To determine the psychometric properties of the total Vaizey score and its individual items.
The study was conducted as part of a prospective cohort study assessing the outcome of pelvic floor rehabilitation in patients with fecal incontinence.
One hundred ninety-four patients were analyzed, 53 of whom provided data on the global perceived effect (GPE) score. Pelvic floor rehabilitation resulted in a significant reduction of the total Vaizey score and most individual items. The total Vaizey scores changed in agreement with the GPE scores. The total Vaizey score was responsive, but some individual items yielded inconsistent results for three different measures. The test-retest reliability was adequate or excellent for six individual items and the total Vaizey score. The internal consistency was low for the total Vaizey score at baseline, in contrast to the follow-up and change scores. The estimates for the minimally important change (MIC) and smallest detectable change yielded moderately consistent results. An MIC of -5 points seemed preferable and yielded the lowest misclassification rate.
More research is required to confirm conclusions on the psychometric properties of the total Vaizey score and its individual items, and to justify its use in research and routine clinical practice.
确定 Vaizey 总评分及其各项的心理计量学特性。
该研究是一项前瞻性队列研究的一部分，旨在评估盆底康复对粪便失禁患者的治疗效果。
对 194 名患者进行了分析，其中 53 名患者提供了总体感知效果（GPE）评分的数据。盆底康复可显著降低 Vaizey 总评分和大多数单项评分。总的 Vaizey 评分与 GPE 评分变化一致。总的 Vaizey 评分具有反应性，但在三种不同的测量方法中，一些单项评分结果不一致。六个单项评分和 Vaizey 总评分的测试-重测信度适中或良好。与随访和变化评分相比，基线时 Vaizey 总评分的内部一致性较低。最小重要变化（MIC）和最小可检测变化的估计值得出了较为一致的结果。-5 分的 MIC 似乎更可取，且错误分类率最低。
需要进一步研究来证实 Vaizey 总评分及其各项的心理计量学特性的结论，并证明其在研究和常规临床实践中的使用是合理的。
