Review: Longitudinal trajectories of child and adolescent depressive symptoms and their predictors – a systematic review and meta‐analysis

The review highlighted consistent evidence of subgroups of children and adolescents who differ in their depressive symptom development over time. The findings suggest preventative interventions should evaluate the longer term benefits of increasing membership in low and moderate trajectories, while also targeting reductions in high-risk subgroups. Considerable between-study method and measurement variation indicate the need for future trajectory studies to use standardized methods.
