The Italian Organizational Culture and Readiness Scale for System‐Wide Integration of EBP ( OCRSIEP ) Scale: Psychometric Adaptation of an Existing Scale

BACKGROUND: Organizational culture and readiness are critical determinants of evidence-based practice (EBP) implementation. The Organizational Culture and Readiness Scale for System-Wide Integration of EBP (OCRSIEP), developed within the ARCC framework, is a validated tool to assess these dimensions, but no Italian version currently exists. AIM: To translate, culturally adapt, and psychometrically validate the OCRSIEP and its short form in Italian. METHODS: A validation study was conducted, using exploratory and confirmatory factor analyses to derive and test the underlying model, followed by reliability testing with multiple indices and measurement invariance analyses. RESULTS: Data were collected from 405 Italian nurses. Factor analyses supported a 19-item, six-factor structure explaining 59.5% of the variance, with a second-order factor indicating an overarching construct. The three-item short form showed strong model fit and explained 67% of the variance. Subscales demonstrated acceptable-to-excellent reliability, and partial scalar invariance was established across public and private facilities. LINKING EVIDENCE TO ACTION: The Italian OCRSIEP scales are valid and reliable tools to assess organizational readiness for EBP implementation. They can guide leaders, educators, and researchers in monitoring, benchmarking, and advancing EBP-oriented system transformation within the Italian healthcare context.
