Silence is golden: Documenting the speech production of participants and support providers in psilocybin administration sessions for the treatment of post-traumatic stress disorder

In a 12-week clinical trial of 25 mg COMP360 psilocybin for 22 participants with post-traumatic stress disorder, audio recordings showed that during drug-administration sessions speech by either party was rare: silence filled 78% of the time on average, compared to 25% to 30% in non-administration sessions. Thematic analysis of post-dosing interviews revealed that support was minimally enacted but experientially salient, autonomy was promoted through the introspective state and non-directive support, and primary modes of support during altered states included reassurance and validation. The minimal verbal interaction distinguishes this monitoring and support from conventional psychotherapies and MDMA-assisted therapy.
