Practical Than a Good Theory” in Community Psychology
"There is nothing more practical than a good theory" (Lewin, 1952, p. 169). Since its inception, community psychology has been characterized by simultaneously pursuing the social utility of scientific knowledge and the theoretical value of practice (Lewin, 1946). Theories contribute to community change, while the lessons learned in community intervention in turn contribute to improve our knowledge of social reality. In terms of action research, theoretical models perform a central role in mediating between science and practice. However, when we ask community psychologists which models they consider essential for community research and action, the picture is very complex. Jason, Stevens, Ram, Miller, Beasley, and Gleason (2016) did this exercise, consulting the electronic mailing list of the Society for Community Research and Action. Both researchers and professionals involved in community intervention participate on this list, and the inquiry resulted in a list of approximately 32 theoretical frames. Without being exhaustive in the inquiry, it is striking the number and diversity of theoretical models mentioned. Some of them are not theoretical models. Others are not even part of psychology. As I will elaborate below, community research of the last several decades provides a basis for proposing a systematic view of community settings and a theory of the processes of community action and change.
