Document Summary
The medical model proposes that it is useful to think of abnormal behaviour as a disease. Viewing as disease helped people to be more sympathetic towards mentally ill and not yknow, put them in cages. Diagnosis involves distinguishing one illness from another. Etiology refers to the apparent causation and developmental history of an illness. Prognosis is a forecast about the probable course of an illness. Criteria of abnormal behaviour: deviance - when people violate the norms of society. Ex: transvestic fetishism - sexual disorder in which a man achieves sexual arousal by dressing in women"s clothing: maladaptive behaviour - everyday adaptive behaviour is impaired. Ex: cocaine begins to interfere with a person"s social or occupational functioning: personal distress - individual"s report of great personal distress. When only one criterion is met, people are viewed as disordered. Diagnosis involves value judgement of a person"s view of what is normal. People are judged to have psychological disorder if behaviour is extreme.
