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

The Population Assessment of Tobacco and Health (PATH) Study began originally surveying 45,971 adult and youth respondents. 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. These 45,971 individuals constitute the first (baseline) wave of data collected by this longitudinal cohort study. 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, 7,207 "shadow youth" (youth ages 9 to 11 sampled at Wave 1) are considered "aged-up youth" upon turning 12 years old when they are asked to join the study subsequent to parental consent. Please refer to the Restricted Use Files User Guide that provides further details about these children designated as "shadow youth". At each subsequent wave of data collection, the parents of sampled youth are invited to complete a short Parent Interview about his or her child(ren). Dataset 0001 (DS0001) contains the data from the Master Linkage file. This file contains 19 variables and 53,178 cases. The file provides a master list of every person's unique identification number and what type of respondent they were for each wave. Dataset 1001 (DS1001) contains the data from the Wave 1 Adult Questionnaire. This data file contains 2,011 variables and 32,320 cases. Each of the cases represents a single, completed interview. Dataset 1002 (DS1002) contains the data from the Wave 1 Youth (and Parent) Questionnaire. This file contains 1,430 variables and 13,651 cases. Dataset 2001 (DS2001) contains the data from the Wave 2 Adult Questionnaire. This data file contains 2,409 variables and 28,362 cases. Of these cases, 26,447 also completed a Wave 1 Adult Questionnaire. The other 1,915 cases are "aged-up adults" having previously completed a Wave 1 Youth Questionnaire.Dataset 2002 (DS2002) contains the data from the Wave 2 Youth (and Parent) Questionnaire. This data file contains 1,588 variables and 12,172 cases. Of these cases, 10,081 also completed a Wave 1 Youth Questionnaire. The other 2,091 cases are "aged-up youth" having previously been sampled as "shadow youth." Dataset 3001 (DS3001) contains the data from the Wave 3 Adult Questionnaire. This data file contains 2,338 variables and 28,148 cases. Of these cases, 26,241 are continuing adults having completed a prior Adult Questionnaire. The other 1,907 cases are "aged-up adults" having previously completed a Youth Questionnaire. Dataset 3002 (DS3002) contains the data from the Wave 3 Youth (and Parent) Questionnaire. This data file contains 1,484 variables and 11,814 cases. Of these cases, 9,769 are continuing youth having completed a prior Youth Interview. The other 2,045 cases are "aged-up youth" having previously been sampled as "shadow youth." The other four datasets (DS3101, DS3102, DS3201, and DS3202) are data files comprising the weight variables for Wave 3. The weight variables for Wave 1 and Wave 2 are included in the main data files. However, in Wave 3 the weight variables have been separated into individual data files for Adult and Youth Questionnaires. The "all-waves" weight files contain weights for those respondents who have completed an interview during all three waves of data collection. The "single-wave" weight files contain weights for all respondents in Wave 3 regardless of whether they completed an interview during Wave 2. Each case in an Adult data file represents a single, completed interview. Each case in a Youth data file represents one youth and his or her parent's responses about that youth. Parents who provided permission for their child to participate in a Youth interview were asked to complete a brief interview about their child. In both waves of data collection, less than 0.5 percent of the parents did not complete an interview. Most questions are asked in reference to the child. In Wave 1, about 88 percent of

《烟草与健康人口评估》（PATH）研究最初对45,971名成年人和青少年受访者进行了调查。PATH研究于2011年启动，旨在为食品药品监督管理局（FDA）根据《家庭吸烟预防与烟草控制法》（TCA）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（NIDA）、国家卫生研究院（NIH）和食品药品监督管理局（FDA）下的烟草产品中心（CTP）共同合作进行的。研究在美利坚合众国超过150,000个邮寄地址中进行抽样，以构建一个全国性的烟草使用者与非使用者样本。这45,971名个体构成了该纵向队列研究收集的第一波（基线）数据。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达到18岁的青少年被视为“成年化成人”，并被邀请完成成人访谈。此外，7,207名在第一波次中采样年龄为9至11岁的“影子青少年”，在获得父母同意后，当其年满12岁时，被视为“成年化青少年”并邀请其加入研究。请参阅关于指定为“影子青少年”的儿童的《受限使用文件用户指南》，以获取有关这些儿童的更多详细信息。在每次后续数据收集波次中，样本青少年的父母被邀请完成关于其子女的简要父母访谈。数据集0001（DS0001）包含主链接文件的数据。此文件包含19个变量和53,178个案例。该文件提供了每个人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。数据集1001（DS1001）包含第一波次成人问卷的数据。此数据文件包含2,011个变量和32,320个案例。每个案例代表一次完成的访谈。数据集1002（DS1002）包含第一波次青少年（及父母）问卷的数据。此文件包含1,430个变量和13,651个案例。数据集2001（DS2001）包含第二波次成人问卷的数据。此数据文件包含2,409个变量和28,362个案例。其中26,447个案例也完成了第一波次成人问卷。其他1,915个案例是之前已完成第一波次青少年问卷的“成年化成人”。数据集2002（DS2002）包含第二波次青少年（及父母）问卷的数据。此数据文件包含1,588个变量和12,172个案例。其中10,081个案例也完成了第一波次青少年问卷。其他2,091个案例是之前作为“影子青少年”采样的“成年化青少年”。数据集3001（DS3001）包含第三波次成人问卷的数据。此数据文件包含2,338个变量和28,148个案例。其中26,241个案例是之前已完成成人问卷的持续成人。其他1,907个案例是之前已完成青少年问卷的“成年化成人”。数据集3002（DS3002）包含第三波次青少年（及父母）问卷的数据。此数据文件包含1,484个变量和11,814个案例。其中9,769个案例是之前已完成青少年访谈的持续青少年。其他2,045个案例是之前作为“影子青少年”采样的“成年化青少年”。其他四个数据集（DS3101、DS3102、DS3201和DS3202）是包含第三波次权重变量的数据文件。第一波次和第二波次的权重变量包含在主数据文件中。然而，在第三波次中，权重变量已分别分离成成人问卷和青少年问卷的独立数据文件。包含所有波次权重的文件包含在所有三个数据收集波次中完成访谈的受访者的权重。包含单波次权重的文件包含第三波次的所有受访者，无论他们是否在第二波次中完成了访谈。成人数据文件中的每个案例代表一次完成的访谈。青少年数据文件中的每个案例代表一个青少年及其父母对该青少年的回应。允许其子女参与青少年访谈的父母被要求完成关于其子女的简要访谈。在两次数据收集波次中，不到0.5%的父母没有完成访谈。大多数问题都是针对儿童提出的。在第一波次中，大约88%的……
