Here you can download different versions of the SVO Slider measure as a PDF document or as a z-Tree module. There are two versions (A and B) of the slider measure. Each version has the exact same items but the items are presented in a different order within each section to mitigate potential order effects. In our studies we have looked for order effects but not found any, so its not that serious of a concern. We also have posted a version of the SVO Slider without instructions so that researchers can write their own instructions, tailored for their own research. Below are also versions of the SVO measure in different languages, the z-Tree module, and instructions of how to implement the Slider Measure in Qualtrics. Lastly there are analysis tools (Excel, SPSS, MATLAB) that can be downloaded and used for scoring new data.
