LGBT+ people’s suicide vulnerability in Czechia: Minority stress in a high structural stigma context

Abstract Background Suicide significantly impacts LGBT+ populations due to minority stress and stigma, yet targeted prevention is limited in Czechia. This study, first of its kind in Czechia, explores suicidal ideation and related risk factors among LGBT+ individuals in this context. Methods A cross-sectional online survey involved 1,778 Czech LGBT+ participants. Measures included suicidal ideation (SIDAS), minority stressors (harassment, internalized homonegativity), and interpersonal factors (loneliness, social support). Regression models identified key predictors. Results Transgender/gender diverse and bisexual/PAQ+ cisgender women reported higher suicidal ideation than cisgender gay men, lesbians, and bisexual/PAQ+ men. Loneliness and harassment positively predicted ideation; family and significant other support had protective effects. Combined factors explained 30% variance in ideation (pseudo R²=.300). Conclusions Loneliness, harassment, and weak social support significantly influence suicidal ideation among Czech LGBT+ individuals. Targeted mental health interventions and anti-discrimination policies are urgently needed.
