Translation and Validation of the Korean Version of the Postoperative Quality of Recovery Score QoR‐15

Quality of recovery after anesthesia is an important measure of the early postoperative health status of patients. The Quality of Recovery‐15 (QoR‐15) questionnaire is a self‐rated questionnaire used to assess the quality of postoperative recovery. This study is aimed at translating and validating the Korean version of QoR‐15 (QoR‐15K). One hundred fifty patients were included in this study. We translated the original version of QoR‐15 into QoR‐15K and evaluated its validity, reliability, responsiveness, and clinical feasibility. QoR‐15K showed acceptable criterion, structure, and construct validities. Reliability was verified using Cronbach’s α (0.856), standard error of measurement (10.78), split‐half reliability (0.831), test‐retest reliability ( ρ = 0.945, P ≤ 0.001), and intraclass correlation test‐retest ( ρ = 0.903, P ≤ 0.001). These results represent an acceptable reliability. Responsiveness was verified using Cohen’s effect size (1.39), standardized response mean (1.03), and the correlation between QoR‐15K score and duration of anesthesia ( ρ = −0.197, P = 0.016). These results show acceptable responsiveness. The mean ± standard deviation time to complete QoR‐15K was 138.1 ± 30.7 s. QoR‐15K was rated more than adequate on the COnsensus‐based Standards for the selection of health Measurement INstruments checklist. In conclusion, QoR‐15K shows acceptable validity, reliability, responsiveness, and clinical feasibility and may help evaluate postoperative quality of recovery in Korean populations.
