Validity and reliability study of the quality of recovery scale in Turkish

Background/aim: The aim of this study was to adapt the "Quality of Recovery-15 Scale", developed to measure the postoperative recovery quality of individuals, into Turkish by carrying out validity and reliability studies.Materials and methods: This methodological study was conducted with a total of 150 patients who underwent surgery under general anesthesia between November 2021 and January 2022 in a training and research hospital in the Black Sea region. Data was collected from the patients through the face-to-face interview method before the operation, on the 24th and the 48th hour postoperatively. First, the linguistic validity of the scale and then the validity and reliability analyses were carried out. Construct validity, confirmatory factor, and reliability analyses were then performed. Results: The Cronbach's alpha coefficient of the scale was 0.851. The Kaiser-Meyer-Olkin test for goodness of fit of the one-dimensional 14-item scale was 0.853 and Bartlett's test was significant. The goodness of fit values of the scale were found to be RMSEA = 0.149, CFI = 0.769, and GFI = 0.745, and they were considered acceptable levels. The eighth item was removed from the scale, which had originally consisted of 15 items, because the item correlation coefficient of this item was <0.200. Conclusion: The "Quality of Recovery Scale" was found to be a reliable and valid scale that can be used to measure the quality of recovery after surgery in Turkish society.
