Reliability and Validity of the Chinese Version Critical Care Nurses’ Evaluation Scale of Nursing Activities for Extracorporeal Membrane Oxygenation–Supported Patients

Background: Given the lack of an instrument for evaluating nursing activities related to extracorporeal membrane venovenous oxygenation (ECMO) in intensive care settings. We then examined the psychometric properties of the critical care nurses’ evaluation scale of nursing activities for ECMO-supported patients (ECMO-SP). Methods: Utilizing the Brislin translation model and expert consultation, we translated and cross-culturally adapted the scale, then employed convenience sampling to select nurses from the intensive care units (ICUs) of 3 tertiary hospitals in Henan Province. Results: The Chinese version scale comprised 4 dimensions with 20 items, demonstrating a cumulative variance contribution of 67.76%. The content validity index (CVI) for the overall scale was 0.921, S-CVI/Ave ranging from 0.857 to 1.000. The Cronbach α was 0.945, and the Cronbach α for each dimension ranged from 0.864 to 0.919. The split-half reliability coefficient was 0.864, and the test-retest reliability (ICC) was 0.612. The scale demonstrated satisfactory convergent validity. Conclusion: The Chinese version of the scale exhibits robust reliability and validity, thus supporting its use for ECMO-SP nursing activities among ICU nurses in China.
