This study adapted a psychological assessment tool called the Ego Dissolution Inventory for use in Brazil. Ego dissolution refers to the profound sense of losing one’s sense of self that people experience when using psychedelics like psilocybin mushrooms and LSD. The researchers found that the adapted Brazilian version works well and identifies three dimensions of the experience: confidence/assertiveness, ego dissolution, and ego inflation. This validated tool can now help researchers in Brazil better understand psychedelic experiences and their potential therapeutic benefits.
