Validation of an interview-only version of the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) in treatment-seeking youth with obsessive-compulsive disorder

Research output: Contribution to journalArticle


There is a growing body of evidence suggesting that individuals with obsessive-compulsive disorder (OCD) may be sub-typed along different symptom dimensions. These dimensions may help explain responsiveness to current treatments. The Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) is a validated instrument involving a self-report screening tool followed by a structured interview in which the presence/absence and severity of OCD symptom dimensions are assessed and rated. The present study investigated the validity of a briefer, interview-only version of the DY-BOCS modified for use in routine care. Clinically-referred children and adolescents (N=119) with OCD were administered the DY-BOCS along with other measures of OCD, anxiety, depression, and overall functioning and a subset (N=100) were reassessed on average 14 months after initial assessment. This briefer, interview-only version of the DY-BOCS demonstrated high levels of internal consistency and correlated in the moderate to strong range with alternative measures of OCD severity and OCD symptom dimensions. Change scores on the DY-BOCS from baseline to follow-up were significantly correlated with change scores on the alternative measures of OCD and clinician-rated improvement, suggesting that this brief version of the DY-BOCS is valid and sensitive to the effects of treatment for OCD delivered in routine clinical care.
