Y-BOCS

The most widely used clinical assessment tool for measuring the severity of OCD symptoms. The Y-BOCS includes a symptom checklist that categorizes obsessions and compulsions by type, and a severity scale that rates the time occupied by symptoms, interference with functioning, distress, resistance effort, and degree of control. The Y-BOCS is used in clinical practice to establish baseline severity, track treatment progress, and guide treatment decisions. Research suggests that the standard checklist may not capture the full diversity and granularity of individual trigger experiences.
