Computer-Assisted Cognitive Behavior Therapy to Prevent Relapse Following Electroconvulsive Therapy

Area of Science:

• Psychiatry
• Neuroscience
• Digital Health

Background:

• Major depressive disorder (MDD) poses a significant public health challenge, often requiring intensive treatments like electroconvulsive therapy (ECT).
• Relapse remains a concern for patients achieving remission or response after acute ECT.
• Preventing relapse after ECT is crucial for sustained recovery and improved patient outcomes.

Purpose of the Study:

• To assess the feasibility of computer-assisted cognitive behavior therapy (CCBT) as a post-ECT intervention.
• To explore the potential efficacy of CCBT in preventing relapse in patients treated with ECT.
• To evaluate patient engagement and adherence to a CCBT course following ECT.

Main Methods:

• An open-label trial involving 15 participants with MDD who responded or remitted after ECT.
• Participants completed a 9-module CCBT course independently over 2 months.
• Depression severity and relapse were monitored for 6 months post-ECT.

Main Results:

• 15 participants enrolled, completing an average of 7.6 CCBT lessons (84%).
• 33% (5 out of 15) of participants relapsed within 6 months.
• No participants who initially achieved remission relapsed during the follow-up period.

Conclusions:

• CCBT is a feasible adjunctive therapy following ECT for MDD.
• Preliminary data suggest CCBT may aid in relapse prevention, particularly for those achieving remission.
• Larger, controlled studies are warranted to establish the definitive efficacy of CCBT post-ECT.
