Background While prior research has documented intimate partner violence (IPV) and family of origin violence (FOV) experienced by LGBTQ communities at rates at least comparable to heterosexual and/or cisgender populations, little knowledge exists of how this experience occurs within intersections of these communities and who is most at risk. Methods This study utilised data from a from a large nationwide Australian survey of the health and wellbeing of 6835 LGBTQ adults aged 18 + years. Multivariable logistic regression analyses were conducted to identify individual factors associated with reporting ever having experienced FOV or IPV. Results In total, 2675 (43.18%) participants reported ever experiencing FOV and 3716 (60.7%) reported ever experiencing IPV. Non-binary people, cisgender women, and trans men were most likely to have experienced FOV. Non-binary people and cisgender women were most likely to experience IPV. Participants aged 55 + years (compared to 18–24 years) were less likely to have experienced FOV, while the likelihood of experiencing IPV increased with age. Education was associated with both FOV and IPV (highest among the non-university tertiary educated). Having a moderate or severe disability and ever experiencing homelessness were associated with a greater likelihood of experiencing FOV and IPV. Recent experiences of suicidal ideation, suicide attempt and high/very high psychological distress were associated with experiences of FOV and IPV. Conclusions This new knowledge regarding the factors that identify LGBTQ people at greater risk of family or intimate partner violence can ensure the tailoring of family violence practice and policy to those most in need.
