^*All models adjusted for ACES ≥ 4, Age, Currently receiving mental health services, Family history of suicide, Family trust, History of suicide attempt, First generation student, International student, Pre-existing mental health condition, Prescription misuse, White Caucasian.

^**The 95% confidence interval for proportion of total effect mediated is based on 2.5% and 97.5% quantiles of bootstrapped estimates for proportion mediated from 1,000 imputed datasets.

^†Effect estimate is statistically significant at the alpha = 0.05 level.
