Population Assessment of Tobacco and Health (PATH) Study [United States] Special Collection Restricted-Use Files

The PATH Study was launched in 2011 to inform the Food and Drug Administration's regulatory activities under the Family Smoking Prevention and Tobacco Control Act (TCA). The PATH Study is a collaboration between the National Institute on Drug Abuse (NIDA), National Institutes of Health (NIH), and the Center for Tobacco Products (CTP), Food and Drug Administration (FDA). The study sampled over 150,000 mailing addresses across the United States to create a national sample of tobacco users and non-users. 45,971 adults and youth constitute the first (baseline) wave, Wave 1, of data collected by this longitudinal cohort study. These 45,971 adults and 9 to 11 sampled at Wave 1) make up the 53,178 participants that constitute the Wave 1 Cohort. Respondents are asked to complete an interview at each follow-up wave. Youth who turn 18 by the current wave of data collection are considered "aged-up adults" and are invited to complete the Adult Interview. Additionally, "shadow youth" are considered "aged-up youth" upon turning 12 years old, when they are asked to complete an interview after parental consent. At Wave 4, a probability sample of 14,098 adults, youth, and shadow youth ages 10 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 4. This sample was recruited from residential addresses not selected for Wave 1 in the same sampled PSUs and segments using similar within-household sampling procedures. This "replenishment sample" was combined for estimation and analysis purposes with Wave 4 adult and youth respondents from the Wave 1 Cohort who were in the civilian, noninstitutionalized population at the time of Wave 4. This combined set of Wave 4 participants, 52,731 participants in total, forms the Wave 4 Cohort. Please refer to the Restricted-Use Files User Guide that provides further details about children designated as "shadow youth" and the formation of the Wave 1 and Wave 4 Cohorts. Wave 4.5 is a special data collection for youth only who were aged 12 to 17 at the time of the Wave 4.5 interview. Wave 4.5 is the fourth annual follow-up wave for those who were members of the Wave 1 Cohort. For those who were sampled at Wave 4, Wave 4.5 is the first annual follow-up wave. Dataset 0001 (DS0001) contains the data from the Master Linkage file. This file contains 54 variables and 67,276 cases. The file provides a master list of every person's unique identification number and what type of respondent they were for each wave, starting with Wave 1. Dataset 1002 (DS1002) contains the data from the Wave 4.5 Youth (and Parent) Questionnaire. This file contains 1,617 variables and 13,131 cases. Datasets 1112, 1212, 1222, (DS1112, DS1212, and DS1222) are data files comprising the weight variables for Wave 4.5. The "all-waves" weight file contains weights for youth respondents in the Wave 1 Cohort who completed an interview for all waves in which they were old enough to do so or verified their information with the study for waves in which they were not old enough to be interviewed. There are two separate files with "single wave" weights: one for the Wave 1 Cohort and one for the Wave 4 Cohort. The "single-wave" weight file for the Wave 1 Cohort contains weights for youth who completed an interview in Wave 1 and responded to the interview in Wave 4.5, regardless of their participation in previous waves. The "single-wave" weight file for the Wave 4 Cohort contains weights for youth in the Wave 4 Cohort who responded to the interview in Wave 4.5.

PATH 研究于 2011 年启动，旨在为食品药品监督管理局（FDA）依据《家庭吸烟预防与烟草控制法案》（TCA）进行的监管活动提供信息。PATH 研究由国家药物滥用研究所（NIDA）、国家卫生研究院（NIH）及食品药品监督管理局（FDA）下属的烟草产品中心（CTP）共同合作开展。该研究对美国 15 万多个邮寄地址进行了抽样，以构建全国范围内的烟草使用者及非使用者样本。45,971 名成年人和青少年构成了该纵向队列研究的首次（基线）数据收集波次，即 Wave 1，他们组成了 53,178 人的 Wave 1 队列。受访者被要求在每次后续波次完成访谈。在当前数据收集波次达到 18 岁的青少年被视为“成年化青少年”，并被邀请完成成人访谈。此外，12 岁时被视为“成年化青少年”，在获得家长同意后，他们将完成访谈。在 Wave 4 中，从 Wave 4 时期的平民、非机构化人群中选取了 14,098 名成年人、青少年和 10 至 11 岁的“影子青少年”的概率样本。此样本来自未在 Wave 1 中被选中的相同初级抽样单元（PSU）和段的居住地址，并使用类似的户内抽样程序进行招募。这一“补充样本”与 Wave 4 成年人和青少年受访者相结合，后者来自 Wave 1 队列，并在 Wave 4 时期属于平民、非机构化人群，总共构成了 52,731 人的 Wave 4 队列。请参阅《受限使用文件用户指南》，以获取有关被指定为“影子青少年”的儿童以及 Wave 1 和 Wave 4 队列形成的相关详细信息。Wave 4.5 是仅针对当时处于 12 至 17 岁的青少年的特别数据收集波次。Wave 4.5 是 Wave 1 队列成员的第四次年度后续波次。对于 Wave 4 中的受访者，Wave 4.5 是他们的首次年度后续波次。Wave 5.5 于 2020 年进行，是针对 Wave 4 队列的 13 至 19 岁青少年和年轻成年人的特别数据收集波次。同年，Wave 4 队列中 20 岁及以上的成年受访者通过 PATH 研究成人电话调查（PATH-ATS）进行了访谈。数据集 1002（DS1002）包含了 Wave 4.5 青少年及家长问卷的数据。该文件包含 1,617 个变量和 13,131 个案例。在这些案例中，11,378 个案例为持续参与的青少年，他们已完成之前的青少年访谈。其余 1,753 个案例为“成年化青少年”，他们之前作为“影子青少年”被抽样。数据集 1112、1212 和 1222（DS1112、DS1212 和 DS1222）是 Wave 4.5 的权重变量数据文件。‘all-waves’ 权重文件包含 Wave 1 队列中完成 Wave 4.5 青少年访谈并完成访谈（如果年龄足够）或通过研究验证其信息（如果未足够龄接受访谈）的参与者的权重。有两个单独的“single wave”权重文件：一个用于 Wave 1 队列，另一个用于 Wave 4 队列。Wave 1 队列的“single-wave”权重文件包含在 Wave 1 和 Wave 4.5 中完成访谈的青少年的权重，无论他们是否参与了中间波次。Wave 4 队列的“single-wave”权重文件包含 Wave 4 队列中所有 Wave 4.5 青少年访谈受访者的权重。数据集 1402（DS1402）包含了 Wave 4.5 青少年及家长州标识符数据，包含 5 个变量和 13,131 个案例。州标识符数据集包括 PERSONID 以将州标识符与问卷数据链接，以及指定州的 3 个变量（联邦信息处理系统（FIPS）州代码、州缩写和州全名）。此数据集中的州标识符值代表参与者在 Wave 4.5 时期的居住州。数据集 1503（DS1503）包含来自 Wave 1、Wave 2、Wave 3、Wave 4 和 Wave 4.5 问卷调查的回答数据，表明参与者是否曾使用过各种烟草产品。
