BACKGROUND
The Western Ontario Meniscal Evaluation Tool (WOMET) is the only questionnaire available to assess quality of life in patients with isolated meniscal injuries. The aims of this study were to prepare the Persian version of the WOMET (PWOMET) and validate it in Iranian patients with isolated meniscal tears.
METHODS
In the first stage, the English version of WOMET was translated into Persian. Content validity, and qualitative and quantitative (impact score) face validity were tested by specialists and in a sample of 30 patients. In the second stage, PWOMET was assessed for the evaluation of psychometric properties in 100 patients with isolated meniscal injury and 50 healthy people based on the COSMIN checklist. Construct validity was tested based on structural validity (factor analysis) and hypothesis testing. Correlation with the total scores on the SF-36, IKDC and KOOS were used for concurrent criterion validity. Test-retest reliability and internal consistency were calculated using intraclass correlation coefficient (ICC) and Cronbach's alpha, respectively. In addition the standard error of measurement (SEM) and smallest detectable change were calculated. Interpretability was investigated as the ceiling and floor effects and minimal important difference.
RESULTS
The PWOMET had acceptable qualitative face validity and content validity. The impact score (quantitative face validity) was more than 1.5 for all items. For construct validity, structural validity (factor analysis) and hypothesis testing ability were confirmed. Correlations between the PWOMET total score and IKDC, SF-36, KOOS scores were 0.61, 0.54 and 0.63, respectively (p < 0.001), thus confirming concurrent criterion validity. The intraclass correlation coefficient, Cronbach's alpha, SEM and smallest detectable change for the PWOMET were 0.73, 0.89, 9.43 and 26.13, respectively. The PWOMET had no ceiling or floor effects, and minimal important difference was 9.07.
CONCLUSION
The PWOMET provides valid and reliable scores for assessment of the quality of life in patients with isolated meniscal injury.
背景
安大略西部半月板评估工具（WOMET）是评估孤立性半月板损伤患者生活质量的唯一问卷。本研究的目的是制备波斯语版 WOMET（PWOMET）并在伊朗孤立性半月板撕裂患者中验证其有效性。
方法
在第一阶段，将 WOMET 的英文版本翻译成波斯语。通过专家和 30 名患者样本对内容有效性以及定性和定量（影响评分）表面有效性进行了测试。在第二阶段，根据 COSMIN 清单，在 100 名孤立性半月板损伤患者和 50 名健康人中评估 PWOMET 的心理测量特性。结构效度通过结构效度（因子分析）和假设检验进行测试。与 SF-36、IKDC 和 KOOS 的总分相关用于同时效标效度。使用内部一致性系数（ICC）和 Cronbach 的 alpha 分别计算测试-重测信度和内部一致性。此外，还计算了测量标准误差（SEM）和最小可检测变化。通过天花板和地板效应以及最小临床重要差异来研究可解释性。
结果
PWOMET 具有可接受的定性表面有效性和内容有效性。所有项目的影响评分（定量表面有效性）均大于 1.5。对于结构效度，确认了结构效度（因子分析）和假设检验能力。PWOMET 总分与 IKDC、SF-36、KOOS 评分的相关性分别为 0.61、0.54 和 0.63（p<0.001），从而证实了同时效标效度。PWOMET 的组内相关系数、Cronbach 的 alpha、SEM 和最小可检测变化分别为 0.73、0.89、9.43 和 26.13。PWOMET 无天花板或地板效应，最小临床重要差异为 9.07。
结论
PWOMET 为评估孤立性半月板损伤患者的生活质量提供了有效且可靠的评分。
