PREVENTION OF RISK FOR DRUG USE IN RURAL ETHNIC MINORITY

项目一：这一项目将提供一个难得的机会，利用几个大型数据库，其中载有关于四个农村少数民族人口的广泛的药物使用和心理社会数据。上学的美国印第安人、墨西哥人、美国人、美国黑人和美国白色青少年。将提供更多的数据，以比较和对比这些人口与非农村族裔青年。所有研究都使用相同的仪器和调查方法，除了一个例外，使用分层随机抽样。该项目的目的是确定对预防有重大影响的因素，并就预防策略提出建议。这些数据将来自三民族预防研究中心正在进行的项目。数据收集工作将持续进行，为进行一系列分析提供机会，以便对所有调查结果进行交叉验证。除了交叉验证外，每项分析将按性别、学校年级和种族进行，以产生关于药物使用以及这些变量和人群之间相互作用的极其丰富的描述。提出了几种分析方法。第一，将对不同人群的吸毒流行率和吸毒模式进行比较，以确定个人和人口特征是否会导致差异。其次，将在不同种族群体中检查因变量和自变量，以建立可靠性和有效性估计值。将采用EQS验证性因素分析来检验测量不变性。第三，心理社会变量的平均差异将进行比较，并将产生一系列的EQS模型和差异阐明这些模型的一个核心要素将是检测物质使用的文化认同的影响。最后，在整个项目过程中，将定期公布调查结果，并提供给专业人员和从业人员。

Project I: This project will provide a rare opportunity to exploit several large databases that contain a wide range of drug use and psychosocial data on four rural, ethnic populations. American Indian, Mexican, American, Black American and White American adolescents attending school. Additional data will be available to compare and contrast these populations with non-rural youth of ethnic background. All of the studies from which the data are taken use the same instrumentation and survey methodology and, with one exception, use stratified random sampling. The intent of this project is to identify those factors that have strong implications for prevention and to make recommendations about prevention strategies. The data will come from projects in progress within the Tri-Ethnic Center for Prevention Research. Data collection will be ongoing, providing the opportunity for an array of analyses to be conducted for cross validation of all findings. In addition to cross validation, each analysis will take place by gender, grade in school and ethnicity to produce an extremely rich description of drug use and interactions among these variables and populations. Several analytic approaches are proposed. First drug use prevalence rates and patterns of use across populations will be compared to determine whether personal and demographic characteristics lead to differences. Second, dependent and independent variables will be examined across ethnic groups to establish reliability and validity estimates. EQS using confirmatory factor analysis will be employed to test for measurement invariance. Third, mean differences on psychosocial variables will be compared and a series of EQS models will be generated and differences elucidated A central element of these models will be to detect the impact of cultural identification on substance use. Finally, throughout the course of the project findings will be routinely published and made available to both professionals and practitioners.
