Australian norms and structural analysis for the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) are presented. Results relating to score distributions, item difficulty level, and reliability were considered for a large sample of Australian students (N = 4,752) obtained over eight years of testing at Macquarie University. The aggregated sample, which represents the largest normative study of the HGSHS:A undertaken to date, was compared to recent normative studies conducted in Australia, Canada, Germany, and Spain, using both English and non-English versions of the test. In general, the aggregated sample was consistent with other reference samples, and results indicated that the HGSHS:A continues to function well as an instrument for the initial screening of hypnotisability. Further, the emergence of a three-factor solution from the principal components analysis was also consistent with previous factor-analytic studies, and suggested that performance on this scale reflects three dimensions of hypnotic responding.
