California Families Project [Sacramento and Woodland, California] [Restricted-Use Files] (ICPSR 35476)
The California Families Project (CFP) is an ongoing longitudinal study of Mexican origin families in Northern California. This study uses community, school, family, and individual characteristics to examine developmental pathways that increase risk for and resilience to drug use in Mexican-origin youth. This study also examines the impact that economic disadvantage and cultural traditions have in Mexican-origin youth. The CFP includes a community-based sample of 674 families and children of Mexican origin living in Northern California, and includes annual assessments of parents and children. Participants with Mexican surnames were drawn at random from school rosters of students during the 2006-2007 and 2007-2008 school year. Data collection included multi-method assessments of a broad range of psychological, familial, scholastic, cultural, and neighborhood factors. Initiation of the research at age 10 was designed to assess the focal children before the onset of Alcohol, Tobacco, and Other Drug (ATOD) use, thus enabling the evaluation of how hypothesized risk and resilience mechanisms operate to exacerbate early onset during adolescence or help prevent its occurrence. This study includes a diversity of families that represent a wide range of incomes, education, family history, and family structures, including two-parent and single-parent families.
The accompanying data file consists of 674 family cases with each case representing a focal child and at least one parent (Two-parent: n=549, 82 percent; Single-parent: n=125, 18 percent). Of the 3,139 total variables, 839 pertain to the focal child, 1,376 correspond to the mother, and 908 items pertain to the father.
Please note: While the California Families Project is a longitudinal study, only the baseline data are currently available in this data collection.
Detroit Area Study, 1985: Life Events in Everyday Experience (ICPSR 6414)
The 1985 Detroit Area Study surveyed life events of respondents. Questions addressed alcohol and drug use, emotional state, incidents of depression and fear, stress caused by children and work, and respondent's general health. Information on the respondent's family background was also collected, with specific emphases on children, parenting, and marriage. Gender comparison questions were posed to explore in detail issues such as the benefits/responsibilities of marriage, marriage roles and careers, and division of housework tasks. The survey also included items on the respondent's financial situation, social life, social support network, and demographic characteristics such as age, race, sex, education, religion, and income.
Detroit Area Study, 1995: Social Influence on Health: Stress, Racism, and Health Protective Resources (ICPSR 3272)
This survey explored the ways in which social influences, such as stress and racism, affected health, and the impact these influences had on the respondents' outlook on life. Respondents were questioned about their health status and their exercise, smoking, sleeping, and dieting habits, as well as about diagnosed health problems and depression and their effects on daily activities. Respondents were also asked a series of questions regarding their employment status, type of job and whether it was a supervisory position, the racial makeup of their workgroup, their perceptions of their position and job, the likelihood of their finding another job, hassles experienced while at work, and whether they had any trouble balancing family and work. Another series of questions asked respondents whether they had been a victim of a serious physical attack or assault, robbery, or home burglary, if they had ever been unfairly searched, stopped, or questioned by police, why they felt they had been treated this way, and if they felt they had ever been treated unfairly by a teacher, landlord, or neighbor. Opinions were also solicited on the respondents' experience with depression and anxiety. Respondents were asked whether they felt it was possible to reach their goals, how satisfied they were with their present situation, how often they felt depressed and how long this feeling lasted, whether they lost weight or sleep due to this feeling, how this feeling of depression made them view themselves, how often and how long they were worried about things that were not likely to happen, how often they worried about non-serious things, and how they felt physically when they were anxious or depressed. Another set of questions queried respondents on alcohol and drug use. Respondents were asked how often they drank alcohol, the most they had to drink at one time, whether they had experienced any addiction to alcohol or experienced any emotional or psychological problems associated with drinking, whether they had any problem controlling their drinking, whether they had used drugs outside of a doctor's order, what types of drugs they had used, how often and in what type of situations they had used these drugs, and whether they had any addiction to the drugs. Respondents were also asked whether they had a regular doctor, whether they went to a doctor's office or clinic to seek medical attention, the last time they had gone for a checkup, how they were treated by staff at the visit, whether they trusted their doctor, the reasons why they did or did not receive medical attention, and whether they had health insurance. Respondents were also asked for their perceptions of differences between Blacks and whites, attitudes toward affirmative action with regard to employment, and their attitude toward interracial relationships. Another battery of questions queried respondents on any fears or phobias they had, such as a fear of animals, water, or visiting a doctor or dentist. Questions focused on the severity of these fears, how long they had had these fears, and how much these fears interfered in daily activities. A final set of questions gathered demographic information on respondents such as highest level of education completed, political affiliation, religious affiliation, level of religious participation, importance of religion, birth date, whether they owned their own home or rented, how much they spent on food each week, total family income for the year 1994, and the height and weight of respondents.

These surveys of 12th-grade students are part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,400 variables across the questionnaires. Drugs covered by this survey include tobacco, smokeless tobacco, alcohol, marijuana, hashish, prescription medications, over-the-counter medications, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), sedatives/barbiturates, tranquilizers, cocaine, crack cocaine, GHB (gamma hydroxybutyrate), ecstasy, methamphetamine, and heroin. Other topics include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).
Highlights for 2019:
- Change in methodology: half of the MTF schools completed in-class surveys on tablets loaded with the survey; the other half completed traditional paper-and-pencil surveys. Also see the Methodology section on this page for an overview and the codebook for details.
- Expansion and revision of the study documentation in the codebook
- New documentation available for download detailing the question adds/drops/changes to the surveys
- Availability of supplemental data sets for previously unreleased questions
Two supplemental data files (DS8 and DS9) have been included this year by the Principal Investigators. These files each include three administrative variables for year (V1), form (V3), and ID (RESPONDENT_ID) along with a few additional variables of survey questions not previously released for Form 5 (DS8) and Form 6 (DS9) between the years 2016 to 2018. These same variables are already present in the main 2019 data files for Form 5 (DS6) and Form 6 (DS7). The front section of the codebook provides details about each of the variables. There are also instructions on how to merge the supplemental data on to the main data files for the previous three years:
- 2018 data (ICPSR 37416)
- 2017 data (ICPSR 37182)
- 2016 data (ICPSR 36798)
Monitoring the Future: A Continuing Study of American Youth (12th-Grade Survey), 2020 (ICPSR 38156)
This survey of 12th-grade students is part of a series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Students are randomly assigned to complete one of six questionnaires, each with a different subset of topical questions, but all containing a set of "core" questions on demographics and drug use. There are about 1,400 variables across the questionnaires. Drugs covered by this survey include tobacco, smokeless tobacco, alcohol, marijuana, hashish, prescription medications, over-the-counter medications, LSD, hallucinogens, amphetamines (stimulants), Ritalin (methylphenidate), barbiturates (tranquilizers), cocaine, crack cocaine, GHB (gamma hydroxybutyrate), ecstasy, methamphetamine, and heroin. Other topics include attitudes toward religion, changing roles for women, educational aspirations, self-esteem, exposure to drug education, and violence and crime (both in and out of school).
Highlights for 2020:
- All students recorded their survey answers on tablets that the project brought to the schools, preloaded with the MTF surveys.
- Data collection was halted prematurely on March 15, 2020 when the University of Michigan stopped all projects that involved face-to-face data collection because of COVID-19 concerns. This resulted in a 2020 sample size about 25% the size of a regular data collection.
- Guidance for combining grades for analysis: see Appendix C of the codebook.
- Information about potential mode effects for questions on student attitudes and beliefs when comparing previous years' paper-based survey responses to the current tablet method of collection. Please see the codebook Introduction - Survey Mode section for details.
