CHILDREN, YOUTH AND DRUGS--A LONGITUDINAL STUDY

拟议项目的总体目标是增加一个关于- 正在进行-但仍在设计阶段-预计的纵向研究， 儿童和青年（7、9、11、13和15岁的年龄"组群"） 年龄），其中研究部分直接侧重于药物使用。 具体目标包括：（1）更充分地审查 药物开发过程和启动因素 使用和与预防初次使用毒品有关的因素; 2)对同龄人和友谊的作用进行了重点检查， 药物使用开始、维持、递增和终止; 3） 以提供类型和模式的发生率和流行率， 高风险少数民族和盎格鲁人群体的药物使用（组合） 并获得关于毒品来源、使用量 给药方式以及使用的社会和物理环境; 4） 检查吸毒病因的相关因素， 测试整合理论解释启蒙的能力， 维持和终止药物使用;和5）检查 吸毒对家庭互动、学校 出勤率和表现，行为问题， 犯罪和其他与毒品有关的问题行为。 建议研究的样本是1500个概率样本 儿童和青少年从"高风险"的犯罪和 科罗拉多丹佛的吸毒社区。 大得多的 来自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 研究样本中包含的风险病例。 的组合 毒品使用和犯罪的纵向措施，个人 信仰和态度，人口统计和邻里 特征、同伴、家庭、学校和病史 影响，都来自一个概率样本，应该允许一个 拟议工作组将处理的若干重要问题 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.
