What it measures
The gold-standard measure of OCD symptom severity in clinical trials, assessing time spent, interference, distress, resistance, and control for both obsessions and compulsions. The self-report version (Y-BOCS-SR) closely mirrors the clinician-administered version and is widely used as a primary outcome in OCD RCTs.
