Population Assessment of Tobacco and Health (PATH) Study [United States] Special Collection Public-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 youth along with 7,207 "shadow youth" (youth ages 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 Public-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 (public-use) Master Linkage file. This file contains 18 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 1,395 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.

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）实施的监管活动提供信息。PATH 研究（PATH Study）是国家药物滥用研究所（National Institute on Drug Abuse, NIDA）、美国国立卫生研究院（National Institutes of Health, NIH）与食品药品监督管理局烟草产品中心（Center for Tobacco Products, CTP）之间的合作项目。研究通过对美国超过150,000个邮寄地址的抽样，构建了一个涵盖烟草使用者和非使用者的全国性样本。其中，45,971名成人和青少年构成了该纵向队列研究的第一波（基线）数据，即 Wave 1。这45,971名成人和青少年以及7,207名“影子青少年”（在 Wave 1 中对9至11岁的青少年进行抽样）共同构成了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“成年青少年”，并被邀请完成成人访谈。此外，“影子青少年”在12岁时被视为“成年青少年”，在获得家长同意后，他们需要完成访谈。在 Wave 4 中，从 Wave 4 时的民用、非机构化人群中随机抽取了14,098名成人、青少年和10至11岁的“影子青少年”，作为样本。该样本来自未在 Wave 1 中被选中的居住地址，并使用类似的户内抽样程序进行招募。这个“补充样本”与 Wave 4 成人和青少年受访者结合，这些受访者来自 Wave 1 队列，他们在 Wave 4 时属于民用、非机构化人群。这总共52,731名参与者的组合构成了 Wave 4 队列。请参阅公共使用文件用户指南，以获取有关被指定为“影子青少年”的儿童以及 Wave 1 和 Wave 4 队列形成的更多详细信息。Wave 4.5 是专门针对 Wave 4.5 访谈时年龄在12至17岁之间的青少年进行的数据收集。Wave 4.5 是 Wave 1 队列成员的第四次年度后续波次。对于在 Wave 4 中被抽样的参与者，Wave 4.5 是他们的第一次年度后续波次。Dataset 0001（DS0001）包含来自（公共使用）主链接文件的（public-use）数据。此文件包含18个变量和67,276个案例。该文件提供了每个参与者的唯一识别号码以及他们在每个波次中的受访者类型的主列表，始于 Wave 1。Dataset 1002（DS1002）包含 Wave 4.5 青少年（及家长）问卷的数据。此文件包含1,395个变量和13,131个案例。Dataset 1112、1212、1222（DS1112、DS1212 和 DS1222）是包含 Wave 4.5 权重变量的数据文件。包含所有波次权重的“all-waves”权重文件包含在 Wave 1 队列中完成 Wave 4.5 青少年访谈且在 Wave 1、2、3 和 4 中完成访谈（如果年龄足够）或通过研究验证其信息（如果年龄不够接受访谈）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，无论他们在中间波次中是否参与。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。
