Abstract
Hypnosis is an ancient mind-body intervention that has regained interest with the surge of research in the last decade documenting its clinical validity. Yet, theoretical controversies and misconceptions prevail among theorists, clinicians, and the general public, impeding the understanding, acceptance, replication, and use of hypnosis. Providing adequate information, which dispels misconceptions and promotes more balanced views, is warranted to facilitate the implementation and adoption of hypnosis in clinical and research settings. This review re-examines the conceptualisation of hypnosis throughout history and the theoretical controversies surrounding it while highlighting their meeting points and clinical implications. Despite dichotomies, a broad agreement appears across theoretical approaches regarding hypnotic analgesia effects, key components, and vocabulary. Further, theories highlight key factors of hypnotic responding. For instance, social theories highlight social and contextual variables, whereas state theories highlight biopsychosocial mechanisms and individual factors. Based on theories, the terms hypnotherapy or clinical hypnosis are recommended to refer to the therapeutic use of hypnosis in psychotherapeutic and medical contexts, respectively. This review concludes with a model that integrates various theories and evidence and presents hypnosis as a complex multifaceted intervention encompassing multiple procedures, phenomena, and influencing factors. This review intends to deepen our understanding of hypnosis, and promote its more rapid adoption and adequate implementation in research and clinical contexts, in addition to steering research towards evidence-based hypnotic practice. The review can have important research and clinical implications by contributing to advancing knowledge regarding hypnotic procedures, phenomena, and influencing factors.

A Randomized Controlled Trial of Clinical Hypnosis as an Opioid-Sparing Adjunct Treatment for Pain Relief in Adults Undergoing Major Oncologic Surgery. J Pain Res 2024; 17:45-59. [PMID: 38196969 PMCID: PMC10775151 DOI: 10.2147/jpr.s424639] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 11/27/2023] [Indexed: 01/11/2024] Open
Abstract
Clinical hypnosis is an effective strategy for managing acute pain in the surgical setting. However, the opioid sparing effects of clinical hypnosis are not as well understood. This pre-registered (NCT03730350) randomized, controlled trial (RCT) examined the impact of clinical hypnosis, pre- and post-surgery, on opioid consumption during hospitalization as well as on measures of pain intensity, pain interference, depressed mood, anxiety, sleep, and pain catastrophizing. Participants (M = 57.6 years; SD = 10.9) awaiting oncologic surgery were randomized to treatment-as-usual (n = 47) or hypnosis (n = 45). Intent-to-treat analyses were conducted using linear mixed effects modeling. A significant Group × Time interaction, F(6, 323.34) = 3.32, p = 0.003, indicated an opioid sparing effect of clinical hypnosis during the acute postoperative period. Hypnosis also protected against increases in pain catastrophizing at one-week after surgery, F (1, 75.26) = 4.04, p = 0.048. A perioperative clinical hypnosis intervention had a sparing effect on opioid consumption in-hospital after major oncologic surgery. These findings extend the efficacy of clinical hypnosis as an adjunct tool for perioperative pain management.

Geagea D, Ogez D, Kimble R, Tyack Z. Demystifying hypnosis: Unravelling facts, exploring the historical roots of myths, and discerning what is hypnosis. Complement Ther Clin Pract 2023; 52:101776. [PMID: 37402329 DOI: 10.1016/j.ctcp.2023.101776] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 06/04/2023] [Accepted: 06/14/2023] [Indexed: 07/06/2023]
Abstract
BACKGROUND AND PURPOSE Hypnosis, a mind-body treatment dating back to early human history, has regained attention in the last decade, with research suggesting its effectiveness for varied physiological and psychological ailments such as distress, pain, and psychosomatic disorders. However, myths and misconceptions have prevailed among the general public and clinicians, hindering the adoption and acceptance of hypnosis. It is important to distinguish myths from facts and discern what is hypnosis and what is not to enhance the understanding, acceptance, and adoption of hypnotic interventions. METHODS This narrative review traces the history of myths surrounding hypnosis in contrast to the evolution of hypnosis as a treatment modality. In addition to comparing hypnosis to other interventions with similar procedures and features, the review unravels misconceptions that have impeded the adoption and acceptance of hypnosis in clinical and research settings and presents evidence to demystify this intervention. RESULTS This review examines the roots of myths while presenting historical facts and evidence that support hypnosis as a treatment modality and alleviate misconceptions depicting it as mystical. Further, the review distinguishes hypnotic and non-hypnotic interventions with overlapping procedures and phenomenological features to enhance our understanding of hypnotic techniques and phenomena. CONCLUSION This review enhances the understanding of hypnosis in historical, clinical, and research contexts by disproving related myths and misconceptions to promote the adoption of hypnosis in clinical and research contexts. Further, this review highlights knowledge gaps requiring further investigations to steer research toward an evidence-based practice of hypnosis and optimise multimodal therapies embedding hypnosis.
