Minority stress and mental health in European transgender and gender diverse people: A systematic review of quantitative studies.

The current study aimed at systematically reviewing evidence on the relationships between gender minority stress and mental health outcomes among European transgender and gender diverse (TGD) individuals. A systematic search was conducted in PsycINFO, PubMED, Scopus, and Google Scholar. It was based on Boolean operators to combine terms related to minority stress, TGD identities, and mental health. Thirty studies were identified as eligible. The results confirmed that gender minority stress factors are significantly related with mental health problems among European TGD individuals. Distal stressors were identified as strongly associated with poorer mental health, with gender-related discrimination emerging as the most documented risk factor. The significant role of proximal stressors was also highlighted, with some mediation analyses detecting an indirect effect on mental health. However, identity concealment appeared unrelated to mental health outcomes. Resilience-promoting factors buffering the impact of stressors were also identified, including self-esteem, pride, transitioning, and social support. Conversely, data on community connectedness as a source of resilience were inconclusive. The studies reviewed have several limitations, including lack of longitudinal designs, sampling bias, variability in measurement methods, and unaccounted ethnic variables. Research and clinical recommendations in this field are reported.
