Neuropsychology, Vol 38(6), Sep 2024, 487-500; doi:10.1037/neu0000960Objective: Children with attention-deficit/hyperactivity disorder (ADHD) exhibit difficulties with organizational skills such as task planning, managing materials, and organizing activities that have downstream consequences on academic functioning. At the same time, deficits in working memory have been linked with both the organizational skills difficulties and academic underachievement and underperformance observed in children with ADHD and have been hypothesized to account for the link between organizational and academic functioning. However, the extent to which working memory and organizational skills independently versus jointly contribute to ADHD-related academic difficulties remains unclear. Method: The present study is the first to examine the unique and shared roles of working memory and organizational skills for explaining ADHD-related underachievement and underperformance in a clinically evaluated sample of 309 children with and without ADHD (Mage = 10.34, SD = 1.42; 123 girls; 69.6% White Not Hispanic or Latino). Results: Bias-corrected, bootstrapped latent path analyses revealed that working memory and organizational skills together accounted for 100% of the academic achievement (d = −1.09) and 80.6% of the academic performance (d = −0.58) difficulties exhibited by children with ADHD. Working memory (d = −0.95 to −0.26), organizational skills (d = −0.30 to −0.11), and shared variance across working memory and organizational skills (d = −0.13 to −0.06) each independently predicted ADHD-related difficulties in both academic achievement and performance outcomes. Conclusions: These findings are consistent with models suggesting that working memory has downstream consequences for functional impairments in ADHD, as well as evidence that organizational skills and working memory are each important predictors of ADHD-related academic functioning.
