"This volume presents a comprehensive framework for understanding short-term mood fluctuations and their relationship to longer-term differences in temperament and emotionality. David Watson integrates key findings from both literatures within the context of his ongoing 20-year research program on daily mood." "This book will be of interest to a broad audience of clinical professionals, as well as students, educators, and researchers working in the areas of emotion, personality, psychopathology, and health psychology. It also will serve as a text in advanced undergraduate and graduate-level courses."--BOOK JACKET.
