Prevention Science〔Coie, J. D., Watt, N. F., West, S. G., Hawkins, J. D., Asarnow, J. R., Markman, H. J., Ramey, S. L., ... Long, B. (January 01, 1993). The science of prevention. A conceptual framework and some directions for a national research program. The American Psychologist, 48, 10, 1013-22. 〕 is the application of a scientific methodology that seeks to prevent or moderate major human dysfunctions before they occur. Regardless of the type of issue on hand, the factors that lead to the problem must be identified and addressed. Prevention research is thus focused primarily on the systematic study of these potential precursors of dysfunction, also known as risk factors; as well as components or circumstances that reduces the probability of problem development in the presence of risk, also known as protective factors. Preventive interventions aim to counteract risk factors and reinforce protective factors in order to disrupt processes or situations that give rise to human or social dysfunction. == Components of Prevention Science〔Mrazek, P. B., Haggerty, R. J., Institute of Medicine (U.S.)., & United States. (1994). Reducing risks for mental disorders: Frontiers for preventive intervention research. Washington, D.C: National Academy Press.〕 == Epidemiology The prevalence, distribution, and determinants of the problem in time and space. Epidemiological investigations can be carried out through surveillance and descriptive studies to determine its extent. Etiology The causes of such positive or negative outcomes, with an emphasis on risk and protective factors. Also known as the Theory of Causation. Efficacy Trials Scientific experiments that test the preventive intervention programs ability to prevent the problem under favorable conditions. Under these optimal conditions, the researcher has control over the intervention and how it is delivered. If the test finds significant desirable effects, the intervention program is considered to be efficacious. Effectiveness Trials Scientific experiments that test the preventive intervention programs ability to prevent the problem under real world conditions. The setting and the kinds of people in the experiment should be very similar to the actual targeted population in a particular location. Dissemination Research Analyzes how tested and effective prevention intervention programs may be spread to reduce problems at a larger scale. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prevention science」の詳細全文を読む スポンサード リンク
