Commentary* by Dr. Margaret Weiss: If specific symptom domains are associated with specific domains of impairment this would alert clinicians to those difficulties and possibly help us to understand the mechanisms by which symptoms drive impairment.

ABSTRACT

Objective: The purpose of this study was to explore the unique relationships between specific attention-deficit hyperactivity disorder (ADHD) symptoms and functional impairment in school-age children using parent and teacher ratings.

Methods: Parents and teachers rated ADHD symptoms and comorbidities (internalizing and oppositional behaviors) as well as impairments (academic, relationship, and classroom behavior) for 8689 children using the Vanderbilt ADHD Diagnostic Rating Scales. Stepwise regression was used to determine which of the 18 ADHD symptom items were most associated with specific domains of impairment with relevant demographic and clinical characteristics used as covariates (e.g., sex, comorbidities, medication status, and age).

Results: « Careless mistakes » and « avoids tasks » significantly predicted academic impairment across content areas and across parent- and teacher-rating models. ADHD symptoms accounted for limited variance in impairment in the family and peer relationship domains or in organized activities when oppositional symptoms were entered as a covariate. Regarding teacher-rated classroom behavior, the strongest predictor of impairment was « talks too much. »

Conclusion: The findings indicate that the symptoms that were most predictive of impairment varied by domain of impairment.
