Abstract
Background: The States of Consciousness Questionnaire (SOCQ) was developed to assess the occurrence features of the change in consciousness induced by psilocybin, and includes the Mystical Experience Questionnaire (MEQ), developed to assess the ocurrence of mystical experiences in altered states of consciousness.
Objective: To translate the SOCQ to Brazilian Portuguese and validate the 30-item MEQ.
Methods: The SOCQ was translated to Brazilian Portuguese and backtranslated into English. The two English versions were compared and differences corrected, resulting in a Brazilian translation. Using an internet-survey, 1504 Portuguese-speaking subjects answered the translated version of the SOCQ. The 4-factor version of MEQ30 was analyzed using confirmatory factor analysis and reliability analysis.
Results: A Brazilian Portuguese version of the SOCQ was made available. Goodness-of-fit indexes indicated that data met the factorial structure proposed for the English MEQ30. Factors presented excellent to acceptable reliability according to Cronbach's alpha: mystical (0.95)positive mood (0.71)transcendence of time/space (0.83)and ineffability (0.81).
Discussion: The Brazilian Portuguese version of the MEQ30 is validated and it fits in the factorial structure performed on the original English version. The SOCQ is also available to the Brazilian Portuguese speaking population, allowing studies in different languages to be conducted and compared systematically.Inst Plantando Consciencia, Sao Paulo, SP, BrazilUniv Estadual Campinas Unicamp, Dept Psicol Med & Psiquiat, Campinas, SP, BrazilUniv Fed Sao Paulo Unifesp, Dept Psiquiat, Sao Paulo, SP, BrazilDepartamento de Psiquiatria, Universidade Federal de São Paulo (Unifesp), São Paulo, SP, BraziWeb of Scienc
