Translation and Validation of the American Pain Society–Patient Outcome Questionnaire (Revised) into Arabic

Background: Effective assessment of acute postoperative pain is essential for optimising postoperative outcomes. The American Pain Society Patient Outcome Questionnaire-Revised (APS-POQ-R) is a widely recognised instrument for evaluating the quality of postoperative pain management, yet its use among Arabic-speaking patients remains limited by the lack of a validated translation. The present study aimed to systematically translate and validate the APS-POQ-R for use in Arabic-speaking surgical populations, following international guidelines for instrument adaptation.
