Effect on disability outcomes of a depression relapse prevention program.

Area of Science:

• Psychiatry
• Clinical Psychology
• Health Services Research

Background:

• Depression relapse is a significant concern for patients treated with antidepressants.
• Identifying effective relapse prevention strategies is crucial for improving long-term patient outcomes.
• Patients at high risk for relapse require targeted interventions beyond standard pharmacotherapy.

Purpose of the Study:

• To evaluate the impact of a structured relapse prevention program on disability outcomes in high-risk depression patients.
• To compare the effectiveness of the intervention against usual care in reducing disability.
• To assess the 12-month disability outcomes using validated scales.

Main Methods:

• A randomized controlled trial involving 386 primary care patients treated for depression.
• Intervention group received systematic education, specialist visits, shared decision-making, and monitoring.
• Disability assessed using SF-36 and Sheehan Disability scales at multiple time points.

Main Results:

• Both groups showed improved functioning over 12 months.
• The SF-36 Social Function scale demonstrated a significant intervention effect.
• A nonsignificant trend for greater disability improvement was observed in the intervention group on the Sheehan Disability Scale.

Conclusions:

• The relapse prevention intervention had moderate effects on depressive symptoms, leading to modest and variable impacts on disability.
• High rates of maintenance pharmacotherapy in the usual care group may have influenced results.
• Further investigation is needed to understand the inconsistent disability outcomes and optimize relapse prevention strategies.
