Abstract
BACKGROUND: Nursing is considered one of the most stressful occupational groups. Work-related stress is a major health risk for workers worldwide. Therefore, it is critical to continually monitor nurses' stress levels based on important aspects of nurses' work identified as stressors. METHODS: A total of 331 nurses participated. The cross-cultural adaptation of the instrument was carried out based on six of the seven steps proposed: forward translation of ENSS, comparison of the two translated versions, blind back translation, comparison of the two back-translated versions of ENSS, pilot testing of the prefinal version of ENSS, and full-psychometric testing of the prefinal version of the translated instrument. The reliability of the scales was estimated using Cronbach's alpha and McDonald's omega internal consistency coefficients. RESULTS: The results indicate that each of the distinguished subscales is unique, but at the same time, they are all related to each other as different dimensions of stress. CONCLUSIONS: The Polish version of the ENSS tool is a valid and reliable tool for assessing the level of stress experienced by nurses.
