Evaluation of occupational stress and job performance in Iranian nurses: the mediating effect of moral and emotional intelligence

Background Nurses' Job performance could be affected by occupational stress. Previous studies reported contradictory results in this regard. Factors such as moral and emotional intelligence could impact occupational stress. However, the extent of any mediating effect is unclear. Thus, this study aimed to determine the effect of occupational stress on nurses' Job performance and the mediating impact of moral and emotional intelligence.Methods This cross-sectional study was conducted in Urmia teaching hospitals (Imam Khomeini, Motahari, Taleghani, Kosar, and Seyed al-Shohada Hospitals). Six hundred twenty-one nurses were selected using quota sampling from February 2022 to April 2022. Data were collected using demographic questionnaires, the Nursing Stress Scale, Paterson's Job Performance Questionnaire, Siberia Schering's Emotional Intelligence Standard Questionnaire, and Lennik and Keil's Moral Intelligence Questionnaire. Data were analyzed using SPSS ver. 23 and SmartPLS ver. 2.Results Occupational stress had a positive, direct, and minor effect on nurses' job performance (beta = 0.088, t-value = 2.245, p < 0.01). Occupational stress had a positive and direct impact on moral intelligence (beta = 0.161, t-value = 2.945, p < 0.01) and a negative and direct effect on emotional intelligence (beta = -0.351, t-value = 7.484, p < 0.01). Occupational stress negatively and indirectly affected job performance through moral intelligence (beta =-0.560, t-value = 14.773, p < 0.01). Occupational stress also positively and indirectly impacted job performance through emotional intelligence (beta = 0.098, t-value = 2.177, p < 0.01).Conclusions Occupational stress slightly affects nurses' job performance, and emotional and moral intelligence mediates the impact of occupational stress and improves nurses' job performance. Low occupational stress improves nurses' job performance, but too much occupational stress could harm nurses' job performance. Healthcare administrators should work to help reduce nurses' occupational stress and improve their job performance by adopting practical strategies to help nurses manage and control their stress. Holding stress reduction classes, eliminating the nursing shortage, reducing working hours, reducing workload, and providing financial and spiritual support to nurses would be recommended. It is also recommended to provide theoretical and practical emotional and moral intelligence-oriented courses for nursing students and hold training workshops for nurses to improve their emotional and moral intelligence.
