Note: N = 618.

Puberty = Prepubertal status (0) or pospubertal status (1). 5-HTTLPR = functional variation in the Transporter-Linked Polymorphic Region of the gene SLC6A4, which codes for the serotonin transporter; 0=LL, 1=SL, 2=SS. Peer Stress = Chronic Peer Stress codes summed across the 3 time points, as assessed via Youth Life Stress Interview. Past Depression = Clinically significant depressive episode, as diagnosed via K-SADS prior to baseline. Future Depression = Clinically significant depressive episode, as diagnosed via K-SADS administered repeatedly every 6-months, occurred at some point after baseline through 36-months follow-up.
