Domestic violence is a significant public health issue. Prevalence rates for same-sex domestic violence vary because of methodological issues related to recruitment and definitions of sexual orientation. However, such prevalence rates are currently considered to be similar to slightly greater than other-sex prevalence rates. Research has identified differences between same-sex domestic violence and other-sex domestic violence, including internalized and externalized stressors associated with being a sexual minority that interact with domestic violence to create or exacerbate vulnerabilities, higher risk for complex trauma experiences, and difficulties accessing services. This review provides a critical review of the literature, focusing upon empirical findings regarding same-sex domestic violence.
