This systematic review focuses on dyadic relationships, and seeks to answer the following questions: 1) How do traumatic life events impact survivors and partners in dyadic relationships? 2) Is couple counseling an effective treatment for mental health or relationship issues when one or both partners have experienced trauma? The review contains ten articles. Although there is some overlap, six articles focus primarily on trauma outcomes in dyadic relationships and address the first research question. Five articles address the second question, and center around the treatment of trauma. Included are a mixture of qualitative and quantitative research. One study was a randomized control trial (RCT), one was quasi-experimental (pre- and post-treatment data collection), two utilized in-depth interviews and thematic analysis, and one article was a collection of vignettes outlining treatment. The remainder were correlational.
