Belgian norms for the Waterloo-Stanford Group C (WSGC) Scale of Hypnotic Susceptibility.

Belgian norms of the Waterloo-Stanford Group C Scale of Hypnotic Susceptibility (WSGC) are presented. A French translation of the WSGC was administered to 150 Belgium college students between October and December 2009. Belgium has 2 main linguistic groups, Dutch and French speakers. The present translation was conceived for all French-speaking populations. Score distribution, item analysis, and reliability of the WSGC are presented and compared to the normative sample of the WSGC. The results were also compared with 2 North American norms (University of Connecticut and Seton Hall University) and a Portuguese (translated) norm. The findings show that normative data from the French (Belgium) sample are in line with the reference samples. The only significant difference was the lower proportion of participants scoring within the high range of hypnotic suggestibility on the WSGC.
