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 participants in the Wave 1 Cohort who completed a Wave 4.5 youth interview and completed interviews (if old enough to do so) or verified their information with the study (if not old enough to be interviewed) in Waves 1, 2, 3, and 4. 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 in Wave 4.5, regardless of their participation in the intervening waves. The "single-wave" weight file for the Wave 4 Cohort contains weights for all Wave 4.5 youth interview respondents in the Wave 4 Cohort. Dataset 1402 (DS1402) contains the Wave 4.5 State Identifier data for Youth (and Parents) and has 5 variables and 13,131 cases. The State Identifier dataset includes PERSONID for linking the State Identifier to the questionnaire data and 3 variables designating the state (state FIPS, state abbreviation, and full name of the state). The State Identifier values in this dataset represent participants' state of residence at the time of Wave 4.5. Dataset 1503 (DS1503) contains data derived from responses to questionnaires in Wave 1, Wave 2, Wave 3, Wave 4, and Wave 4.5 indicating if participants had ever/never used various tobacco products as of the Wave 4.5 data collection period. This data file contains 26 variables for all 67,276 study participants as of the Wave 4.5 data collection.

PATH 研究（PATH Study）于 2011 年启动，旨在为美国食品药品监督管理局（Food and Drug Administration，FDA）根据《家庭吸烟预防与烟草控制法案》（Family Smoking Prevention and Tobacco Control Act，TCA）进行的监管活动提供信息。PATH 研究由美国药物滥用研究所（National Institute on Drug Abuse，NIDA）、美国国立卫生研究院（National Institutes of Health，NIH）和食品药品监督管理局烟草产品中心（Center for Tobacco Products，CTP）共同协作进行。研究通过在美国 150,000 个邮寄地址中进行抽样，构建了一个全国性的烟草使用者与非使用者样本。其中，45,971 名成年人和青少年构成了该纵向队列研究的第一波（基线波）数据，即 Wave 1。在 Wave 1 中，这 45,971 名成年人和 9 至 11 岁的儿童共同组成了 53,178 名参与者的 Wave 1 队列。受访者被要求在每次后续波次中完成一次访谈。在当前数据收集波次中达到 18 岁的青少年被视为 '成年化成人' 并受邀完成成人访谈。此外，'影子青少年' 在 12 岁时被视为 '成年化青少年'，并在获得家长同意后完成访谈。在 Wave 4 中，从 Wave 4 时点的平民、非机构化人群中选取了 14,098 名成年者、青少年和 10 至 11 岁的 '影子青少年' 作为概率样本。该样本从 Wave 1 中未选中的居住地址以及相似的抽样单元（PSUs）和细分市场使用类似的户内抽样程序招募。这个 '补充样本' 在估计和分析目的上与 Wave 4 成年和青少年受访者相结合，这些受访者来自 Wave 1 队列，并在 Wave 4 时点属于平民、非机构化人群。这组结合的 Wave 4 参与者，总计 52,731 名，构成了 Wave 4 队列。请参阅《受限使用文件用户指南》，其中提供了关于被指定为 '影子青少年' 的儿童以及 Wave 1 和 Wave 4 队列形成的进一步细节。Wave 4.5 是针对 Wave 4 时点年龄在 12 至 17 岁的青少年进行的特别数据收集。Wave 4.5 是 Wave 1 队列成员的第四年年度后续波次。对于在 Wave 4 中被抽样的参与者，Wave 4.5 是他们的第一年年度后续波次。数据集 0001（DS0001）包含主链接文件的数据。该文件包含 54 个变量和 67,276 个案例，提供了每个受访者在每个波次中独特识别号码及其受访者类型的总清单，始于 Wave 1。数据集 1002（DS1002）包含 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。数据集 1112、1212、1222（DS1112、DS1212 和 DS1222）是包含 Wave 4.5 权重变量的数据文件。'全波次' 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）或向研究验证其信息（如果年龄不足以接受访谈）的 Wave 1、2、3 和 4 波次参与者的权重。有两个单独的 '单波次' 权重文件：一个针对 Wave 1 队列，一个针对 Wave 4 队列。Wave 1 队列的 '单波次' 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，无论他们在中间波次中是否参与。Wave 4 队列的 '单波次' 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 Wave 4.5 青少年（及家长）州标识符数据，有 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 3 个变量指定州（州 FIPS、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 时的居住州。数据集 1503（DS1503）包含 Wave 1、Wave 2、Wave 3、Wave 4 和 Wave 4.5 中问卷的回答，表明参与者在 Wave 4.5 数据收集期间是否曾经/从未使用过各种烟草产品。该数据文件包含 26 个变量，涵盖 Wave 4.5 数据收集时的所有 67,276 名研究参与者。该文件仅提供参考，以简化烟草使用变量的定义。
