Abstract

The number of college students with Attention-Deficit/Hyperactivity Disorder (ADHD) has been increasing over the last years. ADHD can co-occur with other mental health disorders, such as depression, which can impair emerging adults’ functioning. Executive functions, including working memory, inhibition, and sustained attention, mediate the association between ADHD symptoms and functional impairment. However, there is a lack of research on how depressive symptoms influence these relations. The purpose of this study was to examine whether EF mediates the relationship between ADHD symptoms and functional impairment and whether depressive symptoms moderate this association. The author hypothesized that EF would mediate the relation between ADHD and functional impairment, and depressive symptoms would serve as a moderator, specifically between EF and functional impairment. The results supported the hypothesis, with EF mediating the relation between ADHD symptoms severity and functional impairment and depressive symptoms moderating the relation between EF and functional impairment.
