| Key points | The Hungarian version of the Sense of Agency Rating Scale (SOARS-HU) showed reliability and validity in confirmatory factor analysis and correlations with hypnotizability. Changes on its Involuntariness and Effortlessness subscales were associated with alterations in subjective conscious experience measured by the Phenomenology of Consciousness Inventory, and these associations remained significant after controlling for HGSHS:A scores, indicating that sense-of-agency changes during hypnosis are linked to alterations of consciousness independent of hypnotizability. |
Abstract
Changes in the sense of agency are defining feature of hypnosis. The Sense of Agency Rating Scale (SOARS) is a 10-item questionnaire, administered after a hypnosis session to assess alteration in the sense of agency. In the present study, a Hungarian version of the measure (SOARS-HU) is presented. The SOARS-HU and the Phenomenology of Consciousness Inventory (PCI) were administered to 197 subjects following hypnotizability screening with the Harvard Group Scale of Hypnotic Susceptibility Scale, Form A (HGSHS:A). Confirmatory factor analysis and correlations with hypnotizability demonstrate the reliability and validity of the SOARS-HU. Changes in the Involuntariness and Effortlessness subscales of the SOARS-HU were associated with alterations in subjective conscious experience, as measured by the PCI. These changes in subjective experience remained significant after controlling for HGSHS:A scores. These results indicate that changes in the sense of agency during hypnosis are associated with alterations of consciousness that are independent of hypnotizability.
