Translation, cross-cultural adaptation and psychometric evaluation of the Greek version of the Western Ontario Meniscal Evaluation Tool (WOMET)

Abstract

Background

The Western Ontario Meniscal Evaluation Tool (WOMET) is a questionnaire designed to evaluate the health-related quality of life (HRQoL) of patients with meniscal pathology. The purpose of this study is to culturally adapt and validate the WOMET into Greek using the COSMIN checklist.

Materials and Methods

One-hundred three patients (40 females, 63 males; mean age: 42.9 ± 18.5) with meniscal pathology were recruited in this study. The test-retest reliability of the WOMET was assessed with the intraclass correlation coefficient (ICC) while the internal consistency was evaluated using Cronbach’s α. The concurrent validity was assessed by evaluating the correlation among the WOMET and the Knee injury and Osteoarthritis Outcome Score (KOOS) while construct validity was assessed with Exploratory Factor Analysis (EFA).

Results

The ICC for the overall WOMET score was 0.91 while the Cronbach’s α was 0.96. WOMET was moderately to strongly correlated with the domains of the KOOS with the strongest correlation being between WOMET and Quality of Life domain (r = 0.81). EFA provided support for a two factor solution explaining the 66.2% of the total variability.

Conclusions

The Greek version of WOMET is considered a valid tool for measuring the HRQoL of Greek speaking patients with meniscal pathology.
