Postoperative recovery is a complex process influenced by various factors such as patients, surgical methods and anesthetic properties. Such factors can be accompanied by many negative situations. Previous studies evaluating recovery following anesthesia primarily evaluated the incidence of morbidity, mortality, adverse anesthesia-related outcomes, and changes in vital signs (1-4). These parameters are important, but the quality of recovery of patients has been neglected in most studies. Therefore, various patient-reported outcome measurement scales and tools have been developed (1,3-8). One of these scales is Stark et al. It is the QoR-15 questionnaire developed by in 2013 (4). QoR-15 aims to assess the quality of early recovery and emotional health of patients after surgery (4,6). It is a 15-item questionnaire assessing the patient's emotional state, physical comfort, psychological support, physical independence and pain. This one-page QoR-15 questionnaire has been shown to be highly valid and reliable in patients who have undergone general surgery (4).

QoR-15 has been verified and translated into many languages such as Japanese, French, Portuguese, Chinese, Swedish (13-17). It was reported in a systemic review that all translated versions of the QoR-15 had sufficient validity and reliability to assess the quality of postoperative recovery (19). However, an official Turkish version of the QoR-15 has not yet been developed or approved.

The aim of this study was to develop the Turkish version of the QoR-15 (QoR-15T) and to evaluate its validity, reliability and responsiveness for Turkish-speaking patients receiving general and regional anaesthesia.
