CHAPTER 5: RESEARCH METHODS IN THE STUDY OF ABNORMAL PSYCHOLOGY SCIENCE AND SCIENTIFIC METHODS Science: The pursuit of systematized knowledge through observation. Theory: Set of propositions meant to explain a class of phenomena. Hypotheses: Expectations about what should occur if a theory is true. The generation of a theory is perhaps the most challenging part of the scientific enterprise. One earlier school of thought, called operationism, proposed that each concept take as its meaning a single observable and measurable operation. In this way each theoretical concept would be nothing more than one particular measurable event. For example, anxiety might be identified as nothing more than scoring above 50 on a particular anxiety questionnaire. THE RESEARCH METHODS OF ABNORMAL PSYCHOLOGY The case study has been used to: 1. Provide a detailed description of a rare or unusual phenomenon and of important, often novel, methods or procedures of interviewing, diagnosis and treatment. 2. Disconfirm allegedly universal aspects of a particular theoretical proposition. 3. Generate hypotheses that can be tested through controlled research. Multiple personality is known also as dissociative identity disorder. GENERATING HYPOTHESES A case study may reveal principles characteristic of people in general and is unable to provide satisfactory evidence concerning cause-effect relationships. Epidemiology: The study of the frequency and distribution of a disorder in a population. Three features of a disorder: 1. Prevalence- the proportion of a population that has the disorder at a given point or period of time. 2. Incidence- the number of new cases of the disorder that occur in some period, usually a year. www.notesolution.com
