Are Hypnosis and Dissociation Related? New Evidence for a Connection

The authors revisit the question of the existence of a relationship between hypnotizability and dissociative capacity. In the present study, the State Scale of Dissociation (SSD) replaced the commonly employed Dissociative Experiences Scale (DES) as a measure of dissociation, due to the latter capturing primarily pathological aspects of dissociation. Relationships between the Harvard Scale of Hypnotic Susceptibility, Form A (HGSHS:A), the SSD, and the Phenomenology of Consciousness Inventory (PCI) were assessed in the context of hypnosis. Robust results were found when comparing pre- to post-SSD scores, suggesting heightened nonpathological forms of dissociation are indeed related to hypnotizability. The appropriateness of the DES and similar trait-based measures for evaluating hypnotic phenomena is discussed as well as the relationships between PCI and SSD subscales.
