Abstract
INTRODUCTION: Cardiopulmonary resuscitation (CPR) is one of the most stressful situations in emergency medicine, where nurses play a central role and are exposed to significant levels of stress. Among the factors that can maintain team cohesion and performance, enabling effective adaptation to changes, risk factors, and stressors, is nursing team resilience. The present study aimed to conduct a Persian translation and psychometric evaluation of the Nursing Team Resilience Scale in the context of cardiopulmonary resuscitation. METHODS: This cross-sectional methodological study was conducted between June 2024 and March 2025 in Gonabad and Bajestan in Iran, on 360 nurses using convenience sampling method. For translation process, the Forward-Backward method was used. Face validity was performed on 10 nurses, and the opinions of 10 experts in the field of nursing and psychometrics of the tool were used for content validity, and CVR and CVI values were calculated. Construct validity was examined using exploratory factor analysis (sample: 160) and confirmatory factor analysis (sample: 200).To assess reliability, two indices were calculated: internal consistency reliability (Cronbach’s alpha) and intraclass correlation coefficient (ICC). Data analysis was performed using SPSS version 22 and AMOS version 24. RESULTS: No items were removed during the face and content validity assessments; only minor revisions were applied. the Kaiser-Meyer-Olkin (KMO) index was found to be 0.76, indicating adequate sampling adequacy. The result of Bartlett’s test of sphericity was significant (χ² = 298.29, df = 28, p < 0.001), confirming the suitability of the data for factor analysis. In Exploratory factor analysis, 2 factors were extracted that explained 41.29% of the total variance. Confirmatory factor analysis (CFA) demonstrated good fit for the two-factor model (AGFI = 0.911, CFI = 0.938, PCFI = 0.637, RMSEA = 0.071, PNFI = 0.602, GFI = 0.953, IFI = 0.940, and RMR = 0.040). The Cronbach’s alpha coefficient for the entire questionnaire was 0.75 and the intraclass correlation coefficient (ICC) was 0.95. CONCLUSION: The results of the present study demonstrated that the Persian version of Nursing Team Resilience Scale in the context of cardiopulmonary resuscitation has satisfactory validity and reliability. This instrument demonstrates strong potential for use as a standardized tool in assessing nursing team resilience among Iranian nurses, particularly in high-stress settings like CPR.
