A French version of the 30-item Revised Mystical Experience Questionnaire (MEQ30) was validated using data from 320 French individuals about their most significant psychedelic experience. The original four-factor structure—mystical, positive mood, transcendence, and ineffability—fit the data best with good to excellent statistical indices. Total scores strongly correlated with subjective ratings of mystical and drug intensity-related qualities but not with non-mystical qualities. The French MEQ30 score predicted positive changes in psychological well-being, relations with self and others, connection with nature, and creativity, while drug intensity and non-mystical qualities did not or only weakly predicted such changes.
