The Patient-Rated Tennis Elbow Evaluation Questionnaire was successfully translated to Persian

Abstract

Introduction: The Patient-Rated Tennis Elbow Evaluation (PRTEE) is designed to evaluate pain and disability in subjects with lateral elbow tendinopathy. This questionnaire is available in Swedish, Italian, and some other languages. A Persian language version of the questionnaire is needed for both research and clinical purposes. Purpose of the Study: The purpose of this study was to translate and cross-culturally adapt the PRTEE questionnaire into the Persian language and to determine its validity and reliability. Methods: The PRTEE was translated and culturally adapted from English into Persian (PRTEE-P) according to the established guidelines. The PRTEE-P was completed by 68 Iranian subjects (44 women, 24 men) diagnosed with chronic lateral elbow tendinopathy. To assess test-retest reliability, all subjects filled out the PRTEE-P on a second admission within one week. The intraclass correlation coefficient (ICC) and Cronbach's alpha were measured to report reliability. The validity was determined by correlating the PRTEE-P questionnaire with the Persian version of the Disabilities of the Arm, Shoulder, and Hand questionnaire. Results: The Persian version of the PRTEE showed a high internal consistency with a Cronbach's alpha of 0.99, demonstrating good test-retest reliability (ICC = 0.99). It was well correlated with Disabilities of the Arm, Shoulder, and Hand (r = 0.80). Conclusion: The PRTEE-P is a reliable and valid tool designed for measuring pain and disability in subjects with lateral elbow tendinopathy. (C) 2020 Hanley & Belfus, an imprint of Elsevier Inc.
