| Normative data for the Mexican adaptation of the Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C; Weitzenhoffer & Hilgard, 1962) are presented. Twenty seven raters administered the scale to 513 Mexican volunteers. Score distribution, item analysis, and reliability of the SHSS:C are presented and compared to other international norming studies. The findings show that the Mexican adaptation of the SHSS:C has psychometric properties essentially comparable to those of the Dutch, German, Italian, and United States reference samples. The sample distribution was fitted to a mathematical function and it was found it conforms to a Weibull distribution. Three preliminary explanations for this finding are considered. The elevated sample mean suggests Mexicans may have an elevated ability to engage in hypnotic behavior, thus they would likely be especially good candidates for hypnotherapeutic interventions such as those elucidated by Barabasz and Watkins (2005) that would better the health options currently available. |
