Area of Science:

• Psychiatry and Behavioral Science
• Clinical Psychology
• Couple Therapy Research

Background:

• Posttraumatic stress disorder (PTSD) frequently co-occurs with intimate relationship challenges.
• Relationship factors significantly influence treatment outcomes for individuals with PTSD.

Purpose of the Study:

• To evaluate the efficacy of cognitive-behavioral conjoint therapy (CBCT) for PTSD compared to a wait-list control.
• To assess CBCT's impact on PTSD symptom severity and relationship satisfaction simultaneously.

Main Methods:

• A randomized controlled trial involving 40 heterosexual and same-sex couples where one partner had PTSD.
• Participants received either immediate 15-session CBCT for PTSD or were placed on a wait list.
• Outcomes including PTSD severity, comorbid symptoms, and relationship satisfaction were assessed by blinded evaluators at multiple time points and at a 3-month follow-up.

Main Results:

• Cognitive-behavioral conjoint therapy for PTSD led to significantly greater reductions in PTSD symptom severity compared to the wait-list condition.
• Patients receiving couple therapy reported significantly higher intimate relationship satisfaction than those in the wait-list group.
• Treatment benefits for PTSD symptoms and relationship satisfaction were sustained at the 3-month follow-up.

Conclusions:

• Cognitive-behavioral conjoint therapy for PTSD is an effective intervention for couples where one partner has PTSD.
• The therapy successfully decreases PTSD symptom severity and comorbid symptoms while enhancing relationship satisfaction.
• Couple-focused therapy offers a valuable approach for managing PTSD and its relational impact.
