The Toledo Adolescent Relationships Study Available under Restricted Data Contract
DSDR is please to announce the availability of the first wave of The Toledo Adolescent Relationships Study (T.A.R.S) under restricted data contract. TARS is a longitudinal study funded by a grant from the National Institute of Child Health and Human Development, and conducted by the sociological research team of Peggy C. Giordano, Monica A. Longmore, and Wendy D. Manning. This study explores the relationship qualities and the subjective meanings that motivate adolescent behavior. More specifically, this study seeks to examine the nature and meaning of adolescent relationship experiences (e.g., family, peers, and dating partners) in an effort to discover how experiences associated with age, gender, and race and ethnicity influence the meaning of dating relationships. The study further investigates the relative impact of dating partners and peers on sexual behavior and contraceptive practices, as well as involvement in other problem behaviors that can contribute independently to sexual risk taking.
The longitudinal design of the TARS includes a schedule of follow-up interviews one, three, and five years after the initial interview. Four waves of data have been collected (2001, 2002, 2004, and 2006). The sampling frame was derived from public and private school enrollment records in Lucas County, Ohio. School attendance, however, was not a requirement for inclusion. A stratified, random sample (n=1,321) was then drawn from all 7th, 9th, and 11th grade youth residing in Lucas County in the fall of 2000. Data were collected from adolescent respondents through structured in-home interviews utilizing laptop computers. Parent data was collected via a short, self-administered questionnaire at the first wave. The TARS codebook and User Agreement are available for download under ICPSR Study #4679.

The Japan 2000 National Survey on Family and Economic Conditions (NSFEC) Data Available
DSDR is pleased to announce the availability of the Japan 2000 National Survey on Family and Economic Conditions (NSFEC): DSDR/ICSPR Study No. 21120.
NSFEC was collected by the Keio University COE project. It is a national, two-stage stratified probability sample of Japanese men and women aged 20-49. Three hundred fifty locales were randomly selected based on the 2000 census tract distribution. Then, 20 individuals aged 20-49 were randomly selected within each locale, based on the registration of current domicile (jumin kihon daicho). Because one of the major objectives of the survey was to collect information on early life course, individuals aged 20-39 were selected at twice the rate of those aged 40-49.
Information was collected from selected individuals through self-administered questionnaires that were distributed and subsequently picked up by field workers. A total of 4,482 usable questionnaires were returned, a response rate of 64 percent. The response rate was particularly low for those aged 20-24 (55 percent). For the remainder, the response rate was 71 percent. Weights were computed based on age, sex, the size of place of residence, and region.

The Children of Immigrants Longitudinal Study (CILS) Data Available
DSDR is pleased to announce the availability of The Children of Immigrants Longitudinal Study (CILS): DSDR/ICSPR Study No. 20520.
CILS is a longitudinal study designed to study the adaptation process of the immigrant second generation which is defined broadly as U.S.-born children with at least one foreign-born parent or children born abroad but brought at an early age to the United States. CILS continues to be the largest longitudinal project on the subject of second generation adaptation in the United States. The study was directed by Alejandro Portes of Princeton University and Ruben G. Rumbaut of University of California-Irvine, and was supported by research grants from the Russell Sage Foundation, the Andrew W. Mellon Foundation, the Spencer Foundation, and the National Science Foundation.
The DSDR CILS data includes three waves of surveys of a second-generation panel followed for a decade from 1992 to 2003, as well as parental survey data and academic history data collected from three Unified School Districts in South Florida and Southern California. The original survey was conducted with large samples of second-generation children attending the 8th and 9th grades in public and private schools in the metropolitan areas of Miami/Ft. Lauderdale in Florida and San Diego, California. The first survey, conducted in Spring 1992, had the purpose of ascertaining baseline information on immigrant families; children's and parents' demographic characteristics; language use; ethnic self-identities; self-esteem and depression; school engagement and academic aspirations and attainment. The total sample size was 5,262. Respondents came from 77 different nationalities, although the sample reflects the most sizable immigrant nationalities in each area.
Three years later, corresponding to the time in which respondents were about to graduate from high school, the first follow-up survey was conducted. Its purpose was to examine the evolution of key adaptation outcomes, including language knowledge and preferences; ethnic identity; self-esteem; and academic attainment over the adolescent years. The survey also sought to establish the proportion of second-generation youths who dropped out of school before graduation. This follow-up survey retrieved 4,288 respondents or 81.5 percent of the original sample. Together with this follow-up survey, a parental survey was conducted. This survey targeted half of the total universe of parents, selecting them on a random basis. Unlike the student surveys, which were conducted mostly via self-administered questionnaires in school, the parental interviews were conducted face-to-face and mostly at home.
During 2001-03, or a decade after the original survey, a final follow-up was conducted. The sample now averaged 24 years of age and, hence, patterns of adaptation in early adulthood could be readily assessed. The original and follow-up surveys were conducted mostly in schools attended by respondents, greatly facilitating access to them. Most respondents had already left school by the time of the second follow-up so they had to be contacted individually in their places of work or residence; they were located not only in the San Diego and Miami areas, but also in more than 30 different states, with some surveys returned from military bases overseas. Mailed questionnaires were the principal source of completed data in this third survey. In total, CILS-III retrieved complete or partial information on 3,613 respondents representing 68.9 percent of the original sample and 84.3 percent of the first follow-up. The longitudinal character of the data makes it possible to construct predictive models for sample attrition. Fieldwork for this last phase--from internet searches to the implementation of all possible methods of data collection--lasted over 24 months. Relevant adaptation outcomes measured in this survey include educational attainment, employment and occupational status, income, civil status and ethnicity of spouses/partners, political attitudes and participation, ethnic and racial identities, delinquency and incarceration, attitudes and levels of identification with American society, and plans for the future.

QualAnon
DSDR announces the availability of a new Web based tool to assist in the anonymization of qualitative data. In collaboration with Susan Watkins at the University of Pennsylvania and ICPSR CNS programmer Peggy Overcashier, we have developed a Web based program that streamlines the process of removing or changing identifiers in qualitative data.
The program, QualAnon, takes a user-generated name key to replace identified names with pseudonyms. It has several options, including the option to have an annotated document created that identifies where specific changes have been made in the document. The program also creates a summary report that specifies the number of times a specific name has been replaced. In addition, QualAnon has a "batch" option that allows the users to anonymize several documents at once by uploading multiple documents as a Zip file using one corresponding name key.
QualAnon is a tool to assist in the removal of identifiers in qualitative research. It is not intended to replace the researcher's role in reducing disclosure risk and minimizing breach of respondent confidentiality.
