Abstract Aim The aim of this study was to perform a cross-cultural adaptation and psychometric evaluation of the Quality of Recovery 15 questionnaire in Turkey.Methods The QoR-15 was translated into Turkish through a rigorous process involving independent translations, consensus, back-translation, and review. The questionnaire was administered to patients undergoing elective major gastrointestinal surgery preoperatively and on postoperative days 1, 7, and 30. Reliability was assessed using Cronbach's α and intra-class correlation coefficient. Construct validity was evaluated through confirmatory factor analysis, and responsiveness was analyzed using Cohen's effect size and standardized response mean.Results A total of 510 patients participated in the study. The Turkish version of QoR-15 (QoR-15T) demonstrated good internal consistency with Cronbach's α of 0.896 and 0.888 for preoperative and postoperative administrations, respectively. Intra-class correlation coefficient values indicated good reliability. Confirmatory factor analysis confirmed the construct validity of QoR-15T. QoR-15T showed responsiveness to changes in health status, with Cohen's effect size and standardize response mean indicating its ability to detect clinically important changes.Conclusion The Turkish version of QoR-15 (QoR-15T) is a reliable, valid, and responsive questionnaire for assessing the quality of recovery in patients undergoing major abdominal surgery. Its ability to capture patients' perspectives and multidimensional aspects of recovery makes it a valuable tool for clinical and research purposes.
