- Research in hypnosis frequently employs scales of hypnotizability to measure the hypnotic abilities of subjects prior to assigning them to research conditions. To economically achieve this objective scales have been adapted to group administration. This thesis describes such a scale--the Penn State Scale of Hypnotizability, and presents validity and reliability data. Comparisons are also made to another group scale--the Harvard Group Scale of Hypnotic Susceptibility.
Researchers have observed that subjects who are retested individually after an initial group screening with the Harvard Scale frequently score differently on a subsequent individually administered test of hypnotizability. The Penn State Scale was designed to include more difficult items than found on the Harvard Scale in order to provide a group scale better able to measure the characteristics of highly hypnotizable subjects. The results presented suggest that the Penn State Scale is at least as reliable as the Harvard Scale in predicting individually administered hypnotizability scale scores, and may be somewhat more reliable for subjects of high and low hypnotizability.
