This compelling work brings together leading social psychologists and evaluators to explore the intersection of these two fields and how their theory, practices, and research findings can enhance each other. An ideal professional reference or student text, the book examines how social psychological knowledge can serve as the basis for theory-driven evaluation; facilitate more effective partnerships with stakeholders and policy makers; and help evaluators ask more effective questions about behavior. Also identified are ways in which real-world evaluation findings can identify gaps in social psychological theory and test and improve the validity of social psychological findings; for example, in the areas of cooperation, competition, and intergroup relations. The volume includes a useful glossary of both fields' terms and offers practical suggestions for fostering cross-fertilization in research, graduate training, and employment opportunities. Each tightly edited chapter features an introduction and concluding reflection/discussion questions from the editors.
