aOR: adjusted odds ratio; CI: confidence interval; NS: not significant.
Comparison group: no confidant
Comparison group: non-parental confidant
Comparison group: non-peer confidant
Note: All models adjusted for age, gender, past-year major depressive episode, and survey year. Sample sizes for models investigating effect moderation by relationship with confidant vary due to exclusion of adolescents reporting no confidant. Cross-product terms noted where significant; non-significant cross-product terms excluded.
