This pilot study explored the feasibility of using ketamine to increase hypnotizability scores. Ketamine, classified as a dissociative hallucinogen, is used clinically as an anesthetic in high doses and as a treatment for chronic pain and depression in lower doses. Low-dose ketamine can contribute to dissociation and heightened perceptions and feelings of detachment, arguably hypnotic-like states. The authors predicted that a low dose of ketamine in healthy volunteers who scored in the low hypnotizable range on the Stanford Clinical Hypnotizability Scale would (a) cause an increase in subjective ratings of dissociation and (b) lead to an increase in hypnotizability...

This is a prospective randomized, controlled study of patients suffering from anxiety, depression, or mixed anxiety-depressive disorder attending a hypnotherapy clinic for 8 weeks. Participants were assessed with various clinical scales and randomly assigned to either the study or control group. The study group received 5 to 7 sessions of hypnotherapy through the 8-week period, whereas the control group received conventional psychiatric treatment. All patients' clinical conditions were reassessed at the end of the 8th week...

The study investigated whether the cardiac activity and cognitive-emotional traits sustained by the behavioral inhibition/activation system (BIS/BAS) may contribute to hypnotizability-related pain modulation. Nociceptive stimulation (cold-pressor test) was administered to healthy participants with high (highs) and low (lows) hypnotizability in the presence and absence of suggestions for analgesia. Results showed that heart rate increased abruptly at the beginning of nociceptive stimulation in all participants...

Expectancy has often been declared to be the single most important factor in the success or failure of any hypnotic intervention. Given this truism that expectancy is so crucial, this article shows how a potential patient's expectancy can be influenced and lowered or raised by the words and actions of the therapist. The essence of this innovative, simple, and quick method is that it is an expectancy-enhancement procedure that masquerades as a hypnotizability assessment. What makes this method powerful is the author's emphasis on the theatrical components of therapist performance (it even includes acting instructions)...

Shifts in hemispheric dominance were previously proposed to play a role in hypnosis. Participants (N = 32) were exposed to an active-alert hypnosis induction and a music-control condition while electrodermal activity was registered bilaterally, providing information on alterations in hemispheric dominance. The results suggest that highly hypnotizable participants show a shift to right-sided and low hypnotizable participants demonstrated a shift to left-sided electrodermal dominance in response to the induction, whereas no change in laterality is present in the control condition...

The concept of "flow" refers to a state of heightened attention and concentration in a current task. Benefits of entering a flow state may include the ability to optimize performance by reducing conscious cognitive processing. Various theories have suggested that flow is a state of consciousness similar to that of hypnosis. The present study addresses the relationship between flow and hypnotizability. In a college sample, a significant correlation was found between flow experience and hypnotizability, suggesting that those high in hypnotizability are more likely to experience flow states during hypnosis...

This pilot study evaluated the possibility that 2 interventions hypothesized to increase slower brain oscillations (e.g., theta) may enhance the efficacy of hypnosis treatment, given evidence that hypnotic responding is associated with slower brain oscillations. Thirty-two individuals with multiple sclerosis and chronic pain, fatigue, or both, were randomly assigned to 1 of 2 interventions thought to increase slow wave activity (mindfulness meditation or neurofeedback training) or no enhancing intervention, and then given 5 sessions of self-hypnosis training targeting their presenting symptoms...

Can posthypnotic suggestion (PHS) enhance cognitive abilities? The authors tested behaviorally and with event-related potentials (ERP) if sequential learning (SL), the ability to learn statistical regularities, can be enhanced with PHS. Thirty adults were assessed with the Stanford Hypnotic Susceptibility Scale (Form C) and an auditory SL task. Before this task, half the sample received a PHS to enhance SL, and the other half received the same suggestion under normal waking state. Response times and ERPs indicated a strong effect of PHS...

An RCT on the efficacy of hypnosis in improving adherence to antituberculosis treatment using the Health Belief Model (HBM). Sixty study subjects were sampled at random from tuberculosis patients who visited the Center for Pulmonary Community Health in Solo, Indonesia. Hypnotherapy with posthypnotic suggestions was delivered once a week over 6 months. The data on pretested 7 HBM constructs were analyzed using t test and path analysis. Hypnotherapy had a positive effect on perceived susceptibility, seriousness, threat, benefit, and self-efficacy...

Presurgical stress and its negative influences on postsurgical recovery and pain are well documented in the medical literature. Hence, the reduction of stress is advisable. The present study aimed to reduce stress using a hypnotic-based animated video. Thirty children aged 3 to 16 years hospitalized for ambulatory surgery for undescended testes or umbilical/inguinal hernia were recruited for the study. They watched the video 1 time prior to surgery in the presence of their parents and reported their anxiety and pain pre- and postvideo watching on a visual analogue scale...

This two-center quasiexperimental pilot study was to determine the effect of conversational hypnosis on patient comfort and parasympathetic tone, which may represent a quantitative measure of hypnotic depth, during regional anesthesia. The patients received conversational hypnosis in one center and oral premedication in the other. The patients' subjective comfort (0-10 rating scale) and objective parasympathetic tone, as assessed by the Analgesia/Nociception Index (ANI), were measured before and after regional anesthesia...

Safe-place inductions are considered important altered states of consciousness (ASC) to be (re)installed during trauma-informed psychotherapy. Coregulation aimed at changing implicit relational knowing and increasing integration and coherence through relational work and hypnotic techniques is crucial, as clients' abilities to self-soothe and regulate have become seriously impaired. Thus, resource-oriented metaphors as inner strength imagery is advocated. Also, methods such as creative-arts therapy and neurofeedback will induce ASCs, as most methods used with complex traumatized clients, due to their high hypnotizability...

On the basis of the transtheoretical model of change, we hypothesized that hypnosis would facilitate significantly greater movement through the stages of change toward smoking cessation in contrast to psychoeducation. Thirty participants were pretested for hypnotizability using the Elkins Hypnotizability Scale (EHS). Participants' readiness for change was assessed using the University of Rhode Island Change Assessment scale (URICA). The EHS relaxation induction was used to induce hypnosis. Hypnotic suggestions addressed motivation and ambivalence...

To determine whether hypnosis is more effective than conventional interviewing to find traumatic life events in patients with fibromyalgia, we carried out a within-subject experimental design with complete intragroup counterbalancing. Thirty-two women under care in a public primary care center gave 2 identical interviews, with an interval of 3 months, in which the occurrence of traumatic life events was explored, once in a state of wakefulness and once in a state of hypnosis. The state of consciousness was evaluated using 3 measures: bispectral index, skin conductance level, and pain intensity...

The possible cooperation between hypnotizability-related and placebo mechanisms in pain modulation has not been consistently assessed. Here, we investigate possible genetic bases for such cooperation. The OPRM1 gene, which encodes the μ1 opioid receptor-the primary site of action for endogenous and exogenous opioids-is polymorphic in the general population for the missense mutation Asn40Asp (A118G, rs1799971). The minor allele 118G results in decreased levels of OPRM1 mRNA and protein. As a consequence, G carriers are less responsive to opioids...

Research literature about hypnosis highlights the importance of clients' attitudes and beliefs toward hypnosis because they promote hypnotic responses and may predict the effectiveness of hypnotic interventions as well as minimize iatrogenic effects for clients. This study analyzes the factorial structure and psychometric properties with confirmatory methodology of the Valencia Scale of Attitudes and Beliefs Toward Hypnosis-Client Version, using a Portuguese sample. We expected to replicate the results obtained in previous research conducted with samples from various countries...

The aim of this study was to assess the efficacy of self-hypnosis in a therapeutic education program (TEP) for the management of chronic pain in 26 children aged 7 to 17 years. Outcomes of the study were a total or a partial (at least 1) achievement of the therapeutic goals (pain, quality of sleeping, schooling, and functional activity). Sixteen patients decreased their pain intensity, 10 reached all of their therapeutic goals, and 9 reached them partially. Self-hypnosis was the only component of the TEP associated with these improvements...

We investigated the association between hypnotizability, COMT polymorphism, P50 suppression ratio, and prepulse inhibition of acoustic startle response (ASR) in 21 high (HH) and 19 low (LH) hypnotizable subjects. The frequency of Met/Met carriers of COMT polymorphysm was higher in HH than in LH group (33.3% versus 10.6%, p = .049). Increased ASR amplitude and latency and decreased prepulse inhibition at 120 ms lead interval were found in the HH compared to the LH group. The effect of COMT genotype on prepulse inhibition was observed in LH group only...

High hypnotizability is associated with left-sided cerebral asymmetry, which could influence measurement of the Peripersonal Space (PPS). Right-handed participants with high (highs, n = 20), medium (mediums, n = 9), and low hypnotizability scores (lows, n = 20) performed the line bisection test on a computer screen automatically displaced at distances of 30, 60, and 90 cm from the subjects' eyes. Highs' results showed rightward bias of the bisection (Relative Error, RE) for all presentation distances...
