Health and rehabilitation psychology
Health and rehabilitation psychologists work closely with physicians to accomplish overall health-related goals. Health and rehabilitation psychologists strive to understand how biological, behavioral, and social factors influence health and apply psychological principles to promote optimal health and wellbeing. These specialized psychologists evaluate the emotional, cognitive, social, and interpersonal issues that result from and contribute to patients’ health status and medical treatment. Once assessed, interventions are designed to minimize the effects of medical conditions or assist with coping and adjustment with a focus on improved functioning and quality of life.
