Mental health
Clinical psychology is the application of psychology to the understanding, treatment, and assessment of psychopathology, behavioral or mental health issues. It has traditionally been associated with counselling and psychotherapy, although modern clinical psychology may take an eclectic approach, including a number of therapeutic approaches. Typically, although working with many of the same clients as psychiatrists, clinical psychologists do not prescribe psychiatric drugs. Some clinical psychologists may focus on the clinical management of patients with brain injury. This area is known as clinical neuropsychology.
In recent years and particularly in the United States, a major split has been developing between academic research psychologists in universities and some branches of clinical psychology. Many academic psychologists believe that these clinicians use therapies based on discredited theories and unsupported by empirical evidence of their effectiveness. From the other side, these clinicians believe that the academics are ignoring their experience in dealing with actual patients. The disagreement has resulted in the formation of the American Psychological Society by the research psychologists as a new body distinct from the American Psychological Association.
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 or in research into the psychological impact of health and social care.
The majority of work performed by clinical psychologists tends to be done inside a Cognitive-Behaviorial therapy (CBT) framework. CBT is an umbrella term that refers to a number of therapies which focus on changing cognitions and/or behaviors, rather than changing behavior exclusively, or discovering the unconscious causes of psychopatholgy (as in the psychodynamic school). The two most famous CBT therapies are Aaron T. Beck’s cognitive therapy and Albert Ellis’s rational emotive behaviour therapy (with cognitive therapy being, by far, the most extensively studied therapy in contemporary clinical psychology).
