I. Dataset history

From 1975 through 1994, Engs collected data from students in health classes using the Student Alcohol Questionnaire (SAQ). In later years, other scales were added such as the Codependency Scale (CODE) and the Student Health and Lifestyle Questionnaire (SHLS) to gain additional material to test hypotheses concerning alcohol, drugs and other variables. 

The demographic, alcohol knowledge and behaviors and other variables can be found in the questionnaires located in another section of IUScholarworks: https://scholarworks.iu.edu/dspace/handle/2022/17141

Data were migrated from paper format in the following order: Paper surveys > cards or direct input into Control Data Corporation (CDC) main frame computer > Unix mainframe > CD-Rom and PC. 

All data created in SPSS (software versions from 1983-1996), were transferred to Unix via SPSS for Unix.

Raw data were responses to questionnaires, submitted on paper. The questionnaire information was entered onto punch cards from 1975 through the early 1980s and then into the computer by work study students at Indiana University. Some examples of the raw analog data are in Engs’ papers in the Indiana University Archives, but the rest were destroyed. 

**Please note that due to change in technology that went from cards to magnetic tapes used with various mainframe computers, some data bases were lost or corrupted with extraneous special characters. Databases were reformatted to eliminate these characters by IUSW staff including Stacy Konkiel and Ethan Fridmanski. These data bases were retrieved in 2013 and 2021 from copies in a personal computer and may not accurately represent the data collected. Use data with caution in any calculations.....NOTE: corrupted files resulting from transfer from magnetic tape to unix format in 2002 are included in this dataset as a safety mechanism against inadvertent loss of crucial data points and for provenance.**

An output file was used to inform data for the publications.  


III. Publications and presentations from this data.

Numerous articles, book chapters, and presentations, were published or delivered from these databases over almost two decades. Representative samples can be found at https://scholarworks.iu.edu/dspace/handle/2022/16829
