The Monitoring the Future (MTF) project is a long-term epidemiologic and etiologic study of substance use among youth and adults in the United States. It is conducted at the University of Michigan's Institute for Social Research and is funded by a series of investigator-initiated research grants from the National Institute on Drug Abuse.

The MTF panel study consists of six different survey forms (five forms from 1976-1988), and each survey contains a "core" set of questions about demographics and substance use. This study contains the "core" data for these questions compiled across all survey forms and years in which they are included for the longitudinal panel participants. Each record in the core panel dataset includes the respondent's data for their base year (BY) 12th grade survey (modal age 18) and their young adult follow-up FU surveys (modal ages 19-30).

The core panel dataset should be selected by all researchers. Use the linking variable available on all datasets, MTFID, to link the core dataset with all other MTF panel datasets.

The Monitoring the Future (MTF) project is a long-term epidemiologic and etiologic study of substance use among youth and adults in the United States. It is conducted at the University of Michigan's Institute for Social Research, and funded by a series of investigator-initiated research grants from the National Institute on Drug Abuse. MTF has two components: MTF Main and MTF Panel.

From its inception in 1975, the cross-sectional MTF Main study has collected data annually from nationally representative samples of 12,000-19,000 high school seniors in 12th grade located in approximately 135 schools nationwide. Beginning in 1991, similar annual cross-sectional surveys of nationally representative samples of 8th and 10th graders have been conducted. In all, approximately 45,000 students annually respond to about 100 drug use and demographic questions, as well as to about 200 additional questions divided among multiple survey forms on other topics such as attitudes toward government, social institutions, race relations, changing gender roles, educational aspirations, occupational aims, and marital plans.

The longitudinal MTF Panel study conducts follow-up surveys with representative subsamples of respondents from each 12th grade cohort participating in MTF Main. From each cohort, a sample of about 2,450 students are selected for longitudinal follow-up, with an oversampling of students who reported prior drug use during their 12th grade survey. Longitudinal follow-up currently spans modal ages 19-30 and 35-60. For surveys at modal ages 19-30, the sample is randomly split into two halves (approx. 1,225 each) to be followed every other year. One half-sample begins its first follow-up the year after high school (at modal age 19), and the other half-sample begins its first follow-up in the second year after high school (at modal age 20). Thus, six young adult follow-up (FU) surveys occur between modal ages 19-30, at modal ages 19/20 (FU1), 21/22 (FU2), 23/24 (FU3), 25/26 (FU4), 27/28 (FU5), and 29/30 (FU6). After age 30, respondents are surveyed every five years: 35, 40, 45, 50, 55, and 60 (these are referred to as FZ surveys). The FZ surveys cover many of the same topics as the 12th grade and FU surveys and include additional questions on life events and health.

MTF Panel surveys for the young adults (ages 19-30) were conducted using mailed paper surveys from 1977-2017. In 2018 and 2019, a random half of all those aged 19-30 received a mailed paper survey, while the other half were surveyed using a new procedure that encouraged participation using web surveys (web-push). The FZ surveys (ages 35-60) were conducted using mailed paper surveys through the 2019 data collection.

The National Institute on Drug Abuse (NIDA) funded RADAR in 2014 to collect multilevel, longitudinal data and biospecimens from an ethnically and racially diverse cohort of young, sexual and gender minorities (SGM; e.g., men who have sex with men (MSM), transgender women, gender non-conforming individuals) who were assigned male at birth (AMAB) (current core cohort n=1,113). The primary objective of this study is to apply a multilevel perspective to a syndemic of health issues associated with human immunodeficiency virus (HIV) in this population. The multilevel design focuses on individual, dyadic (i.e., sexual and romantic relationships), network (i.e., social, drug, and sexual connections) and biologic factors that may be associated with HIV. The cohort contains both HIV-negative and HIV-positive individuals, which allows for the development of a repository of biospecimens and HIV sequence data from both pre-infection and post-infection visits that will help facilitate future projects evaluating substance use, HIV risk, and pathogenesis.

A multiple cohort, accelerated longitudinal design was utilized by initially enrolling two existing SGM cohorts and then expanded through the use of convenience and snowball sampling methods. Enrollment criteria varied slightly based on the recruitment method, but overall inclusion criteria required participants to be AMAB, between 16 and 29 years of age, report having had sex with a man in the prior year or identify as a SGM, live in the Chicago metropolitan area, and be an English speaker. Study recruitment opened in February 2015. Participants are followed through the developmental period of late adolescence to early adulthood, which is a critical period of initiation and acceleration of sexual behavior and substance use. Study visits occur every six months.

The National Survey on Drug Use and Health (NSDUH) series (formerly titled National Household Survey on Drug Abuse) primarily measures the prevalence and correlates of drug use in the United States. Detailed NSDUH 2008 documentation is available from SAMHSA. The surveys are designed to provide quarterly, as well as annual, estimates. Information is provided on the use of illicit drugs, alcohol, and tobacco among members of United States households aged 12 and older. Questions included age at first use as well as lifetime, annual, and past-month usage for the following drug classes: marijuana, cocaine (and crack), hallucinogens, heroin, inhalants, alcohol, tobacco, and nonmedical use of prescription drugs, including pain relievers, tranquilizers, stimulants, and sedatives. The survey covered substance abuse treatment history and perceived need for treatment, and included questions from the Diagnostic and Statistical Manual (DSM) of Mental Disorders that allow diagnostic criteria to be applied. The survey included questions concerning treatment for both substance abuse and mental health related disorders. Respondents were also asked about personal and family income sources and amounts, health care access and coverage, illegal activities and arrest record, problems resulting from the use of drugs, and needle-sharing. Questions introduced in previous administrations were retained in the 2008 survey, including questions asked only of respondents aged 12 to 17. These "youth experiences" items covered a variety of topics, such as neighborhood environment, illegal activities, drug use by friends, social support, extracurricular activities, exposure to substance abuse prevention and education programs, and perceived adult attitudes toward drug use and activities such as school work. Several measures focused on prevention-related themes in this section. Also retained were questions on mental health and access to care, perceived risk of using drugs, perceived availability of drugs, driving and personal behavior, and cigar smoking. Questions on the tobacco brand used most often were introduced with the 1999 survey. For this 2008 survey, Adult mental health questions were added to measure symptoms of psychological distress in the worst period of distress that a person experienced in the past 30 days and suicidal ideation. A split-sample design also was included to administer separate sets of questions to assess impairment due to mental health problems. Background information includes gender, race, age, ethnicity, marital status, educational level, job status, veteran status, and current household composition.

The Survey of Consumer Attitudes and Behavior series (also known as the Surveys of Consumers) was undertaken to measure changes in consumer attitudes and expectations, to understand why such changes occur, and to evaluate how they relate to consumer decisions to save, borrow, or make discretionary purchases. The data regularly include the Index of Consumer Sentiment, the Index of Current Economic Conditions, and the Index of Consumer Expectations.

This survey was undertaken to assess consumer sentiment and buying plans, as well as to provide information on their savings and investment habits and perceptions of government. Open-ended questions were asked concerning evaluations and expectations about personal finances, employment, recession, price changes, and the national business situation. Additional variables probe respondents' buying intentions for a house, automobiles, appliances, and other consumer durables, and respondents' appraisals of present market conditions for purchasing houses and other durables. Other variables probe respondents' assessments of their financial status relative to the previous year, their views of the government in Washington, the need for governmental changes, military spending, government support for Black people, and their satisfaction with their income and their jobs, as well as their opinion of married women working outside the home, women's liberation, and penalties for marijuana use.

The DC Metropolitan Area Drug Study (DC*MADS) was conducted in 1991, and included special analyses of homeless and transient populations and of women delivering live births in the DC hospitals. DC*MADS was undertaken to assess the full extent of the drug problem in one metropolitan area. The study was comprised of 16 separate studies that focused on different sub-groups, many of which are typically not included or are underrepresented in household surveys.

The Homeless and Transient Population study examines the prevalence of illicit drug, alcohol, and tobacco use among members of the homeless and transient population aged 12 and older in the Washington, DC, Metropolitan Statistical Area (DC MSA). The sample frame included respondents from shelters, soup kitchens and food banks, major cluster encampments, and literally homeless people. Data from the questionnaires include history of homelessness, living arrangements and population movement, tobacco, drug, and alcohol use, consequences of use, treatment history, illegal behavior and arrest, emergency room treatment and hospital stays, physical and mental health, pregnancy, insurance, employment and finances, and demographics. Drug specific data include age at first use, route of administration, needle use, withdrawal symptoms, polysubstance use, and perceived risk.

The DC*MADS: Household and Non-household Populations examines the prevalence of tobacco, alcohol, and drug use among members of household and non-household populations aged 12 and older in the District of Columbia Metropolitan Statistical Area (DC MSA). The study also examines the characteristics of three drug-abusing sub-groups: crack-cocaine, heroin, and needle users. The household sample was drawn from the 1991 National Household Survey on Drug Abuse (NHSDA). The non-household sample was drawn from the DC*MADS Institutionalized and Homeless and Transient Population Studies. Data include demographics, needle use, needle-sharing, and use of tobacco, alcohol, cocaine, crack, inhalants, marijuana, hallucinogens, heroin, sedatives, stimulants, psychotherapeutics (non-medical use), tranquilizers, and analgesics.

The DC*MADS: Drug Use Among Women Delivering Livebirths in DC Hospitals was designed to examine the nature and extent of drug use among women delivering live births in eight Washington, DC, hospitals participating in the study. Data from the questionnaires include prenatal care, health problems during pregnancy, pregnancy drug use history, needle use, polysubstance use, patterns of use, respondent's general experiences with drug use, including perceptions of the risks and consequences of use, occurrence of psychological and emotional problems, income and insurance coverage, treatment experiences, and maternal and infant outcomes. Medical records were abstracted from the women and their infants to document medical problems. Abstracted data on the mothers included demographics, discharge diagnoses, disposition at discharge, and results of urine screens. Abstracted data on infants included delivery information, status at discharge, discharge diagnoses/procedures, and first urine toxicology screen results.
