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 (α = 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.
