This repository contains the datasets for the six studies reported in “Prevalence and Validity of Nonordinary Experiences.” Data are organized by study, and each study includes a corresponding codebook. File naming conventions: Codebooks: Codebook_[study nickname]_dataframesDatasets: [study nickname]_Analysis_ValidationPaper Study structure: Study 1: Has its own dataset and codebook. Codebook: Codebook_Study1.xlsx Dataset: Study1_validationitems_df.xlsx Studies 2–4: Each study has its own dataset, but they all share a single codebook. Shared codebook: Codebook_Study2_3_4_dataframes.xlsx Dataset study 2: Study_2_Analysis_Validationpaper.csv Dataset study 3: Study_3_Analysis_Validationpaper.csv Dataset study 4: Study_4_Analysis_Validationpaper.csv Study 5: Uses data from Studies 1–4. These datasets are combined during the analysis (i.e., not pre-merged in the repository).Study 6: Uses data from Studies 2–4. These datasets are also combined during the analysis.
