As the newest generation of veterans returns home from their duties abroad, many face the individual and interpersonal aftereffects of duty-related traumatic experiences. Despite the established association between posttraumatic stress disorder (PTSD) and relationship problems, there is a lack of evidence-based conjoint treatments that target both PTSD and relationship distress. Cognitive-behavioral conjoint therapy (CBCT) for PTSD was developed to address this need. The authors summarize knowledge on the association between PTSD and relationship functioning, as well as recent research on veterans and their partners. Following an overview of CBCT for PTSD, the authors present a case study to illustrate the application of CBCT to an Operation Enduring and Iraqi Freedom couple.
