SUD; n=44) vs. without substance use disorders (non-SUD; n=61) using the Millon Adolescent Clinical Inventory. The two groups did not differ with regard to age, sex, ethnicity, functional severity, or the frequency of other major psychiatric disorders, and were drawn from the same overall sample population. SUD subjects showed significantly higher levels of delinquent predisposition and lower levels of anxiety. Consistent with these syndromal findings, we found that SUD subjects were characterized by higher levels of unruliness and social insensitivity and lower levels of submissiveness. Our findings suggest that, in severely disturbed adolescents who require psychiatric hospitalization, externalizing phenomena are closely associated with SUD. Our findings also suggest that internalizing problems also exist in SUD, although not at levels greater than that observed in non-SUD inpatients.Received Ph.D. in clinical psychology from the University of Pittsburgh.
