This study was undertaken in an attempt to clarify and delineate the definition of peace psychology and the role of peace psychologists. Members of Division 48 of the American Psychological Association were asked to respond to three questions: (1) What is the definition of peace psychology? (2) How is peace psychology a psychology? and (3) What does a peace psychologist do? The survey revealed that peace psychology has different meanings, different units of analyses, and different applications for different people. While a diverse range of opinions exists, there does appear to be a general consensus regarding definition and application. The definition of the field of peace psychology that emerges involves psychologists who are professionally and personally committed toward studying and promoting peace within and between all levels of human relations.
