Background: A majority of youth with depression and related difficulties never access treatment. Barriers such as stigma, financial costs, and provider shortages contribute to this problem. Single session interventions (SSIs) have been found to benefit youth and help reduce depression symptoms. Since many SSIs are brief and can be accessed online, they may circumvent traditional barriers to accessing treatment, thus supporting wellbeing in individuals otherwise unable to access care. SSIs may be particularly beneficial for LGBTQ+ youth, for whom barriers to treatment are often exacerbated. There is a need to determine whether LGBTQ+ youth respond as positively to SSIs as non-LGBTQ+ youth, or if adaptations are needed prior to widespread dissemination. Methods: We investigated whether changes in helplessness, agency, and self-hate from before to after completing online SSIs differed as a function of LGBTQ+ identity in a sample of 258 youths (N=258, 81.4% female assigned sex, 60.5% LGBTQ+, 47.3% BIPOC). We also quantitatively and qualitatively compared intervention acceptability ratings and feedback across LGBTQ+ and non-LGBTQ+ youths. Results: Analyses revealed no significant differences between cisgender LGBQ+, trans and gender diverse, and cisgender heterosexual youths for any intervention outcomes. Likewise, no group differences emerged in intervention acceptability ratings or written program feedback. Limitations: Self-selection bias and underrepresentation of certain populations, such as American Indian and Alaskan Native youths, may limit generalizability of results.Conclusions: Results suggest that online mental health SSIs are equally acceptable and useful to LGBTQ+ and non-LGBTQ+ youth alike, even without culturally specific tailoring.
