Emotional Problems Suppress Disorder/Performance Associations in Adult ADHD Assessment

Issues related to Attention Deficit Hyperactivity Disorder (ADHD) are commonly assessed using a combination of indicators, including patient report and performance on cognitive tasks. The current study investigates the potential that emotional problems may suppress the relationship between objective continuous performance test (CPT) results and ADHD symptoms in a sample of 53 young adults referred to an outpatient clinic for cognitive evaluations, 26 of whom met diagnostic criteria for ADHD. Data indicate that emotional problems and continuous performance represent unique elements of adult ADHD, whether assessed via interview or self-report. Results also indicate that emotional problems do suppress CPT–ADHD relations, suggesting that failure to control for emotional problems may account, in part, for modest associations in the literature between CPT performance and other indicators of ADHD.
