Which statement correctly distinguishes ERP from flooding in OCD treatment?

• A. ERP uses gradual exposure with ritual prevention; flooding involves intense, sustained exposure.
• B. ERP is always longer than flooding; flooding uses gradual exposure.
• C. ERP is a pharmacological approach; flooding is behavioral.
• D. ERP targets cognitive distortions; flooding targets motor symptoms.

Answer: (A)

The key idea here is how exposure therapies differ in delivering exposure for OCD. ERP uses gradual, structured exposure to feared situations while simultaneously preventing the ritual or compulsion that normally follows. This combination lets anxiety rise and fall in a controlled way and, over time, the person learns that the feared outcome is unlikely and that they can tolerate the distress without performing rituals. The emphasis is on slowly approaching the feared stimulus and stopping the compulsive response, typically following a planned hierarchy and progressing step by step.

Flooding, on the other hand, involves exposing the person to a highly feared situation or stimulus for a prolonged period without any gradual buildup or avoidance. It’s intense and sustained exposure designed to provoke a strong anxiety response quickly, with the expectation that anxiety will habituate after the exposure ends. It bypasses the gradual stepping-stone approach used in ERP.

So the statement captures the essential distinction: ERP uses gradual exposure with ritual prevention, while flooding uses intense, sustained exposure. It’s also worth noting that ERP is a behavioral treatment (not pharmacological) and focuses on reducing ritualistic and avoidance behaviors rather than aiming at cognitive distortions or motor symptoms specifically.
