Suicidality and non-suicidal self-injury among transgender populations: A systematic review

Abstract Introduction: Transgender individuals experience ongoing stigma, leading to a high mental health burden. This systematic review sought to identify risk and protective factors for suicidality and non-suicidal self-injury. Method: Three databases were searched and 52 articles selected. Risk and protective factors were categorized into discrimination, social support, comorbidities, medical transition status, and community and social policy factors. Result: Despite nearly all studies providing only cross-sectional or qualitative data, significant correlations were found between the categories of risk and protective factors and their respective outcomes. Conclusion: Future research should focus on prospective and longitudinal studies to further establish links of causality.
