RELATIONSHIP FUNCTIONING AND PTSD SYMPTOMS POST DEPLOYMENT IN NATIONAL GUARD COUPLES

 Symptoms of post-traumatic stress disorder (PTSD) have been linked to different aspects of romantic relationship functioning. The literature demonstrates mixed results on which type of PTSD symptom is most impactful for successful romantic relationships. Many studies have examined this association both cross sectionally and longitudinally, and in many different populations. This association is of importance particularly for those highly exposed to trauma, such as those in the National Guard. The current study had two aims. The first was to examine the rates of change in Guard member’s (N = 175) PTSD and relationship functioning and their partners (N = 176) relationship functioning, across three waves following deployment. The second was to investigate the unique impact of each PTSD symptom cluster (re-experiencing, avoidance, and hyperarousal) occurring in the Guard Member on their own and their partner’s measures of relationship functioning. These aims were achieved through a secondary data analysis of a larger study that followed National Guard families from predeployment throughout reintegration. For the purposes of this analysis, Guard Member’s and their partners were assessed on relationship functioning measures 2 months, 8 months, and 13 months after deployment. The Guard member’s PTSD symptoms were assessed at the same time points. Multilevel modelling revealed that the Guard member’s PTSD symptoms and relationship functioning did not change significantly over time. Partner’s relationship functioning did not change either, with the exception of active engagement. Regression analysis revealed that Guard member’s PTSD avoidance symptoms are most strongly associated with both the Guard member and their partners ratings of relationship functioning. These findings identify an important area of possible intervention.
