Using electronically delivered therapy and brain imaging to understand OCD pathology: A pilot feasibility study

Area of Science:

• Neuroscience
• Psychiatry
• Digital Health

Background:

• Obsessive-compulsive disorder (OCD) presents challenges in treatment accessibility and scalability.
• Current understanding of OCD's neural pathology is limited, hindering novel treatment development.
• Electronic cognitive behavioral therapy (e-CBT) offers a scalable alternative to traditional in-person therapy.

Purpose of the Study:

• To evaluate the feasibility and effectiveness of an e-CBT program for OCD.
• To investigate the impact of e-CBT on cortical activation during symptom provocation.
• To hypothesize that e-CBT can attenuate abnormal brain activations in OCD patients.

Main Methods:

• A 16-week e-CBT program was administered online to OCD patients.
• Treatment efficacy was assessed using behavioral questionnaires and neuroimaging (resting state and task-based).
• Cortical activation levels were measured before and after the e-CBT intervention.

Main Results:

• Significant improvements were observed in OCD symptom severity and daily functioning (p < 0.05).
• No statistically significant changes in quality of life or cortical activation were detected.
• Participants reported positive qualitative feedback regarding e-CBT's accessibility and content.

Conclusions:

• e-CBT is a feasible and effective intervention for improving OCD symptoms and functioning.
• Further research is needed to explore e-CBT's effects on neural mechanisms compared to in-person therapy.
• Understanding OCD's neural underpinnings can guide the development of future innovative treatments.
