An Observational Study on the Effects of Psilocybin Truffle Use in a Retreat Setting

DOI

Daily self-report data from fourteen adults attending legal psilocybin truffle retreats in the Netherlands, sampled once per day for two weeks before the retreat and three months afterwards. Items were co-constructed with each participant, so the item set differs from person to person. The deposit includes one file per participant, a codebook giving the exact wording, answer type, and analysis role of every item, and a participant table recording item counts, retreat days, and how missing data were handled. Collected for the study reported in the book chapter Psychedelic Experiences and the Realization of Meaning in Life: An Enactive Account, and not limited to the analyses reported there.

14 daily assessment data files, one per participant (sub01 to sub15, excluding sub03); item codebook giving the wording, answer type and analysis role of every column; participant table with item counts, retreat days and missing-data handling; guide to the deposited materials (README.pdf)
