Does Family Accommodation Predict Outcome of Concentrated Exposure and Response Prevention for Adolescents?

Findings suggest that increased levels of family accommodation are associated with a poorer treatment outcome in obsessive-compulsive disorder (OCD). A concentrated treatment format, the Bergen 4-day treatment (B4DT), has previously demonstrated promising results in the treatment of adolescents with OCD. The present paper examined changes in family accommodation and investigated whether family accommodation predicted outcome, in a sample of 63 adolescents (age range 11-18) participating in the B4DT. There were significant reductions on CY-BOCS and FAS from pre- to post-treatment and from pre-treatment to follow-up (p < 0.001), with large within-group effect sizes on both measures. Pre-treatment levels of symptom severity or family accommodation was not found to predict outcome at post-treatment or at follow-up. Less OCD-related functional impairment at pre-treatment predicted a better outcome at both post-treatment and follow-up. The findings suggest that the B4DT significantly reduces OCD-symptoms regardless of pre-treatment levels of family accommodation or OCD severity.
