Developmental Trajectories of Anxiety and Depression Symptoms from Early to Middle Childhood: a Population-Based Cohort Study in the Netherlands.

Developmental patterns of anxiety and depression symptoms in early childhood have previously been related to anxiety and mood disorders in middle childhood. In the current study, trajectories of anxiety and depression symptoms (1.5-10 years) were related to children's broader psychosocial and school-related functioning at 10 years.

Social and academic functioning in adolescents with anxiety disorders: A systematic review.
