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 people who use or do not use tobacco.
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.
At Wave 7, a probability sample of 14,863 adults, youth, and shadow youth ages 9 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 7. This sample was recruited from residential addresses not selected for Wave 1 or Wave 4 in the same sampled PSUs and segments using similar within-household sampling procedures. This "second replenishment sample" was combined for estimation and analysis purposes with the Wave 7 adult and youth respondents from the Wave 4 Cohorts who were at least age 15 and in the civilian, noninstitutionalized population at the time of Wave 7 participants, 46,169 participants in total, forms the Wave 7 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, Wave 4, and Wave 7 Cohorts.

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).

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 G 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 E 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 respondents with current and former tobacco uses.
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 6.
The 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 Restricted-Use Files User Guide provides an overview of the entire PATH Study. The guide covers topics such as sample design, data collection, weighting, response rates, analytic considerations, and programming syntax to run common statistics and link the files together. Researchers should feel free to use the information in the User Guide for their publication and the guide should be cited as follows:
The data for the PATH Study was collected and prepared by Westat. The contract number under which they performed their work for Waves 1 through 3 is HHSN271201100027C. Work for Waves 4, 5, 6, and 7 was performed under contract number HHSN271201600001C.
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:
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. People who use or do not use tobacco 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.
At Wave 7, a probability sample of 14,863 adults, youth, and shadow youth ages 9 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 7. This sample was recruited from close to 244,000 mailing addresses not selected for Wave 1 or Wave 4, in the same sampled PSUs and segments using similar within-household sampling procedures. To meet the needs for the Wave 7 youth sample and the need for a Wave 7 Cohort shadow sample, the address sample was randomly divided into three subsamples. A subset of about 111,500 addresses (or close to 45 percent) were screened solely to identify youth ages 9 to 14; another subset of about 97,000 addresses (or close to 40 percent) were screened to identify youth ages 9 to 17. The remaining addresses (close to 36,000) were screened for adults, youth, and shadow youth ages 9 to 11. These subsamples are referred to as the "YYO" (young youth only ages 9 to 14), "YO" (youth only ages 9 to 17) and "AYS" (adults ages 18 and above, youth ages 12 to 17, and shadow youth ages 9 to 11) replenishment samples, respectively. This replenishment sample was combined for estimation and analysis purposes with Wave 7 adult and youth respondents from the Wave 1 and Wave 4 Cohorts who were at least age 15 and in the civilian,and, in the civilian, noninstitutionalized population at the time of Wave 7. This combined set of Wave 7 participants, 46,169 participants in total, forms the Wave 7 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. Data collection for Wave 7 began with both telephone and in-person interviews. In addition, a pilot test was conducted to evaluate the feasibility of introducing Web versions of the PATH Study interviews. A sample of continuing adults, parents, and youth was selected to complete the Wave 7 data collection via the Web. Wave 7 data were collected with a mix of telephone, Web, and in-person interviews.
A $2 incentive was mailed to all addresses sampled at Wave 1 and Wave 4 prior to screening. At Wave 7, a $2 incentive was mailed to all addresses in the AYS portion of the replenishment sample. Addresses in the YYO and YO portions of the replenishment sample were prepaid a $5 incentive along with invitation to complete the pre-screener on the Web, and an offer of an additional $5 for completing the online survey. All households that completed the pre-screener received the completion incentive: $5 if the pre-screener was returned via mail or if it was returned via the Web before the nonresponse follow-up mailing; $10 if the pre-screener was returned via the Web after the nonresponse follow-up mailing.
Adult respondents were paid $35 for their participation in Wave 1, Wave 2, Wave 3, and Wave 4. In Wave 5, Wave 6, and Wave 7, 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, Wave 6, and Wave 7, youth were paid $35 to complete the Youth Interview, and their parents were given $15 for each Parent Interview.
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.
People who use or do not use tobacco products in the civilian, non-institutionalized household population of the United States aged 9 and older at the time of Wave 1 (Wave 1 Cohort); People who use or do not use tobacco products in the civilian, non-institutionalized household population of the United States aged 10 and older at the time of Wave 4 (Wave 4 Cohort); People who use or do not use tobacco products in the civilian, non-institutionalized household population of the United States aged 9 or older at the time of Wave 7 (Wave 7 Cohort)
In Wave 1, Wave 2, Wave 3, Wave 4, Wave 5, Wave 6 and Wave 7 adults and youth were asked about the following types of tobacco products:
Although each section on tobacco products has some unique questions, most questions fit into one of the following categories:
Additional topics, in at least one wave, include:
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.
The weighted response rates for the Wave 1 Cohort of the PATH Study are shown below. The Wave 1 interview rates are conditional on completion of the Wave 1 screener. The response rates for Waves 2, 3, 4, 5, and 6 are conditional on Wave 1 participation.

2015-12-19 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
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 weights for Wave 4 are in three sets of files corresponding to the Wave 1 and Wave 4 Cohorts and different weight types:
The weights for Wave 5 are in five sets of files corresponding to the Wave 1 and Wave 4 Cohorts and different weight types:
The weights for Wave 6 are in six sets of files corresponding to the Wave 1 and Wave 4 Cohorts and different weight types:
The weights for Wave 7 are in seven sets of files corresponding to the Wave 1, Wave 4, and Wave 7 Cohorts and different weight types:
For each weight mentioned above, there are also 100 replicate weights and design variables (VARPSU and VARSTRAT) for use in variance estimation. Detailed information on how these variables were created, and how and why they should be used is provided in the Restricted-Use Files User Guide.
Note that the weighting procedures adjust for oversampling of specified population groups and nonresponse. ICPSR strongly recommends that researchers read and understand the sections pertaining to weights before analyzing the data to ensure correct use of these variables.
