Trait factors, state effects, and hypnotizability

Abstract

This study examined the relationship of 15 trait (e.g., absorption, ego-permissiveness) and 21 phenomenological variables (assessed by the Phenomenology of Consciousness Inventory) with performance on the Hamad Group Scale of Hypnotic Susceptibility, Form A. Factor analyses suggested three trait factors (absorption-permissiveness, general sensation seeking, and social desirability) and five state factors (dissociated control state, positive. affect, negative affect, attention to internal processes, and visual imagery). The factors correlated to hypnotizability were absorption-permissiveness, dissociated control, positive affect, and attention to internal pmesses. In predicting hypnotizability, the amount of variance accounted for by the trait factors was approximately 9%; an additional 22% was accounted for by state factors. The interactions did not account for any additional variance in predicting hypnotizability.
