PATH Questionnaire Reliability and Validity Study

项目总结/摘要 随着新一代烟草产品的上市或开发，监测至关重要， 描述美国人口中烟草使用的变化模式和相关性。人口 烟草与健康评估（PATH）研究是国家卫生部开展的第一项大型研究工作。 美国卫生研究院（NIH）和美国食品药品监督管理局（FDA）。PATH是一项全国性的纵向研究， 烟草使用和健康，这是继约46,000名美国家庭居民年龄在12岁及以上。 Westat是一家研究公司，领导PATH的开发、数据收集和分析。 系统已经在Westat到位，本提案旨在估计重测信度， PATH问卷的有效性。PATH成人和青年回合的独立可靠性和有效性研究 建议采用四种手段，在一个子样本中对全国875名答卷人进行访谈 路径示例区域。受访者将接受两次访问，并于10至15日内完成重新访问。 第一次面试后17天。对于发现差异的项的子集， 调查问卷将包括旨在揭示差异性质的调查。评估 烟草使用唾液样本关键项目答案的有效性将进行生物标志物分析， 在重新面试结束时，面试官将拍摄参与者使用的产品，并将 与调查问卷中的品牌自我报告相比。方法上的其他改进和 将进行分析，以扩大研究的科学价值， 与不同的可靠性水平相关联，确定影响可靠性的问题的特征， 的答案，并检查收敛的不同方法估计可靠性。PATH将服务于 研究人员，机构和政策制定者提供最全面和最新的数据， 烟草和物质使用的景观的任何调查。因此，关键是要确定 PATH数据。拟议的小组包括经验丰富的调查方法专家和烟草控制专家 专家。该项目将增进对可靠烟草调查答复的个人层面预测因素的了解 以及调查项目本身可能产生更可靠和有效报告的特点; 这些发现将被纳入新的工具，以预测调查问题的可靠性， 物质使用行为研究中的测量实践。

PROJECT SUMMARY/ABSTRACT With a new generation of tobacco products either on the market or being developed, surveillance is critical to describe the changing patterns and correlates of tobacco use in the U.S. population. The Population Assessment of Tobacco and Health (PATH) Study is the first large research effort undertaken by the National Institutes of Health (NIH) and the Food and Drug Administration (FDA). PATH is a national longitudinal study of tobacco use and health that is following approximately 46,000 U.S. household residents ages 12 and older. Westat is the research company leading the development, data collection, and analyses of PATH. Building on systems that are already in place at Westat, this proposal seeks to estimate the test-retest reliability and validity of the PATH questionnaires. A separate reliability and validity study of the PATH adult and youth round four instruments is proposed in which a national sample of 875 respondents will be interviewed in a subsample of the PATH sample areas. Respondents will be interviewed twice, with the re-interview completed within 10 to 17 days after the initial interview. For a subset of the items on which discrepancies are found, the questionnaire will include probes designed to shed light on the nature of the discrepancy. To assess the validity of answers to key items on tobacco use saliva specimens will be analyzed for biomarkers and, at the end of the reinterview, the interviewer will photograph the products used by the participant and they will be compared to the brands self-reported in the questionnaire. Additional methodological enhancements and analyses to broaden the scientific value of the study will be conducted to identify person-level variables associated with differing levels of reliability, identify characteristics of the questions that affect the reliability of the answers, and examine the convergence of different methods for estimating reliabilities. PATH will serve researchers, agencies, and policy makers with the most comprehensive and up-to-date data on the changing tobacco and substance use landscape of any survey to date. It is, thus, crucial to establish the reliability of the PATH data. The proposed team includes experienced survey methodology experts and tobacco control specialists. The project will advance knowledge of person-level predictors of reliable tobacco survey responses as well as characteristics of the survey items themselves that may produce more reliable and valid reporting; these findings will be incorporated in new tools to predict the reliability of survey questions, advancing measurement practices in the study of substance use behaviors.
