PREVENTION OF RISK FOR DRUG USE IN RURAL ETHNIC MINORITY

项目一：该项目将提供一个难得的机会，利用几个大型数据库，这些数据库包含关于四个农村族裔人口的广泛的药物使用和心理社会数据。美国印第安人、墨西哥人、美国人、美国黑人和美国白人青少年上学。将提供更多数据，将这些人口与具有族裔背景的非农村青年进行比较。所有获取数据的研究都使用相同的工具和调查方法，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具有重大影响的因素，并就预防战略提出建议。这些数据将来自三族预防研究中心内正在进行的项目。将继续进行数据收集，为对所有调查结果进行交叉验证提供一系列分析的机会。除了交叉验证外，每个分析都将按性别、学校年级和种族进行，以产生对药物使用以及这些变量和人口之间相互作用的极其丰富的描述。提出了几种分析方法。首先，将对不同人群的吸毒流行率和使用模式进行比较，以确定个人和人口特征是否会导致差异。其次，将对各民族的因变量和自变量进行检查，以建立信度和效度估计。使用验证性因子分析的均商将被用来检验测量不变性。第三，将比较心理社会变量的平均值差异，并生成一系列EQS模型并阐明差异。这些模型的核心要素将是检测文化认同对物质使用的影响。最后，在整个项目过程中，将定期公布调查结果，并向专业人员和从业人员提供。

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.
