Unadjusted model: predicting NSSI from stressful life events with depressive symptoms at one-year follow-up being the mediator. Adjusted model: unadjusted model+controlling for covariates in Table 1 except for stressful life events+NSSI at baseline. ,, and. CI: confidence interval; NSSI: non-suicidal self-injury.
