The Quality of Recovery-40 questionnaire (QoR-40) is a self-rated questionnaire used to assess the postoperative recovery quality and health status of patients in the early stages following surgery; however, there is no Turkish version of the QoR-40. The aim of this study was to assess the reliability, validity, and responsiveness of the Turkish version of the QoR-40 (QoR-40 T).


After the approval of the ethics committee, a total of 137 patients completed the questionnaire during the preoperative period, on the third day, and one month after surgery. The quality of life was evaluated by using a health-related quality of life questionnaire (Short-Form Health Survey-36; SF-36) on the third day and one month after surgery. Reliability, feasibility, and validity were assessed to validate the QoR-40 T.


The Cronbach's alpha of the global QoR-40 T on the third day after surgery was 0.936. A positive moderate correlation was obtained between the physical comfort, emotional state, physical independence, and pain dimensions of the QoR-40 T and the physical component summary, mental health, physical functioning, and bodily pain subscales of the SF-36 on the third day after surgery, respectively (physical comfort - physical component summary, ρ = 0.292, p = 0.001; emotional state - mental health, ρ = 0.252, p = 0.003; physical independence - physical functioning, ρ = 0.340, p < 0.01; pain - bodily pain, ρ = 0.381, p < 0.01). The standardized responsive mean of the total QoR-40 T was 0.62.


The QoR-40 T showed satisfactory reliability and validity in evaluating the quality of recovery after surgery in the Turkish population.
