Americans' Use of Time, 1985 (ICPSR 9875)

Released/updated on: 1997-11-18
Geographic coverage: United States
For this data collection, respondents were asked to record in single-day time diaries each activity they engaged in over a 24-hour period. The time diary data were gathered through three different data collection methods: mail-back, telephone, and personal interviews. Respondents were instructed to describe in the diaries when the activity began, the time the activity ended, where it occurred, and who was present when the activity took place. Demographic variables include household type, respondent's sex, marital status, age, educational level, occupation, and work hours, number of children in the household under 5 and 18 years of age, and household income. Other variables focus on total work time, total time for meals at work, total minutes at work engaged in nonwork activities, total work break in minutes, and total time traveling to and from work. Data are also provided on total time spent on meal preparation and cleanup, housecleaning, outdoor chores, laundry, ironing, clothes care, home repair, baby care, child care, shopping for food, and traveling to and from food shopping. Respondents also reported total time spent on personal care, medical care, family financial activities, and sleeping, as well as time spent attending school, classes, seminars, special interest group meetings, religious meetings, sports events, and other social activities.

Exploring Factors Influencing Family Members Connections to Incarcerated Individuals in New Jersey, 2005-2006 (ICPSR 22460)

Released/updated on: 2008-12-23
Geographic coverage: United States, New Jersey
Time period: 2005-05-01--2006-07-01
In order to develop a better understanding of the factors that influence whether a male prisoner's family stays involved in his life during incarceration, researchers conducted face-to-face interviews with inmates from two New Jersey prisons and their family members between May 2005 and July 2006. A total of 35 (25 from one prison and 10 from the other) inmates and 15 family members were interviewed, comprising 13 inmate and family dyads, 1 inmate and family triad, and an additional 21 inmate interviews. The data include variables that explore the family's relationship with the incarcerated individual in the following areas: the inmate's relationship with the family prior to the incarceration, the strain (emotional, economic, stigma) that the incarceration has placed on the family, the economic resources available to the family to maintain the inmate, the family's social support system, and the inmate's efforts to improve or rehabilitate himself while incarcerated.

This study is a secondary analysis (syntax only, no data) of Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Subject Measures, 2000-2010 (ICPSR 29961) and Research on Pathways to Desistance [Maricopa County, AZ and Philadelphia County, PA]: Calendar Data, 2000-2010 [Restricted] (ICPSR 32282).

The purpose of this study was to further existing knowledge of juvenile justice intervention and how juvenile justice intervention is related to positive outcomes during the transition to adulthood. This study examines three main aims using data from the Pathways to Desistance study, which followed a sample of serious adolescent offenders for seven years to examine the desistance process. First, trajectories of secure institutional placement for serious offenders during the study period were identified. Second, trajectories of gainful activities for serious adolescent offenders during the study period were identified. Gainful activities were defined as working or attending school. Third, factors associated with turning points in the gainful activities trajectories were explored. In the course of estimating the gainful activities trajectories, there appeared to be a key moment, around year 3, where multiple trajectories with moderate levels of engagement in gainful activities diverged. Together, these three aims will inform how juvenile justice intervention is related to positive outcomes during the transition to adulthood and identify factors that may be related to positive outcomes and critical turning points in the trajectories of serious adolescent offenders.

Group differences were examined by testing bivariate differences in a broad range of variables: demographic variables (gender, age, and race/ethnicity); study site and year of interview; characteristics of prior service receipt at baseline (location and orientation); school, family and neighborhood characteristics; characteristics of the offense and offense history; individual factors (mental health and substance use symptoms); and risk scores.

Intergenerational Study of Parents and Children, 1962-1993: [Detroit] (ICPSR 9902)

Released/updated on: 2005-11-04
Geographic coverage: Detroit, United States, Michigan
Time period: 1962-01-01--1993-01-01
This data collection provides information on family formation and dissolution among young adults. Families who had given birth to their first, second, or fourth child in 1961 comprised the group of Detroit-area Caucasian couples who were interviewed and surveyed over the period 1962-1993. The resulting longitudinal study encompasses seven waves of data collected from mothers across the entire span of their offspring's childhood. Included are demographic, social, and economic information about the parental family, information about the attitudes, values, and behavior of both the mother and the father, and information about the mother's desires and expectations for her child's education, career attainments, and marriage. The collection also offers three waves of interview data collected from the children at ages 18 through 23. These data describe the young adults' attitudes and values, their expectations for school, work, marriage, and childbearing, and their perceptions of their parents' willingness to be of assistance to them. Life history calendar files for 1985 and 1993 detail the young adults' periods of cohabitation, marriage, separation, divorce, childbearing, living arrangements, education, paid employment, and military service.

Monitoring the Future: A Continuing Study of American Youth (12th-Grade Survey), 1995 (ICPSR 6716)

Released/updated on: 2007-09-07
Geographic coverage: United States
This is the 21st annual survey in this series that explores changes in important values, behaviors, and lifestyle orientations of contemporary American youth. Two general types of tasks may be distinguished. The first is to provide a systematic and accurate description of the youth population of interest in a given year, and to quantify the direction and rate of change occurring over time. The second task, more analytic than descriptive, involves the explanation of the relationships and trends observed. Each year, a large, nationally representative sample of high school seniors in the United States is asked to respond to approximately 100 drug-use and demographic questions as well as to an average of 200 additional questions on a variety of subjects, including attitudes toward government, social institutions, race relations, changing roles for women, educational aspirations, occupational aims, and marital and family plans. The students are randomly assigned 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.

Project on Human Development in Chicago Neighborhoods (PHDCN): Family Environment Scale, Wave 1, 1994-1995 (ICPSR 13590)

Released/updated on: 2006-03-01
Geographic coverage: United States, Chicago, Illinois
Time period: 1994-01-01--1997-01-01
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 these measures was the Family Environment Scale (FES). The FES was designed to assess the interpersonal relationships and the overall social environment within the family. The FES captures the perception of the family's functioning from one of its own members. In the case of the PHDCN Longitudinal Cohort Study, the respondents who completed the FES were the primary caregivers for cohorts 0-15 and the subjects composing cohort 18. The FES specifically sought to quantify three dimensions of the family environment: interpersonal relationships, directions of personal growth, and basic organization and structure. In addition to acting as a self-report measuring the family environment, the FES was also used as an instrument to observe the effect of the family environment on the individual subjects. Three scales (Conflict, Control, and Moral-Religious Emphasis) from the Family Environment Scale were used in this questionnaire to further evaluate the functioning of the family.

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).

  • Academic Achievement
  • Antisocial Activity
  • Community-Based Services
  • Contact With the Justice System
  • Court Monitoring
  • Gainful Activity
  • Head Injury
  • Living Situation
  • Making and Spending Money

Each topical domain contains multiple reference periods for looking at the topic across the entire data collection period of the study.

Users who request these restricted data should first review the documentation available from NAHDAP (user guide and frequency codebooks) and from the Pathways Website (domain content codebooks). This review will help determine which specific datasets will be needed for your project. The "Research Description" in ICPSR's Data Access Request System (IDARS) must include a specific explanation of why you need each topic domain selected on the "Data Selection" page in IDARS. Most projects should only require one reference period per topic domain being requested. Data requests for all reference periods within a given domain will not be approved without a satisfactory explanation of why all of the reference periods are required for your project. Since the Calendar data collection is very extensive and Restricted Data Use Agreements are only for 2 years, data requests are not expected to need the entire Calendar data collection.

The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales between the years 2000 and 2010. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654) and Philadelphia County, Pennsylvania (N=700).

Respondents were enrolled and baseline interviews conducted from November 2000 to January 2003. Follow-up interviews were then scheduled with the respondents at 6, 12, 18, 24, 30, 36, 48, 60, 72 and 84 months past their baseline interview.

The enrolled youth were at least 14 years old and under 18 years old at the time of their committing offense and were found guilty of a serious offense (predominantly felonies, with a few exceptions for some misdemeanor property offenses, sexual assault, or weapons offenses).

Time period: 2000-01-01--2003-01-01, 2001-01-01--2006-01-01

The Pathways to Desistance study was a multi-site study that followed 1,354 serious juvenile offenders from adolescence to young adulthood in two locales. Enrolled into the study were adjudicated youths from the juvenile and adult court systems in Maricopa County (Phoenix), Arizona (N=654) and Philadelphia County, Pennsylvania (N=700) from 2000 through 2010.

This study looks at interviews conducted with the collateral informants who participated in the study. The collateral informants were nominated by the main study participant and represented individuals who "knew the study participant well". At the interview baseline the collateral informant was usually a biological parent. During the three follow-up interviews the majority of collaterals were a friend. Collateral informants could also be a sibling, significant other, or relative. Collaterals were asked questions in regards to the main study participant's life, allowing for comparison between responses provided by two sources. A baseline interview was conducted with the collateral after the baseline interview took place with the main participant. Additional waves of follow-up with collaterals took place at 12, 24, and 36 months. A collateral report is not present for all of the main study participant interviews across waves (see response rate below).
