Adolescents With Attention-Deficit/Hyperactivity Disorder: Adverse Behaviors and Comorbidity.

Abstract

PURPOSE AND OBJECTIVE\nThere is growing evidence that adolescents with ADHD develop long-term impairments and adverse outcomes, yet less is known about their adverse behaviors. To quantify rates of mental health comorbidities in adolescents with ADHD and compare the risks of adverse behaviors among adolescents with and without ADHD.\n\n\nMETHODS\nWe performed a cohort analysis of 6,483 youth from the National Comorbidity Survey Adolescent Supplement (NCS-A), a nationally representative in-person structured diagnostic interview of adolescents aged 14-18\xa0years focusing on mental, emotional, and behavioral disorders.\n\n\nMAIN OUTCOMES\n(1) Percentages with comorbid anxiety, mood, disruptive behavior, and substance use disorders. (2) Strength of associations of ADHD with several adverse behaviors, including suicidal symptoms, aggression, behavior regulation, life events, education, and substance use. Odds ratios were adjusted for age, sex, and race.\n\n\nRESULTS\nAmong the sample of 6,483 adolescents, overall, 9.5% met the criteria for ADHD. Most (69.5%) of adolescents with ADHD had at least one comorbid mental health condition. As compared to adolescents without ADHD, those with ADHD were significantly more likely to have had a suicide attempt (aOR 2.9, 95% CI\xa0= 1.3-6.6) and to have had perpetrated physical aggression (aOR 2.3, 95% CI\xa0= 1.7-3.2). Adolescents with ADHD were also more likely to have been expelled from school or fired from a job (aOR 3.3, 95% CI\xa0= 1.7-6.5) and to have had problems related to drinking alcohol (95% CI\xa0= 1.2-2.9).\n\n\nCONCLUSIONS\nADHD in adolescents is a complicated disorder with elevated risks for a wide range of adverse behaviors.
