Validity and Reliability of the Turkish Version of the Postoperative Fatigue Scale

Objective: Postoperative fatigue is an undesired and discouraging symptom that many patients experience after the surgery operation. Good assessment is essential to detect and manage this symptom. There is no specific Turkish validity and reliability measurement tool to assess postoperative fatigue. In this study, it was conducted to adapt the Postoperative Fatigue Scale (PO-FS) to Turkish in order to evaluate postoperative fatigue. Methods: Methodological study method was applied. This study was conducted with a total of 276 patients. The data of the study were collected using the personal information form, PO-FS and Visual Analog Scale-Fatigue in April-July 2019. Results: PO-FS sub-scales fatigue, vigor, and daily life activities have Cronbach's alpha coefficient of 0.873, 0.898, and 0.815, respectively. The factorial analysis revealed that three factors explain 76.344% of the total variance. These findings suggest that Turkish version of PO-FS is a valid and reliable scale. Conclusion: PO-FS's Turkish translation is valid and can be reliably used for determining the postoperative fatigue of patients.
