Psychedelic communitas: Intersubjective experience during psychedelic group sessions predicts enduring changes in psychological wellbeing and social connectedness

First quantitative study of psychosocial factors in guided psychedelic group settings. Adapted the Communitas Scale (Cronbach's alpha = 0.92) and surveyed 886 participants. Communitas during ceremony significantly correlated with increases in psychological wellbeing (r = 0.22) and social connectedness (r = 0.25). Path analyses showed that positive relationships between participants and facilitators, and perceived emotional support, facilitated the emergence of communitas.
