CHILDREN, YOUTH AND DRUGS--A LONGITUDINAL STUDY

拟议项目的总体目标是加强对- 正在进行-但仍处于设计阶段-计划进行纵向研究 儿童和青年(7、9、11、13和15岁的“年龄组” 年龄)，有一个直接侧重于药物使用的研究部分。 具体目标包括1)更充分地审查 药物形成的发展过程及影响因素 预防初次吸毒的使用情况和相关因素； 2)重点研究同龄人和友谊在 开始、维持、升级和终止药物使用；3) 提供类型和模式的发病率和流行率 高危少数民族和盎格鲁族人群的药物使用情况(组合) 并获得有关毒品来源、使用量、 管理方式、使用的社会和物质环境；4) 检查围绕药物使用的病因的因素，并 测试一个综合理论解释启蒙的能力， 维持和终止药物使用；以及5)检查 吸毒对家庭、学校互动的影响 出勤和表现，行为问题和 青少年犯罪，以及其他与毒品有关的问题行为。 拟议研究的样本是1500个概率样本 患有“高危”犯罪的儿童和青少年 科罗拉多州丹佛市的吸毒社区。一个大得多的 这些社区的年轻人的概率样本将是 最初筛查的风险和不成比例的高风险 研究样本中包括的风险案例。这两种技术的结合 个人吸毒和犯罪的纵向测量 信仰和态度、人口统计和社区 特征，以及同伴、家庭、学校和医学史 所有影响都来自一个概率样本，应该允许 拟议中需要解决的若干重要问题 项目。

The overall objective of the proposed project is to augment an on- going-but still in the design phase-projected longitudinal study of children and youth (age "cohorts" of 7, 9, 11, 13, and 15 years of age) with a research component that focuses directly on drug use. The specific objectives include 1) to more adequately examine the developmental process and factors surrounding initiation into drug use and factors associated with the prevention of initial drug use; 2) a focused examination of the role of peers and friendships in drug use initiation, maintenance, escalation, and termination; 3) to provide incidence and prevalence of types and patterns (combinations) of drug use in high risk minority and anglo groups and to obtain information about sources of drugs, amounts used, mode of administration, and social and physical setting of use; 4) to examine the factors surrounding the etiology of drug use and to test the ability of an integrated theory to explain initiation, maintenance, and termination of drug use; and 5) to examine the consequences of drug use for family interactions, school attendance and performance, behavioral problems and delinquency, and other drug related problem behavior. The sample of the proposed study is a probability sample of 1500 children and adolescents drawn from "high risk" delinquency and drug use neighborhoods of Denver, Colorado. A much larger probability sample of youth from these neighborhoods will be initially screened for risk and a disproportionate number of high risk cases included in the study sample. The combination of longitudinal measures of drug use and delinquency, personal beliefs and attitudes, demographic and neighborhood characteristics, and peer, family, school and medical history influences, all from one probability sample, should permit a number of important issues to be addressed by the proposed project.
