README FILE FOR "Ruth Engs - CANADA dataset" http://hdl.handle.net/2022/17283 Created by: Dr. Ruth Clifford Engs Dept. Applied Health Science SPH Building Rm 116 1025 E. 7th St. Indiana University, Bloomington, IN 47405-4801 engs@indiana.edu http://www.indiana.edu/~engs/ with support from: Stacy Konkiel Science Data Management Librarian Herman B Wells Library Indiana University, Bloomington, IN 47405 iuswdata@indiana.edu --------------------------------------- FILE LIST This folder contains: ./allcan.dat – all Canadian data combined ./xusacan.dat – most important data file for replication of the study, a combination of American and Canadian databases. ./midwest88.dat - combined data from the Midwest collected by both Engs and Hanson ./engal87.dat - "raw" Midwest data collected by Engs; corrupted file ./Canada_Program.pdf - a file explaing the variables. Includes program syntax, which could be used to create a new program file in more current versions of SPSS. ./README_ENGS_Canada.txt - the current file, explaining the dataset and its components. --------------------------------------- FILE INFORMATION I. Dataset history These data were collected both in Ontario, Canada and in the United States in 1987-88 from students in various colleges and universities. The Midwest sample from data collected from Engs (Health Education) and Hanson (Sociology) were compared to data from university students in Ontario. American researchers: R. Engs and David Hanson Canadian researchers: Louis Glicksman and Cynthia Smith Research is based on adcard columns, which used letters of the English alphabet that were recoded into numbers. Because these letters were recoded, researchers reusing this data would need to recode their data to match the recoding in these files. The American questionnaire information was coded then keypunched onto cards and then later transferred onto tape. George Turner UITS transferred the early data bases from the tape into digital format for the Unix computer in 2002. Canadians had someone code their data to mainframe computer from paper form. Data was stored and analyzed on mainframes, then it was stored on a Unix system named Chrome and maintained by Indiana University's UITS, then it was stored on Engs' office and personal computers, and it was finally transferred to CD-R and handed off to IUScholarWorks team. The IUScholarWorks team reviewed all of Engs' submitted files and accessioned those files that are most useful to future researchers. We resaved files with incorrect extensions to reflect the proper formats (.sps for program files, etc). We removed files that are duplicates and/or contain errors. Any deleted files appear in cleaned, reformatted form in the final dataset uploaded to IUScholarWorks repository. No unique files were removed from the final collection submitted to the repository. II. Related questionnaire(s) The Canadian data are answers to the "Ontario" version of the Student Alcohol Questionnaire (available at http://hdl.handle.net/2022/17206). The US data are responses to the Original Student Alcohol Questionnaire (available at http://hdl.handle.net/2022/17153). It contains questions concerning demographic variables, drinking behaviors, problems related to drinking and knowledge of alcohol items. Both the test-retest reliability and the Kuder-Richardson reliability were .79 for the behavior and knowledge subscales. III. Specifics of data Data migrated from paper format in the following order: Paper surveys > Key punch card > Tape > Unix > CD-Rom. All data created in SPSS (software version circa 1987), tranferred to Unix via SPSS for Unix, Release 6.14. File extensions: .sps for program, .dat for source data Other data files used for selection of subsamples and for rewriting the SPSS programs include: - ALLCAN.DAT - MIDWEST88.DAT - ENGAL88.DAT Raw data were responses to questionnaires, submitted on paper, keypunched onto cards then transferred to tape, then migrated to Unix mainframe computer “Chrome”. No paper-based raw survey data survives. An output file would have been used to inform the publications below. However, this digital file was not found. Researchers reusing this data set will need to produce their own output file(s). Variable descriptions are found in the "Canada_Program.pdf" file. Archives may contain further descriptions that describes codings like “ROS” == religiosity. IV. Articles published from data (Database for the following articles is "XUSACAN.DAT".)

There are a number of possible issues with the files, as the tranferral of data from tape storage to UITS' storage to local storage introduced random errors into the files. Use these data with caution.
