Chicago Male Drug Use and Health Survey (MSM Supplement), 2002-2003 (ICPSR 34303)

Released/updated on: 2012-08-01

Geographic coverage: United States, Chicago, Illinois

Time period: 2002-09-01--2003-01-01

In recent years, club drugs such as MDMA, Ketamine, GHB, and Rohypnol have emerged as major drugs of abuse. The national and local Chicago news media have publicized law enforcement actions and adverse health outcomes, including fatalities, related to the abuse of these substances. Media accounts and a limited body of research have identified use of these substances as prevalent in the gay male community. This prevalence coincides with recent increases in HIV seropositive incidence. There is a clear need for a more comprehensive understanding of the prevalence of club drug use in the general population, and particularly in the subgroup of sexually active gay men. Noting these research gaps and their considerable adverse public health implications, this supplemental study was designed to apply an expanded protocol developed from an earlier study conducted (Feasibility and Use of Biological Measurement in Drug Surveys; R01DA12425, SRL Study #860) to a sample of gay men in the city of Chicago (Michael Fendrich, Principal Investigator). This study evaluated whether findings regarding the feasibility and use of drug testing in drug surveys derived from general population samples are generalizable to a probability sample of 216 gay men in the city of Chicago. For this project, a supplemental module was added to the main study survey that asked detailed questions about involvement in the gay community, risky sexual activity and HIV seropositivity. The scope of biological measurement was also expanded to incorporate testing for Rohypnol and Ketamine in hair (MDMA was already being tested as part of the general sample hair screen). The dataset contains 676 variables.

Civil Union Study 2000-2002, United States (ICPSR 31241)

Released/updated on: 2014-09-26

Geographic coverage: Vermont, United States

Time period: 2000-01-01--2002-01-01

Vermont was the first state in the United States to legalize same-sex relationships in mid-2000, so that same-sex couples could have the same legal rights as heterosexual married couples at the state level. Same-sex couples came to Vermont from all over the country to legalize their relationships. During the first year that this legislation was enacted, 80 percent of civil unions were acquired by out-of-state residents. In 2002, a project was conducted that compared couples who had civil unions in Vermont during the first year of that new legislation (July 2000-June 2001) with same-sex couples in their friendship circles who had not had civil unions, and with heterosexual married siblings (Solomon, Rothblum, and Balsam, 2004; 2005). The focus was on demographic factors, length of relationship, social support from family and friends, contact with families of origin, social and political activities, degree of "outness," and division of housework, child care, and finances. This was the first study to focus on same-sex couples in legalized relationships in the United States. It was also the first study to examine same-sex couples recruited from a population instead of a convenience sample, because civil unions are a matter of public record. Results indicated very few differences between same-sex couples in civil unions and those not in civil unions, particularly for women. Women in civil unions were more "out" about their sexual orientation, and more likely to consider themselves married than were women not in civil unions. Men in civil unions were more likely to have children, joint bank accounts with their partner, mutual friends with their partner, more connection with their family of origin, and to consider themselves married. They were less likely to have seriously discussed ending their relationship than men not in civil unions (Solomon et al., 2004). In contrast, both types of same-sex couples differed from heterosexual married couples in numerous ways. Same-sex couples were in their current relationship for a shorter duration, less religious, less likely to have children, more likely to share housework and finances, and less close to their family of origin than heterosexual couples. Women in same-sex relationships were more highly educated and perceived less social support from their family of origin than heterosexual married women. Men in same-sex relationships lived in larger cities, were less monogamous and more likely to agree that non-monogamy was acceptable, and perceived more social support from their friends than heterosexual married men. It is not surprising that same-sex couples differed from heterosexual couples. Prior research on lesbians and gay men from convenience samples that compared them to (a) United States census data (e.g., Bradford and Ryan, 1988), (b) their heterosexual siblings (e.g., Rothblum, et al., 2004; Rothblum and Factor, 2001), and (c) representative national samples (e.g., Laumann, Gagnon, Michael and Michaels, 1994) have consistently indicated demographic differences. It was also not surprising that same-sex couples in civil unions were quite similar to same-sex couples not in civil unions given that the first study was conducted after the first year of the new legislation. Consequently, that study was more about who chooses to have a civil union versus those who do not. It was less about how being in a civil union changes a relationship -- for that, follow-up research is needed. Demographic variables include age, race, education, religion, sexual orientation, income, and occupation.

Time period: 2009-05-25--2009-06-17

This round of Eurobarometer surveys queried respondents on standard Eurobarometer measures such as how satisfied they were with their present life. Additional questions focused on the respondents' current living conditions as compared to five years ago, and expectations for the future, including jobs, unemployment, their financial situation, inequality, affordable energy and housing, and the economic situation in their country. Further questions centered on four major areas: (1) European employment and social policy, (2) discrimination, (3) development aid, and (4) air transport services. For the first major area, European employment and social policy, the survey focused on respondents' familiarity with the European Social Fund (ESF), past and present employers, the most valuable assets in finding a job, job training, the likelihood of finding a job if laid off, and whether the European Union (EU) has a positive or negative impact on employment and social policies. For the second major area, discrimination, respondents were asked about discrimination based on ethnic origin, gender, sexual orientation, age, religion, and disability. The survey queried respondents about the extent of discrimination in their countries, whether discrimination is more or less common compared with five years ago, their personal experiences of discrimination in the past 12 months, their level of comfort with politicians of minority backgrounds, diversity in the media and workplace, how the economic crisis may affect discrimination, and respondents' identification with minority groups. For the third major area, development aid, respondents were queried about the importance of helping people in developing countries, the Millennium Development Goals, motives for rich countries to provide aid to developing nations, the countries best positioned to help develop countries, the largest challenges facing developing nations, and the European Union's contribution to development. The final major focus of the survey concluded with questions about respondents' use of air transportation, knowledge of air passengers rights, and satisfaction and positive and negative experiences with air transport services. Demographic and other background information includes age, gender, nationality, origin of birth (personal and parental), marital status and parental relations, left-right political placement, occupation, age when stopped full-time education, household composition, religious affiliation, ownership of a fixed or a mobile telephone and other durable goods, difficulty paying bills, level in society, Internet use, minority group affiliation, type and size of locality, region of residence, and language of interview (in select countries).

Family Life and Sexual Learning, 1976 (ICPSR 7755)

Released/updated on: 2010-07-28

Geographic coverage: United States, Ohio, Cleveland

This dataset contains data from a 1976 survey of 1,484 parents of 3- to 11-year-old children living in Cleveland and Cuyahoga County, Ohio. The purpose of the study was to explore in parents and their pre-adolescent children the process of learning about sexuality and the pattern of utilization of community resources regarding sexuality in the Cleveland, Ohio area (Cuyahoga County). Parents of pre-adolescents are the unit of analysis because they were seen as both the primary source of and the best reporters of their children's sexual learning. It was also seen as politically and socially impossible to conduct this research on the children directly. Where possible, both parents in two-parent families were interviewed. The intended use of the study was to influence the design and development of new policies and programs regarding sexuality in the Cleveland area. The collection contains data covering sexual topics in six general areas: (1) psychological aspects, (2) sexual functions, (3) relationships, (4) values, (5) media issues, and (6) sex roles. Specific sexual topics include: anatomy, reproduction, menstruation, masturbation, wet dreams, intercourse, homosexuality, sex play, marriage, parenting, divorce, displays of affection, love, fidelity, virginity, pre-marital sex, nudity, pornography, venereal disease, abortion, contraception, cross-sex behavior, sex segregation, and role expectations. The collection also contains data in eight main areas of learning and communication: (1) parents' experience with sexual learning and communication in the family, (2) parents' own sexual experience and attitudes, (3) parents' perceptions of their child's sexual learning and experience, (4) parents' expectations, desires, and attitudes about their child's sexual learning and behavior, (5) sex role attitudes and behavior of parents and children, (6) need for assistance and utilization of resources for sexual learning and communication, (7) parents and family demographics, and (8) possible sources of bias.

Time period: 1972-01-01--2014-01-01

Since 1972, the General Social Survey (GSS) has been monitoring societal change and studying the growing complexity of American society. The GSS aims to gather data on contemporary American society in order to monitor and explain trends and constants in attitudes, behaviors, and attributes; to examine the structure and functioning of society in general as well as the role played by relevant subgroups; to compare the United States to other societies in order to place American society in comparative perspective and develop cross-national models of human society; and to make high-quality data easily accessible to scholars, students, policy makers, and others, with minimal cost and waiting. GSS questions include such items as national spending priorities, marijuana use, crime and punishment, race relations, quality of life, and confidence in institutions. Since 1988, the GSS has also collected data on sexual behavior including number of sex partners, frequency of intercourse, extramarital relationships, and sex with prostitutes. The 2014 GSS has modules on quality of working life, shared capitalism, wealth, work and family balance, social identity, social isolation, and civic participation. In 1985 the GSS co-founded the International Social Survey Program (ISSP). The ISSP has conducted an annual cross-national survey each year since then and has involved 58 countries and interviewed over one million respondents. The ISSP asks an identical battery of questions in all countries; the U.S. version of these questions is incorporated into the GSS. The 2014 ISSP topics are National Identity and Citizenship. Demographic variables include age, gender, race, ethnicity, education, marital status, religion, employment status, income, household structure, and whether respondents were born in the United States.

Generations: A Study of the Life and Health of LGB People in a Changing Society, United States, 2016-2019 (ICPSR 37166)

Released/updated on: 2023-01-05

Geographic coverage: United States

Time period: 2016-01-01--2017-01-01, 2017-01-01--2018-01-01, 2018-01-01--2019-01-01

The Generations study is a five-year study designed to examine health and well-being across three generations of lesbians, gay men, and bisexuals (LGB). The study explored identity, stress, health outcomes, and health care and services utilization among LGBs in three generations of adults who came of age during different historical contexts. This collection includes baseline, wave 1, and wave 2 data collected as part of the Generations study.

The study aimed to assess whether younger cohorts of LGBs differed from older cohorts in how they viewed their LGB identity and experienced stress related to prejudice and everyday forms of discrimination, as well as whether patterns of resilience differed between different LGB cohorts. Additionally, the study sought to examine how differences in stress experience affected mental health and well-being, including depressive and anxiety symptoms, substance and alcohol use, suicide ideation and behavior, and how younger LGBs utilized LGB-oriented social and health services, relative to older cohorts.

In wave 2, respondents were re-interviewed approximately one year after completion of the baseline (wave 1) survey. Only respondents who participated in the original sample of participants were surveyed at wave 2 (i.e., the enhancement oversample was not included in the longitudinal design of this study).

In wave 3, respondents were re-interviewed approximately one year after the completion of the wave 2 survey.

Demographic variables collected as part of this study include questions related to age, education, race, ethnicity, sexual identity, gender identity, income, employment, and religiosity.

Time period: 1988-01-01--2001-01-01

The purpose of this project was to establish a collection of datasets that could be used (1) to analyze the influence of partnership networks on the transmission of sexually transmitted and blood-borne infections, and (2) to examine the influence of study design on estimation of network properties and impacts. Eight studies contributed datasets to the collection.

They include:

Colorado Springs Project 90, 1988-1992
Bushwick [Brooklyn, NY] Social Factors and HIV Risk (SFHR) Study, 1991-1993
Atlanta Urban Networks Project, 1996-1999
Flagstaff Rural Network Study, 1996-1998
Atlanta Antiretroviral Adherence Study, 1998-2001
Houston Risk Networks Study, 1997-1998
Baltimore SHIELD (Self-Help in Eliminating Life-Threatening Diseases), 1997-1999
Manitoba Chlamydia Study, 1997-1998

Each study contains information on sexual, needle sharing, and/or social networks. Each dataset was harmonized to permit comparative analysis. Almost all of the studies were research projects funded by federal agency sources (e.g., United States Centers for Disease Control and the National Institutes of Health); one was funded by Canadian sources. These studies, all closed for further enrollment, provide a range of designs and study types as well as a range of transmitted diseases. This allows researchers to investigate the relative effect of personal behavior and network connections on the dynamics of disease transmission, and to explore the impact of sampling design on estimation of network properties. Respondents were asked questions about different test results such as HIV, chlamydia, syphilis and hepatitis. Demographic variables include race, ethnicity, marital status, age, and gender.

How Couples Meet and Stay Together (HCMST), Wave 1 2009, Wave 2 2010, Wave 3 2011, Wave 4 2013, Wave 5 2015, United States (ICPSR 30103)

Released/updated on: 2016-03-18

Geographic coverage: United States

How Couples Meet and Stay Together (HCMST) surveyed how Americans met their spouses and romantic partners, and compared traditional to non-traditional couples. This collection covers data that was gathered over five waves. During the first wave, respondents were asked about their relationship status, including the gender, ethnicity, and race of their current partner, as well as the level of education of their parents. They were also asked about their living arrangements with their partner, the country, state, and city the respondent and/or the respondent's partner resided in most from birth to age 16, and whether the couple attended the same high school/college/university, or grew up in the same town. Information was collected on the legal status of the relationship, the city/state where the partnership was legalized, and how many times the respondent had previously been married. Additionally, respondents were asked about how often they visited with relatives, which gender they were most attracted to, their earned income in 2008, and the length of their current relationship. Finally, respondents were asked to recall how, when, and where they met their partner, how their parents felt about their partner, and to describe the perceived quality of their relationship. The second wave followed up with respondents one year after Wave 1. Information was collected on respondents' changes, if any, in marital status, relationship status, living arrangements, and reasons for separation where applicable. The third wave followed up with respondents one year after the second wave, and collected information on respondents' relationships reported in the first two waves, again including any changes in the status of the relationship and reasons for separation. The fourth wave followed up with respondents two years after Wave 3. In addition to information on relationship status and reasons for separation, Wave 4 includes the subjective level of attractiveness for the respondent and their partner. Wave 5 collected updated data on respondents' changes, if any, in marital status, relationship status, and reasons for separation where applicable. Information about respondents' sexual orientations, sex frequencies, and attitudes towards sexual monogamy were also collected. Demographic information includes age, race/ethnicity, gender, level of education, household composition, religion, political party affiliation, and household income.

The data is being released in two parts: part one is available for public use and part two is available for restricted use. The public use data contains Waves 1-5, including the addition of nine variables collecting information such as race, household income, whether the respondent was born outside of the United States, zip code relative to rural area, and respondents' living arrangements between birth and 16 years of age. The restricted use data contains Waves 1-3, and differs from the public use data by including FIPS codes for state of marriage and state of residence, town or city where the respondent was raised, and qualitative variables revised by the Principal Investigator (Waves 1-5), consisting of respondent's answers to how they first met their partner, the quality of their relationship in their own words, why they broke up if applicable and if they have an open relationship.

National Transgender Discrimination Survey, [United States], 2008-2009 (ICPSR 37888)

Released/updated on: 2020-11-19

Geographic coverage: United States

Time period: 2008-01-01--2009-01-01

This study brings to light what is both patently obvious and far too often dismissed from the human rights agenda. Transgender and gender non-conforming people face injustice at every turn: in childhood homes, in school systems that promise to shelter and educate, in harsh and exclusionary workplaces, at the grocery store, the hotel front desk, in doctors' offices and emergency rooms, before judges and at the hands of landlords, police officers, health care workers and other service providers.

The National Gay and Lesbian Task Force and the National Center for Transgender Equality are grateful to each of the 6,450 transgender and gender non-conforming study participants who took the time and energy to answer questions about the depth and breadth of injustice in their lives. A diverse set of people, from all 50 states, the District of Columbia, Puerto Rico, Guam and the U.S. Virgin Islands, completed online or paper surveys. This tremendous gift has created the first 360-degree picture of discrimination against transgender and gender non-conforming people in the U.S. and provides critical data points for policymakers, community activists and legal advocates to confront the appalling realities documented here and press the case for equity and justice.

These data provide information on discrimination in every major area of life, including housing, employment, health and health care, education, public accommodation, family life, criminal justice and government identity documents, and demographic information such as citizenship, race, ethnicity, employment, and income. In virtually every setting, the data underscores the urgent need for policymakers and community leaders to change their business-as-usual approach and confront the devastating consequences of anti-transgender bias.

Demographic information includes race, ethnicity, gender identity, sexual orientation, education, income, U.S citizenship, household size, and relationship status.

The public-use dataset was created in an earlier version of Stata that truncated write-in responses after 244 characters. The non-truncated write-in responses, plus Q10 zip codes and the essay responses to Q70, are included in the restricted-use dataset.

Population Assessment of Tobacco and Health (PATH) Study [United States] Public-Use Files (ICPSR 36498)

Released/updated on: 2026-07-09

Geographic coverage: United States

Time period: 2013-01-01--2014-01-01, 2014-01-01--2015-01-01, 2015-01-01--2016-01-01, 2016-01-01--2018-01-01, 2018-01-01--2019-01-01, 2022-01-01--2023-01-01

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 people who use or do not use tobacco.

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 Units (PSUs) 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.

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 Wave 7 adult and youth respondents from the Wave 4 Cohort who were at least age 15 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 "special collection all-waves" weight files for the Wave 7 Cohort contain weights for participants who completed a Wave 8 interview and completed interviews (if old enough to do so) or verified their information (if not old enough to be interviewed) in Wave 7 and the special collection in Wave 7.5.

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. In all 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 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 (CNP) at the time of Wave 4. This sample was recruited from residential addresses not selected for Wave 1 in the same sampled Primary Sampling Units (PSUs) 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 CNP 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 CNP 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 Cohort who were at least age 15 and in the CNP at the time of Wave 7. This combined set of Wave 7 participants, 46,169 participants in total, forms the Wave 7 Cohort.

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 all 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 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 do and 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 (CNP) at the time of Wave 4. This sample was recruited from residential addresses not selected for Wave 1 in the same sampled Primary Sampling Units (PSUs) 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 CNP 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 CNP 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 CNP at the time of Wave 7. This combined set of Wave 7 participants, 46,169 participants in total, forms the Wave 7 Cohort.

Please refer to the Public-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.

Wave 4.5 was a special data collection for youth only who were aged 12 to 17 at the time of the Wave 4.5 interview. Wave 4.5 was the fourth annual follow-up wave for those who were members of the Wave 1 Cohort. For those who were sampled at Wave 4, Wave 4.5 was the first annual follow-up wave.

Wave 5.5, conducted in 2020, was a special data collection for Wave 4 Cohort youth and young adults ages 13 to 19 at the time of the Wave 5.5 interview. Also in 2020, a subsample of Wave 4 Cohort adults ages 20 and older were interviewed via the PATH Study Adult Telephone Survey (PATH-ATS).

Wave 7.5 was a special collection for Wave 4 and Wave 7 Cohort youth and young adults ages 12 to 22 at the time of the Wave 7.5 interview. For those who were sampled at Wave 7, Wave 7.5 was the first annual follow-up wave.
