Precise shifts in the ways people make sense of themselves, others, and social situations can help people flourish. This compelling handbook synthesizes the growing body of research on wise interventions–brief, nonclinical strategies that are wise to the impact of social-psychological processes on behavior. Leading authorities describe how maladaptive or pejorative interpretations can undermine people’s functioning and how they can be altered to produce benefits in such areas as academic motivation and achievement, health, well-being, and personal relationships. Consistently formatted chapters review the development of each intervention, how it can be implemented, its evidence base, and implications for solving personal and societal problems.
