In the last 20-30 years, research on affective determinants of health behavior has proliferated. Highlighting this burgeoning area of research, Affective determinants of health behavior brings together contributions from leading experts who focus, in their chapters, on a fascinating range of affective concepts, including hedonic response, incidental affect, perceived satisfaction, anticipated affect, affective attitudes, affective associations, and more. In the first part of the book, the authors explore the role of affective concepts in health behavior, including theories of action control, dual-processing, temporal self-regulation, self-determination, and planned behavior, along with a new theory of hedonic motivation. The second part of the book focuses on the role of affective concepts in specific health behavior domains, including physical activity, eating, smoking, substance use, sex, tanning, blood donation, the performance of health professionals, cancer screenings, and cancer control. Affective determinants of health behavior offers readers an important window into existing research and serves as a showcase for important insights on new directions and implications for intervention.
