The Oxford Handbook of Positive Psychology studies the burgeoning field of positive psychology, which, in recent years, has transcended academia to capture the imagination of the general public. The book provides a roadmap for the psychology needed by the majority of the population—those who don’t need treatment, but want to achieve the lives to which they aspire. The articles summarize all of the relevant literature in the field, and each is essentially defining a lifetime of research. The content’s breadth and depth provide a cross-disciplinary look at positive psychology from diverse fields and all branches of psychology, including social, clinical, personality, counseling, school, and developmental psychology. Topics include not only happiness—which has been perhaps misrepresented in the popular media as the entirety of the field—but also hope, strengths, positive emotions, life longings, creativity, emotional creativity, courage, and more, plus guidelines for applying what has worked for people across time and cultures.
