Clinical psychologists evaluate people in various settings, and give diagnostic tests. They may provide individual, family, or group psychotherapy, and design and implement behavior modification programs. Some
clinical psychologists collaborate with physicians and other specialists to develop and implement treatment and intervention programs with greater compliance results. Other clinical psychologists work in
universities and medical schools, where they train graduate students in the delivery of mental health and behavioral medicine services. Some administer community mental health programs.
Areas of specialization within clinical psychology include health psychology, sports psychology, neuropsychology, and geropsychology. Health psychologists promote good health through health maintenance counseling
programs designed to help people achieve goals such as to stop smoking or lose weight. They also work with people on the psychological aspects of chronic illness and disability. Sports psychologists work with
athletes on such factors as mental preparation, anxiety management and performance anxiety.
Neuropsychologists study the relation between the brain and behavior. They often work in stroke and head injury programs. Geropsychologists deal with the special problems faced by the elderly. The
emergence and growth of these specialties reflects the increasing participation of psychologists in providing direct services to special patient populations.
