Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The objective of this study is to assess the burden and impact of ADHD impairment in the early morning and late afternoon/evening hours for adolescents and young adults. Functional impairments will focus on the currently identified areas of functional impairment in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5, American Psychiatric Association, 2013) - namely, social, academic, and occupational functioning. This is necessary for two reasons: (1) the current literature on ADHD impairment and functioning is concentrated within elementary school children; and (2) studies of intervention effectiveness are typically concentrated during the school day. This current state of the literature ignores the obvious - as ADHD is a chronic disorder, it needs to be addressed as children grow into adolescence and young adulthood, and it needs to be remediated at times outside of the school day such as in the morning and late afternoon/evening. Therefore, the specific areas assessed in the present study will relate to driving, school, work, and family functioning. These are important areas to study, as the research literature has typically focused on elementary school and school-day behavior in assessments of symptom presentation, impairment, and treatment outcome. As individuals with ADHD grow older, the entire day becomes relevant in determinations of functioning (e.g., workdays may begin in the very early morning or last into the evening/night), and productivity can be assessed across waking hours rather than just across the elementary school day. Once areas of functional impairment in these times of day are determined, for this age group, treatment candidates can aim to address these treatment targets.
