This dataset contains the data of the survey waves from age 11 to 20 (K4-K8) of the target population. The following documents help to understand the content of the data (partially restricted access):
• Handbook K4-K8 in two versions: Short version (public access) containing general information such as descriptions of questionnaire themes, source, derived constructs, and key publications ("K4-8_Handbook_short") and a long version providing a detailed overview of each scale, and item wordings ("K4-8_Handbook_long”).
• Overview of standard variables (e.g., sex, SES, treatment allocation) that are part of every data package on SWISSUbase
• Codebooks (questionnaires with question/variable names) in English
• Original questionnaires in German
• Scale syntaxes (SPSS) for each data collection wave
• File info including all variable/value labels and dataset structure
• Description of the z-proso project, containing general information on the project, methods and data ("z-proso_ProjectOverview", public access)
• Tabular overview on all z-proso project phases, data collections, and questionnaires including information on scales/domains, and page numbers in the original German questionnaires ("z-proso_DataCollectionsInstruments_W1-9", public access)
• A publication list with selected z-proso methods publications (public access)
The datafile is available in the CSV, SAV (SPSS), and DTA (STATA) formats.
The data is available with prior agreement of project co-directors (Manuel Eisner, Denis Ribeaud, Lilly Shanahan) only. The project direction will grant access to the data based on a research proposal. The research proposal needs to be in the form of a project description with the following components: research questions and hypotheses, operationalisation, planned publications, linking with other project or other data (if planned). If you have questions or need more detailed information or additional documentation, do not hesitate to contact the project direction (z-proso@jacobscenter.uzh.ch). The research proposal is part of the application form.
If you, as a data user, are or were a z-proso participant yourself (focal participant, primary caregiver, or teacher), you are required to contact us before submitting a proposal.
If you require further data from earlier data collections, or from other informants (parent, teacher), or from add-on data collections that are not (yet) available on SWISSUbase, please provide a brief outline of your research questions along with a rationale for your specific data requirements.
