Italian norms for the Stanford Hypnotic Susceptibility Scale, Form C

This paper presents norms for an Italian translation of the Stanford Hypnot ic Susceptibility Scale, Form C (SHSS:C; Weitzenhoffer & Hilgard, 1962). Ar chival data on hypnosis research subjects recruited over a 10-year period o f research on hypnosis were pooled, resulting in an aggregate sample of 356 participants (263 female and 93 male). Score distribution, item difficulty levels, and reliability of the SHSS:C were computed. Of this group, 218 su bjects were administered the Harvard Group Scale of Hypnotic Susceptibility approximately 3 weeks prior to administration of the SHSS:C. The remaining 138 subjects received only the SHSS:C. Results suggest that the Italian ve rsion of the SHSS:C is a reliable and valid measure.
