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 primary sampling units (PSU)s 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 was 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 was 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 was the first annual follow-up wave. Wave 5.5, conducted in 2020, was a special data collection for Wave 4 Cohort youth and young adults ages 13 to 19 at the time of the Wave 5.5 interview. Also in 2020, a subsample of Wave 4 Cohort adults ages 20 and older were interviewed via the PATH Study Adult Telephone Survey (PATH-ATS). 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. Of these cases, 11,378 are continuing youth having completed a prior Youth Interview. The other 1,753 cases are "aged-up youth" having previously been sampled as "shadow youth" Datasets 1112, 1212, and 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 Federal Information Processing System (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 tobacc

PATH 研究（PATH Study）于2011年启动，旨在为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》（Family Smoking Prevention and Tobacco Control Act, TCA）所进行的监管活动提供信息。PATH 研究是由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）以及食品药品监督管理局烟草产品中心（Center for Tobacco Products, CTP）共同合作开展的项目。该研究对美国全国范围内的超过150,000个邮寄地址进行了抽样，以构建一个涵盖烟草使用者和非使用者的全国性样本。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）数据，即 Wave 1。在 Wave 1 中，这45,971名成年人和9至11岁的受试者共同构成了53,178名参与者的 Wave 1 队列。受访者被要求在每个后续波次完成一次访谈。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”，在获得家长同意后，他们被要求完成访谈。在 Wave 4 中，从 Wave 4 当时的平民、非机构化人口中，对10至11岁的14,098名成年者、青少年和“影子青少年”进行了概率抽样。该样本来自未被选为 Wave 1 的同一主要抽样单位（PSU）和段落的住宅地址，并采用了类似的户内抽样程序。这一“补充样本”与 Wave 4 队列中 Wave 1 成年人和青少年受访者结合，用于估计和分析目的，总共形成了52,731名参与者的 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 队列形成的更多详细信息。Wave 4.5 是专门针对 Wave 4 队列中12至17岁青少年进行的特殊数据收集。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 是他们首次年度后续波次。Wave 5.5，于2020年进行，是针对 Wave 4 队列中13至19岁的青少年和年轻成人进行的特殊数据收集。同样在2020年，Wave 4 队列中20岁及以上的成年人通过 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 青少年和家长问卷的数据。该文件包含1,617个变量和13,131个案例。在这些案例中，有11,378名持续参与的青少年已完成之前的青少年访谈。其余1,753个案例是“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）是包含 Wave 4.5 权重变量的数据文件。‘所有波次’权重文件包含了对 Wave 1 队列中完成 Wave 4.5 青少年访谈并在 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（如果年龄不够进行访谈）的参与者的权重。有两个单独的“单波次”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‘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）包含了 Wave 4.5 青少年和家长的州标识符数据，有5个变量和13,131个案例。州标识符数据集包括PERSONID，用于将州标识符与问卷数据链接，以及3个变量指定州（州联邦信息处理系统（FIPS）、州缩写和州的全称）。此数据集中的州标识符值代表了参与者在 Wave 4.5 时的居住州。数据集1503（DS1503）包含来自 Wave 1、Wave 2、Wave 3、Wave 4 和 Wave 4.5 问卷的回答数据，表明参与者是否曾/从未使用过各种烟草产品。
