Correlational research has been undertaken to explain the purpose of the association between ABO blood groups and hypnotic susceptibility. The Stanford Hypnotic Susceptibility Form (Form C), modified by John F Kilhstrom, with a Cronbach’s alpha coefficient of 0.95, was used to determine the associations between blood groups and susceptibility. In this study, a clustered random-sampling method was used to investigate the relationship between hypnotic susceptibility and blood-group type, using the Spearman Correlation Coefficient. The results indicate a statistically significant correlation, with a sample size of 40 (n=40), resulted in HS (Hypnotic Susceptibility) to be medium (x= 2.53), and a mean blood group of 2.40 (SDHS: 0.50; SDABO:1.33). The results and hypothesis are described, and support the suggestion of a strong association between blood groups and hypnosis.
