Hypnosis and hypnotherapy raise ethical issues that overlap with general healthcare ethics (autonomy, beneficence, nonmaleficence, justice, fidelity, confidentiality) and also include issues specific to altered consciousness, suggestibility, informed consent, competence, dual relationships, use of recordings and staged hypnosis, and research ethics. Below I summarize major ethical principles, common dilemmas, recommended best practices, and relevant professional standards and guidance.
Foundational ethical principles applied to hypnosis
Respect for autonomy: Obtain informed consent that is specific to hypnosis (explain what hypnosis is and is not, potential benefits, risks, alternatives, likely duration, and right to stop at any time).1
Beneficence and nonmaleficence: Use hypnosis only when there is reasonable expectation of benefit and avoid causing harm (e.g., retraumatization, false memories, physical injury, worsening symptoms).2
Competence: Practitioners must have appropriate training and supervised clinical experience in hypnotic methods for the specific problem treated.3
Fidelity and veracity: Be honest about qualifications, outcomes, and limits of hypnosis. Do not promise cures or make exaggerated claims.4
Confidentiality and privacy: Standard confidentiality rules apply; consider additional safeguards when sessions are recorded (audio/video).5

Informed consent: what it must cover
Informed consent for hypnosis should include:
A plain-language definition of hypnosis and common experiences during trance (e.g., focused attention, increased suggestibility).6
The nature and purpose of hypnotic techniques proposed and expected outcomes.7
Reasonable alternatives (CBT, medication, other psychotherapies, medical evaluation).8
Risks and side effects (transient distress, anxiety, headaches, emergence of difficult memories, rare dissociative reactions).9
Limits on confidentiality (mandatory reporting, supervision, if recordings used).10
Right to withdraw consent and stop the session.11

Competence, scope of practice, and training
Minimum training: There is no single universal credential; acceptable practice requires documented training from reputable programs, supervised clinical experience, and continuing education.12
Scope: Use hypnosis within one’s professional scope (e.g., psychologists, physicians, licensed mental health clinicians). Hypnosis for medical problems should involve coordination with treating physicians.13
Avoid practicing outside competence (e.g., complex trauma, dissociative identity disorder) unless you have specialized training and appropriate safeguards.14

Suggestibility, influence, and the risk of undue influence
Hypnosis increases suggestibility; clinicians must not exploit that by making suggestions for actions outside the client's values or legal/ethical boundaries.15
Avoid persuasive language that pressures clients to accept diagnosis or recommended treatments. Present balanced information and alternatives.16
References: 15. Lynn, S. J., & Kirsch, I., “Suggestibility and ethics in clinical hypnosis,” in Hypnosis and Suggestion (various reviews).
16. APA Ethics Code (2017), Standards on undue influence and exploitation.
Memory, false memories, and recovered memories
Use caution when working with memory retrieval under hypnosis: hypnosis can increase confidence in recollections and can lead to confabulation and false memories. Do not use hypnosis as a tool to reliably retrieve objective memories for forensic purposes.17
If memory work is clinically indicated (e.g., trauma processing), use evidence-based trauma-focused methods and obtain specialized training; document limits of reliability.18
References: 17. National Academy of Sciences and reviews on memory and suggestion; American Psychological Association task force reports on recovered memories (1996) and later analyses.

Staged hypnosis, public demonstrations, and entertainment
Stage hypnosis raises special ethical issues: informed consent in a performance context is limited; performers may expose participants to embarrassment and lack of follow-up care. Clinicians should avoid mixing entertainment with clinical practice and should not perform staged hypnosis in ways that exploit or harm participants.19
If participating in public demonstrations, obtain explicit informed consent, avoid coercion, ensure safety, and clarify limits of confidentiality and follow-up.20
References: 19. ASCH and BSCAH policy statements discouraging clinicians from unprofessional public demonstrations.
20. Ethical analyses in journals of clinical hypnosis on entertainment vs. therapeutic contexts.
Documentation, recordings, and confidentiality
Document hypnotic sessions in the medical/psychotherapy record including consent, techniques used, responses, adverse reactions, and coordination with other providers.21
Recordings: Obtain separate explicit consent for audio/video; explain storage, access, who may view, retention period, and risks. Secure files according to applicable privacy laws (HIPAA in U.S., GDPR in EU).22
References: 21. APA record-keeping guidelines; clinical hypnosis texts.
22. HIPAA guidance on psychotherapy notes and recordings; GDPR data protection rules.
Special populations
Children and adolescents: Obtain parental/legal guardian consent plus assent from the child; explain procedures in age-appropriate language; consider developmental capacity for consent and special vulnerabilities.23
Impaired decision-making or involuntary patients: Extra protections and documentation required; involve surrogate decision-makers as appropriate.24
Cultural competence: Be sensitive to cultural beliefs about hypnosis and altered states; obtain culturally informed consent and adapt metaphors and language.25
References: 23. Pediatric guidelines in hypnosis literature; ASCH position on children.
24. APA and medical ethics guidelines on treating those with impaired capacity.
25. Cross-cultural research in hypnotherapy; clinical guidance.
Advertising, claims, and marketing
Avoid misleading or exaggerated claims about outcomes or guaranteed cures. Use evidence-based statements and, when stating success rates, provide context and citation.26
Disclose relevant credentials and scope of practice. If you are not a licensed mental health or health professional, clearly state limitations of your role.27

27. APA and medical board standards for advertising; ASCH recommendations.
Research ethics in hypnosis
Apply standard research ethics: institutional review board (IRB) approval, informed consent that explains hypnotic procedures, risks, right to withdraw, and debriefing.28
Special care for suggestibility: avoid procedures that intentionally implant false memories; include safeguards for psychological distress and follow-up resources.29

Managing adverse events and dual relationships
If a client experiences distress, dissociation, or other adverse reactions, have plans for immediate clinical management, safety planning, and referral to higher-level care.30
Avoid dual relationships (therapist-as-trainer, therapist-as-friend, sexual relationships). Hypnosis contexts—especially trainings—can blur boundaries; be explicit about roles and maintain professional distance.31
References: 30. Clinical hypnosis handbooks on managing negative reactions; crisis intervention standards.
31. APA Ethics Code sections on multiple relationships and boundaries.
Clinical documentation: suggested elements
When documenting hypnosis/hypnotherapy sessions include:
Informed consent details (date, content discussed, signature).
Indication(s) for hypnosis and treatment plan.
Techniques used (induction method, trance depth, suggestions, imagery).
Client response and any adverse events.
Coordination with other providers and referrals.
Any recordings and consent for them.32
References: 32. APA clinical record-keeping guidance; ASCH sample templates.
Oversight, supervision, and continuing competence
Supervision is essential for clinicians newly learning hypnosis. Participate in peer supervision, case review, and continuing education to maintain competence and stay current with evidence and ethics.33
References: 33. ASCH and ISH recommendations on supervision and continuing education.
Quick practical checklist for clinicians (brief)
Obtain specific informed consent for hypnosis.
Verify scope-of-practice and documented training.
Screen for contraindications (e.g., active psychosis, severe dissociation, suicidality without supports).34
Avoid memory-retrieval for forensic purposes.
Secure recordings and document thoroughly.
Provide follow-up and emergency procedures.
Disclose credentials and avoid misleading claims.
