Background: Personality trait is a complex trait of an individual, which has been hypothesized to have link with diseases. It is believed that understanding personality traits of an individual can assist to prevent the diseases. Therefore, scientists are trying to explore potential factors that can predict the personality traits of an individual. Blood groups could be a potential predictor because some researchers have found a linkage between ABO genes and genes related to the development of personality traits in someone. Few studies have already found a significant relationship between blood groups and personality traits. However, there is still a paucity of researches to reach out a conclusion on this topic. Our study is another attempt to find out the possible relationship between blood groups and personality traits.
Method: The present study was a cross-sectional study which used a 50 items big-five factor personality inventory developed by Goldberg for data collection. A total of 148 participants responded to the study among them 85 participants were males and 65 were females. A two way multivariate analysis (MANOVA) was performed using IBM SPSS Statistics version 26.
Result: MANOVA results revealed neither the significant main effect of blood groups [F (15,414)=1.102, p>0.05] nor had the significant interaction effect of blood groups and gender [F (15,414)=1.111, p>0.05] on the combined dependent variables. However, this study found a significant main effect of gender on the combined dependent variables [F (5,136)=4.520, p=0.001, (1-β)=0.967, η2=0.143].
Conclusion: The present study did not support the idea that there is significant relationship between blood groups and personality traits. But, the idea that male personality significantly differs from female personality was well-supported by this study.
