Couple-based Intervention for Depression: An Effectiveness Study in the National Health Service in England

Area of Science:

• Psychology
• Clinical Psychology
• Mental Health Services Research

Background:

• Depression often affects couples, with high comorbidity of relationship distress and anxiety/depression in non-client partners.
• The Improving Access to Psychological Therapies (IAPT) program in England aims to increase access to evidence-based psychological treatments.
• Couple-based interventions are crucial for addressing depression within a relational context.

Purpose of the Study:

• To evaluate the effectiveness and service delivery of cognitive behavioral, couple-based treatment for depression (BCT-D) within London's IAPT services.
• To assess BCT-D recovery rates compared to general IAPT treatments for depression.
• To examine BCT-D effectiveness concerning relationship distress and the mental health status of the non-client partner.

Main Methods:

• Effectiveness study and service evaluation of BCT-D implemented in community clinics.
• Therapist training involved a 5-day workshop and 1 year of monthly group supervision.
• Outcome data collected from 63 couples where at least one partner had depression and received BCT-D.

Main Results:

• BCT-D demonstrated a 57% recovery rate for depression, exceeding the 41% rate for all IAPT depression treatments in London.
• Non-client partners with depression or anxiety also showed a significant 48% recovery rate with BCT-D.
• Treatment effectiveness was consistent regardless of relationship distress levels or the non-client partner's clinical status.

Conclusions:

• BCT-D is a promising, effective treatment for depression within routine clinical settings, successfully assisting both partners simultaneously.
• The findings support the integration of couple-based interventions into public mental health services like IAPT.
• BCT-D offers a valuable approach for couples experiencing depression and relationship distress.
