An important developmental task during adolescence is learning to make decisions, experiencing the related positive and negative consequences, and learning from these outcomes. However, a youth's ability to make competent decisions is sometimes called into question because adolescence is also often a time of engagement in risky behaviors. This article provides an overview of adolescent decision making, presents models of health-related decision making, and discusses factors which influence the decision-making process during adolescence. It concludes with implications that are relevant to those who work with youth. (Contains 2 figures and 1 footnote.)
