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.

National Survey of Adolescent Males-1988 and 1990-91

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

The National Survey of Adolescent Males 1988 and 1990-91 (NSAM) is a two-wave, longitudinal study conducted between 1988 and 1991. 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. This dataset includes data from both Wave 1 (1988) and Wave 2 (1990-91) of the survey. In 1988, a nationally representative sample of 1,880 never-married, non-institutionalized males ages 15 to 19 living in the contiguous United States was surveyed. The original sample of 1,880 males was drawn as a multistage area probability sample that oversampled for Blacks and Hispanics. The study's primary objective was to determine adolescent males' behaviors, education and knowledge concerning human sexuality, contraception, and sexually transmitted diseases. Wave 1 data were collected between April and December 1988. The primary mode of data collection was face-to-face interviews. The most sensitive topics (e.g., substance use, risky sexual behaviors) were assessed with confidential, written self-administered questionnaires. Extensive personal histories of sexual activity and contraception use were gathered, as well as respondents' personal perceptions of the various costs and benefits of contraceptive use and fathering children. Information on school attendance and recent employment history were also included. Wave 2 of NSAM, which is also referred to as the Follow-up Survey of Young Men (FSAM), was conducted between November 1990 and March 1991, when respondents were generally between the ages of 17 and 22. Of those respondents that participated in Wave 1, the follow-up rate was 89 percent (N=1,676). Data collection procedures were similar to that of Wave 1, with the use of face-to-face interviews and self-administered questionnaires.

National Survey of Child and Adolescent Well-Being (NSCAW)

Investigators: Research Triangle Institute

The Administration on Children, Youth, and Families and the Office of the Assistant Secretary for Planning and Evaluation have undertaken the National Survey of Child and Adolescent Well-Being (NSCAW). NSCAW makes available, for the first time, nationally representative longitudinal data drawn from first-hand reports of children and families or other caregivers who have had contact with the child welfare system. Data from service providers are also collected. NSCAW is the first national study to provide detailed information on the experiences of children and families with the child welfare system and to collect measures of well-being for this population. The NSCAW is designed to address the following questions: What paths do children follow into and through the child welfare system? What factors affect investigation, services, placements, and length of involvement? What are the long- and short-term outcomes for children and families in the child welfare system in terms of safety, well-being, and permanence? The target population for the NSCAW includes all children and families that enter the child welfare system. Two samples were drawn from the population in 92 participating county child welfare agencies throughout the nation. The CPS sample includes 5,501 children, who were between the ages of 0 and 14 years at the close of the investigation. All investigations for the sample were closed between October 1, 1999 and December 31, 2000. The second sample consists of an additional 727 children, who were in out-of-home care for about 12 months at the time of sampling. This second group, referred to as the One Year in Foster Care (OYFC) Sample, was selected to allow special analysis related to the experience of out-of-home care. Waves 2, 3, and 4 take place 12, 18, and 36 months after the close of the investigation. The NSCAW II study design essentially mirrors that of NSCAW I. The NSCAW II cohort includes 5,872 children, aged birth to 17.5 years old, who had contact with the child welfare system within a 15-month period that began in February 2008. Children were sampled from investigations closed during the reference period. The cohort of 5,872 children was selected from 81 of the original NSCAW 92 Primary Sampling Units (PSUs) in 83 counties in 30 states that agreed to participate in NSCAW II. Retaining most of the NSCAW I PSUs will allow researchers to assess the change in context from the late 1990s, and enable longitudinal analysis of organizational measures such as staff turnover, climate, and work environment. Like NSCAW I, NSCAW II is a longitudinal study with multiple informants associated with each sampled child, to get the fullest possible depiction of that child. Face-to-face interviews or assessments were conducted with children, parents, and nonparent adult caregivers (e.g., foster parents, kin caregivers, group home caregivers), and investigative caseworkers. Baseline data collection began in March 2008 and was completed in September 2009. The second wave of the study, 18 months after the close of the NSCAW II index investigation, began in October 2009 and was completed in January 2011. At Wave 3, children and families were reinterviewed approximately 36 months after the close of the NSCAW II index investigation. The NSCAW II cohort of children who were approximately 2 months to 17.5 years old at baseline ranged in age from 34 months to 20 years old at Wave 3. Data collection for the third wave of the study began in June 2011 and was completed in December 2012.

National Survey of Children, 1976

Investigators: Child Trends, Inc.

The main purposes of this 1976 survey were to: assess physical, social, and psychological well-being of different groups of American children, and develop a national profile of the way children live and the care they receive. The sample was a multi-stage stratified probability sample of households in the continental U.S. containing at least one child in the age range of 7 through 11 years at that time (born between 1964 and 1969). Black households were oversampled. Data were gathered on 2,301 children, which represented 1,747 households. Interviews were conducted with the eligible child and the parent most capable of providing information about the child, usually the mother. A follow-up study of schools attended by the children was also carried out. In 1981, a reinterview survey was conducted with all of those children who were in a high conflict or disrupted family in 1976, and with a subsample of the others. Most of the background and outcome measures were repeated in the 1981 survey. In addition, new data were gathered on patterns of parent-child interaction and on outcome areas more relevant for teenage children, including dating and sexual activity, drinking, smoking, drug use, and delinquency. The data from the 1981 reinterview are also available from this collection. Note for users of DAAPPP Data Sets #01-B1DAAPPP data sets 01 through B1 are comprised of a User's Guide, SPSS syntax files (*.SPS or *.SPX) and raw data files only. Most of these datasets contain SPSS syntax files that use Job Control Language (JCL) from 1980s versions of SPSS-X. Because the syntax is old, the syntax files require editing to conform to the current syntax standards used by SPSS/Windows or SPSS/Unix.
