Abstract This study examined the relationship between the Hypnotic Induction Profile (HIP) and several psychological tests: Tellegen Absorption Scale (TAS), Spontaneity Assessment Inventory-Revised (SAI-R), Dissociative Experiences Scale (DES), Short-Form Boundary Questionnaire (SFBQ), Mini Locus of Control (MLOC), Testoni Death Representation Scale (TDRS), and the Interpersonal Reactivity Index (IRI). Two hundred and forty volunteers were administered the above tests; 78 of them were also… 

Development and Validation of the Thought Impact Scale: A Measure of Subconscious Connectedness

The Thought Impact Scale is a reliable and valid measure that is likely to be useful in clinical hypnosis practice and hypnosis research and for quantifying communication between conscious and nonconscious mental functions.

Effects of Prehypnotic Instructions on Hypnotizability and Relationships Between Hypnotizability, Absorption, and Empathy

The clinical relevance of metasuggestions, intended to increase responsiveness to suggestions, is discussed as a strategy to improve treatment outcomes and strong correlations between the SHSS:C, HIP-H-IND, and HIP eye-roll scores indicate that both the HIP- H-IND and HIP-ER are robust measures of hypnotizability.

Well-Being in Highly Hypnotizable Persons

ABSTRACT Both hypnotizability and well-being are relevant to health. This study aimed to investigate whether high hypnotizability was positively associated with well-being and whether the latter was

Association of Thought Impact Scale Scores with Hypnosis Treatment Responses and Hypnotherapy-Seeking: A Confirmation Study

TIS scores were positively correlated with greater imagery vividness, sense of automaticity, and altered body perception during hypnosis, and their associations with several hypnotic phenomena were evaluated.


BIS/BAS activity partially accounted for the observed hypnotizability-related differences in the relation between cardiac interoception and pain experience, and pain threshold negatively correlated with heart rate.

Linear and non linear measures of pupil size as a function of hypnotizability

The present findings of pupil size cannot account for the differences in arousal and motor cortex excitability observed between highs and lows in resting conditions.

In medio stat virtus: The importance of studying mediums in hypnosis research

The recruitment of medium hypnotizables and the adoption of a within-instead of a between-subjects design currently seem to be some of the best recommendations for strengthening hypnosis research, as well as to renew the dialogue between clinical and experimental hypnosis.



Dispositional correlates of hypnosis: a phenomenological approach.

An attempt was made to construct and validate a questionnaire measure of hypnotic-like experiences based on Shor's (1979) 8-dimension phenomenological analysis of hypnosis, with results showing that each of the subscales possessed satisfactory levels of internal consistency and test-retest reliability.

Absorption and hypnotizability: context effects reexamined.

The results reaffirm the construct validity of absorption as both a major dimension of personality and as a predictor of hypnotic responsiveness.

The Relationship Between the Hypnotic Induction Profile and the Stanford Hypnotic Susceptibility Scale, Form C: Revisited

Hilgard’s comment raises some important issues, although many of these have little to do with the primary purpose of the study under discussion, and all agree on a new methodology which will be definitive in testing the validity of the ER hypothesis.

A Concurrent Validity Study between the Hypnotic Induction Profile (HIP) and the Stanford Hypnotic Clinical Scale for Adults (SHCS:A) in an Inpatient Sample: A Brief Report

It is indicated that while scores on the HIP and SHCS:A are significantly correlated the inter-correlations are not high enough to consider them as interchangeable measures.

Predicting Animal Attachment from Hypnotizability, Absorption, and Dissociation Scores

A positive correlation between scores on the Tellegen Absorption Scale and the Companion Animal Bonding Scale was found, but a positive link between animal attachment and score on the Dissociative Experiences Scale was failed.

Suggestibility, Expectancy, Trance State Effects, and Hypnotic Depth: II. Assessment via the PCI-HAP

The results suggested that the srHD scores were found to be a function of imagoic suggestibility, expectancy, and trance state and eye catalepsy effects; effects that appear to be additive and not (statistically) interactive.

Suggestibility, Expectancy, Trance State Effects, and Hypnotic Depth: I. Implications for Understanding Hypnotism

How the PCI-HAP may be used as a means to measure hypnotic responsivity from a more phenomenological state perspective, in contrast to more traditional behavioral trait assessment instruments like the Harvard, the Stanford C, or the HIP.

The relation between the Hypnotic Induction Profile and the Stanford Hypnotic Susceptibility Scales, forms A and C.

Positive but nonsignificant correlations were found between the Eye-Roll sign alone and SHSS in the 2 samples, and the Induction (IND) and Profile scoring methods of HIP were compared with SHSS.

Hypnotizability, the dissociative experiences scale, HGSHS: A amnesia, and automatic writing: is there an association?

Results found dissociation status and past performance on an ostensibly dissociative suggestion (i.e., amnesia) to be independent of passing the automatic writing suggestion.

Hypnotizability and Absorption in a Danish Sample: Testing the Influence of Context

The findings support the construct validity of the Danish translation of the TAS and reaffirm results of previous studies suggesting that absorption is an important predictor of hypnotizability.
