Whereas clinical psychology focuses on mental health and neurological illness, health psychology is concerned with the psychology of a much wider range of health-related behavior including healthy eating, the doctor-patient relationship, a patient's understanding of health information, and beliefs about illness. Health psychologists may be involved in public health campaigns, examining the impact of illness or health policy on quality of life and in research into the psychological impact of health and social care.
Clinical psychology An important area of expertise for many clinical psychologists is psychological assessment, and there are indications that as many as 91% of psychologists engage in this core clinical practice.[29] Such evaluation is usually done in service to gaining insight into and forming hypotheses about psychological or behavioral problems. As such, the results of such assessments are usually used to create generalized impressions (rather than diagnoses) in service to informing treatment planning. Methods include formal testing measures, interviews, reviewing past records, clinical observation, and physical examination.[2]
