Testing adaptations of cognitive-behavioral conjoint therapy for PTSD: A randomized controlled pilot study with veterans. Couple and Family Psychology: Research and Practice, 10(2), 71–86. https://doi.org/10.1037/cfp0000148https://hdl.handle.net/1805/27180Iraq and Afghanistan Veterans with posttraumatic stress disorder (PTSD) have well-documented relationship problems and many wish to include their intimate partners in treatment. This pilot study randomly assigned 46 couples (Veterans with clinician-administered PTSD scale confirmed PTSD diagnosis and their intimate partners) to one of two groups. The treatment group received a modified mindfulness-based version of cognitive-behavioral conjoint therapy for PTSD (CBCT; Monson & Fredman, 2012) that included all three phases of the mindfulness-based cognitive behavioral conjoint therapy (MB-CBCT). The control group received a modified version of CBCT that included communication skills training from Phases 1 and 2 of CBCT (CBCT-CS) without PTSD-specific content. Modified CBCT Phases 1 and 2 content was delivered to both groups during weekend retreats in multicouple group sessions. The postretreat protocol for MB-CBCT included nine individual couple sessions: a transition session following the retreat, and CBCT Phase 3. For CBCT-CS, two additional monthly multicouple group sessions reviewed communication skills. No statistically significant pre- to posttreatment differences were detected for primary outcomes between groups: Clinician-Administered PTSD Scale for Veterans (mean change difference, −1.4, 95% CI [−16.0 to 13.2]); Dyadic Adjustment Scale for Veterans (mean change difference, −1.0, 95% CI [−13.2 to 11.2]); and Dyadic Adjustment Scale for Partners (mean change difference, −0.4, 95% CI [−8.9 to 8.1]). However, within group pre- to posttreatment effect sizes were medium to large for both MB-CBCT and CBCT-CS on all three primary outcomes. Findings suggest that Veterans returning from recent conflicts and their partners may benefit from both modifications of CBCT.enCC0 1.0 Universal (CC0 1.0)couple therapyPTSDCBCTArticle
