Background

Partners play an important role in a couple's life, and the whole family may face various challenges when meeting post-traumatic stress disorder (PTSD). This study aimed to explore the therapeutic effect of couples' therapies for PTSD.

Results

The couples' therapies showed an adherence rate (Proportion = 69%, 95%CI: 64% to 73%). Comparing with before couples' therapies, there were significant improvement in for patients (SMD = -0.79, 95%CI: -1.13 to -0.46) and for partners (SMD = -0.78, 95%CI: -1.05 to -0.52) after therapy, and there were significant improvement in intimate relationship functioning for patients (SMD = 0.27, 95%CI: 0.12 to 0.42) and partners (SMD = 0.38, 95%CI: 0.20 to 0.56), and in depression level for patients (SMD = -0.61, 95%CI: -0.82 to -0.40) and partners (SMD = -0.29, 95%CI: -0.50 to -0.07) after couples' therapies. Outcomes included comparisons with subgroup analysis which revealed that PTSD symptoms had better consequence for patients in age < 40 (SMD = -1.04, 95%CI: -1.93 to -0.16), male (SMD = -1.48, 95%CI: -1.95 to -1.01), and sessions ≥ 10 (SMD = -1.14, 95%CI: -1.53 to -0.74), trauma-focused (SMD = -1.17, 95%CI: -1.60 to -0.73), non-military personnel (SMD = -1.37, 95%CI: -1.94 to -0.79) and CBCT (SMD = -0.87, 95%CI: -1.24 to -0.49) had preferable outcomes for in PTSD symptoms.
