Prevalence of co-occurring disorders among juveniles committed to detention centers.

The Practical Adolescent Diagnostic Interview (PADDI), a structured diagnostic interview designed to gather basic information about substance use disorders, mental health conditions, and related experiences, was used in routine evaluation of all adolescents committed to two juvenile detention centers. Anonymous data from 252 consecutively admitted adolescents were analyzed to assess the prevalence and severity of problem areas and to provide a preliminary exploration of interrelationships among those problems. Results demonstrated that a majority of adolescents manifested multiple problems.
