Respect autonomy and individualized communication preferences

The manuals converge on treating autonomy as central to the therapeutic relationship. Across the extracts, the manuals recommend collaborative, non-coercive communication, with room for questions, informed choice, and explicit consent before medication administration. Several sources also emphasise adapting the interaction to the person’s preferences, whether through formal or informal address, choice of name, or flexible ways of participating in sessions and related tasks. They also agree that autonomy is not unlimited in every moment, and that safety can set boundaries. The sources describe clear limits on leaving the room, device use, recording, and stopping participation, while still preserving dignity and as much choice as possible. In this sense, the manuals recommend balancing participant control with containment when risk or session structure requires it. The main differences are in emphasis and level of detail. The MDMA manual focuses most strongly on language style, recommending invitational phrasing, reflective listening, and suggestions framed as options rather than commands. The ketamine and psilocybin sources place more emphasis on procedural consent, withdrawal rights, session constraints, and practical preferences such as paper, tablet, or telehealth, while the cancer study adds specific choices about recording pauses and caregiver or transportation instructions.
