ADHD and Academic Success in University Students: The Important Role of Impaired Attention

Objective To improve on several methodological issues regarding current literature investigating the relationship between ADHD symptomatology and academic success in adults and examine the relative contributions of specific dimensions of ADHD symptomatology (i.e., inattention, hyperactivity, and impulsivity) to post-secondary academic success. Method A large sample of 3,688 post-secondary students were examined using a longitudinal design. The Conners' Adult ADHD Rating Scale (CAARS) was used to assess adult ADHD symptoms and academic success was assessed using students' official academic records (e.g., final GPAs and degree completion status). Results Students with greater inattention symptomatology at the start of their academic program showed consistently poorer long-term academic success (i.e., lower GPAs, higher dropout rates), regardless of gender. Conclusion Inattention symptoms are the primary driver of the relationship between ADHD symptomatology and academic underachievement in adults. Post-secondary education institutions should target and prioritize educational programming for inattention symptoms of ADHD in at-risk post-secondary students.
