National Longitudinal Transition Study of Special Education Students, 1987-1991

Investigators: Stanford Research Institute, Mary Wagner, Kathy Valdes, and Associates

In 1983, the U.S. Congress mandated a national study of special education students' experiences with transition out of school and into adult life. The study was conducted to provide practitioners, policy makers, researchers, and other special education affiliates with information that describes the transition that disabled youth make from secondary school to early adulthood. It was further to identify factors that contribute to youths' effective transition from secondary school to employment, further training or education, and independent living. The Office of Special Education Programs (OSEP) of the U.S. Department of Education contracted with SRI International to develop a research design, craft and field test data collection instruments, and select a sample of students for a study that would meet the congressional mandate. In April 1987, under a separate contract, SRI began data collection for The National Longitudinal Transition Study of Special Education Students, 1987-1991 (NLTS). The sample for the NLTS involves more than 8,000 youth aged 13 or older and in grade seven or higher. This sample represents the national population of secondary special education students in the 1985-86 school year. Furthermore, the sample was drawn so that findings generalize to students in secondary special education in 1985-1986, both as a whole and separately for students in each of the 11 federal special education disability categories. Data were first gathered in 1987 (referred to as Wave 1) and again in 1990-91 (referred to as Wave 2). Therefore, youths' patterns of experiences through secondary school and into their early adult years could be charted over time. In 1989, additional data were collected in two "substudies" for particular sets of youth within the primary sample. The "school program" substudy was undertaken to examine in greater detail the experiences of youth during their entire secondary school career. To examine the experiences of youth in their first few years after secondary school, the "exiter" substudy consisted of telephone interviews regarding more than 800 youth. These youth were already out of secondary school at the time of the Wave 1 interview.

National Maternal and Infant Follow-up Health Survey, 1991

Investigators: National Center for Health Statistics

The 1991 Longitudinal Follow-up to the 1988 National Maternal and Infant Health Survey (NMIHS) was conducted by the National Center for Health Statistics. The 1991 Follow-up study examines such factors as child health status and development, the effects of low birth weight, use of federal programs, child safety, child injury, child care, pediatric care, maternal health, sociodemographic characteristics, acute and chronic illness, and health insurance. The 1988 study examined factors relating to poor pregnancy outcome, such as adequacy of prenatal care, inadequate or excessive weight gain during pregnancy, maternal health behaviors such as smoking, drinking and drug use, and pregnancy and delivery complications. The 1988 National Maternal and Infant Health Survey (NMIHS) is archived as RADIUS dataset #18-20. This dataset includes data for the 1991 Follow-up Live Birth Survey and the 1991 Follow-up Medical Provider Survey. The 1991 Follow-up Live Birth Survey includes 722 variables and 8,285 cases. The 1991 Follow-up Medical Provider Survey includes 217 variables and 99,117 medical provider contacts. Because the Provider file contains hierarchical data, the Live Birth and Provider files were not merged to create a single dataset. Live Birth and Provider files have been archived as separate datasets, RADIUS datasets #01 and #02, respectively.

National Maternal and Infant Health Survey, 1988

Investigators: National Center for Health Statistics

The 1988 National Maternal and Infant Health Survey (NMIHS) was conducted by the National Center for Health Statistics (NCHS). This study examines child health status and development, use of federal programs, child safety, child injury, child care, pediatric care, maternal health, socio-demographic characteristics, acute and chronic illness, and health insurance. Furthermore, the 1988 NMIHS examines factors related to poor pregnancy outcomes, such as adequacy of prenatal care, inadequate or excessive weight gain during pregnancy, maternal health behaviors such as smoking, drinking and drug use, and pregnancy and delivery complications. This study is a national sample of live births, fetal deaths, and infant deaths in 1988. Furthermore, this study includes a supplementary sample of Hispanic live births, fetal deaths, and infant deaths in Texas, and a supplementary sample of live births for urban American Indians. These studies assess longitudinal outcomes for mothers and children between 1988 and 1991. The 1988 NMIHS obtains information in the following substantive areas: Weeks pregnant at first prenatal visit, number of visits, access and barriers to care, source of payment for prenatal care, smoking, drinking, drug use, use of Federal programs and WIC participation Length of hospital stay, source of payment for delivery Number of admissions, outpatient visits, Center for Epidemiologic Studies Depression (CES-D) scale Gestational age and birth weight Mother's marital status, height and weight, age, education, race, and occupation-work patterns Household income one year before delivery Infant feeding practices, source of payment for infant care and health insurance, child care, illness and injuries, vaccinations, and hospitalizations.

National Pediatric Trauma Registry, 1988-1994

Investigators: Carla DiScala and Bruce M. Gans

The National Pediatric Trauma Registry (NPTR) was formed to describe pediatric trauma in terms of its etiology, methods of treatment, and functional outcomes. Centered at Tufts-New England School of Medicine, and endorsed by the American Pediatric Surgical Association, the NPTR data archived here represent 45,333 children under age 19 who were admitted to one of 66 American or Canadian trauma centers between October 1988 and December 1994. The NPTR has five aims: (1) to document causes and outcomes of pediatric trauma serious enough to require hospitalization; (2) to describe resulting impairments; (3) to assess efficacy of acute intervention; (4) to estimate needs for rehabilitation services; and (5) to identify areas for preventive intervention. The National Pediatric Trauma Registry has a unique focus on the functional status of surviving children discharged from acute care. For example, nine specific domains of individual functioning are measured and included in this dataset. These domains include vision, hearing, speech, self-feeding, bathing, dressing, walking, cognition, and behavior. Moreover, 267 variables capture the duration and sequencing of children's experience with trauma, trauma severity, treatment and treatment outcomes.

National School-based Youth Risk Behavior Survey, 2003

Investigators: Centers for Disease Control and Prevention (CDC)

The Youth Risk Behavior Surveillance System (YRBSS) is an epidemiologic surveillance system that was established by the Centers for Disease Control and Prevention (CDC) to monitor the prevalence of youth behaviors that most influence health. The 2003 national school-based Youth Risk Behavior Survey (YRBS) is one component of the YRBSS. The YRBS focuses on priority health-risk behaviors established during youth that result in the most significant mortality, morbidity, disability, and social problems during both youth and adulthood. These include: tobacco use; unhealthy dietary behaviors; inadequate physical activity; alcohol and other drug use; sexual behaviors that may result in HIV infection or other sexually transmitted diseases; unintended pregnancies; and behaviors that may result in violence and unintentional injuries, as well as overweight. The results from the YRBS will be used by CDC to (1) monitor how priority health-risk behaviors among high school students (grades 9-12) increase, decrease, or remain the same over time; (2) evaluate the impact of broad national, state, and local efforts to prevent priority health-risk behaviors; and (3) monitor progress in achieving three leading health indicators and 15 Healthy People 2010 national health objectives.

National Sexual Health Survey (NSHS), 1996

Investigators: Center for AIDS Prevention Studies (CAPS); University of California, San Francisco

The National Sexual Health survey (NSHS) obtained a probability sample of all U.S. adults 18 years and older residing in the 48 contiguous states. Among identified eligibles, 77% were interviewed and the overall cooperation rate was 65%. All respondents were interviewed by telephone from June 28,1995 to April 30, 1996 in Spanish or English using procedures to ensure anonymity and privacy and to verify study authenticity. Measures were developed to assess a wide range of HIV-related and human sexuality topics, including, but not limited to: condom attitudes, condom slips and breaks, HIV-related care-giving, HIV-testing and home testing use, STD histories, perceived risk for HIV and other STDs and optimistic bias assessments, extramarital sex, sexual development, sexual abuse and rape, sexual dysfunctions, various psychological scales (sensation-seeking, machismo), family assessments and history, health and demographics, an a detailed assessment was conducted of sexual activities with each of the respondent's sexual partners, and, in addition, demographic, geographic, and HIV/STD risk characteristics of their sexual partners were determined.

National Survey of Adolescent Males, 1988

Investigators: Freya Sonenstein, Joseph Pleck, Leighton Ku and Charles Calhoun

The overall objective of the study was to increase knowledge and understanding of the determinants of adolescent male contraceptive use. The study included a variety of measures replicated from the National Survey of Young Men, conducted by Zelnik and Kantner in 1979 (DAAPPP data set number 45), as well as a number of other measures specified by the Interpersonal-Attitudinal-Utility (IAU) model of contraceptive use adapted to male respondents. The IAU model suggests that male contraceptive use is determined by the "expected utility" of contraception, assessed by respondents' perceptions of various costs and benefits associated with contraception. Thus, particular interest is paid to questions regarding perceptions of the costs and benefits of unexpected pregnancies, contraceptive devices, and expectations of probabilities of different outcomes of sexual choices. In order to deal with the problem of over-reporting of sexual activity by adolescent males, questions about sexual activity were asked in the middle of the interview as well as in the self-administered portion. The questions in the self-administered section also included a sequence of statements describing progressively intimate behaviors and asking about the respondents' participation in these behaviors. Other data in the study include extensive questions on educational history as it relates to attendance and enrollment in parocial schools. A history of the respondent's employment over the last year is also compiled. Information regarding the family structure of the respondent's household over the last year is investigated, as well as information about the household when the respondent was aged fourteen. Finally, additional in-depth information of sexual behaviour is gathered when such behavior existed. This includes information on the characteristics of the partner(s) as well as contraceptive use. In the event of a pregnancy, respondents were also asked several questions about the outcome.

National Survey of Adolescent Males, 1988 and 1990-91

Investigators: Freya L. Sonenstein, Joseph H. Pleck, and Leighton Ku

The study's primary objective was to determine adolescent males' behaviors, education and knowledge concerning human sexuality, contraception, and sexually transmitted diseases. Respondents were surveyed in 1988 (Wave 1) and in again 1990-91 (Wave 2, which is also referred to as the Follow-up Survey of Adolescent Males). Behaviors that were examined include heterosexual and homosexual activity, condom use, and intravenous drug use. The study followed young men from adolescence, the period of initiation of sexual activity and other risk behaviors, into the beginnings of young adulthood, a time when sexual activity is often at its highest.

National Survey of Adolescent Males, New Cohort, 1995

Investigators: Freya L. Sonenstein, Leighton Ku, Joseph H. Pleck, and Charles F. Turner

The overall objective of the study was to increase knowledge and understanding of the determinants of adolescent male contraceptive use. The study included a variety of measures replicated from the National Survey of Young Men, conducted by Zelnik and Kantner in 1979 (DAAPPP data set number 45), as well as a number of other measures specified by the Interpersonal-Attitudinal-Utility (IAU) model of contraceptive use adapted to male respondents. The IAU model suggests that male contraceptive use is determined by the "expected utility" of contraception, assessed by respondents' perceptions of various costs and benefits associated with contraception. Thus, particular interest is paid to questions regarding perceptions of the costs and benefits of unexpected pregnancies, contraceptive devices, and expectations of probabilities of different outcomes of sexual choices. The survey is a nationally representative survey of teenage men, designed to increase knowledge and understanding of the determinants of adolescent male contraceptive use, sexual activity and related risk behaviors. Respondents age 15 to 19 were surveyed from February through November of 1995. The most sensitive information was gathered by a Self Administered Questionnaire (SAQ).

National Survey of Adolescent Males, Old Cohort, Waves 1-3, 1988, 1990-91, 1995

Investigators: Freya L. Sonenstein, Joseph H. Pleck, Leighton Ku and Charles F. Turner

The 1988 National Survey of Adolescent Males is a nationally representative household survey of never-married males who were 15 to 19 years old in 1988, when they were sampled. The study's primary objective was to determine adolescent males' behaviors, education and knowledge concerning human sexuality, contraception, and sexually transmitted diseases. The survey followed young men from adolescence, the period of initiation of sexual activity and other risk behaviors, into the beginning of young adulthood, a time when sexual activity is often at its highest. The 1988 sample was a nationally representative multistage stratified probability sample, drawn by the Institute for Survey Research (ISR), Temple University. Black and Hispanic males were oversampled. The original weights were created, based on probability of selection, non-response and poststratification to the 1987 Current Population Survey. In 1990-91, ISR attempted to reinterview the original sample. In 1995, Research Triangle Institute (RTI) attempted to reinterview the 1988 sample again. Among the topics covered by the survey are demographic background, sexual and contraceptive history and attitudes, knowledge and attitudes about sexually transmitted diseases,work history, pregnancy and childbearing history, and child support and childrearing practices.
