Introduction:
The Lower Extremity Functional Scale was translated into Canadian French in 2006; the translated version was titled Échelle fonctionnelle des membres inférieurs (EFMI). The construct validity and reliability of the EFMI have not been examined.
Objective:
To examine the test-retest reliability, internal consistency, and construct validity of the EFMI.
Methodology:
Thirty-four participants who had undergone surgery or had an injury to the lower limb were asked to fill out a demographic questionnaire and complete the EFMI after their initial assessment while hospitalized. They completed the EFMI a second time within 72 hours. The intra-class correlation coefficient (ICC) and the kappa coefficient were chosen to examine the test-retest reliability of the EFMI, and Cronbach's alpha coefficient was calculated to assess internal consistency. A factor analysis was conducted to examine construct validity by determining the number of constructs and their meanings.
Results:
The ICC value was 0.92 (95% CI: 0.88-0.96), and Cronbach's alpha was 0.95 (95% CI: 0.91-0.99). The factor analysis revealed that all elements of the EFMI share one principal construct.
Conclusion:
The results demonstrate that the French-Canadian version of the EFMI is a unidimensional tool with excellent test-retest reliability.
