'Bringing together leading scholars from the several disciplines needed to advance understanding of how self-regulation processes enable individuals to contribute to their positive behavior and health, both during adolescence and the entire life span, Professors Oettingen and Gollwitzer have created a work that uniquely advances theory, research, and application. Self-Regulation in Adolescence is required reading for scholars and practitioners interested in describing, explaining, and optimizing the role of self-regulation in positive youth development.'
