Next Generation of Upper-Limb Prostheses, 1994

Investigators: William H. Donovan, Diane J. Atkins, Denise C.Y. Heard

The Next Generation of Upper-Limb Prostheses, 1994, is based on a study entitled The Next Generation of Myoelectric Prostheses, 1994, which established the TIRR National Upper Limb Amputee Data Base (copyright 1994, TIRR). The project was conducted by The Institute for Rehabilitation and Research (TIRR) from September, 1992 through November, 1994. This epidemiological study established a national data base on adults and children with upper limb loss and evaluated user perceptions of upper-limb prosthetic devices regarding: 1) costs, maintenance, and sensory feedback, 2) activities which can and cannot be done with available prosthetic technology, and 3) areas identified as most important for improvement in prosthetic devices. The TIRR National Upper-Limb Amputee Data Base is perhaps the most extensive survey ever conducted of upper limb amputees in North America concerning their prosthetic requirements. The archived study consists of one aggregate data file for four surveys (a screener survey and three longer surveys specific to prosthetic type). The one page screener survey includes data from 2,477 adults with upper-limb prosthetic devices or parents of children with upper-limb prosthetic devices.

Oakland County, Michigan Contraceptive Self-Care Study, 1987-1989

Investigators: Deborah Oakley

The Oakland County Michigan Contraceptive Self-Care Study: 1987-1989 is a study of nursing intervention in contraceptive care conducted from February 1987 through April 1989 at the Oakland County Health Division (OCHD) in Michigan. This study analyzed the prevalence and determinants of the quality of contraceptive use after a first visit to a family planning clinic. The study was quasi-experimental, comparing groups given various nursing intervention techniques with a control group on a variety of reported behaviors. Patients were interviewed at each of three clinics, their needs evaluated by a study nurse and (in the experimental groups) various interventions planned and carried out. Six to twelve months later, the patients responded to a telephone interview. Data were obtained from 1,819 first-time patients at three Oakland County Michigan clinics. This data set includes 639 variables from 360 condom using patients.

Parental Involvement in Minors' Abortion Decisions, 1990-91

Investigators: Stanley K. Henshaw and Kathryn Kost

The 1990-91 Alan Guttmacher Institute Survey of Parental Involvement in Minors' Abortion Decisions was designed to study the abortion decision-making behavior of pregnant minors and to determine whom they consulted in abortion decisions. Selfadministered questionnaires were distributed in abortion facilities to collect data on young women aged 17 and younger who were having an abortion in states without parental notification requirements. Forty-six abortion facilities provided data for 1,519 patients who received an abortion during a twelve-week period between December 1990 and June 1991. The questionnaire assessed perceptions of parental attitudes toward respondents' sexual behavior; communication between respondents, parents, and others about the abortion decision; parental reaction to the abortion; the consequences of informing parents about the abortion; and demographic measures including race, religion, school enrollment, and household composition.

Pennsylvania Study of Family Planning Discontinuation: Visit File, 1983-85

Investigators: Roberta Herceg-Baron

The second in a series of family planning studies (see DAAPPP Set Nos. 73, 75, and 76), the units of observation of this study are the family planning clinic visits of individual women on a visit by visit basis. The visit file includes data on counseling procedures, contraception practices, medical assistance coverage, referral sources, and childbearing histories of patients. Conducted from October 1983 through June 1985, patient visit abstracts (PVAs) from Automated Health Records of Philadelphia formed the bases of the study. The clinics involved are from two provider networks: the Maternal Family Health (MFH) representing a collection of counties in northeastern and northcentral Pennsylvania, and the Family Planning Council (FPC), representing southeastern Pennsylvania. Young women were oversampled; the stratified samples were subsampled to produce a representative (self-weighting) sample of 5% overall. For MFH, 22,909 visits by 4,990 women were included; for the FPC, 45,423 visits by 13,362 women were obtained.

Pennsylvania Study of Family Survey File, 1983-85

Investigators: Roberta Herceg-Baron

The fourth in a series of related studies, this Data Set surveys women who had discontinued family planning clinic services. Observations include data on educational and work background of the women surveyed, birth control history, clinics used by the women, and the reasons for discontinuation. The target population was defined as family planning clients in the FPC or MFH systems with the following characteristics: initial clinic visit after 7/01/80; last recorded visit before 6/30/83; not sterile or menopausal at last visit; not using family planning services for pregnancy testing; contact permitted; and not a transient client. The planned sample size was 600, with 400 from the FPC, and 200 from the MFH. The sampling frame was the set of all patients who were noted on their clinic's drop list. Records were sampled systematically at clinic sites, and the sample design was consequently a stratified sampling scheme. The actual interviews were conducted by trained personnel over the phone.

Philadelphia Collaborative Perinatal Project: Economic, Social, and Psychological Consequences of Adolescent Childbearing, 1959-1965

Investigators: Jeanne Marecek

This study examined the consequences of adolescent childbearing for mothers and for their children. The study sample included 2,178 Philadelphia women, primarily black, who were age 25 or younger at the birth of their first child. Data were obtained through interviews and medical examinations, and cover the socioeconomic circumstances of the mother during pregnancy and seven years later, as well as the intellectual and behavioral status of the child at birth and at ages 8 months, 4 years, and 7 years.

Philadelphia Study of Kinship Support for Adolescents in Family Planning Programs, 1980-1981

Investigators: Roberta Herceg-Baron & Frank F. Furstenberg

The primary objective of this study was to test the impact of a program designed to promote greater communication between adolescents and their families. It was hypothesized that greater communication would improve contraceptive use. Three interviews were scheduled: one at the initial visit to the clinic, one at six months, and one at about 15 months after the initial visit. Information was collected on contraceptive use, pregnancy history, amount of communication with family members about sex and birth control, and experiences in the clinic programs. In addition, participants reported on their educational and occupational situation, life goals, relations with peers, and heterosexual experiences. Many of the questions were drawn from comparable surveys (DAAPPP Data Set Nos. 1, 2, 4, 5, 44, 45, and 63-66). The questions have thus been extensively tested, and the findings could be compared to earlier work. The adolescents in the study were evenly divided between whites and blacks. They were recruited from six federally funded family planning agencies over a 20- month period from January 1980 to September 1981. Initial contact with the adolescents was made in person; the first interview generally occurred in the clinic, and remaining interviews were carried out by phone. Of those adolescents who were approached, 93% agreed to cooperate, yielding a total sample of 502, including 61 (14%) controls (a family support, periodic support, and an additional control group). Attrition rates were low (88% concluded the second interview, 85% concluded the second follow-up).

Philadelphia Study of Premarital Sex Relations and Pregnancy Among Puerto Rican Youths, 1980-1985

Investigators: Manuel J. Gutierrez, Braulio Montalvo, Kay Armstrong, David Webb and Gary Pickens

The present study examines the health and social consequences of adolescent premarital sexual relations on a sample of Puerto Rican youths. Investigators used a longitudinal design, covering a five-year period to answer the following questions: Of what consequence are adolescent premarital sexual relations on personal, familial, peer, and sociocultural factors in the lives of Puerto Rican youths as they enter into early adulthood? How do the experiences and consequences of adolescent premarital sexual relations differ by gender for the youths in the study? What are the personal, familial, and cultural factors associated with premarital sexual relations among Puerto Rican adolescents? What is the role of peers and other institutional sectors in the initiation or postponement of premarital sexual relations? The data in waves 1 through 3 (1980-1982) were originally collected by investigators M. Gutierrez and B. Montalvo as a study entitled Dropping Out and Delinquency Among Puerto Rican Youths: A Longitudinal Study. Waves 1 through 3 include information from both the respondent and a parent (usually the mother). The study includes variables on educational status and delinquent behavior, as well as variables which tap into intra-familial processes, family interfaces with school and community, and peer influences. In addition, questionnaires obtained standard demographic data such as age, sex, marital status, socioeconomic status, parents' educational and work status, family language, and number of years in the United States. The average ages of youths interviewed in waves 1 through 3 were 16.5, 17.5, and 18.5 respectively. Data from wave 4, collected when the youths were an average age of 21, documents the sexual behavior histories of a subsample of the youths interviewed in waves 1 through 3. Wave 4 contains data only from the youths. In this final wave, investigators documented not only the occurrence of premarital sexual behavior, but also the nature of the experience and relationship with the sexual partner. Information was collected on the youth's health status and economic well-being, along with extensive contraceptive, pregnancy, and birth histories. A number of items pertaining to educational and employment histories, family relations, drug and alcohol use, trouble with the law, aspirations for future, and cultural identification were included in the questionnaire.

Philadelphia Study of Psych. Factors Associated with Adolescent Fertility Regulation-Females, 1979-1981

Investigators: Eugenie Walsh Flaherty and Jeanne Marecek

The purpose of this study was to obtain very extensive information from adolescent females on a number of factors that were posited as being related to adolescent fertility regulation, including: parental communication regarding contraception, sex, and pregnancy; exposure to teenage pregnancy; attitudes toward various contraceptives, and contraceptive use. Two samples of adolescents were studied: those who were pregnant at the time of the first interview, and those who were not pregnant and had never borne a child at the time of the first interview. Respondents in the second sample were interviewed twice, with roughly a year's interval between interviews. The pregnant sample was drawn from four obstetrics/gynecology clinics participating in the study; the non-pregnant adolescent sample was drawn from the registry of the Philadelphia Collaborative Perinatal Project. Data were collected by the Philadelphia Health Management Corporation.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.

Philadelphia Study of Psych. Factors Associated with Adolescent Fertility Regulation-Males, 1979-1981

Investigators: Eugenie Walsh Flaherty and Jeanne Marecek

The purpose of this study was to obtain very extensive information from adolescent males on a number of factors that were posited as being related to adolescent fertility regulation, including: parental communication regarding contraception, sex, and pregnancy; exposure to teenage pregnancy; and attitudes toward various contraceptives. Males' sexual and contraceptive experience comprised the major dependent variables of interest. The sample consisted of 77 black adolescent males aged 14 to 18 years who were enrolled in the Philadelphia Collaborative Perinatal Project.
