Objective: To evaluate the prevalence, demographic and clinical correlates, and specificity of classes of psychotropic medications indicated for mental disorders. Design: Cross-sectional survey. Setting: Direct household interviews of combined household and school samples representative of the general population of adolescents in the United States. Participants: Ten thousand one hundred twenty-three adolescents aged 13 to 18 years who participated in the National Comorbidity Survey Adolescent Supplement. Main Exposures: Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) mental disorders and neurodevelopmental disorders. Outcome Measure: Psychotropic medication use in the past 12 months. Results: Among youth with any DSM-IV mental disorder, 14.2% reported that they had been treated with a psychotropic medication in the past 12 months. Strong associations emerged between specific disorders and classes of medications with evidence for efficacy. Antidepressants were most frequently used among those with primary mood disorders (14.1%); stimulant use was most common among those with attention-deficit/hyperactivity disorder (20.4%); and antipsychotic use was infrequent and mostly seen among those with serious developmental disorders. Less than 2.5% of adolescents without a 12-month mental disorder had been prescribed psychotropic medications, and most had evidence of psychological distress or impairment reflected in a previous mental disorder, subthreshold condition, or developmental disorder. Appropriate medication use was significantly more frequent among those in treatment in the mental health specialty sector than general medicine or other settings. Conclusions: These findings challenge recent concerns over widespread overmedication and misuse of psychotropic medications in US youth. In fact, these data highlight the need for greater recognition and appropriate treatment of youth with mental health disorders. © 2013 American Medical Association.

Objective: Prolonged fatigue in adolescents has a major impact on social functioning and school attendance. In adults, prolonged fatigue substantially overlaps with mood and anxiety disorders. Extending the data to adolescents, the authors studied the prevalence and correlates of fatigue in a representative U.S. sample. Method: The participants were 10,123 adolescents ages 13-18 years from the National Comorbidity Survey Adolescent Supplement. They were interviewed about prolonged fatigue, defined as extreme fatigue with at least one associated symptom (pains, dizziness, headache, sleep disturbance, inability to relax, irritability) that does not resolve by resting or relaxing and lasting at least 3 months. Results: The prevalence of prolonged fatigue was 3.0% (SE=0.3), with 1.4% (SE=0.2) for prolonged fatigue only and 1.6% (SE=0.2) for prolonged fatigue concomitant with a depressive or anxiety disorder. Nearly 60% of the adolescents with prolonged fatigue only had severe or very severe disability, and their rates of poor physical and mental health were comparable to those of adolescents with mood or anxiety disorders only. Adolescents with prolonged fatigue and comorbid mood or anxiety disorders had significantly greater disability, poorer mental health, and more health service use than those with either condition alone. Conclusions: These findings suggest that prolonged fatigue is associated with disability and is an important clinical entity independent of mood and anxiety disorders in adolescents. Persistent fatigue with a comorbid mood or anxiety state is related to even more functional impairment, suggesting that prolonged fatigue may reflect greater severity of mood and anxiety disorders in adolescents.
