Would Changing an Individual’s Beliefs Improve Their Health

Health psychology is the application of psychological theory and research to health, illness and health care, which deals with individual behavior in the social context. Psychosocial aspects and determinants are kept in consideration to understand human behavior. It also tries to understand and promote behavioral changes. One basic assumption in health psychology is that to change people’s behavior—at least through health promotion interventions—it is necessary to understand the psychosocial determinants of behavior. For example, due to lack of motivation/ willpower when a harmful user fails to stop taking alcohol, requires another kind of intervention than that addict who fails to stop taking drinks because of a lack of family/social support.
In the traditional viewpoint absence of disease was known as health. This concept was known as a biomedical concept, which has its base in the "germ theory of disease" which dominated medical thought at the turn of the 20th century. The medical professionals of that term were treating the human body as a machine. Any sort of disease was taken as a fault in the machine and the doctor’s task was to repair the machine. Therefore the health became the ultimate goal of medicine. The criticism then started against the biomedical concept as it was minimized the role of the environmental, social, psychological and cultural determinants of health. The biomedical model, for all its remarkable success in treating disease, was found inadequate to solve some of the major health problems of mankind (e.g., malnutrition, chronic diseases, accidents, drug abuse, mental illness, environmental pollution, population explosion) by elaborating the medical technologies.&nbsp.&nbsp.
