Hypnosis and hypnotizability scales: A reply

Abstract

The use of the hypnotizability scales in the experimental setting is briefly reviewed, as is the need to separate the effect of hypnosis from the influence of factors such as relaxation and placebo which accompany the use of hypnosis clinically. The clinical relevance of the scales, most of which were developed primarily for experimental work, is affirmed by several studies conducted in the clinical context, in which the scales were used. Levels of hypnotizability have correlated well with patterns of clinical behavior. Although the scales are useful in many instances in helping to plan treatment strategy, their value in investigative studies is emphasized.

Sacerdote's (1982) criticisms of the scales are considered. While it is true that the scales are blind to some of the qualitative aspects of the hypnotic experience, the great majority of clinically hypnotizable patients are able to respond to the items on the scales. Sacerdote's reluctance to learn about the value of the scales is evident in his preference for conjecture when he could readily have gathered irrefutable data through the administration of the scales, without the least risk to the treatment of his patients, once the course of treatment was underway or complete.
