This important volume offers a comprehensive overview of new approaches to health-related behavior from a self-regulation perspective. It outlines assumptions on which self-regulation theories are based, discusses recent research and draws out the implications for practice with a particular focus on changing health behavior. Reflecting the notion that health-promoting behavior is goal-directed, chapters consider key factors such as: * social influences * the nature of health goals * health risk behavior * unintentional behavior * maintaining self-control * frustrations in goal striving * maintaining health behavior change. Self-Regulation in Health Behavior offers a valuable new perspective on health behavior. It is essential reading for MSc students in health psychology, as well as researchers, practising health psychologists and clinical health psychologists.
