Abstract

The Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) is widely used for group assessment of hypnotic responsiveness, yet normative data for Mandarin-speaking populations were lacking. This study administered the HGSHS:A to a large Taiwanese sample (N = 459) and compared performance profiles against 15 international normative datasets. The Taiwanese sample showed a mean total score comparable to Western norms, but specific item-level differences emerged: hallucination items showed lower pass rates, attributed to urbanization and cultural familiarity with the suggestion content, while group size moderated overall scores. Psychometric analyses confirmed acceptable internal consistency and item-total correlations. These norms provide validated benchmarks for hypnosis research and clinical assessment in Mandarin-speaking contexts.
