Cross Cultural Adaptation, Reliability and Validity of the Persian Version of the University of Wisconsin Running Injury and Recovery Index

Abstract

Abstract Background The University of Wisconsin Running Injury and Recovery Index (UWRI) was developed to evaluate running ability after a running-related injury. The aim of this study was to translate and cross-culturally adapt the UWRI into Persian (UWRI-Persian) and to investigate its psychometric properties in patients with a running-related injury. Methods The UWRI-Persian was translated using the Beaton guidelines. One-hundred-and-seventy-three native Persian patients with running-related injuries were participated. The convergent validity of the UWRI-Persian was evaluated using the Pearson correlation with the pain self-efficacy questionnaire (PSEQ), Tampa scale for Kinesiophobia (TKS), and visual analogue scale (VAS). Test-retest reliability was tested among 64 patients who completed the form again after seven days. Results The UWRI-Persian showed excellent internal consistency for total score (α = 0.966). An excellent internal consistency (α = 0.922) was shown for psychological response and good internal consistency (α = 0.887) for running progression. The interclass correlation coefficient for the UWRI-Persian total scores was 0.965 (95% CI, 0.942 to 0.979), indicating high intra-rater reliability. The UWRI-Persian demonstrated a moderate correlation with the PSEQ (r = 0.425) and the TSK (r = 0.457). The UWRI-Persian showed a weak correlation with the VAS (r = 0.187). These findings suggest no floor or ceiling effects. Conclusions The UWRI is a reliable and valid tool for Persian-speaking patients with running-related injuries. The UWRI was successfully translated from English to Persian and demonstrated good to excellent internal consistency, validity and reliability with no floor or ceiling effects.
