CASC: Negotiate first ERP session for contamination OCD
Candidate instructions
You are the psychiatry registrar. Priya, 31, has contamination OCD on sertraline 150 mg oral daily with partial benefit. She washes after any outdoor contact and her partner answers "are my hands clean?" many times daily. She is anxious about "making OCD worse" with exposure. In 10 minutes:[13]
- Explain ERP rationale in plain collaborative language.
- Negotiate one concrete first exposure with a clear response-prevention rule.
- Elicit predicted outcome (expectancy) and how you will review learning.
- Address partner accommodation without shaming.
- Set between-session homework and a brief risk/distress plan.
- Avoid becoming a reassurance ritual yourself.
