INTRODUCTION: Transgender and non-binary people use more alcohol and report a greater need for help to reduce their consumption than their cisgender counterparts. They experience anticipated and enacted discrimination when seeking alcohol reduction healthcare. This study aimed to identify any alcohol reduction interventions for trans and non-binary people. METHODS: A systematic scoping review was completed according to PRISMA-ScR guidelines. Following an extensive search across five databases, two independent reviewers carried out abstract screening, full-text screening, data extraction and quality assessment. Findings were synthesised narratively. RESULTS: The search generated 1399 unique records. Ten texts were reviewed in full, and the final sample comprised six studies of moderate quality. Included records all reported adaptations of various psychosocial interventions including individual therapies, group therapy, a trans-affirmative clinical environment, and a specialist inpatient rehabilitation service. Four interventions resulted in alcohol reduction with modest effect size. However, the change in alcohol consumption was not statistically significant in two studies. Trans women were disproportionately investigated through the lens of HIV risk reduction. CONCLUSION: Interventions developed for one population cannot be presumed effective in another, particularly those as heterogeneous as trans and non-binary communities. There is some suggestion that psychosocial interventions adapted for the needs of the trans community are effective in achieving alcohol reduction. However, it is unclear how these will fare with trans men and non-binary people and specialist interventions may be needed.
