The Hypnotic Induction Profile (HIP) is a standardized assessment of hypnotizability featuring a validated 0-10 scoring system, that does not factor in posthypnotic amnesia. Using confirmatory factor analyses (CFA), we compared the 10-point scoring system with a new 12-point system that includes the posthypnotic amnesia item in independent samples of individuals with fibromyalgia (n = 98) and healthy adults (n = 97). Additionally, we explored associations of the two scoring systems with measures of hypnotic phenomena. CFA results indicate that the 12-point scoring system is a good fit for the 1-factor model of hypnotizability. Posthypnotic amnesia loaded highly on the model in the fibromyalgia sample, and moderately on the model in healthy adults. Furthermore, the 12-point scoring system correlated significantly with measures of hypnotic phenomena. We conclude that the 12-point scoring system is psychometrically equivalent yet conceptually more comprehensive than the 10-point scoring system.

The most well-established finding gleaned from decades of experimental hypnosis research is that individuals display marked variability in responsiveness to hypnotic suggestions. Insofar as this variability impacts both treatment outcome in therapeutic applications of hypnosis as well as responsiveness to suggestions in experimental contexts, it is imperative that clinicians and researchers use robust measures of hypnotic suggestibility. The current paper critically evaluates contemporary measures of hypnotic suggestibility. After reviewing the most widely used measures, we identify multiple properties of these instruments that result in the loss of valuable information, including binary scoring and single-trial sampling, and hinder their utility, such as the inclusion of suboptimal suggestion content. The scales are not well-suited for contemporary research questions and have outlived their usefulness. We conclude by outlining ways in which the measurement of hypnotic suggestibility can be advanced.

Hypnotizability assessment can inform hypnotic interventions, and studies on brief hypnotic inductions suggest that it may also confer therapeutic benefits. However, hypnotizability is rarely assessed in clinical practice due to limitations of current measures. The Elkins Hypnotizability Scale (EHS) improved upon such limitations and has been shown to be a very reliable and valid hypnotizability measure. This is the first study to examine the feasibility of the EHS as a therapeutic measure. Fifty-five participants were administered the EHS and randomized to two weeks of self-hypnosis with or without a recording. Results indicated that relaxation increased immediately after EHS administration, and relaxation and psychological distress improved after two weeks of self-hypnosis with the EHS induction. These results suggest that the EHS may be considered as a therapeutic measure and an avenue to introduce self-hypnosis in clinical practice with or without audio recordings.

Standard hypnotizability scales require physical contact or direct observation by tester and participant. The authors addressed this limitation by developing and testing the remote Hypnotic Induction Profile (rHIP), a hypnotizability test derived from the Hypnotic Induction Profile that is completed by telephone. To assess the validity of the rHIP, 56 volunteers naïve to hypnotizability testing completed both the HIP and the rHIP, with order of testing randomized. Results indicate a strong correlation between HIP and rHIP scores, r _s =.71(0.53-0.84), p <.0001, and good concordance, difference =.03(-0.53, 0.59), p =.91, independent of testing order. The rHIP had few complications. Possible advantages of using the rHIP include improving patient expectancy prior to scheduling a hypnosis session, increasing access to hypnotizability testing for remote interventions, and obviating resource-intensive in-person hypnotizability screening for trials that exclude subjects with certain scores.

This review addresses multicomponent theories of hypnotizability by focusing on 3 important exemplars from the history of hypnosis research: E. R. Hilgard's (1965) Hypnotic susceptibility; R. E. Shor's (1962) Three dimensions of hypnotic depth; and T.X. Barber's (1999) A comprehensive three-dimensional theory of hypnosis. Taken together, they illustrate the variety of hypnotic phenomena examined in research - overt responses, subjective experiences, and underlying processes - and the ways in which evidence about each has implied the existence of multiple underlying components. Particularly highlighted are the different ways in which the theories conceptualize the joint contribution of multiple individual differences. Also covered is relevant later work by other researchers as well as important issues remaining to be resolved.

Atopic dermatitis (AD) is a multifactorial disease that may have a psychosomatic component. In this study, the authors aimed to measure the effect of hypnosis on AD in a clinical setting. Patients with AD who never had systemic treatment were offered hypnosis sessions. Twenty-seven patients with AD and a mean age of 34.5 years participated in a mean of six hypnosis sessions (range 2 to 16). AD severity can be assessed with the Eczema Area and Severity Index (EASI). EASI score was calculated during the first and last hypnosis sessions for 21 patients. Eczema improved or resolved in 26 of the 27 patients. Mean EASI score for the 21 patients evaluated was 12 at the first session and 2.8 at the last session. Hypnosis may be useful in AD and may overcome the need for systemic treatments for some patients.

Many survivors of acute respiratory failure suffer from mood disorders following discharge from the hospital. We investigated the feasibility of intensivists delivering psychological support based on positive suggestion (PSBPS) to 20 intubated patients to reduce their psychological distress. Thirteen patients completed follow-up surveys. Of those, 9 remembered the intensive care unit physician talking to them, and 7 described it as comforting. Five patients (38%) met criteria for anxiety, depression, and acute stress. In comparison to historical controls, intervention may be associated with lower estimated odds of anxiety. PSBPS can be performed with patients in parallel with medical treatment to potentially reduce psychological morbidity and to humanize critical care. A larger randomized study is warranted to assess the efficacy of PSBPS.

A novel, heuristic model based upon chaotic complex systems theory and quantum mechanics is proposed to overcome the dichotomy between mind and body. The mind-body interface represents a chaotic system, ruled by the probability principle, as shown in quantum mechanics. Neuronal activity shows many patterns of chaotic behavior, and applications of chaotic patterns seem to be relevant for research regarding the mind-body relationship and the process of trance. A quantum consciousness theory has been proposed, largely controversial, since quantum physics applies to subatomic world and not to macrostructures, such as the brain. Quantum cognition is an emerging field that applies the formalism of quantum theory to model cognitive phenomena such as information processing by the human brain; it overcomes limits and shortcomings of cartesian dualism as well as quantum general theory. As hypnosis is a state of consciousness, it applies to hypnotic cognitive functioning rather than hypnotic structure.

The aim of this study was to develop a standardized hypnotherapeutic group program for stress reduction, test its feasibility, and measure its preliminary pre- to postintervention effects. In this prospective, single-arm feasibility study, healthy adult participants with self-assessed increased stress levels received 5 weekly group hypnosis sessions plus audio recordings. Twelve persons (10 females, mean (SD) age 48.9 (11.8) years participated. The mean (SD) intensity of perceived stress on a 0-to-100 mm VAS was reduced from 75.5 (11.5) mm at baseline to 33.9 (18.8) mm after 5 weeks. Cohen's perceived stress scale was reduced from 20.8 (5.7) to 13.8 (5.4). Focus group interviews showed that the study intervention was feasible and well accepted. Confirmatory testing of the intervention in a randomized controlled trial is necessary.

The purpose of this pilot study was to characterize test anxiety among first-year medical students at the University of Erlangen-Nürnberg and to test clinical hypnosis as a possible intervention. The "Prüfungsangstfragebogen," a shortened and revised German version of the Test Anxiety Inventory, was used to estimate test anxiety. It was administered 3 times: at the commencement of winter term 2017/18 and 2 days prior to each of 2 mandatory oral anatomy exams. The test-anxiety categories emotionality, worry, interference, and lack of confidence were evaluated. The effect of clinical hypnosis on test anxiety was estimated. The global test anxiety and lack of confidence scores were reduced significantly over time in the group that underwent clinical hypnosis but not in the control group. Direct comparisons of hypnosis vs. control group yielded no statistically significant differences in the test anxiety scores.
