Which tools are commonly used to track OCD progress during ERP?

• A. Beck Depression Inventory.
• B. Hamilton Anxiety Rating Scale.
• C. Y-BOCS or symptom diaries.
• D. Global Assessment of Functioning.

Answer: (C)

Tracking OCD progress during ERP relies on measures that directly capture obsessions and compulsions and how they change with treatment. The Yale-Brown Obsessive Compulsive Scale (Y-BOCS) is the gold-standard semi-structured interview for OCD severity, assessing both the frequency and intensity of obsessions and compulsions and their interference in daily life; it’s particularly sensitive to clinically meaningful change over the course of ERP. Symptom diaries add a daily, real-time record of urges, rituals, and distress, giving granular data that helps track progress between sessions and adjust exposure tasks. In contrast, the Beck Depression Inventory targets depressive symptoms, the Hamilton Anxiety Rating Scale measures general anxiety rather than OCD-specific symptoms, and the Global Assessment of Functioning provides a broad view of functioning, not precise OCD severity or change. Together, the Y-BOCS and symptom diaries best capture OCD progress during ERP.
