ABSTRACT
Background: Emotional intelligence (EI) can be described by means of capabilities possessed by a person
to recognize feeling, and to manage emotions. For instance, active types of blood are O and B i.e. they are
(belligerent and developing) On the other hand blood types A and AB are submissive i.e. (unchanging and
unprogressive). The study aimed to find out the association between emotional intelligence and blood
groups.
Methods: A cross sectional study was carried out on 184 male and female students of a private university,
Karachi. Blood group of these subjects was determined by using hematological and aseptic techniques and
samples were collected through finger prick method acknowledged by the students. Results were recorded
by applying the Fisher’s exact test and one way ANOVA to see the significance.
Results: Self-awareness having highest mean score in O- group 17.00±1.00 with p-value of 0.011. In empathy
blood group A+20.20±3.22 and O- 20.00±1.73 achieved highest mean values with p-value of 0.000, self-moti-
vation level also got highest mean score in O- group 23.67±3.51with p-value of 0.035, managing relations
level was highest observed in O- group 17.00±1.73 with p-value of 0.001. In addition, altruistic behavior found
positive in O- blood group 8.67±0.58 with significant p-value of 0.000 among all students.
Conclusion: Blood groups were identified significantly with different emotional intelligence level. The
students having blood group O found to be more emotionally intelligent. However, large-scale studies are
required in different parts of the world to explore the new aspects.
