Background: Trans, gender diverse and non-binary (TGDNB) adults experience significant health disparities relative to their cisgender peers. While social support is a known health-protective factor within the general population, no systematic reviews of TGDNB experiences of social support exist. Aim: To systematically review prior research of social support for TGDNB adults. We sought to assess the defining characteristics of the research, the participants and the research findings, mapping emerging trends across disciplines. Methods: Six electronic databases (PubMed, MEDLINE, CINAHL, Web of Science, LGBT Life and PsycNet) were searched for literature pertaining to TGDNB adults, social support, and health or well-being published in the past decade. Results: The findings illustrate a predominance of USA-based quantitative research that measures social support of friends, family and a singular intimate partner. The majority of participants were white, binary-identified transgender women and TGDNB people living in metropolitan settings. Social support was commonly reported as a protective factor, with TGDNB peer support the most frequently reported correlate of health and well-being for TGDNB adults. Discussion: The results suggest standardized inventories do not capture the emic nature of social support for TGDNB adults. A key opportunity lies in an inductive, hypothesis-forming approach to the study of what is socially supportive for TGDNB adults. In turn, this knowledge will enable the appropriate measurement, implementation and interpretation of social support studies.
