[Prevalence and a drug use development model for the study of adolescent drug use in Japan].
The purposes of this study were to estimate the prevalence of drug use, to examine the correlation between drug use and drinking/smoking in Japan, and to test a developmental model of adolescents' drug use based on three basic theories of deviance: Strain, Social control, and Differential association. The survey was conducted from April to May, 1996, in 14 public high schools in Tokyo, using anonymous self-reporting. A total of 4,171 (99.45%) students responded to our questionnaire. It included central concept items in the three deviant theories, beliefs about the ill effects of drugs, sex, grades, etc. The following findings were obtained: 1) Among the subjects, 255 students (6.1%) reported drug use within the past year. Of these drug users, 73.3% used drugs soon after being "tempted" by friends. Responding to "When was it.", as a first year junior high school was the most common first experience, and the next most common was during the sixth year of elementary school. 2) Drinking and smoking appeared to be gateway drugs for adolescents in Japan as has been shown in the United States. 3) Multiple regression and logistic multiple regression analyses suggested that differential association variables were far more powerful predictors of adolescent drinking, smoking and drug use than either the control or strain variables. Results provided modest support for the Differential Association Theory as an explanation of drug use. 4) LISREL's goodness-of-fit statistic indicated a much better fit between the model and the data. (CN: 282, GFI: 0.967, AGFI: 0.941). These findings show two processes by which adolescents become involved in drug use. Strain and Social Control do not directly affect drug use. However, Social Control is important because it works indirectly, through Differential Association resulting in drug use. Second, though weaker, Differential Association appears to lead to dangerous beliefs in drug use followed by actual drug use.
