To address the impact of combat‐related posttraumatic stress disorder (PTSD) on U.S. Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) veterans, the investigators developed a 12‐session manualized PTSD treatment for couples called structured approach therapy (SAT). A randomized controlled trial had shown that 29 OEF/OIF veterans with combat‐related PTSD who had participated in SAT showed significantly greater reductions in PTSD compared to 28 veterans receiving a 12‐session PTSD family education intervention (Sautter, Glynn, Cretu, Senturk, & Vaught, 2015). We conducted supplemental follow‐up and mediation analyses, which tested the hypothesis that changes in emotion functioning play a significant role in the decreases in PTSD symptoms primarily observed in veterans who had received SAT. Veterans assigned to the SAT condition showed significantly greater decreases than those assigned to PTSD family education in emotion regulation problems ( p < .001, Cohen's f 2 = .18) and fear of intense emotions ( p < .001, Cohen's f 2 = .152). Decreases in both emotion regulation problems (mediated effect:a b ̂= .36), and fear of intense emotions (mediated effect:a b ̂= .24) were found to be complementary mediators of reductions in PTSD symptoms greater with SAT. These findings suggest that SAT may aid veterans in improving their ability to regulate trauma‐related emotions.
