Background Emotional intelligence (EI) refers to a person’s ability to acknowledge the feelings of oneself and others, and to control those feelings so as to behave in a socially acceptable manner. We investigated the relationships between the characteristics of EI among nurse managers, and their perceptions of how much their position’s roles and responsibilities can be delegated to other staff members.

Methods We surveyed 150 nurse managers working at 30 hospitals by using an anonymous questionnaire. The questionnaire consists of basic attributes, EI and work perception. The emotional intelligence scale (EQS) domain scores were analyzed by means of one-way repeated-measures analysis of variance. EQS scores were compared with corresponding averages for working adults in the instructions. The perceived importance of duties of nurse managers was compared between the resulting EQS scores ‘High’ and ‘Low’ groups.

Results The analysis population consisted of 105 nurse managers. Their EQS scored higher in all three domains, and with the exception of Altruism for all factor scores than the average for working adults. The perceived importance of the typical duties of nurse managers were compared between the High and Low groups for each EQS domain. Significant differences were observed between nurse managers with High and Low Intrapersonal emotional quotient (EQ) on four tasks. No significant differences were found for any of the responsibilities when nurse managers with High and Low Interpersonal EQ or Situational EQ were compared.

Conclusion The nurse managers’ average EQS scores were higher in all areas. The high scores that were exhibited by could be considered desirable qualities for nurse managers. It seemed nurse managers with high scores in intrapersonal EQ struck a good balance between placing importance on EI considerations like managing relationships and creating a comfortable workplace, and management and leadership behaviors like department management and operations and data management.
