Summary
AI-generated from the abstractA new questionnaire, the Ego-Dissolution Inventory (EDI), reliably measures the experience of ego-dissolution—a temporary loss of the sense of self—during psychedelic drug use. The EDI shows strong psychometric properties, including internal consistency and construct validity, and its scores closely relate to the subjective psychedelic experience. This tool enables researchers to investigate the brain mechanisms underlying ego-dissolution, which may inform psychedelic-assisted psychotherapy and improve understanding of psychosis.

Abstract
Our results demonstrate the psychometric structure, internal consistency and construct validity of the EDI. Moreover, we demonstrate the close relationship between ego-dissolution and the psychedelic experience. The EDI will facilitate the study of the neuronal correlates of ego-dissolution, which is relevant for psychedelic-assisted psychotherapy and our understanding of psychosis.
