CARVALHO, Cláudia; MAZZONI, Giuliana; KIRSCH, Irving  and  LEAL, Isabel. Waterloo-Stanford Group C (WSGC) Scale of Hypnotic Susceptibility: Presenting a Portuguese version for a scale of hypnotic susceptibility. Psic., Saúde & Doenças [online]. 2006, vol.7, n.1, pp.3-11. ISSN 1645-0086.

Hypnosis is an unusual procedure in Portuguese research. Therefore reliable and valid scales in Portuguese language suitable to assess hypnotic behaviour are inexistent. In this article a Portuguese version of the Waterloo-Stanford Group C (WSGC) Scale of Hypnotic Susceptibility (Bowers, 1993, 1998) is presented. The original scale of a 20m standard induction procedure and 12 hypnotic suggestions was translated to Portuguese and back into English to ensure protocol fidelity. The sample consisted of 707 volunteer's college students of both sexes, age form 17 to 49 years old. The findings show similar distribution and high significant correlations to the references samples. Although Alpha de Cronbach reliability coefficient is lower than similar coefficient in the reference samples (.62) is still acceptable for this type of scale. The Portuguese version of the WSGC:C has psychometric properties and can be utilized by Portuguese language-based researchers interested in assessing hypnotic susceptibility in group samples.
