Modifying and developing health behavior

The literatures on both behavior modification and behavioral development have engendered innovations in public health programs, addressing problems of patient adherance to preventive and therapeutic regimens, delay in seeking diagnosis of illness symptoms, risk-taking behavior, and other aspects of lifestyle associated with health. Because most of this literature derives from psychology, there has been a distinct bias in the construction of interventions, pointing them directly at individuals, usually in a counseling or small group mode of delivery. These developments served public health well enough during a decade or so when the preoccupation was with utilization of health services and medical management of chronic diseases. With the publication of the Lalonde Report in Canada in 1974, the passage of Public Law 94-317 in 1976 in the United States, and similar initiatives in other English-speaking and European countries, the recognition of the greater complexities of lifestyle development and modification in the absence of symptoms has taken hold. Policy makers and public health workers seek a more efficient and equitable set of strategies to meet the behavioral health challenges of modern society without placing the entire weight of responsibility for behavior on the individual or on therapeutic practitioners. Concurrently, on a more global scale and in the developing countries, a concern has emerged for strategies that give individuals, families, and communities a greater role in deciding their own health priorities. The convergence of these two trends--one seeking to distribute responsibility for lifestyle more equitably and the other seeking to distribute responsibility for planning health programs more equitably --calls for policies, strategies, and interventions that will place similar emphasis on health education and organizational, economic, and environmental supports for health behavior. The combination of these elements of support for behavior calls, in turn, for research and more inventive applications of theory from sociology, political science, economics, and anthropology. Public health workers will need to become more conversant and facile in these social sciences, as they have in psychology and its applications in the recent past.
