Population Assessment of Tobacco and Health (PATH) Study [United States] Public-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 FDA'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) annual 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 when they are asked to join the study subsequent to parental consent. Please refer to the 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 4 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 Interview. This data file contains 1,731 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) Interviews. This file contains 1,228 variables and 13,651 cases.Dataset 2001 (DS2001) contains the data from the Wave 2 Adult Interview. This data file contains 2,195 variables and 28,362 cases. Of these cases, 26,447 also completed a Wave 1 Adult Interview. The other 1,915 cases are "aged-up adults" having previously completed a Wave 1 Youth Interview. Dataset 2002 (DS2002) contains the data from the Wave 2 Youth Interview. This data file contains 1,389 variables and 12,172 cases. Of these cases, 10,081 also completed a Wave 1 Youth Interview. The other 2,091 cases are aged-up youth respondents having previously been flagged as "shadow youth". 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 the "parent" respondents were the biological mother or father. When multiple youth from the same household were selected to be in the study, the parent(s) completed separate interviews about each youth. If one parent completed two or more interviews that parent only answered questions about himself/herself once. Those questions were then skipped in the subsequent interview(s) for the other child(ren) and the responses duplicated in that child(ren)'s data file(s).

《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，旨在为美国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研究由美国国家药物滥用研究所（NIDA）、美国国立卫生研究院（NIH）和食品药品监督管理局（FDA）下属的烟草产品中心（CTP）联合开展。研究通过对美国超过150,000个邮寄地址进行抽样，构建了一个涵盖烟草使用者和非使用者的全国性样本。这45,971名个体构成了该纵向队列研究首次（基线）年度数据收集的样本。受访者在每个后续波次中均需完成一次访谈。在当前数据收集波次中达到18岁的青少年被视为“成年化成年人”，并被邀请完成成人访谈。此外，7,207名在第一波次（Wave 1）中抽取的9至11岁“影子青少年”（shadow youth）在12岁时，在获得父母同意后加入研究，被视为“成年化青少年”。请参阅用户指南，以获取有关这些被指定为“影子青少年”的儿童的更多详细信息。在数据收集的每个后续波次中，样本青少年父母的访谈被邀请完成，以简要了解其子女情况。数据集0001（DS0001）包含主链接文件的数据。该文件包含4个变量和53,178个案例，提供了每位受试者唯一识别号及其在每个波次中的受试者类型的主列表。数据集1001（DS1001）包含第一波次成人访谈的数据。此数据文件包含1,731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）访谈的数据。该文件包含1,228个变量和13,651个案例。数据集2001（DS2001）包含第二波次成人访谈的数据。此数据文件包含2,195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访谈，其他1,915个案例是之前已完成第一波次青少年访谈的“成年化成年人”。数据集2002（DS2002）包含第二波次青少年访谈的数据。该数据文件包含1,389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访谈，其他2,091个案例是之前已被标记为“影子青少年”的成年化青少年受访者。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关于该青少年的回应。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。在两个波次的数据收集过程中，不到0.5%的父母未完成访谈。大多数问题都是针对儿童提出的。在第一波次中，大约88%的“父母”受访者是生物学上的母亲或父亲。当同一家庭中有多名青少年被选中参与研究时，父母会分别完成关于每个青少年的访谈。如果一名父母完成了两次或更多次访谈，该父母仅对自己进行一次回答，随后访谈中关于其他儿童的问题将被跳过，并在该儿童的相应数据文件中重复该回答。
