Using rites of passage terminology, \u201cseparation\u201d corresponds to preparation, \u201climinal\u201d corresponds to the psilocybin dosing session, and \u201creincorporation\u201d corresponds to integration. In our usage, the term \u201critual\u201d refers to intentionally structured, symbolic acts that embody and reinforce shared meaning, guiding participants through experiences that may otherwise feel unbounded or overwhelming. In the group psilocybin retreat model, ritual functions both psychologically\u2014by supporting emotional regulation, orientation, and meaning-making\u2014and communally\u2014by embedding the individual\u2019s process within a shared field of intention and care.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>To our knowledge this is the first FDA-approved clinical trial of a secular ritual-based group facilitation model for psychedelic therapy that is associated with empirically demonstrated safety and efficacy outcomes.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/28314425251404460","type":"journal-article","created":{"date-parts":[[2025,12,23]],"date-time":"2025-12-23T16:48:40Z","timestamp":1766508520000},"page":"222-230","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Group Retreat Psilocybin Therapy for People with Metastatic Cancer with Anxiety and Depression: A Rite of Passage Facilitation Model for a Phase 1\/2 Study"],"prefix":"10.1177","volume":"4","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7903-0477","authenticated-orcid":false,"given":"Anthony L.","family":"Back","sequence":"first","affiliation":[{"name":"Department of Medicine, University of Washington, Seattle, Washington, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bonnie A.","family":"McGregor","sequence":"additional","affiliation":[{"name":"Orion Center for Integrative Medicine, Seattle, Washington, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lindsay","family":"Billingsley","sequence":"additional","affiliation":[{"name":"Private Practice, Squamish, British Columbia, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dianna","family":"Blom","sequence":"additional","affiliation":[{"name":"Harmony Retreats, Poulsbo, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"George","family":"Callan","sequence":"additional","affiliation":[{"name":"Private Practice, Squamish, British Columbia, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susanna","family":"Myers","sequence":"additional","affiliation":[{"name":"Fred Hutch Cancer Center, Seattle, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Guy","sequence":"additional","affiliation":[{"name":"Seattle Mindfulness Center, Seattle, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameet","family":"Kumar","sequence":"additional","affiliation":[{"name":"Memorial Healthcare System, Hollywood, FL, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melissa","family":"Layer","sequence":"additional","affiliation":[{"name":"Harmony Retreats, Poulsbo, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jackie","family":"Levin","sequence":"additional","affiliation":[{"name":"Harmony Retreats, Poulsbo, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliana","family":"Perez","sequence":"additional","affiliation":[{"name":"Fred Hutch Cancer Center, Seattle, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Thompson","sequence":"additional","affiliation":[{"name":"Private Practice, Squamish, British Columbia, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kathy","family":"Salmonson","sequence":"additional","affiliation":[{"name":"Harmony Retreats, Poulsbo, WA, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph","family":"Whinney","sequence":"additional","affiliation":[{"name":"Private Practice, Squamish, British Columbia, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leslie Lazar","family":"Thorn","sequence":"additional","affiliation":[{"name":"Department of Medicine, University of Washington, Seattle, Washington, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,12,9]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD015383.pub2"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpainsymman.2023.06.006"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.35010"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.35024"},{"key":"e_1_3_3_6_2","article-title":"Social identity processes as a vehicle for therapeutic success in psychedelic treatment","author":"Newson M","unstructured":"Newson M, , Haslam SA, , Haslam C, et al.
