Intercultural Adaptation and Validation of the Ukrainian Quality of Recovery-15 Questionnaire

March 30, 2026 updated by: Rostyslav Voloshchuk
The Quality of Recovery 15-questionnaire (QoR-15) is used to assess postoperative quality of recovery after surgery and anesthesia from the patient's perspective. It evaluates five dimensions including pain, physical comfort, physical independence, psychological support, and emotional state. The aim of this study is to validate a Ukrainian version of the QoR-15 scale (QoR-15Ukr) to measure postoperative recovery in Ukrainian-speaking patients.
