Book excerpt: Cultures, Communities, Competence, and Change provides a transcultural psychosocial conception of the nature of individual and social activity. The author presents an integrated view of how people develop a psychosocially-based awareness of themselves and their milieus to shape what he refers to as their `internested' social systems. In so doing he challenges current deficit/prevention emphases in the helping disciplines and promotes a constructive, prosocial model of individual and social approaches to change.
