| Abstract: | We tested 3 competing hypotheses regarding the relation between pubertal timing and substance initiation in adolescence: the early timing, off-time, and stressful change hypotheses. We used longitudinal data from the Developmental Pathways Project (N = 521). Youth reported whether they had ever tried alcohol, tobacco, or marijuana at baseline, and then again at 6-, 12-, 18-, 24-, 36-, and 72-month follow-up interviews. We estimated interval censored parametric survival models and tested interactions between pubertal timing and gender and race variables. We found robust support for the early timing hypothesis, but no support for the off-time and the stressful change hypotheses. |
