Marriage Equality Laws and Youth Mental Health

Since the landmark ruling in Goodridge v. Department of Public Health in 2004, the legalization of same-sex marriage (SSM) has proliferated throughout the United States via either legislative action or court order. Advocates of SSM laws argue that marriage equality will generate important health benefits not only for adult same-sex couples but also for lesbian, gay, bisexual, and questioning (LGBQ) youths. Using data from the state Youth Risk Behavior Survey for the period 1999–2017, we explore the relationship between marriage equality and suicidal behaviors among LGBQ-identifying youths. We find little evidence that SSM laws have reduced suicide attempts among teen sexual minorities, nor have they decreased the likelihood of suicide planning, suicidal ideation, or depression. Instead, we find some evidence that SSM legalization via judicial mandate is associated with worse mental health for these youths.
