Quality of recovery (QoR) is a significant component of peri-operative health status and is influenced by patients' characteristics and surgical and anesthetic methods. The QoR-15 scale is a patient-reported outcome questionnaire that measures postoperative QoR. The validity of the QoR-15 scale has been proven in many languages. In this study, we aimed to translate the QoR-15 questionnaire into Turkish and evaluate its validity in the Turkish population. After being translated into Turkish, the questionnaire was administered to 190 patients who underwent obstetric, gynecological, orthopedic, or thoracic surgery under general or regional anesthesia. The Turkish version of QoR-15 (QoR-15T) was administered 2 times: before surgery and 24 hour after surgery. The feasibility, reliability, validity and responsiveness of the QoR-15T were evaluated. Because 13 patients were discharged within 24 hour postoperatively, the study was completed with 177 patients. The recruitment and completion rates of questionnaire were 95% and 93.1% respectively. The completing time of the questionnaire was 2.5 minutes preoperatively and 3.5 minutes postoperatively. The scale yielded a Cronbach α value of 0.75, a Cohen effect size of 1.42, and a standardized response mean of 1.39. There was a significant positive correlation (95% confidence interval; R = 0.68, P < .001) between QoR-15T and visual analog scale postoperatively. The correlation of the items with the total QoR-15T score ranged from 0.19 to 0.60. The total scores of preoperative and postoperative QoR-15T were mean: 130.67, standard deviation: 15.78 and mean: 108.23, standard deviation: 13.06, respectively, with a significant difference between them (P < .01). The QoR-15T is feasible, reliable, valid, and responsive among patients undergoing surgery under general and regional anesthesia.
