Focusing on the contributions of psychology to prevention in Public Health, this paper presents a review of several articles concerning the health behavior of individuals and the relationships between environmental conditions, behavior and health. On the other hand, taking into consideration points of contact and divergence between clinical psychology and Public Health, this review suggests that community psychology should be the area of psychology whose objectives are closer to those of the World Health Organization - a suggestion based on their common concern with the relationships between organizational systems and individual behavior, and the development of social systems congruent with human needs. Still, given the scarcity of available empirical data, this paper ends with the conclusion that a more effective contribution to Public Health would be attained if a greater number of research projects were developed clarifying the relationships between individual behavior and organizational and community environments.
