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 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 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.Dataset 0001 (DS0001) contains the data from the Master Linkage file. This file contains 14 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. Dataset 1001 (DS1001) contains the data from the Wave 1 Adult Questionnaire. This data file contains 1,732 variables and 32,320 cases. Each of the cases represents a single, completed interview.

This file contains 1,228 variables and 13,651 cases.Dataset 2001 (DS2001) contains the data from the Wave 2 Adult Questionnaire. This data file contains 2,197 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 1,389 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 2,139 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 1,309 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." Datasets 3101, 3102, 3201 and 3202 (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 their participation in previous waves. Dataset 3503 (DS3503) contains data derived from responses to Wave 1-3 questionnaires indicating if participants had ever/never used various tobacco products as of the Wave 3 study period. This data file contains 25 variables for all 53,178 study participants as of Wave 3. This file is provided for reference only to simplify the definitions of tobacco use variables in the Adult and Youth data files for subsequent waves. Dataset 4001 (DS4001) contains the data from the Wave 4 Adult Questionnaire. This data file contains 2,182 variables and 33,822 cases. Of these cases, 25,857 are continuing adults having completed a prior Adult questionnaire, 1,900 are "aged-up adults" having previously completed a Youth questionnaire, and 6,065 are "replenishment sample adults" (also known as "new cohort adults" in the annotated instrument). Dataset 4002 (DS4002) contains the data from the Wave 4 Youth and Parent Questionnaire. This data file contains 1,389 variables and 14,798 cases. Of these cases, 9,365 are continuing youth having completed a prior Youth interview, 1,694 cases are "aged-up youth" having previously been sampled as "shadow youth," and 3,739 are "replenishment sample youth" (also known as "new cohort youth" in the annotated instrument). Datasets 4111, 4112, 4211, 4212, 4321, and 4322 (DS4111, DS4112, DS4211, DS4212, DS4321, and DS4322) are data files comprising the weight variables for Wave 4. In Wave 4, the weight variables have been separated into individual data files corresponding to the Wave 1 and Wave 4 Cohorts and different weight types. The "all-waves" weight files contain weights for those Wave 1 Cohort respondents who completed an interview for all waves in which they were old enough or verified their information for waves in which they were not old enough to be interviewed. The "single-wave" weight files contain weights for Wave 1 Cohort respondents at Wave 4 who completed an interview at Wave 1, regardless of their participation in previous waves. The "cross-sectional" weight files contain weights for all respondents in the Wave 4 Cohort. Dataset 4503 (DS4503) contains data derived from responses to Wave 1-4 questionnaires indicating if participants had ever/never used various tobacco products as of the Wave 4 data collection period. This data file contains 27 variables for all 67,276 study participants as of the Wave 4 data collection. This file is provided for reference only to simplify the definitions of tobacco use variables in the Adult and Youth data files for subsequent waves. Dataset 5001 (DS5001) contains the data from the Wave 5 Adult Questionnaire. This data file contains 2,315 variables and 34,309 cases. Of these cases, 29,876 are continuing adults having completed a prior Adult questionnaire, 4,433 are "aged-up adults" having previously completed a Youth questionnaire.Dataset 5002 (DS5002) contains the data from the Wave 5 Youth and Parent Questionnaire. This data file contains 1,530 variables and 12,098 cases. Of these cases, 10,446 are continuing youth having completed a prior Youth interview, 1,652 cases are "aged-up youth" having previously been sampled as "shadow youth."Datasets 5111, 5112, 5211, 5212, 5221, 5222, 5711, 5712, 5721, and 5722 (DS5111, DS5112, DS5211, DS5212, DS5221, DS5222, DS5711, DS5712, DS5721, and DS5722) are data files comprising the weight variables for Wave 5. In Wave 5, the weight variables are in individual data files corresponding to the Wave 1 and Wave 4 Cohorts and different weight types. The "all-waves" weight files contain weights for those Wave 1 Cohort participants who completed a Wave 5 interview and completed interviews (if old enough to do so) or verified their information (if not old enough to be interviewed) in Waves 1, 2, 3, and 4. Dataset 5503 (DS5503) contains data derived from responses to Wave 1-5 (including Wave 4.5) questionnaires indicating if participants had ever/never used various tobacco products as of the Wave 5 data collection period. This data file contains 26 variables for all 67,276 study participants as of the Wave 5 data collection. This file is provided for reference only to simplify the definitions of tobacco use variables in the Adult and Youth data files for subsequent waves.There are two separate sets of files with "single wave" weights: one for the Wave 1 Cohort and one for the Wave 4 Cohort. The "single-wave" weight files for the Wave 1 Cohort contains weights for participants who completed an interview in Wave 1 and in Wave 5, regardless of their participation in the intervening waves. The "single-wave" weight file for the Wave 4 Cohort contains weights for all Wave 5 interview respondents in the Wave 4 Cohort.There are also two separate sets of files with "special collection all-waves" weights: one for the Wave 1 Cohort and one for the Wave 4 Cohort. The "special collection all-waves" weight file for the Wave 1 Cohort contains weights for participants who completed a Wave 5 interview and completed interviews (if old enough to do so) or verified their information (if not old enough to be interviewed) in Waves 1, 2, 3, 4, and the special collection in Wave 4.5. The "special collection all-waves" weight file for the Wave 4 Cohort contains weights for participants who completed a Wave 5 interview and completed interviews (if old enough to do so) or verified their information (if not old enough to be interviewed) in Wave 4 and the special collection in Wave 4.5. 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. Across all waves of data collection, an average of 0.6 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).
