We now explore positive psychology research in four areas. For each one I’ll describe some of the main concepts, offer a sample of research studies, and suggest possible coaching applications. The first area of theory/research is positive emotion and the surprisingly powerful role it plays in personal and professional effectiveness. Second I present the concept of “flow,” the conditions that foster it and how coaches might use this information. Third I give a short overview of the components of hope and the effectiveness of hope therapy. Last is a description of the classification of strengths, the Values in Action survey (or as some have dubbed it, the “unDSM”).
