Montreal norms for the harvard group scale of hypnotic susceptibility, Form A

Abstract

Norms are presented for the Harvard Croup Scale of Hypnotic Susceptibility, Form A (HGSHS:A) of Shor and E. Orne (1962). Comparisons are made on HGSHS:A between 3 Montréal samples (N = 220, N = 178, & N = 137) and the aggregate sample (N = 535). These are compared additionally with a normative group of Harvard students (Shor & E. Orne, 1963), a normative group of University of California at Berkeley students (Coe, 1964), a normative sample of Australian students (Sheehan & McConkey, 1979), and the original Stanford University normative sample which was tested individually on the Stanford Hypnotic Susceptibility Scale, Form A (Weitzenhoffer & Hilgard, 1959). Although the Montréal groups were heterogeneous in ethnic origin and first language, the present normative data are generally congruent with earlier studies.
