Exploratory, not a diagnosis
This newly developed questionnaire has not yet undergone formal psychometric validation. Domain scores describe reported experience; higher scores are not inherently better or worse. Missing responses are not scored as zero, and there is no overall psychedelic experience score.
Individual answers and scores will not be published. Research participation requires a separate, explicit consent decision.
