CAPTURING HIGH-RISK STUDENTS IN CLASSROOM-BASED SURVEYS

描述：(申请人摘要) 大多数关于青少年吸毒的研究是以学校为基础的，并假设 某一天在教室里收集的数据代表了 青少年人口。然而，在市中心的学校，旷课是一种 顽固的问题。当进行这种校本测量时， 将会有相当数量的学生被错过。事实上，这可能是 青少年走出教室的风险更大。特别的 值得关注的是与毒品相关的危险行为之间的潜在区别 那些在教室里的学生和那些不在教室里的学生。因此，要达到 更需要预防性规划、努力的青少年 首先需要对一刀切校本引入的偏见进行评估 取样。 这项研究建议确定在城市中以课堂为基础的抽样 当感兴趣的人群为 青少年。它将测量与以下相关的偏差：1)限制 对当时在教室里的学生的青少年样本 调查管理，2)将缺勤的任何调整基于 自我确认为长期缺课的学生，恰好在 调查管理的时间。 尽管这项研究的地理范围仅限于纽约市，但其发现 将与许多市中心的学校系统相关，这些学校的 旷工。

DESCRIPTION: (Applicant's Abstract) The majority of research on adolescent drug use is school-based and assumes that data collected in the classroom on a single day are representative of the adolescent population. However, in inner-city schools, absenteeism is a recalcitrant problem. When such school-based surveying is performed, a substantial number of students will be missed. In fact, it may be the adolescent out of the classroom who is at greater risk. Of particular concern is the potential distinction between the drug-related risk behaviors of those students in the classroom and those who are not. Thus, to reach the adolescents who are at greater need for preventive programming, efforts first need to be made to assess the bias introduced in one-shot school-based sampling. This research proposes to determine if classroom-based sampling in urban settings introduces measurable bias when the population of interest is adolescents. It will measure the bias associated with: 1) limiting the sample of adolescents to those students who are in the classroom at the time of survey administration, 2) basing any adjustments for absenteeism on the self-identified chronically absent student who happens to be in the class at the time of survey administration. Although the study is geographically limited to New York City, its findings will be relevant to many inner-city school systems with high rates of absenteeism.
