A brief motivational intervention for treatment-refusing OCD patients

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Therapy

Background:

• Exposure and Response Prevention (ERP) is the leading psychosocial treatment for Obsessive-Compulsive Disorder (OCD).
• Widespread adoption of ERP is hindered by low utilization rates among therapists and patient refusal.
• Patient refusal of ERP, estimated at 25%, presents a significant barrier to effective OCD treatment.

Purpose of the Study:

• To evaluate a brief, 4-session readiness intervention (RI) designed to reduce ERP refusal in OCD patients.
• To assess the impact of RI on patient willingness to commence ERP therapy.
• To examine the efficacy and dropout rates of ERP following RI.

Main Methods:

• A randomized controlled trial involving 12 OCD patients who had initially refused ERP.
• Participants were assigned to either the readiness intervention (RI) or a wait-list (WL) control group.
• Outcomes measured included agreement to start ERP and changes in OCD symptom severity.

Main Results:

• 86% of participants in the RI group agreed to start ERP, compared to 20% in the WL group.
• ERP initiated after RI led to OCD symptom reduction comparable to non-refusing patients.
• ERP following RI exhibited a high dropout rate of 50%.

Conclusions:

• A brief readiness intervention can effectively increase acceptance of ERP for OCD.
• Despite improved acceptance, high dropout rates post-RI warrant further investigation and intervention.
• Future research should focus on strategies to mitigate dropout and enhance long-term adherence to ERP.
