Longitudinal trajectories of depressive symptoms in adolescent students.

ABSTRACT:

Background

Longitudinal studies examining depressive symptom trajectories in adolescents remain limited, particularly in school-based populations. This study aimed to identify psychosocial risk and protective factors associated with depressive symptom trajectories in a cohort of Chinese adolescents.
