Expectancy versus absorption in the prediction of hypnotic responding.
The Absorption Scale, a measure of imaginative involvement, was administered to 64 subjects in the context of a hypnosis experiment and to an additional 64 subjects in a context unrelated to hypnosis. Expectancies of responding to hypnotic suggestions were assessed both before trance induction and after trance induction but before administration of hypnotic test suggestions. Hypnotic depth was assessed on the Long Stanford Scale (LSS) before the administration of test suggestions, and on the Inventory of Hypnotic Depth (IHD) after the hypnosis session. Absorption was correlated with hypnotic responsivity and expectancy, but only when assesed in the hypnotic context. Completing the Absorption Scale in a hypnotic context appeared to affect hypnotic responsiveness by altering subjects' expectancies. Only postinduction expectancies were uniquely predictive of response to hypnotic test suggestions, and all variables except the LSS were predictive of IHD scores. Results of path analysis supported the hypothesis that trance inductions alter expectancies for responding to hypnotic suggestions and that these altered expectancies determine subsequent hypnotic behavior.
