The Altered States Database: Psychometric Data of Altered States of Consciousness

Frontiers in Psychology July 2, 2018 Timo Torsten Schmidt, Hendrik Berkemeyer 75 citations

A new database, the Altered States Database (ASDB), compiles questionnaire data from research articles on experimentally induced altered states of consciousness (ASC). It includes data from MEDLINE-listed journals where ASCs were induced by pharmacological (e.g., psychoactive drugs) or non-pharmacological methods (e.g., breathing techniques, sensory deprivation) and assessed with standardized questionnaires. The database enables direct comparisons of psychological effects across different induction methods and supports meta-analyses to establish dose-response relationships specific to each method.
