Psychometric Properties of Persian Version of Condensed Nurses' Occupational Stress Scale in Covid-19 Pandemic Period

Background and Objective: Nursing is recognized in all countries as a job with high occupational stress. Therefore, the existence of tools to assess this occupational stress can contribute research into nurses’ mental health. The aim of this study was to investigate the psychometric properties of Persian version of the Condensed Nurses' Occupational Stress Scale (NOSS). Material and Methods: In this cross-sectional study, 224 nurses working in two hospitals in Shiraz, Iran, which were chosen as care centers for patients with coronavirus, were selected by convenience sampling method and completed the Condensed Nurses' Occupational Stress Scale. SPSS 22 and AMOS software were used to analyze the data. Results: The results of exploratory factor analysis using principal components method and confirmatory factor analysis confirmed the two-factor structure of “stresses related to environmental-organizational factors” and “stresses related to high workload’ in the Persian version of the Nurses' Occupational Stress Scale. In addition, Chronbach’s alpha and McDonald omega were used to determine internal consistency, Chronbach’s alpha and McDonald's omega coefficients for the whole scale (α: 0.94 and ω: 0.95) and two subscales of “stresses related to environmental-organizational factors” (α: 0.91 and ω: 0.91) and “Stresses related to high workload” (α: 0.90 and ω: 0.91) were within acceptable limits. Conclusion: Condensed Nurses' Occupational Stress Scale has acceptable psychometric properties in Iranian society and can be used as a useful tool in research related to nurses' occupational stress.
