Validation of the Turkish version of the quality of recovery-40 questionnaire

Abstract

BackgroundThe 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).MethodsAfter 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.ResultsThe 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.ConclusionsThe QoR-40 T showed satisfactory reliability and validity in evaluating the quality of recovery after surgery in the Turkish population.

“…(14) The QoR-40 responsiveness in other cultures was investigated between measures of pre-and postoperative periods, obtaining similar results -a moderate to significant effect. (15)(16)(17)(18) When investigating long term responsiveness, measurement between pre-and postoperative (90 days) of patients submitted to neurological surgeries, Australian researchers identified the QoR-40 good ability in detecting recovery changes (SRM>0.80). (19) The recovery monitoring over time showed that in the second return (about seven months after surgery), the QoR-40 scores were higher than the ones found in the preoperative period, characterizing an improvement in health status identified by the instrument.…”

“…In Turkey, the internal consistence of the total was 0.93, with a variation in dimensions of 0.82 to 0.92; in Iran, alpha was 0.89 for the total, and 0.89 to 0.93 for dimensions; in Japan, it was 0.91 for the total and 0.74 to 0.88 for dimensions. (3,16,18) Despite the questionnaire's acceptable reliability, items that might have interfered negatively in the results were identified. Items that investigate skills of communication and self-care did not receive variability of responses (preoperative and second return), i.e., all patients pointed to the best response.…”

“…(3,5,18,20) The correlation of the QoR-40 with the VAS of surgical recovery was acceptable and superior when compared to values obtained in other cultures, whose results ranged from r=0.45 to 0.68. (3,5,15,16,18,19) …”

Comparison of Patient Satisfaction Between General and Spinal Anaesthesia in Emergency Caesarean Deliveries

“…In our study, the investigator applied the questionnaire. The Turkish version of QoR-40 has been tested for validity and reliability (12). Cronbach-α values were suitable for our study group.…”

“…The Quality of Recovery-40 (QoR-40) scale evaluates the quality of recovery postoperatively, and the Turkish form has been shown to be valid and reliable (11,12). Studies investigating the quality of recovery after general and spinal anaesthesia in emergency caesarean deliveries are scarce.…”
