A brief review of health psychology shows that the early leadership began what has come to be a major alternative to traditional medical models of diagnosis and treatment. Numerous women were involved with these implementations and changes in the field. Many of the key developments within health psychology—for example, behavioral prevention, compliance, coping, health promotion, locus of control, and social support—reflect essentially feminist principles that emphasize the legitimate authority and significance of the individual. Feminist principles of equity and inclusiveness are also represented in emerging concerns that the health needs of many underprivileged groups deserve more focused attention, and, additionally, that entirely new areas of health can be profitably examined within the framework of health psychology.
