Persian Norms for The Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C)

The Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C), is the most commonly used measure of hypnotizability. In Persian (Farsi), there was a lack of a valid test for hypnotizability. The norms for different language versions of the SHSS:C are important for evaluating the cross-language validity of the measure and determining the ability to compare research findings using the SHSS:C samples of different languages. In this study, a Persian translation of SHSS:C was administered to 321 Farsi-speaking individuals from the cities Tehran and Mashhad. Then, different parameters of the measure, including the distribution, normality, internal consistency, difficulty, and comparison with other SHSS:C norms, have been evaluated and presented. The results indicated that the Persian SHSS:C has good reliability, which is in line with the other language versions of the scale, and the scores from the Persian SHSS:C are comparable to those of the other language versions.
