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.
To examine the test-retest reliability, internal consistency, and construct validity of the EFMI.
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.
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.
The results demonstrate that the French-Canadian version of the EFMI is a unidimensional tool with excellent test-retest reliability.
下肢功能量表于2006年被翻译成加拿大法语版本；翻译后的版本名为下肢功能量表（EFMI）。尚未对EFMI的结构效度和信度进行检验。
检验EFMI的重测信度、内部一致性和结构效度。
34名接受过下肢手术或受伤的参与者在住院初期接受初步评估后，被要求填写一份人口统计学调查问卷并完成EFMI。他们在72小时内再次完成EFMI。选择组内相关系数（ICC）和kappa系数来检验EFMI的重测信度，并计算克朗巴赫α系数以评估内部一致性。进行因子分析以通过确定结构的数量及其含义来检验结构效度。
ICC值为0.92（95%CI：0.88 - 0.96），克朗巴赫α系数为0.95（95%CI：0.91 - 0.99）。因子分析表明，EFMI的所有要素共享一个主要结构。
结果表明，加拿大法语版的EFMI是一种具有出色重测信度的单维工具。
