A review of studies on psychedelic-assisted therapy found no evidence that the number of therapy hours affects depression outcomes. The authors caution that this conclusion is tentative because the studies included small numbers of participants, varied widely in methods, and poorly documented the therapy provided. They call for future research to use more rigorous methods and standardized reporting to better understand the role of therapy.
People who recall insecure early attachment with parents report more intense psychedelic experiences—mystical, challenging, emotional breakthrough, ego dissolution, and sensed presence—during their most memorable psychedelic session. However, current adult attachment styles (anxiety and avoidance) are unrelated to the intensity of those experiences. The subjective features of naturalistic psychedelic use do not typically weaken the connection between a perceived insecure attachment history and current attachment insecurity. The study surveyed 185 Jewish adults online who had used psychedelics.
Combining attachment theory with the REBUS model offers a framework for understanding how psychedelic experiences can reshape spiritual and religious beliefs. Attachment theory holds that early caregiving relationships create internal working models that act as mental templates for later interpersonal and divine relationships. Psychedelic therapy may work by loosening rigid, defensive mental patterns—such as insecure attachment to others or God—while corrective relational experiences with a therapist or others amplify this effect. Three research proposals are outlined: individual attachment security predicts how people experience and integrate psychedelic sessions; effective psychedelic therapy should increase attachment security as a measurable outcome; and attachment-related processes—like feeling connected to others or God and reducing attachment-related anxieties—are key mechanisms in psychedelic treatment's clinical benefits.
