Cross-cultural adaptation and evaluation of the psychometric properties of the University of Wisconsin Running Injury and Recovery Index questionnaire in Spanish (UWRI-S)

Objective: To cross-culturally adapt and evaluate the psychometric properties of the University of Wisconsin Running Injury and Recovery Index questionnaire in Spanish (UWRI-S) in Chilean runners with a running-related injury. Design: Cross-cultural adaptation and validation study, following the Consensus-based Standards for selecting health Measurement Instruments (COSMIN) recommendations. Setting: Outpatient sports medicine clinic and running clubs. Participants: UWRI was forward and backward translated, and culturally adapted. Thirty-one runners participated in the content validity of the UWRI-S; and fifty-seven in the assessment of psychometric properties. Main outcome measures: Runners seeking care from a physiotherapist completed the UWRI-S (baseline and after 48-72 h for reliability), Lower Extremity Functional Scale (LEFS), Patient Specific Functional Scale (PSFS), Global Rating of Change scale (GROC), and Numeric Pain Rating Scale (NPRS). Results: Suggestions about accuracy of wording and understanding of items were incorporated. UWRI-S showed a positive moderate correlation with LEFS (r = 0.6; p < 0.05), positive fair with GROC (r = 0.5, p < 0.05), negative fair with NPRS (r =-0.4; p < 0.05) and no correlation with PSFS (r = 0.3; p = 0.1). UWRI-S demonstrated acceptable internal consistency (a = 0.87) and test-retest reliability (ICC = 0.87). Conclusion: UWRI-S is a valid and reliable measure to evaluate running ability of Chilean runners during recovery from a running-related injury. (C) 2022 Elsevier Ltd. All rights reserved.
