Health Psychology: Psychosocial and Biobehavioral Aspects of Chronic Disease Management

Psychosocial factors appear to impact upon the development and progression of such chronic diseases as coronary heart disease, cancer, and HIV/AIDS. Similarly, psychosocial interventions have been shown to improve the quality of life of patients with established disease and seem to influence biological processesthought to ameliorate disease progression. Small-scale studies are useful for specifying the conditions under which psychosocial factors may or may not impactquality of life, biological factors, and disease progression. They are also useful for informing us about the conditions under which psychosocial interventions can serve as adjuvants (e.g. adherence training) to medical treatments. Only large-scale clinical trials, however, can determine the extent to which these psychosocial interventions may impact morbidity and mortality.
