What does the research from the hypnotic susceptibility scale say about hypnosis?

Abstract A short scale for the measurement of hypnotic responsiveness was constructed for use with patients for whom the standard scales might prove too long, too uninteresting, or too tiring. Five… Expand

Abstract

Background

The relationship between normal personality and hypnotic susceptibility is important for understanding mental processing and mental disorders, but it is less consistent in normal people or in patients with a psychiatric disorder. We have hypothesized that the correlation exists but varies in individuals with different levels of hypnotizability.

Participants and methods

We invited 72 individuals with high (HIGH group) and 47 individuals with low (LOW group) hypnotic susceptibilities to undertake tests of NEO-PI-R and the Stanford Hypnotic Susceptibility Scale, Form C (SHSSC).

Results

The HIGH group scored significantly higher than the LOW group did on openness to experience and its facet openness to feelings. In the LOW group, SHSSC total was positively predicted by openness to ideas; age regression was positively predicted by openness to experience and negatively predicted by extraversion; anosmia to ammonia was negatively predicted by agreeableness; and negative visual hallucination was positively predicted by openness to experience. In the HIGH group, hallucinated voice was positively predicted by openness to experience and negatively predicted by agreeableness, and posthypnotic amnesia was positively predicted by extraversion and negatively predicted by openness to experience.

Conclusion

The associations between normal personality traits and hypnotic susceptibility items were weak and different in the two groups, which imply that managing mental or somatoform disorders might be through adjusting hypnotizability and mobilizing personality functions.

Keywords: hypnotic susceptibility, NEO-PI-R, normal personality trait, the Stanford Hypnotic Susceptibility Scale, Form C

Introduction

Hypnotic susceptibility is an ability of responsiveness to suggestions for changes in subjective experience and for alterations in perception, sensation, emotion, thought, or behavior.– The ability shows hereditary inclination and remains stable during the lifetime of an individual.– As a significant index reflecting the degree of hypnotic suggestions and inducement, it is purported to correlate with personality traits. In patients with a personality disorder, for example, the hypnotic features such as taste hallucination and anosmia to ammonia were correlated with the borderline personality disorder functioning style, and posthypnotic amnesia was correlated positively with the schizoid and negatively with the narcissistic styles.

Some normal personality traits were linked with hypnotic susceptibility, but their relationships were not always stable in healthy people.– The discrepancy might be resulted from various measurements of normal personality and hypnotic susceptibility. For instance, with the application of Intelligence Structure Test 2000 R and the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHSA), gender factor was reported as a moderator in the relationship between hypnotic susceptibility and intelligence.

However, even with the same personality measurement, results are not consistent with each other. For example, using the Minnesota Multiphasic Personality Inventory, one study indicated that people with high hypnotic susceptibility scored higher in depression, masculinity–femininity, and schizophrenia scales than people with low hypnotic susceptibility did, but another study failed to replicate the results. Nevertheless, more recent studies kept showing new evidence that persistence, emotional contagion, and unselfish/self-sacrificing, were linked with hypnotic susceptibility.

In addition, using HGSHSA and the NEO Personality Inventory’s openness to experience, Glisky et al have found that hypnotizability was weakly correlated with openness to experience domain and with its facets openness to fantasy, openness to esthetics, and openness to feelings. Similarly, Nordenstrom et al, using Carleton University Responsiveness to Suggestion Scale and Waterloo-Stanford Group Scale of Hypnotic Susceptibility, Form C in two phases, reported weak correlations between openness to experience and hypnotic suggestibility. By contrast, Green, using the Revised NEO Personality Inventory (NEO-PI-R) and NEO Five Factor Inventory (NEO-FFI) Professional Manual.

What determines susceptibility to hypnosis?

Hypnotic susceptibility is an ability of responsiveness to suggestions for changes in subjective experience and for alterations in perception, sensation, emotion, thought, or behavior. The ability shows hereditary inclination and remains stable during the lifetime of an individual.

What does hypnotic susceptibility measure?

Hypnotic susceptibility measures how easily a person can be hypnotized.

Can susceptibility to hypnosis be measured?

Individual differences in hypnotizability are measured by performance-based tests such as the Stanford Hypnotic Susceptibility Scale and the Harvard Group Scale of Hypnotic Susceptibility.

What percentage has low susceptibility to hypnosis?

A person's susceptibility to hypnosis is usually gauged as 'high', 'medium', or 'low'. Approximately 80% of the population are medium, 10% are high and 10% are low. Being able to reliably measure hypnotic susceptibility has allowed researchers to study hypnosis and its correlates in the laboratory.
