Development of the Spanish Version of 'Nurses' Perceptions of Responsibility, Knowledge and Documentation Focusing on Enteral Nutrition and Nursing Practice Regarding Enteral Feeding in the Intensive Care Unit'

Background: Adequate nutritional knowledge among intensive care nurses is essential for early identification of nutritional risk and prevention of complications in critically ill patients. The questionnaire 'Nurses' perceptions of responsibility, knowledge and documentation focusing on enteral nutrition and nursing practice regarding enteral feeding in the intensive care unit', developed by Persenius et al., is used internationally, yet no culturally adapted Spanish version has been available. Objectives: This study aimed to translate and culturally adapt Persenius et al.'s questionnaire and evaluate its content for use among Spanish-speaking intensive care unit (ICU) nurses. Materials and methods: A multistep process was conducted, including forward-backward translation, expert review by an expert panel of ICU nurses (N = 26) with at least 2 years of critical care experience, and content validity analysis. Experts rated item relevance and comprehensibility. Item Content Validity Index (I-CVI), Scale CVI, and Aiken's V were calculated using predefined thresholds. Linguistic clarity/comprehensibility was assessed on a 5-point Likert scale (1-5). To assess the questionnaire's reliability, Cronbach's alpha was also analysed in a pilot study (N = 99). Results: The Spanish version retained all 47 original items after minor linguistic adjustments. All items met the minimum content validity threshold; most showed I-CVI values > 0.78 and acceptable Aiken's V coefficients. The mean comprehensibility score for all items exceeded 4.0, indicating high clarity. No item required significant semantic modification after expert review. Cronbach's alpha coefficient of 0.85 reflected its reliability. Conclusions: The Spanish version of Persenius et al.'s questionnaire demonstrated adequate content and linguistic validity and internal consistency in a pilot sample of ICU nurses.
