An update of the Couple Adaptation to Traumatic Stress Model: Systematic research synthesis of the association between secondary trauma survivor functioning and couple functioning.

Systemic theories addressing posttraumatic stress disorder (PTSD) in couples postulate associations between primary trauma survivor functioning, secondary trauma survivor functioning, and couple functioning. However, there is a lack of examination of the association between secondary trauma survivor functioning and couple functioning, which has clinical implications. Objectives of this study include informing clinicians of the evidence base for these associations and providing a synthesized review of research on PTSD in couples to inform future research. A systematic research synthesis screening 150 articles from three databases resulted in the inclusion of 15 quantitative articles to examine the quality of the available research addressing the association between secondary trauma survivor functioning and couple functioning. Correlation matrices in all studies and other partial evidence supported the current theory positing the relevance of secondary traumatic stress in interpersonal functioning for couples. Discussion includes the need for increased quality and diversity of systemic trauma research and treatment for couples.
