Medical Problems among Adolescents in U.S. Mental Health Services: Relationship to Functional Impairment

This study provides information about the extent of comorbidity between medical and behavioral problems among adolescents in mental health services, describes the clinical and sociodemographic characteristics of adolescents with both problems, and discusses the consequences or comorbidity for service delivery. Nationally representative mental health service use data for adolescents (age 12-17) in inpatient, outpatient, and residential mental health service settings (weighted N=296,755) were used. Close to one fifth (18.9%) of the adolescents had a medical problem, and adolescents with anxiety and pervasive developmental disorders had the highest rates of medical problems. In multivariate logistic regressions, having a medical problem significantly increased the odds of serious functional impairment; having a secondary or dual psychiatric diagnosis was only significant in interaction with a medical problem. The results underscore the need for adolescent behavioral health research and practice to attend to multiple influences on functioning.
