Psychometric Analysis of the Spanish Version of the Évaluation du Vécu de l’Anesthésie Générale EVAN-G Questionnaire in Adult Surgical Patients in Argentina: A Cross- Sectional Study

Background Patient satisfaction during the perioperative period involves multiple facets of care. Despite its clinical relevance, validated tools to assess patient satisfaction in Spanish-speaking populations are scarce. The Évaluation du Vécu de l’Anesthésie Générale questionnaire, originally developed in French and subsequently adapted to Spanish, offers a comprehensive framework for evaluating perioperative satisfaction. Methods A cross-sectional study was conducted at a tertiary private hospital in Buenos Aires. We performed a psychometric evaluation including confirmatory factor analysis, assessment of convergent and discriminant validity, and internal consistency analysis. Results The model showed acceptable global fit indices: Root Mean Square Error of Approximation (0.073), Comparative Fit Index (0.956), and Tucker-Lewis Index (0.951). Most dimensions—information, privacy, discomfort, waiting, and care—demonstrated strong validity (Average Variance Extracted ≥ 0.50) and reliability (Composite Reliability ≥ 0.70). However, the Pain dimension exhibited suboptimal performance, with low validity and reliability. Conclusions The Spanish version of the Évaluation du Vécu de l’Anesthésie Générale questionnaire is an effective tool for measuring patient satisfaction across most dimensions. However, challenges in the Pain dimension highlight the need for refinement in this area or the potential use of a different tool to assess it more accurately. These findings present this questionnaire as an innovative tool for promoting patient-centered care in Latin America, meeting a vital need for culturally tailored measures of perioperative satisfaction
