The authors conducted a meta-analysis of the literature on associations between trauma survivors' PTSD symptoms and the (a) relationship quality and (b) psychological distress of intimate partners. Results yielded a small combined effect size (r = -.24) for the association between PTSD and partners' perceived relationship quality. Gender and military status moderated this association with a larger effect size for female partners of male trauma survivors than for male partners of female trauma survivors and a larger effect size for military samples than for civilians. The effect size of the association between PTSD and partners' psychological distress was moderate in magnitude (r = .30). Analysis of hypothesized moderators indicated this association was stronger among military than civilian samples. The association was also stronger among samples of survivors who experienced traumatic events in the more distant past compared with those who experienced more recent events. Results support the systemic impact of one family member's PTSD symptoms and highlight areas for future research.
