OBJECTIVE: The aim of this study was to clarify executive function weakness in attention-deficit/hyperactivity disorder (ADHD) during adolescence and determine the specificity of executive function weakness to ADHD symptom domains. METHOD: A total of 182 adolescents (105 boys), ages 13 to 17 years, completed a multistage diagnostic assessment; 85 were diagnosed with ADHD: 43 primarily Inattentive type (ADHD-PI) and 42 Combined type (ADHD-C). Participants completed the Stop, Trail Making, Wisconsin Card Sort, and Stroop tasks. RESULTS: The ADHD group exhibited impaired performance compared with the non-ADHD group on executive function measures (multivariate p < .05); there were no ADHD subtype differences. A composite executive function factor was significantly related to inattentive but not hyperactive-impulsive symptoms. CONCLUSIONS: Executive function weakness in adolescent ADHD is specifically related to symptoms of inattention-disorganization. Results are congruent with a dual-pathway model of ADHD cognitive mechanisms.
