In the datafile the variable names and labels are in english, however the questionnaire, and answers in string variables are in french (given the context that this study was held in). Documentation, apart from the original questionnaire, are provided in english (syntax files for the four waves, as well as a document with references for item origins) and allow to link between the questionnaire questions, variables in the dataset, and the constructs. Any additional information or assistance with the data can be obtained by contacting the LOLYS team.
The dataset contains two conference posters, including information concerning attrition and description of the sample, central variables, and some results.
