Abstract

While Attention-deficit/hyperactivity disorder (ADHD) remains one of the most common psychological disorders diagnosed, current understanding of the disorders expression and factors contributing to impairment in early adulthood remains limited. In an effort to better understand current issues with ADHD assessment and treatment in emerging adults, this study aimed to examine relationships between symptoms, executive function (EF), sleep, and impairment. Overall results of this study indicate that together, ADHD symptoms, EF, and sleep account for a significant proportion of variance in impairment. Additionally, results indicate that EF moderates the relationship between ADHD symptoms and impairment, and that sleep may be a protective factor for adults. Specifically, this study found that when compared to individuals reporting more sleep problems, the effect of ADHD symptoms and EF on impairment was much weaker among individuals reporting fewer sleep problems. Understanding the relationship between ADHD symptoms, EF, and sleep is critically important in better understanding adult ADHD and in informing assessment and treatment strategies to more effectively reduce impairment.
