Longitudinal Data Show Discrimination Exposure Triples Suicidal Ideation Risk in LGBTQ+ Youth

The Trevor Project's ongoing Project SPARK cohort tracks participants via semiannual surveys since September 2023, capturing self-reported discrimination, conversion therapy threats, housing status, and mental health outcomes. Over two years, transgender and nonbinary youth reporting discrimination rose from 57% to 67%, conversion therapy exposure from 9% to 16%, and homelessness from 7% to 13%. Anxiety increased from 54% to 63% and depression from 43% to 51%, with suicidal ideation stable near 40%. These trends occurred against state-level policy shifts restricting gender-affirming care and school supports. The observational design cannot isolate causation from reverse causation or unmeasured confounders such as family rejection or co-occurring poverty. Prior cross-sectional surveys from the same organization and CDC Youth Risk Behavior data show similar gradients but lack repeated measures to assess temporal ordering. Intersectional patterns by race and disability status remain under-analyzed in the released aggregates. Sustained funding for longitudinal cohorts with validated clinical interviews and linkage to medical records is required to test whether policy interventions reduce incidence rates below current baselines.
