Abstract
Few studies have examined differential treatment response, rates of familial accommodation (FA), and executive functioning (EF) in youth with OCD vs. OCD + ADHD, particularly in a partial hospitalization program. The current study includes 138 youth diagnosed with OCD only and 102 youth diagnosed with OCD + ADHD for a total sample of 240 youth (and their families). Families and clinicians completed several measures assessing child and parent variables of interest. Findings of ANCOVA analyses suggest poorer treatment response and executive functioning in children with comorbid OCD + ADHD compared to their counterparts with OCD only. No significant differences emerged between groups in baseline levels of symptom severity, functional impairment, or familial accommodation. Given the high rate of comorbidity between OCD + ADHD, clinicians and researchers should be aware of the need to modify treatment approaches for children with comorbid OCD + ADHD and/or EF deficits.
