Document Summary
The medical model: proposes that it is useful to think of abnormal behaviour as a disease. Criteria of abnormal behaviour: deviance: people are often said to have a disorder because their behaviour deviates what their society considers acceptable. When people violate these standards and expectations, they may be labelled mentally ill: maladaptive behaviour: people are judged to have a psychological disorder because their everyday behaviour is impaired. This is the key criterion in the diagnosis of substance-use (drug) disorders: personal distress: the psychological disorder diagnosis is based on an individual"s report of great personal distress. Usually the criterion met by people who are troubled by depression or anxiety disorders. Epidemiology: the study of the distribution of mental or physical disorders in a population. Prevalence: refers to the percentage of a population that exhibits a disorder during a specified time period. Etiology: refers to the apparent causation and developmental history of an illness.
