Folders organization

• research code: this is the folder with all the code and data for reproducible steps of our research project.
• using PREVis: if you want to use PREVis scales in a study, this is where we put all the resources you need. The folder contains a detailed PDF companion guide with a FAQ section and example study protocols. It also contains a folder with example data and code for visual analysis and presentation of your study results.
