Abstract:
The Polish version of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A; Shor & Orne, 1962) was administered to 1174 participants (968 women and 206 men). Polish data were compared with other norming studies. Point-biserial item-scale correlations ranged from r = .12 (posthypnotic suggestion item) to r = .49. The Kuder-Richardson correlation of .70 was within the range of the reference samples. Test-retest reliability coefficients were obtained from one group of participants tested twice in the same session (r = .69, p < .05), and another group 8 weeks apart (r = .58, p < .05). Females scored significantly higher than males.
