This study found that the Dissociative Experiences Scale (DES) significantly correlates with hypnotic susceptibility measures in undergraduates. These findings suggest a link between dissociation and hypnotizability, with potential clinical implications.
Area of Science:
- Psychology
- Psychiatry
Background:
- Hypnotizability is a trait that varies among individuals.
- The Dissociative Experiences Scale (DES) measures the frequency of dissociative experiences.
- Understanding the relationship between personality traits and hypnotizability is crucial for psychological research.
Purpose of the Study:
- To investigate the correlation between dissociative experiences and hypnotizability in an undergraduate population.
- To compare these correlations with previously published findings.
Main Methods:
- 311 undergraduates completed personality questionnaires, including the DES.
- Participants underwent the Harvard Group Scale of Hypnotic Susceptibility (HGSHS).
- Self-ratings of hypnotizability were also collected.
Main Results:
- A significant positive correlation was found between the DES overall score and the HGSHS summary score (r = .12, p < .05).
- The DES overall score also significantly correlated with self-rated hypnotizability (r = .13, p < .05).
- These correlation magnitudes were comparable to previous studies and the Tellegen Absorption Scale.
Conclusions:
- Dissociative experiences, as measured by the DES, are significantly associated with hypnotizability.
- The findings support the notion that personality factors influence hypnotic susceptibility.
- The results have potential implications for understanding and potentially treating conditions involving dissociation and hypnotizability.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
