Emotional intelligence and communication efficiency of nurses Study aim: The aim of this study is to evaluate the level of emotional intelligence of nurses/technicians employed at KBC Osijek and the forms of their everyday communication as well as how successful it is. Moreover, the aim is to determine whether there are significant differences among respondents in relation to age, gender, level of education and length of service. Structure of the study: Cross-sectional research. Participants and methods: Participants in this study are nurses and technicians employed at KBC Osijek. The study involved 65 employees of the Surgery Clinic and the Psychiatric Clinic. An anonymous questionnaire was used to conduct the research, the first part of which is general data such as age, gender, level of education and length of service. The second part consists of the Emotional Competence Questionnaire by Vladimir Takšić (UEK – 45), and the last part consists of the Interpersonal Communication Skills Questionnaire (Learning Dynamics 2002). Results: Most of the participants are women – 86,15 %, while 13,85 % is men. People from 20 to 62 years of age have participated in this study, and most of them are young people. Accordingly, the highest number of persons included are those with the least years of service. The participants have shown the best skills in managing their emotions. Women have achieved a significantly better result in the sub-scale Expressing and naming emotions. By analysing the answers to the Interpersonal Communication Skills Questionnaire in relation to the demographic data of the participants, no statistically significant differences were found in the study, nor the correlation of the response to the age and length of service. A statistically significant limit value can be seen in relation to gender in the sub-scale Giving and receiving feedback. Women are more successful in this area. Conclusion: Analysis of the participants’ responses found that they are best able to manage emotions, and worst in expressing and naming emotions. It has also been found that women are better at expressing and naming emotions. There is no correlation between success in communicating and age, level of education, and length of service. However, it has been found that women are more successful in giving and receiving feedback during communication.
