Aim: This meta-synthesis explores how gender roles and stereotypes affect IPV in LGBTQ+ relationships, based on the perspectives of those involved in the relationships. Methodology: A systematic review and qualitative meta-synthesis of peer-reviewed studies (2000–2025) was conducted using PubMed, PsycInfo, Medline, and HINARI. SPIDER guided keyword generation, and PRISMA was used in the article selection. Studies were quality assessed, and analyzed through inductive thematic analysis. Results: Four key themes emerged: (1) disbelief and systemic neglect, (2) victim blaming, (3) social and identity-based barriers to help-seeking, and (4) difficulties recognising IPV. Misgendering, outing threats, and stigma further limited service access and reinforced invisibility. Conclusions: Established gender norms and stereotypes have a negative effect on IPV recognition and reporting in LGBTQ+ communities. Broader IPV frameworks, inclusive training, and policy reform are essential to ensure all survivors are supported and validated.
