A validation study of a short-form hypnotic-experience questionnaire and its relationship to hypnotizability.
This study investigated the validity of a 16-item scale inquiring about hypnotic experience, drawn from the Hypnotic Experience Questionnaire developed by Kelly (1985) to measure components of hypnotic experience. We administered the HEQ-S and the Harvard Group Scale of Hypnotic Susceptibility: Form A (HGSHS:A) to 198 students. Factor analysis of the scale produced three stable principal components accounting for 70% of the data variance: Dissociation/Altered State (DAS), Rapport (RAP), and Relaxation (REL). Subscales representing these three factors and a composite measure, "General Depth," were constructed. Subscale correlations with HGSHS:A scores were highest for the DAS subscale (.69) and lowest for REL (.41). Applications of the HEQ-S in clinical and research use are considered.
