Swedish norms for the Harvard Group Scale of Hypnotic Susceptibility, Form A

This article examines the norms for a Swedish adaptation of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) (Shor & Orne, 1962). In total, 291 subjects (199 females and 92 males) participated in the study. Comparisons are made between the Swedish sample and reference samples, which include English versions of the HGSHS:A from the United States and Australia, as well as 5 translated versions from Italy, Finland, Denmark, Spain, and Germany. In the Swedish sample, females scored significantly higher than males. Generally, however, the normative data from the Swedish sample are congruent with the reference samples and therefore can be used as a tool for initial screening of hypnotic susceptibility in Sweden.
