Self-harm and suicide attempts among incarcerated lesbian, gay and bisexual people in Australia.

Abstract

Guided by minority stress theory, we explored the association between sexual identity, justice system involvement, self-harm and suicide attempts, among a cohort of incarcerated adults in Australia. A sample of 2698 adults incarcerated in Queensland and Western Australia were surveyed between 1 August 2008 and 12 August 2016 about their current psychological distress, mental health diagnoses, contact with mental health services, and lifetime and recent self-harm and suicide attempts. We used multivariable logistic regression to explore the relationship between sexual orientation, prior criminal justice system involvement, mental health and demographic factors. Five percent of the sample identified as gay, lesbian or bisexual, with 37% of lesbian, gay, bisexual and other same-sex attracted individuals reporting that they had self-harmed (vs 14% of heterosexual peers; χ2 = 52.4; p < 0.001) and 49% reporting a history of at least one suicide attempt (vs 23%; χ2 = 49.2; p < 0.001). Lesbian, gay, bisexual and other same-sex attracted people were 2.1 times (95% confidence interval: [1.4, 3.3]) and 1.8 times (95% confidence interval: [1.2, 2.8]) more likely to report a history of self-harm and suicide attempt, respectively, than non-lesbian, gay, bisexual and other same-sex attracted respondents. Intersectionality theory suggests that people who are navigating two or more marginalised identities often experience a compounding of internal and external stressors. Consistent with that theory, lesbian, gay, bisexual and other same-sex attracted people who experience incarceration may be at particularly high risk of self-harm and suicidal behaviour. Custodial settings should both improve cultural competency for frontline staff working with lesbian, gay, bisexual and other same-sex attracted individuals and improve access to mental health services during incarceration.
