Randomized Placebo-Controlled Trial to Assess the Impact of Oral Naltrexone on HIV Treatment Outcomes Among HIV-1 Infected Men Who Have Sex with Men and Transgender Women with Alcohol Use Disorders in Lima, Peru, 2014-2015 (ICPSR 39780)

Released/updated on: 2026-04-23
Geographic coverage: Lima, Peru
Time period: 2014-04-01--2015-12-31

The Seek, Test, Treat and Retain (STTR) Collaboration Project involved over twenty studies in the fields of HIV and drug abuse. These studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. These studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g. demographic characteristics, mental health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study. This repository contains the collected data and documentation from the STTR collaboration.

This study in particular, assesses outcomes of Oral Naltrexone on HIV Treatment among HIV-1 infected men in Lima, Peru. A randomized blinded placebo-controlled clinical trial was conducted to determine if oral naltrexone (NTX) would improve the likelihood that HIV-infected participants with alcohol use disorders (AUDs) remain engaged in care and become highly adherent to antiretroviral therapy (ART), with acceptable safety.

THE SOCIAL METACOGNITION OF MORAL JUDGMENT (ICPSR 240464)

Released/updated on: 2025-11-19
How do others’ moral judgments shape our own? Across two studies, we examined the metacognitive processes underlying judgment revision using a modified two-response paradigm. Participants gave rapid intuitive responses to sacrificial moral dilemmas, rated their confidence, and then reconsidered their judgments after viewing responses attributed to others. In Study 1, exposure to disagreement from two peers increased the likelihood of response change, reduced confidence, and promoted moderation, whereas alignment fostered more extreme judgments. In Study 2, conflict with a peer’s deliberated response carried greater weight than conflict with their intuitive response, prompting greater deliberation and judgment moderation. Across both studies, subjective confidence consistently reduced susceptibility to social influence, highlighting its role as a metacognitive anchor. The specific moral stance (deontological vs. utilitarian) did not consistently predict revision. Together, these findings demonstrate the malleability of moral intuitions, especially under conditions of low confidence and reasoned disagreement, and underscore the inherently social and dynamic nature of moral decision-making.

Oregon Youth Study Three Generational Study, Time 9, 2010-2022 (ICPSR 39048)

Released/updated on: 2025-11-12
Geographic coverage: Oregon, United States
Time period: 2010-01-01--2022-12-31

The Oregon Youth Study (OYS) tested a comprehensive model for couples from at-risk backgrounds on the basis of a dynamic developmental systems approach and stress and support processes to examine the risk and protective impacts of romantic relationships on health in adulthood. It was posited that both general and specific developmental and relationship risks have significant implications for health outcomes in mid-adulthood.

This Three Generational Study (3GS) is an intergenerational study linked to two prior studies and data sets, namely the Oregon Youth Study (OYS) which followed the fathers of the 3GS children from when they were in later childhood (aged 9-10 years) into adulthood, and the OYS-Couples study of the OYS men's relationships with women.

The Social Metacognition of moral judgment: How others’ judgments influence our own (ICPSR 190741)

Released/updated on: 2023-05-08
This project investigates the impact of others’ moral judgments on one’s judgments regarding trolley-like dilemmas. To achieve this aim, two complementary studies were conducted. In Study 1 (329 participants), we aimed to measure one’s initial moral inclination and manipulate the perceived moral competence of the “other” and the moral orientation (deontological or utilitarian) of others’ responses. To shed light on how the participant's judgment process unfolds when their initial moral intuitions conflict or accord with the moral judgments of the social source, a second Study 2 with 101 participants was designed. In this study, we use a modified version of the “two-response” paradigm that begins by assessing participants’ intuitive moral judgments accompanied by their feelings of rightness. However, before inviting participants to give the deliberated response, they were exposed to the moral judgments of two other (fictional) participants.

Self-construal and conformity (ICPSR 184271)

Released/updated on: 2023-01-25
Social influence is ubiquitous in our daily lives, influencing our opinions, beliefs, and behaviors. Individual differences may determine who is most likely to conform to the opinions of others. More specifically, individual differences in interdependent and independent self-construal determine an individual’s sensitivity to and focus on their social surroundings. Relatedly, society traditionally ascribes and prescribes different levels of agency (independence) and communion (interdependence) to men and women. Here, we examined how individual differences in self-construal, and their congruence with gender expectations, influence how people process and respond to social feedback. Results from independent behavioral and neuroimaging samples show that a stronger interdependent self-construal was associated with increased likelihood of conformity, whereas an independent self-construal was not. Further, neuroimaging data suggests that the relationship between brain activity and conformity is moderated by the congruence of gender stereotypes and self-construal. Specifically, stereotypically congruent women (with stronger interdependence) and men (with stronger independence) showed increased activity in mentalizing regions (and value regions in men) when conforming. Stereotypically incongruent women (with stronger independence) and men (with stronger interdependence) showed decreased mentalizing activity when conforming. These results shed light on underlying (neuro)psychological mechanisms that are associated with conformity among different groups.

Changing Climates of Conflict: A Social Network Experiment in 56 Schools, New Jersey, 2012-2013 (ICPSR 37070)

Released/updated on: 2020-09-14
Geographic coverage: United States, New Jersey
Time period: 2012-01-01--2013-12-31

The data in this collection are social network data drawn from a large-scale field experiment. Theories of human behavior suggest that individuals attend to the behavior of certain people in their community to understand what is socially normative and adjust their own behavior in response. This experiment tested these theories by randomizing an anti-conflict intervention across 56 New Jersey public middle schools, with 24,191 students. After having comprehensively measured every school's social network, randomly selected seed groups of 20-32 students from randomly selected schools were assigned to an intervention that encouraged public stances against conflict at school. The data allowed for comparisons between treatment and control groups, and also provided variables to analyze social networks to examine the impact of social referents.

Surveys were conducted at the start and end of the 2012-2013 school year, the year in which the experiment was conducted. The survey data contains social network variables based on the peers with whom the respondent chooses to spend time. Survey data also include respondents' perceived descriptive and prescriptive norms of conflict at the schools surveyed, as well as administrative data on the schools and demographics of respondents.

The collection includes one dataset, with 482 variables for 24,471 cases. Demographic variables in the collection include gender, grade, age, height, weight, race/ethnicity, language, household characteristics, and demographic variables obtained from school administrative records.

Processes Influencing Democratic Ownership and Participation (PIDOP) in nine European Countries, 2009-2012 (ICPSR 37137)

Released/updated on: 2019-02-12
Geographic coverage: Sweden, Czech Republic, Turkey, Belgium, Europe, England, Italy, Northern Ireland, Portugal, Germany
Time period: 2009-05-01--2012-04-30

PIDOP, Processes Influencing Democratic Ownership and Participation, was a multinational research project that was funded by the European Commission under the Seventh Framework Programme. The project examined the processes which influence democratic ownership and participation in nine European countries - Belgium, Czech Republic, England, Germany, Italy, Northern Ireland, Portugal, Sweden and Turkey. The project drew on the disciplines of Psychology, Politics, Sociology, Social Policy and Education to examine macro-level contextual factors (including historical, political, electoral, economic and policy factors), proximal social factors (including familial, educational and media factors) and psychological factors (including motivational, cognitive, attitudinal and identity factors) which facilitated and/or inhibited civic and political engagement and participation.

The project had a distinct focus on the psychology of the individual citizen and the psychological processes through which macro-level contextual factors and proximal social factors exert their effects upon citizens' civic and political engagement and participation. Young people, women, minorities and migrants were examined as four specific groups at risk of political disengagement. The research explored the differences as well as the overlap between civic and political engagement, and both direct and representative participation. The data were collected in three phases: Phase 1 (Focus Groups), Phase 2 (Individual Interviews), and Phase 3 (Quantitative Survey). Qualitative focus group and interview data are not included as part of this data collection at this time. Data included as part of this collection includes one dataset with 8197 cases for 198 variables. Demographic variables include: age, gender, ethnicity, nationality, citizenship, education-level, occupation, marital status, children, income, and political ideology.

Sloan Study of Youth and Social Development, 1992-1997 [United States] (ICPSR 4551)

Released/updated on: 2013-10-22
Geographic coverage: United States
Time period: 1992-01-01--1997-12-31
The Alfred P. Sloan Study of Youth and Social Development was designed to gather a holistic picture of the adolescent experience. To understand how young people form ideas about their future, the study considered not only what adolescents' aspirations are, but also how they may be influenced by family, peer groups, schools, and their communities. Data were collected within adolescents' three major social environments: schools, families, and peer groups. The study gathered information from 12 sites over five years, to examining such research questions as: (1) how young people of various ages and family backgrounds differ in their conceptions of work, (2) what learning opportunities families with different economic circumstances provide for their children with respect to work and careers, and (3) how schools influence educational expectations and career formation. Data were collected from focal students using the experience sampling method (ESM), an in-depth interview, and a battery of questionnaires. The questionnaires included: (1) the Teenage Life Questionnaire, a modification of instruments used in the National Educational Longitudinal Study (NELS:1988-94), (2) a Friends Sociometric form, which provided detailed information about the respondents' peer groups and social ties, and (3) the Career Orientation Survey (COS), which measures respondents' knowledge about jobs and occupational expectations. Cohort students were also administered the questionnaires but did not participate in the ESM or in-depth interviews. All instruments were administered to focal students in Years 1, 3, and 5. In addition, in Year 2, in-depth interviews alone were administered to focal students. In years 1, 3, and 5, a separate group of cohort students were administered the questionnaires. Parts 1, 2, 6, 7, 11, and 12 consist of the Teenage Life Questionnaire data. Parts 3, 4, 8, 9, 13, and 14 consist of the Career Orientation Survey data. Parts 5, 10, and 15 consist of the Experience Sampling Method data. The in-depth interview component will be released by ICPSR as restricted data at a later time.

Advogato Online Open Source Community, 2000-2001 (ICPSR 29101)

Released/updated on: 2011-03-31
Time period: 2000-02-01--2001-09-30
This study analyzed the evolution of the status hierarchy within a large-scale, natural setting. The results of empirical analyses of status ratings within a large online community of software developers showed that, in the process of status attainment, community members tended to evaluate a focal actor's reputation according to publicly available social references, such as the number and status of other evaluators. Ironically, these same social references also worked to produce constraint in an actor's status mobility. In order to manage the large amount of data, a custom-written JAVA script was used to extract the pertinent data from the XML code and then insert the data into a SQL database, from which it was possible to use standard query language to combine information from the discrete panels into a single ASCII data file.

Time period: 1999-10-15--1999-11-14
This round of Eurobarometer surveys queried respondents on standard Eurobarometer measures, such as how satisfied they were with their present life, whether they attempted to persuade others close to them to share their views on subjects they held strong opinions about, whether they discussed political matters, how important the role of the European Union (EU) will be in their daily life over the next five years, and how they viewed the need for societal change. Additional questions focused on the respondents' knowledge of and opinions on the EU, including how well-informed they felt about the EU, what sources of information about the EU they used, whether their country had benefited from being an EU member, and the extent of their personal interest in EU matters. Other major areas of focus in the surveys included European Parliament elections, the single European currency (the euro), and respondents' experiences with financial services. Respondents were asked which television news programs they watched, which newspaper(s) they read, and how much attention they gave to politics, social issues, the European Union, the economy, sports, the environment, foreign policy, and culture. They were also asked whether they voted in the most recent European Parliament elections, what their reasons were for voting or not voting, and how they viewed the importance and power of the European Parliament in the European Union. A number of questions probed for respondents' knowledge and use of the euro, whether they worried about changing to the euro, and what they thought about the timing of the change to the euro and about legislation surrounding the euro. Another set of questions queried respondents about financial services and obstacles to using those services, means of payment for important purchases, bank accounts, post office accounts, loans, and mortgages. Standard demographic information was collected on left-right political self-placement, marital status, age at completion of education, current age, sex, number of people in the household, number of children in the household, current occupation, previous occupation, household income,size of locality, and region of residence.

The Chicago Council undertakes a large-scale public opinion study every two years that compares American and international public opinion on a wide range of important international issues. A significant part of each biennial survey is additionally dedicated to examining a timely theme. The theme of the 2006 survey was, "The Rise of China and India."

This data collection presents a unique comparison of international attitudes on how the emergence of China and India as economic dynamos and claimants to great power status will affect the global economy, international security, and politics. Moreover, this study sought to assess American public opinion (Part 1, Public Opinion Survey, United States) on a variety of challenges facing the United States today including international terrorism, nuclear proliferation, conflict in the Middle East, the rising economic and political power of Asia, economic competition from abroad, and threats to energy supplies and the environment. This data collection also provides an understanding of how the Chinese (Part 2, Public Opinion Survey, China) and Indian (Part 3, Public Opinion Survey, India) publics view their nations' international challenges and opportunities and their respective roles as emerging great powers. Parallel surveys were also conducted in Australia (Part 4, Public Opinion Survey, Australia) in conjunction with the Lowy Institute for International Policy, and in South Korea (Part 5, Public Opinion Survey, South Korea) in conjunction with the East Asia Institute.

Demographic variables include race, age, gender, religious affiliation, highest level of education, and political identification.

The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One such measure was the Interviewer Impressions (Primary Caregiver). This set of questions was completed by the interviewer at the end of each interview with a primary caregiver (PC). The interviewer supplied basic demographic information and rated the behavior of the PC toward the interviewer, as well as the PC's behavior and attitude toward the subject and other household members. It was completed for Cohorts 0, 3, 6, 9, and 12 and it is closely related to PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): INTERVIEWER IMPRESSIONS (PRIMARY CAREGIVER), WAVE 2, 1997-2000 (ICPSR 13631).

Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One of the measures composing the Longitudinal Cohort Study was the Home and Life Interview. The Home and Life Interview was a restructured interview based on the Home Observation for Measurement of the Environment (HOME) inventory used in Wave 1 (PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HOME OBSERVATION FOR MEASUREMENT OF THE ENVIRONMENT, WAVE 1, 1994-1997 [ICPSR 13594]). The Home and Life Interview, like the HOME inventory, sought to observe the developmental environment in which children belonging to the Longitudinal Cohort Study sample were raised. The Home and Life Interview was designed to capture the absence or presence of certain cognitive stimuli, including varied learning experiences and diverse educational materials. The Home and Life Interview also measured the extent and nature of the interactions that occurred between the subject and his or her primary caregiver. The Wave 3 Home and Life Interview instrument was a reduced version of the Wave 2 Home and Life Interview instrument (PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): HOME AND LIFE INTERVIEW, WAVE 2, 1997-2000 [ICPSR 13630]) that does not include an emphasis on evaluating the relationship between the subject and the subject's father or, in the father's absence, a male father figure. It was administered to subjects' primary caregivers for Cohorts 0, 3, 6, and 9.

The PHDCN version of the HOME inventory also assessed the physical conditions in and around the respondent's home, taking careful note of the layout of the streets and buildings comprising the neighborhood.

Project on Human Development in Chicago Neighborhoods (PHDCN): Infant Assessment Unit, Wave 1, 1995-1997 (ICPSR 13579)

Released/updated on: 2006-02-17
Geographic coverage: United States, Chicago, Illinois
Time period: 1994-01-01--1997-12-31
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. Part of the Longitudinal Cohort Study was the Infant Assessment Unit (IAU). The objective of the IAU was to observe how prenatal and postnatal conditions affect the health and cognitive functioning of infants during the first year of life. Consisting of several instruments, the IAU sought to measure infant cognition and quantify the experiences of the sampled infants from Cohort 0 during their first 12 months of life. Additionally, the IAU examined the circumstances surrounding the mother's pregnancy and the subsequent care received by the infant.

Released/updated on: 2006-01-18
Geographic coverage: United States, New York (state)
Time period: 1948-01-01--1948-12-31
This four-wave data collection contains information on the social and psychological aspects of political behavior among voters in Elmira, New York, in 1948. In order to probe voting behavior among the electorate, information was gathered about labor unions and community organizations, social and ethnic differences, perceptions of group voting trends, the influence of family and friends, polarization between social groups, and effects of political campaigns on social groups. Respondents were asked about their party choice, voting intentions, perceived best Republican and Democratic presidential candidates, the two major electoral issues facing the country, effects of the elected president on the relations between the United States and Russia, and their voting behaviors. Other items probed respondents' feelings about price controls, big corporations, labor unions, the economy, cost of living, relations between labor and management, their community, their job, war prospects, and the Middle East crisis. Additional items queried respondents on exposure to and use of the news media, recreational and reading habits, the role of mass media in transmitting political information, and the effects of specific campaign events on voters. Demographic items specify age, education, sex, marital status, religion, occupation, social class, club memberships, family's choice of presidential candidate, veteran status, length of residence in neighborhood, and nationality.

Project on Human Development in Chicago Neighborhoods (PHDCN): Home and Life Interview, Wave 2, 1997-2000 (ICPSR 13630)

Released/updated on: 2005-12-06
Geographic coverage: United States, Chicago, Illinois
Time period: 1997-01-01--2000-12-31
The Project on Human Development in Chicago Neighborhoods (PHDCN) was a large-scale, interdisciplinary study of how families, schools, and neighborhoods affect child and adolescent development. One component of the PHDCN was the Longitudinal Cohort Study, which was a series of coordinated longitudinal studies that followed over 6,000 randomly selected children, adolescents, and young adults, and their primary caregivers over time to examine the changing circumstances of their lives, as well as the personal characteristics, that might lead them toward or away from a variety of antisocial behaviors. Numerous measures were administered to respondents to gauge various aspects of human development, including individual differences, as well as family, peer, and school influences. One of the measures composing the Longitudinal Cohort Study was the Home and Life Interview. The Home and Life Interview was a restructured interview based on the Home Observation for Measurement of the Environment (HOME) inventory used in Wave 1. The Home and Life Interview, like the HOME inventory, sought to observe the developmental environment in which children belonging to the Longitudinal Cohort Study sample were raised. The Home and Life Interview was designed to capture the absence or presence of certain cognitive stimuli, including varied learning experiences and diverse educational materials. The Home and Life Interview also measured the extent and nature of the interactions that occurred between the subject and his or her primary caregiver. In contrast to Wave 1, particular emphasis was placed on evaluating the relationship between the subject and the subject's father or, in the father's absence, a male father figure. An important feature of the Wave 1 HOME inventory was the data collected that described the interior and exterior conditions of the respondent's home and neighborhood. Similar observations were recorded, however, for Wave 2. This information was documented in the Interviewer Impressions data found in PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): INTERVIEWER IMPRESSIONS (PRIMARY CAREGIVER), WAVE 1, 1997-2000 (ICPSR 13631) and in PROJECT ON HUMAN DEVELOPMENT IN CHICAGO NEIGHBORHOODS (PHDCN): INTERVIEWER IMPRESSIONS (SUBJECT), WAVE 1, 1997-2000 (ICPSR 13632).

Geographic coverage: District of Columbia, San Diego, United States, California
Time period: 1990-01-01--1990-12-31
This data collection offers information on socioeconomic and demographic characteristics of synthetic drug users, characteristics of synthetic drug use such as frequency and method of intake, and factors that prompt drug users to begin to use synthetic drugs or to switch from agricultural drugs to synthetic drugs. Synthetic drugs investigated in the collection include PCP, ice, ecstasy, and speed, while nonsynthetic drugs include alcohol, marijuana, heroin, cocaine, and crack. Patterns of use for all of these drugs are explored. Questions about specific drugs include whether the respondent had ever used the drug, age first used, number of days in the past 30 days the drug was used, whether the drug was used more than two times per week, method of drug intake, and the drug used most often by the respondent and by the respondent's friends. Additional variables include reasons for preferring synthetic or nonsynthetic drugs, reasons the respondent would discontinue use or switch to another drug, availability and cost of certain drugs, and extent of involvement in selling, money handling, and protection. Finally, demographic variables such as sex, ethnicity, age, highest grade completed, employment activity in the past month, geographical location, and subject source (criminal justice system or drug treatment center) are included in the file. The unit of analysis is the individual drug user.

Detroit Area Study, 1995: Social Influence on Health: Stress, Racism, and Health Protective Resources (ICPSR 3272)

Released/updated on: 2002-08-16
Geographic coverage: Detroit, United States, Michigan
Time period: 1995-01-01--1995-12-31

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.
