Effects of coping-oriented couples therapy on depression: a randomized clinical trial

Area of Science:

• Psychology
• Clinical Psychology
• Psychotherapy Research

Background:

• Depression significantly impacts individuals and relationships.
• Established therapies like CBT and IPT are effective but may not address relational dynamics comprehensively.
• Couples therapy approaches offer a potential avenue for enhancing depression treatment outcomes.

Purpose of the Study:

• To compare the effectiveness of Coping-Oriented Couples Therapy (COCT) with Cognitive-Behavioral Therapy (CBT) and Interpersonal Psychotherapy (IPT) for treating depression.
• To evaluate the impact of these therapies on depressive symptomatology, recovery, and relapse rates.
• To assess the effects of each treatment on relationship quality, including satisfaction and dyadic coping.

Main Methods:

• A randomized controlled trial involving 60 couples with one clinically depressed partner.
• Utilized pre- and posttest questionnaires and follow-up assessments over 1.5 years.
• Measured depressive symptoms using the Beck Depression Inventory and Hamilton Rating Scale for Depression.

Main Results:

• COCT demonstrated comparable effectiveness to CBT and IPT in reducing depressive symptoms.
• No significant differences were found in self-reported relationship satisfaction or dyadic coping across the three treatment groups.
• COCT uniquely led to significant improvements in partners' expressed emotion compared to CBT and IPT.

Conclusions:

• COCT is a viable and effective treatment option for depression, offering similar outcomes to established therapies.
• While not superior in improving relationship satisfaction or dyadic coping, COCT positively impacts expressed emotion within couples.
• These findings support the integration of relational dynamics into depression treatment through therapies like COCT.
