ObjectivesDigital mental health interventions are a promising therapeutic modality to provide psychological support to LGBTQIA+ (lesbian, gay, bisexual, trans, Queer, intersex, asexual, plus other gender, sexual, and romantic minority identities) people. The aim of this narrative review is to explore how the LGBTQIA+ community has been engaged in the design of digital mental health interventions, how content has been tailored to the LGBTQIA+ community, and features identified as important by LGBTQIA+ participants.MethodsA total of 33 studies were included in this review from a larger yield of 1933 identified from systematic searches of five databases (PsycINFO, PubMed, Scopus, CINAHAL, and Medline). Data were analyzed narratively and using content analysis.ResultsOnly half of the studies reported engaging the LGBTQIA+ community in intervention designs. Interventions have been tailored in a variety of ways to support LGBTQIA+ individuals—such as through affirming imagery, recruitment through LGBTQIA+ networks, and designing content to focus specifically on LGBTQIA+ issues. A range of features were identified as important for participants, namely how content was tailored to LGBTQIA+ experiences, providing connection to community, and links to other relevant LGBTQIA+ resources. While not a primary aim, results also showed that a wide range of digital modalities can significantly improve a range of mental health problems.ConclusionDigital interventions are an acceptable and effective form of therapeutic intervention, but future research needs to focus on meaningful engagement of community members to inform design and implementation.
