Anki for Spanish Speakers with Aphasia, United States, 2022-2023 (ICPSR 39700)
This study aimed to address the communication needs of Spanish speakers with aphasia by helping them learn scripted sentences using open-source software. The core of learning scripted sentences is to support people with aphasia to learn daily-life sentences to participate in their communities. This study had two specific aims.
First, to develop a scripted sentence treatment repository in collaboration with stakeholders through an iterative design process. Scripted sentences were designed with and for Spanish speakers with aphasia to ensure that treatment resources were linguistically and culturally appropriate.
Second, to examine the acceptability, usability, and preliminary efficacy of scripted sentence training delivered via open-source software. Participants completed baseline, treatment, and follow-up phases (~13 sessions each), learning a set of sentences (~45 each) from the repository in a single-subject multiple baseline design. Participants and their care partners were interviewed regarding their perceptions of acceptability, usability, and preliminary efficacy. Participants also completed the Client Satisfaction Questionnaire-8 and the System Usability Scale.

These data are not available through ICPSR. To apply for access to the data please visit the China Family Panel Studies Web site.
The China Family Panel Studies (CFPS) is a nationally representative, annual longitudinal general social survey project designed to document changes in Chinese society, economy, population, education, and health. The CFPS was launched in 2010 by the the Institute of Social Science Survey (ISSS) of Peking University, China. The data were collected at the individual, family, and community levels and are targeted for use in academic research and public policy analysis. All members over age 9 in a sampled household are interviewed. These individuals constitute core members of the CFPS and follow-up of all core members of the CFPS is designed to take place on a yearly basis. CFPS focuses on the economic and non-economic well-being of the Chinese people, and covers topics such as economic activities, educational attainment, family relationships and dynamics, migration, and physical and mental health.

Early Childhood Longitudinal Study [United States]: Kindergarten Class of 1998-1999, Fifth Grade (ICPSR 4440)
The Early Childhood Longitudinal Study, Kindergarten Class of 1998-1999 (ECLS-K) focuses on children's early school experiences beginning with kindergarten through fifth grade. It is a nationally representative sample that collects information from children, their families, their teachers, and their schools. ECLS-K provides data about the effects of a wide range of family, school, community, and individual variables on children's cognitive, social, emotional, and physical development, their early learning and early performance in school, as well as their home environment, home educational practices, school environment, classroom environment, classroom curriculum, and teacher qualifications.
With a few exceptions, the fifth grade data file contains all data collected from parents, children, teachers, or schools in the base year (fall and spring), first grade (fall and spring), third grade (spring), and fifth grade (spring) data collections. To streamline the file, however, the data from the household rosters that listed all household members, their relationship to the sampled child, and selected other characteristics are not included in the file. The composite variables describing critical household roster-based information, such as the children's family structure and selected characteristics of the family members, have been retained on the file.
Specific subjects covered by the variables in this data file include parent/child gender, parent/child race, family background, socioeconomic status, household income, parents' education level, and parents' employment and marital status. Other variables include type of childcare and childcare arrangements, the child's math, science, and reading scores, the child's learning problems and autism, as well as the child's diet issues, food security, and school food service. Variables about teachers include age, race, background, qualifications, job satisfaction, their level of impact on curriculum and policy, and time spent on classroom activities and specific subjects. Other variables include diversity of classroom students, parent-teacher discussions, family participation in school events and fundraising, whether the child's school has bars on the windows and doors, fire alarms, sprinklers, and fire extinguishers, the presence of school graffiti, as well as bus/transportation issues.

Efficacy of the BrightStart! Program for Promoting Emergent Literacy Skills of PreKindergarten Children at Risk for Reading Difficulties, Ohio, 2016-2020 (ICPSR 38663)
The Nemours BrightStart! (NBS!) study was a randomized controlled trial of the Nemours BrightStart! (NBS!) program. It was implemented as a small-group intervention to promote the emergent literacy skills of prekindergarten (PreK) children at risk for reading difficulties.
In this project, the researchers studied short- and long- term impacts of NBS!, including whether it reduced the reading achievement gap. Study participants included three sequential cohorts of teachers and children, and consisted of classrooms from state and local prekindergarten programs.
Classrooms were randomly assigned to one of the three study conditions:
- NBS! teacher implemented (in which the classroom teacher provided treatment)
- NBS! community aide implemented (in which treatment was provided by a community aide)
- business-as-usual control.
The study involved 290 children with full battery of assessments (plus 281 children with a partial battery) enrolled in 98 prekindergarten classrooms. Data were collected from 2016-2020.

National Health Interview Survey, 2012 (ICPSR 36146)
The National Health Interview Survey (NHIS) is conducted annually by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention (CDC). The main objective of the NHIS is to monitor the health of the United States population through the collection and analysis of data on a broad range of health topics.
The NHIS contains many similar questions every year. The repeated items are called "core questions." Beginning with a new NHIS design in 1997, these core questions were divided into three components -- Family, Sample Adult, and Sample Child.
The 2012 NHIS data release consists of six core data files, a paradata file, the three Disability Questions Tests files, a Functioning and Disability file, and two Complementary and Alternative Medicine files. Users may see the Survey Description document for more details.
The 2012 NHIS contains the core questions, as well as enhanced questions on health care access and utilization. Supplemental topics are covered in the following questionnaires: the Family questionnaire covers subjects of food security; the Sample Adult questionnaire covers subjects of immunization, complementary and alternative medicine, non-cigarette tobacco use, voice, speech, and language; and the Sample Child questionnaire covers subjects of mental health, mental health services, immunization, complementary and alternative medicine, balance, voice, speech, and language. Along with the 2012 NHIS core data files are the Disability Questions Tests 2012 files which contain person-level data collected via a field test of six disability questions. These supplemental questions appeared on the NHIS, at the end of the Family, Sample Adult, and Sample Child Cores.
The Disability Questions Tests 2012 files are released as three separate files. A fourth disability supplement was also fielded in 2012 as part of the Sample Adult Core and is called "Adult Functioning and Disability Level."
The Adult and Child Alternative Health Supplement files were intended to expand on knowledge of alternative medical services. Questions focus on how often various types of alternative therapies are used, the associated costs, and the reasons they are used.
Lastly, the Paradata Level file contains information about the survey and data collection processes; included are data on response rates, keystrokes, interview times, and number of contact attempts.

The New Immigrant Survey Round 1 (NIS-2003-1), United States, 2003-2004 [Public and Restricted-Use Version 1] (ICPSR 38031)
The New Immigrant Survey (NIS) was a nationally representative, longitudinal study of new legal immigrants to the United States and their children. The sampling frame was based on the electronic administrative records compiled for new legal permanent residents (LPRs) by the U.S. government (via, formerly, the U.S. Immigration and Naturalization Service (INS) and now its successor agencies, the U.S. Citizenship and Immigration Services (USCIS) and the Office of Immigration Statistics (OIS)). The sample was drawn from new legal immigrants during May through November of 2003. The geographic sampling design took advantage of the natural clustering of immigrants. It included all top 85 Metropolitan Statistical Areas (MSAs) and all top 38 counties, plus a random sample of MSAs and counties. The baseline survey was conducted from June 2003 to June 2004 and yielded data on:
- 8,573 Adult Sample respondents,
- 810 sponsor-parents of the Sampled Child,
- 4,915 spouses,
- and 1,072 children aged 8-12.
Interviews were conducted in the respondents' language of choice. The Round 1 questionnaire items that were used in social-demographic-migration surveys around the world as well as the major U.S. longitudinal surveys were reviewed in order to achieve comparability. The NIS content includes the following information: demographic, health and insurance, migration history, living conditions, transfers, employment history, income, assets, social networks, religion, housing environment, and child assessment tests.

NICHD Study of Early Child Care and Youth Development: Phase I, 1991-1994 [United States] (ICPSR 21940)
The overall purpose of this study was to examine the influence of variations in early childcare histories on the psychological development of infants and toddlers from a variety of family backgrounds. This general objective was addressed through a prospective, longitudinal study of the experiences of 1,364 children and their families, which took into account the complex interactions among child characteristics and those of the human and physical environments in which the children were reared.
Research GoalsThe specific research aims were as follows:
Examining the relationship between infants' childcare arrangements (defined in terms of hours, type, quality, and stability of care and the age at which the child entered care) and children's concurrent and long-term development. Specifically, the study investigated the association between children's experiences in childcare and their social, emotional, language, and cognitive development. The social-emotional assessments included measures of attachment, independence, compliance, behavior problems, prosocial and antisocial behavior, and general competence in interacting with peers. Cognitive variables include general developmental level and problem solving skills. Language assessments incorporated measures of children's expressive and receptive communicative competence.
Examining whether the social ecology of the home moderates the effects of childcare, i.e., whether children from different home environments are differentially affected by similar childcare experiences. The study examined the moderating effects of parents' values and attitudes, psychological adjustment and mental health, stress and social support, child-rearing practices, time use, interactions with the child, the marital relationship, and family demographics.
Examining whether individual differences among children moderate the effects of infant care on child development. The study examined the moderating effects of such child characteristics as age, sex, health, birth order, and temperament.
Identify demographic and family characteristics associated with families' childcare decisions. The study examined whether specific childcare arrangements are related to the parents' social class, marital status, psychological adjustment and personality, child-rearing values and attitudes, parenting practices, stress, social support, marital relationship, and the availability of childcare in the community.
Provide a natural history of infant care in the 1990s, and help establish a baseline of data pertaining to the kinds of care being used by families. Whereas other national databases, such as those provided by the United States Census Bureau, provide static estimates of the number of children in different types of childcare, this network study supplements that knowledge with longitudinal data on successive enrollments into day care at various ages, patterns of arrangements used concurrently and over time, and the stability of arrangements during the first three years of life. One of the most valuable aspects of the collaborative study is the opportunity it provides to obtain a more complete and accurate picture of patterns of infant care used by families today. Census surveys use only gross categories of care (e.g., center vs. in-home). In this study, more fine-grained information regarding the types of centers and home-care facilities was gathered.
Examine the consequences for families of maternal employment and childcare choices. Family relationships, parental mental health, family stress, and so on, are not just inputs to child development or moderators of childcare effects, they are also outcomes. High-quality childcare may alleviate family stress and enhance parental adjustment. Low-quality childcare may add to the stress parents experience. Although the main focus in the study was on the effect of childcare on the child, the study also examined the effect of childcare on the family.
Identify demographic characteristics of childcare associated with childcare quality. Of interest to policy makers is another aspect of the study, the investigation of those regulatory characteristics that predict care of higher quality. These characteristics included the level and type of caregiver training, the size of the childcare group, the auspices of the childcare program (public/private, profit/nonprofit, independent/chain, employer-sponsored/church-based), whether the facility was licensed or unlicensed, the level of payment and fees, and whether the caregiver was a relative of the family.
309 data files were compiled for this study and are organized into 3 main groups:
Analytical Data Sets (ADS) -- The raw data were examined and composites defined by small groups of individual principal investigators according to the demographic, family, childcare, and child outcome content of the data. The psychometric and distributional qualities of the variables, along with site differences, were examined. A set of variables that were psychometrically and distributionally acceptable to be used in analytic analyses was designed to test the study hypotheses. These data files comprise Parts 1-42 of the study data material.
Supplemental Data Sets -- New and revised analysis variables as well as across-time mean scores and primary composites were produced as a supplement to the original Analytical Datasets. These data files comprise Parts 43-55 of the study data material.
Raw Data Sets -- The raw data were made available and comprise Parts 56-309 of the study data material.
A three-day summer training workshop on the SECCYD was put on by NICHD at the Inter-University Consortium for Political and Social Research in Ann Arbor, Michigan in 2010. The binder from that workshop, which includes the Powerpoint slides used during presentations, are freely available to the public as part of the study documentation.

High-quality childcare may alleviate family stress and enhance parental adjustment. Low-quality childcare may add to the stress parents experience. Although the main focus in the study was on the effect of childcare on the child, the study also examined the effect of childcare on the family.
Identify demographic characteristics of childcare associated with childcare quality. Of interest to policy makers is another aspect of the study, the investigation of those regulatory characteristics that predict care of higher quality. These characteristics included the level and type of caregiver training, the size of the childcare group, the auspices of the childcare program (public/private, profit/nonprofit, independent/chain, employer-sponsored/church-based), whether the facility was licensed or unlicensed, the level of payment and fees, and whether the caregiver was a relative of the family.
504 data files were compiled for this study and are organized into 4 main groups:
Analytical Data Sets (ADS) -- The raw data were examined and composites defined by small groups of individual principal investigators according to the demographic, family, childcare, and child outcome content of the data. The psychometric and distributional qualities of the variables along with site differences were examined. A set of variables that was psychometrically and distributionally acceptable to be used in analytic analyses was designed to test the study hypotheses. These data files comprise Parts 1-49 of the study data material.
Supplemental Data Sets -- New and revised analysis variables as well as across-time mean scores and primary composites were produced as a supplement to the original Analytical Data Sets. These data files comprise Parts 50-55 of the study data material.
Raw Census-Related Data Sets -- Files were produced using geocoded addresses for survey respondents to match block group level data from the 1990 and 2000 Censuses for investigators to create additional measures of interest from the geocoded addresses. These data files comprise Parts 56-58 of the study data material.
Raw Data Sets -- The raw data were made available and comprise Parts 59-505 of the study data material.

NICHD Study of Early Child Care and Youth Development: Phase IV, 2005-2007 [United States] (ICPSR 22361)
The overall purpose of this study was to examine the influence of variations in early childcare histories on the psychological development of infants and toddlers from a variety of family backgrounds. This general objective was addressed through a prospective, longitudinal study of the experiences of 1,364 children and their families, which took into account the complex interactions among child characteristics and those of the human and physical environments in which the children were reared.
Research GoalsThe specific research aims were as follows:
Examining the relationship between infants' childcare arrangements (defined in terms of hours, type, quality, and stability of care and the age at which the child entered care) and children's concurrent and long-term development. Specifically, the study investigated the association between children's experiences in childcare and their social, emotional, language, and cognitive development. The social-emotional assessments included measures of attachment, independence, compliance, behavior problems, prosocial and antisocial behavior, and general competence in interacting with peers. Cognitive variables include general developmental level and problem solving skills. Language assessments incorporated measures of children's expressive and receptive communicative competence.
Examining whether the social ecology of the home moderates the effects of childcare, i.e., whether children from different home environments are differentially affected by similar childcare experiences. The study examined the moderating effects of parents' values and attitudes, psychological adjustment and mental health, stress and social support, child-rearing practices, time use, interactions with the child, the marital relationship, and family demographics.
Examining whether individual differences among children moderate the effects of infant care on child development. The study examined the moderating effects of such child characteristics as age, sex, health, birth order, and temperament.
Identify demographic and family characteristics associated with families' childcare decisions. The study examined whether specific childcare arrangements are related to the parents' social class, marital status, psychological adjustment and personality, child-rearing values and attitudes, parenting practices, stress, social support, marital relationship, and the availability of childcare in the community.
Provide a natural history of infant care in the 1990s, and help establish a baseline of data pertaining to the kinds of care being used by families. Whereas other national databases, such as those provided by the United States Census Bureau, provide static estimates of the number of children in different types of childcare, this network study supplements that knowledge with longitudinal data on successive enrollments into day care at various ages, patterns of arrangements used concurrently and over time, and the stability of arrangements during the first three years of life. One of the most valuable aspects of the collaborative study is the opportunity it provides to obtain a more complete and accurate picture of patterns of infant care used by families today. Census surveys use only gross categories of care (e.g., center vs. in-home). In this study, more fine-grained information regarding the types of centers and home-care facilities was gathered.

Supporting Healthy Marriage Evaluation: Eight Sites within the United States, 2003-2013 (ICPSR 34420)
The Supporting Healthy Marriage (SHM) evaluation was launched in 2003 to develop, to implement, and to test the effectiveness of a program aimed at strengthening low-income couples' marriages as one approach for supporting stable and nurturing family environments and parents' and children's well-being. The evaluation was led by MDRC and was sponsored by the Office of Planning, Research and Evaluation in the Administration for Children and Families, United States Department of Health and Human Services.The SHM program was a voluntary yearlong marriage education program for low-income married couples who had children or were expecting a child. The program provided a series of group workshops based on structured curricula designed to enhance couples' relationships; supplemental activities to build on workshop themes; and family support services to address participation barriers, connect families with other services, and reinforce curricular themes.
The study sample consists of 6,298 couples (12,596 adult sample members) who were expecting a child or had a child under 18 years old at the time of study entry. The sample consists primarily of low-to-modest income, married couples with diverse racial and ethnic backgrounds. In each family, one child was randomly selected to be the focus of any child-related measures gathered in the data collection activities. These children ranged from pre-birth to 14 years old at the time of enrollment in the study. Follow-up interviews were conducted at 12 and 30 months after baseline data collection. More detail is provided in the study documentation.

Understanding the Fear of Street Gangs: The Importance of Community Conditions [Santa Ana, California, 1997] (ICPSR 32161)
This study was designed as an exploratory study to understand fear of gang crime among residents living in an urban area plagued by gangs. During the Summer of 1997, six focus groups were conducted in Santa Ana, California -- two in lower income neighborhoods, two in middle income neighborhoods, and two in upper income neighborhoods. After the focus groups ended, participants were asked to take disposable cameras with them and take pictures of examples of neighborhood factors that prompted them to fear gangs and then mail them back to me in a postage-paid envelope.
The research questions guiding this study were: How do the fear-of-crime perspectives apply to fear of gang crime specifically? When worrying about gang crime, do different people focus primarily on different problems (e.g., some diversity or some disorder), or do the same people think about all of these factors? Findings first showed that all four theoretical perspectives on fear of crime applied to the same people at once, rather than to different people (e.g., some being worried about racial and ethnic differences but others about disorder). Second, findings illustrated specifically how these residents connected the factors into one thought process leading to fear of gangs. Residents in these groups clearly believed that ethnic and cultural diversity, or in this case, recent "illegal" Latino immigrants, brought disorder, which in turn caused community decline and brought gangs. This thought process led to personal fear of gang-related victimization. Their beliefs about these causal connections were primarily influenced by their knowledge and observations that gangs in the area were Latino; by direct observation of area diversity disorder, and decline; and by experience living in their changing neighborhoods over time. In addition, beliefs were fueled by indirect victimization, or knowledge gained primarily through acquaintances such as neighbors and community policing officers.
