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

Finnish norms of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) are presented. The aggregate sample of 285 subjects consisted of 3 groups (n = 129, n = 116, and n = 40) that were tested during 1996 and 1997. Comparisons are made with the original normative American sample, an Australian sample, and 3 translated adaptations of HGSHS:A in Danish, German, and Spanish. In the Finnish sample, Items 2 (eye closure), 11 (posthypnotic suggestion), and 12 (amnesia) received high passing percentage in comparison with the reference data, but generally the Finnish normative data were congruent with these index studies.
