Emotional Intelligence as Critical Competence in Nurses' Work Performance: A Cross-Sectional Study.

Background/objectives: Emotional intelligence may help nurses to cope with demanding work environments where the need to improve the quality and safety of the care provided, as well as the care of the chronically ill, prevails. Although it is well known that emotional intelligence is positively related to work performance, the literature on nurses is limited. The aim of our study was to examine the impact of emotional intelligence on work performance in a sample of nurses in Greece.

Methods: We conducted a cross-sectional study with 318 nurses. We collected data from a convenience sample of nurses during January 2024. Since we conducted an online survey through social media, our sample could not be representative of all nurses in Greece. For instance, older nurses may be underrepresented in our study due to limited access on social media. We measured emotional intelligence with the Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF) and work performance with the Individual Work Performance Questionnaire (IWPQ). We created multivariable linear regression models adjusted for sex, age, educational level, and work experience. We followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

Results: We found that the four streams of emotional intelligence (i.e., well-being, self-control, emotionality, sociability) increased nurses' work performance. In particular, we found a positive relationship between well-being and task performance (adjusted beta = 0.210, 95% CI = 0.140 to 0.281, -value < 0.001) and contextual performance (adjusted beta = 0.135, 95% CI = 0.050 to 0.221, -value = 0.002). Similarly, there was a positive relationship between self-control and task performance (adjusted beta = 0.136, 95% CI = 0.030 to 0.241, -value = 0.012). Additionally, sociability increased task performance (adjusted beta = 0.223, 95% CI = 0.151 to 0.295, -value < 0.001) and contextual performance (adjusted beta = 0.198, 95% CI = 0.111 to 0.286, -value < 0.001). Moreover, emotionality (adjusted beta = -0.198, 95% CI = -0.319 to -0.076, -value = 0.002) and sociability (adjusted beta = -0.133, 95% CI = -0.221 to -0.044, -value = 0.003) reduced counterproductive work behavior.

Conclusions: Our multivariable models identified a positive impact of emotional intelligence on nurses' work performance. Nurse managers and healthcare organizations should adopt appropriate interventions to improve nurses' emotional intelligence. Enhancing emotional intelligence among nurses can improve work performance and, thus, healthcare outcomes. Moreover, higher levels of emotional intelligence may empower nurses' compassion and resilience, fostering a supportive work environment. In this context, the well-being of both nurses and patients may improve.
