The Relationship between ABO Blood Groups and Hypnotic Susceptibility

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.
