Mexican norms for the Stanford Hypnotic Susceptibility Scale, Form C.

Normative data for the Mexican adaptation of the Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C) 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. However, 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 that would better the health options currently available.
