title: Version 35

description: 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 Primary Sampling Unit (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.

This data file contains 53 variables and 5,408 cases. This file contains UPC values on the packages of tobacco products used or in the possession of adult respondents at the time of Wave 6. The UPC values can be used to identify and validate the specific products used by respondents and augment the analyses of the characteristics of tobacco products used by these respondents at the time of Wave 6. 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 about the child. 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).
description: The Population Assessment of Tobacco and Health (PATH) Study is a nationally representative longitudinal cohort study on tobacco use behavior, attitudes and beliefs, and tobacco-related health outcomes among adults and youth in the United States. The study's primary objectives are to: <strong>Objective 1:</strong> Identify and explain between-person differences and within-person changes in tobacco-use patterns, including the rate and length of use by specific product type and brand, product/brand switching over time, uptake of new products, and dual- and poly-use of tobacco products (i.e., use of multiple products within the same time period and switching between multiple products). <strong>Objective 2:</strong> Identify between-person differences and within-person changes in risk perceptions regarding harmful and potentially harmful constituents, new and emerging tobacco products, filters and other design features of tobacco products, packaging, and labeling; and identify other factors that may affect use, such as social influences and individual preferences. <strong>Objective 3:</strong> Characterize the natural history of tobacco dependence, cessation, and relapse, including readiness and self-efficacy to quit, motivations for quitting, the number and length of quit attempts, and the length of abstinence related to various tobacco products. <strong>Objective 4:</strong> Update the comprehensive baseline and subsequent waves of data on tobacco-use behaviors and related health conditions, including markers of exposure and tobacco-related disease processes identified from the collection and analysis of biospecimens, to assess between-person differences and within-person changes over time in health conditions potentially related to tobacco use, particularly with use of new and different tobacco products, including modified-risk tobacco products. <strong>Objective 5:</strong> Assess associations between TCA-specific actions and tobacco-product use, risk perceptions and attitudes, use patterns, cessation outcomes, and tobacco-related intermediate endpoints (e.g., biomarkers of exposure and biomarkers related to disease). Analyses will attempt to account for other potential factors, such as demographics, local tobacco-control policies, and social, familial, and economic factors, that may influence the observed patterns. <strong>Objective 6:</strong> Assess between-person differences and within-person changes over time in attitudes, behaviors, exposure to tobacco products, and related biomarkers among and within population sub-groups identified by such characteristics as race-ethnicity, gender, and/or age, or by risk factors, such as pregnancy or co-occurring substance use or mental health disorders. <strong>Objective 7:</strong> To the extent to which sample sizes are sufficient, assess and compare samples of former and never users of tobacco products for between-person differences and within-person changes in relapse and uptake, risk perceptions, and indicators of tobacco exposure and disease processes. <strong>Objective 8:</strong> Use data from the PATH Study's baseline and follow-up waves on tobacco-use behaviors, attitudes, and related health conditions, including potential markers of exposure and related disease processes identified from the analysis of biospecimens, to screen and subsample respondents for participation in formative and/or nested studies conducted during and after the PATH Study's waves of data and biospecimen collection.
description: At Wave 1, the study sampled over 150,000 mailing addresses which, using a four-staged stratified sampling design, yielded a sample of 45,971 respondents (32,320 adults / 13,651 youth) who completed a Wave 1 interview. Tobacco users and non-users who were at least 9 years old living in a civilian, non-institutionalized setting were considered for participation during Wave 1. Youth who turn 18 by the next 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. These 53,178 participants form the Wave 1 Cohort. 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 close to 174,000 mailing addresses not selected for Wave 1, in the same sampled PSUs and segments using similar within-household sampling procedures. To meet the needs for the Wave 4 Cohort shadow sample, a randomly selected subset of the sampled addresses (115,500 or close to two-thirds of the addresses) were screened solely to identify shadow youth ages 10 to 11. The remaining addresses (close to 58,500) were screened for adults, youth, and shadow youth ages 10 to 11. These are referred to as the "SO" (shadow youth only) and "AYS" (adults, youth, and shadow youth) replenishment samples, respectively. 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. The Adult files contain a single record for every adult who completed an interview in the wave. The Youth/Parent files contain a single record of every youth who completed an interview in a given wave. Parents who provided permission for their child to complete a Youth Interview were asked to complete a brief Parent Interview that contained questions about parental supervision, school performance, and tobacco use by youth. The Parent Interview is primarily an interview about the child(ren), not the parent. Almost all youth respondents had a parent or guardian complete the Parent Interview (over 99.0 percent). 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 multiple interviews, then questions asked about him or her were only asked once and skipped in the other interview(s). The parent's responses were then duplicated for the other child or children.All data were collected through in-person interviews in Waves 1, 2, 3, 4, and 5. For the continued safety of PATH Study participants and interviewers during the COVID-19 pandemic, data collection for Wave 6 began with telephone interviews only. As conditions improved in certain parts of the country, the PATH Study began in-person interviews with participants on May 7, 2021. All in-person contacts with participants were conducted in compliance with local and state restrictions for COVID-19 mitigation. Wave 6 data were collected with a mix of telephone and in-person interviews. A $2 incentive was mailed to all addresses sampled at Wave 1 and Wave 4 prior to screening. Adult respondents were paid $35 for their participation in Wave 1, Wave 2, Wave 3, and Wave 4. In Wave 5, adult respondents were paid $50 for their participation. In Wave 1, Wave 2, Wave 3, and Wave 4, youth were paid $25 to complete the Youth Interview, and their parents were given $10 for each Parent Interview. In Wave 5, youth were paid $35 to complete the Youth Interview, and their parents were given $15 for each Parent Interview.
description: In Wave 1, Wave 2, Wave 3, Wave 4, Wave 5, and Wave 6 adults and youth were asked about the following types of tobacco products: Cigarettes E-cigarettes/Electronic nicotine products Cigars (traditional, cigarillos, filtered) Pipe tobacco Hookah Smokeless tobacco (snus pouches and other forms of smokeless tobacco) Dissolvable tobacco Bidis and kreteks (youth only)IQOS (starting in Wave 6) Although each section on tobacco products has some unique questions, most questions fit into one of the following categories: Ever use Recency of use Frequency of use Amount of use Brands used Purchase details Use of flavored products Harm and addictiveness Reasons for use Additional topics, in at least one wave, include: Poly use Nicotine dependence Packaging and health warnings Risk and harm perceptions Secondhand smoke exposure Marketing and advertising Media use Demographics Health Psychosocial and mental health Substance use Cessation Social norms Peer and family influences COVID-19 Most questions asked in the questionnaires are categorical. Other questions ask, for example, the age at which something occurred or the person's body measurements. Responses to these questions are numerical.
description: Each data file for Wave 1 and Wave 2 contains weights for use in analyses of the data from the complex PATH Study sample design. The final full-sample person-level weight for Waves 1 and 2 on the Adult file is R0#_A_PWGT, and the final full-sample person-level weight for Waves 1 and 2 on the Youth / Parent file is R0#_Y_PWGT. The weights for Wave 3 are in two sets of files: The all-waves weights files are for participants who completed a Wave 3 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 Wave 1 and in Wave 2.

The single-wave weights files are for participants completing a Wave 3 interview regardless of their participation in previous waves. The Wave 3 single-wave weight is named R03_A_SWGT for adults and R03_Y_SWGT for youth. The weights for Wave 4 are in three sets of files corresponding to the Wave 1 and Wave 4 Cohorts and different weight types: The all-waves weights files are for Wave 1 Cohort participants who completed a Wave 4 interview (if old enough to do so) or verified their information (if not old enough to be interviewed) in Waves 1, 2, and 3. The Wave 4 all-waves weight for the Wave 1 Cohort is named R04_A_A01WGT for adults and R04_Y_A01WGT for youth. The single-wave weights files are for all Wave 1 Cohort respondents who completed interviews in Wave 1 and in Wave 4. The Wave 4 single-wave weight for the Wave 1 Cohort is named R04_A_S01WGT for adults and R04_Y_S01WGT for youth.

description: A four-stage stratified area probability sample design was used in the PATH Study, with a two-phase design for sampling adults at the final stage. At the first stage, a stratified sample of geographical primary sampling units (PSUs) was selected, in which a PSU is a county or group of counties. For the second stage, within each selected PSU, smaller geographical segments were formed and then a sample of these segments was drawn. At the third stage, the sampling frame consisted of the residential addresses located in these segments. The fourth stage selected adults and youth from the sampled households identified at these addresses, with varying sampling rates for adults by age, race, and tobacco use status. Adults were sampled in two phases - Phase 1 sampling used information provided in the household screener and Phase 2 sampling used information provided by the adult in the Phase 2 screener at the beginning of the Adult instrument. Please consult the Restricted-Use Files User Guide for additional details about the sampling.

Announcements, data releases and updates, new publications, upcoming events, and other information for PATH Study data users will also be posted to the forum.Data are provided via ICPSR's Virtual Data Enclave (VDE) where researchers will work with data stored on secure ICPSR servers. Researchers will not possess actual physical copies of the data; however, they may request permission to access selected output outside the virtual environment after review by ICPSR. See the Access Notes to apply for access. Researchers are also encouraged to read the VDE Guide.The data files contain person-level (PERSONID) and household-level identification (R0#_HHID) variables allowing linkage of people within a file, between Adult and Youth/Parent files, and across waves of data collection. The values in these two variables are random and contain no direct or indirect personally identifiable information. Please review Appendix D in the Restricted-Use Files User Guide for information and programming code on linking files together. The files are sorted by the variable PERSONID.ICPSR attempted to duplicate all information contained in the questionnaires into the question text used in the codebooks. Some of the longer programming instructions were not incorporated into the question text. In these cases, the question text includes a note for the user to read the full programming instructions in the corresponding section of the questionnaire. Derived and imputed variables contain the algorithms used in the creation of these variables. Users are advised to refer to the Restricted-Use Files User Guide and annotated questionnaires when reviewing the codebooks.Some variables were withheld to limit the release of information that is a potential risk for disclosure. These variables are listed in Appendix C in the Restricted-Use Files User Guide.The Youth Interview and Parent Interview questionnaires were distinct and separate questionnaires used in data collection. However, for each wave, both instruments have been combined into a single document since the responses to these instruments are also combined into a single data file.Both the Adult and Youth questionnaires in each wave include several questions about tobacco brands and products the respondent usually uses and most recently used. For each question, a list of response options was displayed on the computer screen for the respondent to select. For many major brands and products, the displayed list included both a text label and a thumbnail image of the brand logo or product package. The displayed list was different for each of the tobacco product types with the brands and products listed being those that were known to exist for the specific tobacco product type. Because these lists are long, they are not provided in a frequency table for each variable in the codebook or in the annotated instrument. For convenience, both the Adult and Youth/Parent codebooks contain an appendix with a frequency table of the top 20 responses for each variable. The PATH Study Master Tobacco Brand and Product Code Guide is available as an Excel workbook file [Documentation.xlsx (Tobacco_Brand)]. The spreadsheets in this Excel workbook file are protected and may not be edited. However, the last spreadsheet contains filters to narrow the complete list. This spreadsheet is the master file of all brand and product responses for these questions from all waves, including any responses that were not in the list of options displayed to the respondent.The PATH Study Adult Variable Crosswalk and the PATH Study Youth Variable Crosswalk are also available as Excel workbook files. The spreadsheets in these Excel workbook files are protected and may not be edited. These crosswalk files are auxiliary files that can be used in conjunction with the annotated instruments and codebooks to quickly compare content across waves. The crosswalk files link questions across waves for each respective instrument so that users can easily identify the number of waves or time points at which data for specific questions are available for analyses.In the Wave 1 and Wave 2 Youth/Parent files, the last section of the questionnaire contains demographic and health history questions. A few of the questions were asked of all youth. However, most questions were only asked of emancipated youth. The responses to these questions for non-emancipated youth were coded as "Inapplicable". The questionnaire and codebook note which variables were asked only of emancipated youth. Conversely, in the Parent Interview section the same questions were asked of parents of all sampled youth except for the emancipated youth. In this section the cases for emancipated youth were coded as "Inapplicable". There are a small number of emancipated youth in Waves 3 and 4, but there are no individual questions asked exclusively of emancipated youth.In both the Adult and Youth/Parent data files, several groups of variables contain the word "RANDOM" in both the variable name and label. This indicates computerized randomization of the question order. These "RANDOM" variables detail the order in which the questions were asked of a particular respondent.The Wave 1 data files contain 20 variable triplets pertaining to tobacco advertising. The computer randomly selected 20 advertisements and then asked the respondents whether they had seen the ad and whether they liked the ad. The Image ID variable (_AD) identifies the advertisement that was displayed to the respondent to characterize the ad, e.g., the tobacco product and brand. However, vendors did not grant permission to publicly release the actual .jpg and .bmp files containing the images seen by respondents.Derived and imputed (if present) demographic variables (age, sex, Hispanic ethnicity, and race) are included near the end of the data file. An accompanying imputation flag variable is also included. These variables are distinguished by the variable name starting with "R0#R" and contain the word "DERIVED" or "IMPUTED" in the variable label. Imputed variables are only available on the Wave 1 and Wave 4 data files.Within the "Derived and Imputed Variables" section of the codebooks of the Adult and Youth/Parent files for Wave 1 and Wave 4 only are two geographic variables - Census Region and Census Division. For Wave 1 there are additional variables to designate urban areas and Census Block characteristics.All Adult and Youth/Parent data files contain additional derived variables. These variables can be distinguished by the variable name starting with "R0#R" and contain the word "DERIVED" in the variable label. There are several variables for each tobacco category to identify certain classes of current and former tobacco users.The Study Research Derived Variables Restricted Use Files (SRDV-RUF) are a set of auxiliary files that provide some derived variables used in tables, published papers, presentations, and other analyses that have been made public by the PATH Study through May 31,2020. The objective of the SRDV-RUF is to provide access to these derived variables for use by other researchers. The SRDV-RUF for each wave consists of two data files: one for adults and one for youth. The adult SRDV-RUF has one record for every adult interview completed in the given wave, and the youth SRDV-RUF has one record for every youth interview completed in the given wave. Each file includes a set of variables with complex derivations. For example, some variables include assumptions about the meaning of skip patterns, and others involve combining the data into standardized indexes. In addition, an SRDV-RUF Supplement is also available. The Supplement (Excel) includes descriptions and algorithms for additional derived variables used for research purposes by the PATH Study but not included in the SRDV-RUF data files. It also includes citations for published works in which these derived variables were used. The derived variables are linked to citations using ArticleID, which is present in both the codebooks and the SRDV-RUF Supplement. This Supplement is available for reference so that researchers may use the algorithms to derive variables for their own purposes. SRDV-RUF data are available for Waves 1, 2, and 3.In accordance with the study's informed consent, information is suppressed about individuals who withdrew from the PATH Study. Their information was recoded to a special missing value, designated as -97777.Consent forms provided to and signed by the respondents for the various types of interviews conducted and biological samples collected are included with Wave 1 and Wave 4 files (Informed Consent forms used for Wave 1 and the Wave 4 Informed Consent form is provided with the Wave 4 files). Participants provide consent at their initial interview and biological sample collection; consents remain in effect for all subsequent waves. Aged-up adults who responded to a Youth interview in a previous wave are re-consented as an adult at the time of their first interview. The Nonresponse Bias Analysis Report for Wave 1 details the response rates and the potential for bias from nonresponse. There are also Nonresponse Bias Analysis Reports for Wave 2, Wave 3, Wave 4, Wave 5, and Wave 6The Informed Consent Document and Nonresponse Bias Analysis Reports are specific to each wave. The same files are available as documentation for both the Adult and Youth/Parent data.The questionnaires in this collection are updated versions of the fielded questionnaires that were annotated for analytic purposes. Spanish versions are also available.The PATH Study's documentation is available for your use and may be reproduced in whole or in part without permission from NIH's National Institute on Drug Abuse or FDA's Center for Tobacco Products.
