National Survey of Men, 1991

Investigators: Koray Tanfer, John O.G. Billy, William R. Grady & Daniel H. Klepinger

The 1991 National Survey of Men was conducted to examine issues related to sexual behavior and condom use among U.S. men aged 20 to 39. Data collection and processing took place between March 1991 and January 1992. This survey was intended to serve as a baseline survey for a longitudinal study. Face-to-face interviews asked respondents about demographic information sexual initiation and current exposure; current wife or partner; previous marital relationships; other non-marital sexual partners; nonsexual romantic partners; health and risk-taking behavior; attitudes, perceptions, and knowledge of health-related and contraception-related issues. A set of self-administered questions assessed self-esteem, locus of control and attitudes toward marriage. This baseline study includes a total of 3,321 cases and 2,131 variables.

National Survey of Physicians' Attitudes Toward Abortion, 1975

Investigators: Leonard LoSciuto

The survey used a national probability sampling frame and includes 1,452 personal interviews with physicians and osteopaths stratified by four physician specialty types: obstetrician-gynecologists, psychiatrists, generalists, and physicians in other specialties. The probability of PSU selection was also taken into account. The questionnaire included queries on the justifications for abortion, opinions on effects of the 1973 Supreme Court abortion decision, practices regarding abortion in 1972 and currently, perceived influences on attitudes, and various details of background, training, and demographic variables. 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. If you require technical assistance in using or editing these syntax files, please contact Sociometrics' Data Support Group at 800.846.3475 or socio@socio.com.

National Survey of Unmarried Women, Aged 20-29, 1983

Investigators: Koray Tanfer

The survey's aim was the examination of these women's sexual, contraceptive, and fertility behaviors, and factors associated with these behaviors. Also collected from each respondent was information regarding residence, household composition, education, and employment. Complete pregnancy histories were obtained for all ever-pregnant women. A relationship history, spanning the time from the date of first sexual intercourse to the interview date, and which included characteristics of sexual unions and characteristics of partners, was obtained from all non-virgin respondents. In contrast to many previous fertility-related surveys, a key feature of this survey was the use of a life-history approach. The life-history calendar was used in conjunction with the interview schedule to facilitate the respondents' recall accuracy through visual linkages between certain experiences or events across domains. The intent of this method was to reconstruct a single lifehistory for each respondent which would reflect the timing and nature of each event occurring within the framework of the event domains selected for consideration. Data collected in this manner permit the examination of processes (or of events that are essentially processes), rather than structure, and provide the opportunity for assessment of the factors influencing these processes. In this context, the criterion event (dependent variable) as well as the predictor events (explanatory or independent variables) may be analyzed as processes. Examples of criterion events might include the formation of sexual unions, cohabitation, contraception, pregnancy, birth of a child, marriage, and so on. Such events are life course transitions, which often alter the postition of individuals in the life cycle, and are characterized by three interrelated dimensions: number, timing, and sequencing of events. More specifically, number refers to the proportion of individuals experiencing a certain event; timing refers to the pace at which the event occurs; and sequencing refers to the ordering of the event, with respect to some other event. Life-history data have a time dimension associated with them; the information collected on events within each domain includes both substantive content and a time value. The life-history approach, as used in this survey, is analogous to repeated measures on the same individuals at different time points. Therefore, it is somewhat different from an aggregation of data from several similar surveys that also contain a time dimension, but that present, in effect, successive measures on different samples of individuals. This approach, therefore, introduces some of the advantages of the longitudinal design into the cross-sectional survey. Life-history data differ also from panel data or "before-after" data which record data for the same individual at specific points in time only.

National Youth Risk Behavior Survey (YRBS) 2011

Investigators: Youth Risk Behavior Surveillance System, Centers for Disease Control and Prevention

The Youth Risk Behavior Surveillance System (YRBSS) is an epidemiologic surveillance system established by the Centers for Disease Control and Prevention (CDC) to monitor the prevalence of youth behaviors that most influence health. The 2005 Youth Risk Behavior Survey (YRBS) is one component of the YRBS. The 2011 National Youth Behavior Risk Survey (YRBS) is a school-based survey that provides data representative of 9th through 12th grade students in public and private schools in the United States. Since 1991, the YRBS has been conducted every two years by the Centers for Disease Control and Prevention (CDC). The national YRBS is one component of a larger surveillance system called the Youth Risk Behavior Surveillance System (YRBSS) that monitors six priority health-risk behaviors that contribute markedly to the leading causes of death, disability, and social problems among youth and adults in the United States. The 2011 National YRBS data set contains 207 variables administered to 15,425 respondents. Data were collected on the following priority risk behaviors among youth including: sexual behaviors that contribute to unintended pregnancy and sexually transmitted diseases, including HIV infection; behaviors that contribute to unintentional injuries and violence; alcohol and other drug use; tobacco use; unhealthy dietary behaviors; and inadequate physical activity. The YRBS also measures the prevalence of obesity and asthma among youth and young adults.

National Youth Risk Behavior Survey, 1993

Investigators:

The school-based 1993 National Youth Risk Behavior Survey (1993 National YRBS) was conducted by the Division of Adolescent and School Health, National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention (CDC). The National YRBS is one component of the Youth Risk Behavior Surveillance System (YRBSS), an epidemiological surveillance system that was established by (CDC) to monitor the prevalence of major risk behaviors among American youth. The 1993 National 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: behaviors that result in unintentional and intentional injuries; tobacco use; alcohol and other drug use; sexual behaviors that result in HIV infection, other sexually-transmitted diseases (STDs) and unintended pregnancies; dietary behaviors; and physical activity. This data set contains information on 91 variables from a nationwide sample of 16,296 students in grades 9-12, who were surveyed during February through May 1993. Results from the 1993 National 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 relevant national health objectives for the year 2000. Results also will be used to help focus programs and policies for comprehensive school health education on the behaviors that contribute most to the leading causes of mortality and morbidity.

Investigators: Centers for Disease Control and Prevention

The school-based 1995 National Youth Risk Behavior Survey (1995 National YRBS) was conducted by the Division of Adolescent and School Health, National Center for Chronic Disease Prevention and Health Promotion, Centers for Disease Control and Prevention (CDC). The National YRBS is one component of the Youth Risk Behavior Surveillance System (YRBSS), an epidemiological surveillance system that was established by CDC to monitor the prevalence of major risk behaviors among American youth. The 1995 National 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: behaviors that result in unintentional and intentional injuries, tobacco use, alcohol and other drug use, sexual behaviors that result in HIV infection, other sexually transmitted diseases (STDs), and unintended pregnancies, dietary behaviors, and physical activity. This data set contains information on 92 variables from the nationally representative sample of 10,904 students in grades 9-12 who were surveyed during 1995. Results from the National YRBS are 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 relevant national health objectives for the year 2000. Results also are used to help focus programs and policies for comprehensive school health education on the behaviors that contribute most to the leading causes of mortality and morbidity.
