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）所进行的监管活动提供信息。PATH 研究是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）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。该研究从美国全国范围内抽取了超过150,000个邮寄地址，以构建一个烟草使用者及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（基线波）数据，即Wave 1。这45,971名成人和在Wave 1中抽取的9至11岁的样本共同组成了53,178名构成Wave 1队列的参与者。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”，并受邀完成成人访谈。此外，“影子青少年”在12岁时被视为“成年青少年”，在获得父母同意后，他们被要求完成访谈。在Wave 4中，从Wave 4时的民用、非机构化人口中随机抽取了14,098名成人、青少年和10至11岁的“影子青少年”作为样本。此样本是从与Wave 1相同的抽样PSU和段落的住宅地址中招募的，并采用了类似的户内抽样程序。这个“补充样本”与Wave 4成人及青少年受访者结合，这些受访者来自Wave 1队列，并在Wave 4时属于民用、非机构化人口。这个结合的Wave 4参与者群体，总计52,731人，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是对那些在Wave 4.5访谈时为12至17岁的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随访波次。对于在Wave 4中抽取的样本，Wave 4.5是他们第一次年度随访波次。数据集0001（DS0001）包含了主链接文件的数据。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类型的总清单，从Wave 1开始。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。数据集1112、1212、1222（DS1112、DS1212和DS1222）是Wave 4.5的权重变量数据文件。该“全波次”权重文件包含了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（如果年龄不够被访谈）的参与者的权重。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”权重文件包含了在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”权重文件包含了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，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个变量指明州（州FIPS、州缩写和州全名）。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）包含了在Wave 1、Wave 2、Wave 3、Wave 4和Wave 4.5的问卷回答中得出的数据，这些数据表明参与者截至Wave 4.5数据收集期间是否曾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。
