摘要
目的：探讨Dualpex Plus （DP）阴道测压仪在尿失禁（UI）患者阴道测压中的内、间信度、测量误差、标准及收敛效度。设计：这是一项临床特性研究。地点：巴西大学医院。人口：102名女性UI患者。方法：阴道测压采用DP和Peritron (Pr)，顺序随机。在一周的间隔内测试评分者的信度；评价者间信度在同一天由两个不同的评价者进行测试。对每个装置的收缩感和舒适度进行评估，并用卡方检验或配对t检验进行比较。信度采用类内相关系数（ICC）评价，置信区间为95%。标准效度（带有Pr）和收敛效度（带有牛津分数）通过Pearson’s相关性进行评估。计算了测量的标准误差（SEM）和最小可检测变化。主要结果测量：内部和内部的可靠性，测量误差和标准，以及Dualpex Plus的收敛效度。结果：DP具有较高的评分者间信度和优异的评分者内信度(ICC = 0.85；95% CI分别为0.76-0.91和0.90；95% CI分别为0.86-0.93)；强效度和正效度(r = 0.83；p 2 o;2 o p。DP比Pr更舒适，Pr的收缩感更高。结论：Dualpex Plus具有足够的临床性能。测量误差被认为是可疑的。DP比Pr更舒适，Pr对收缩的感知更高。
Intra- and Inter-Rater Reliability, Measurement Error and Criteria and Convergent Validities of the Dualpex Plus for the Vaginal Manometry of Pelvic Floor Muscles in Women With Urinary Incontinence.
Objective: To test the Intra- and inter-rater reliability, measurement error and criteria and convergent validities of the Dualpex Plus (DP) for vaginal manometry in women with urinary incontinence (UI).
Design: This is a clinimetric properties study.
Setting: University Hospital in Brazil.
Population: One hundred and two women with UI.
Methods: Vaginal manometry was performed with DP and Peritron (Pr), in a random order. Intra-rater reliability was tested within a 1-week interval; inter-rater reliability was tested on the same day by two different evaluators. Perception of contraction and comfort with each device were assessed and compared with Chi-square or paired t tests. Reliability was evaluated by intraclass correlation coefficient (ICC) with a 95% confidence interval (CI). Criteria (with Pr) and convergent (with Oxford score) validities were evaluated by Pearson's correlation. The standard error of measurement (SEM) and the minimum detectable change were also calculated.
Main outcome measures: Intra- and inter-rater reliability, measurement error and criteria and convergent validities of the Dualpex Plus.
Results: DP showed substantial inter-rater and excellent intra-rater reliability (ICC = 0.85; 95% CI 0.76-0.91 and 0.90; 95% CI 0.86-0.93, respectively); strong and positive criteria validity (r = 0.83; p < 0.001) and convergent validity (r = 0.45; p < 0.001). Pressure values for pelvic floor muscle contraction were different between DP and Pr [17.61 ± 12.22 vs. 34.91 ± 21.22 cmH2O; p < 0.001]. SEM was doubtful (19%) and the minimum detectable change was 0.152 cmH2O. DP was more comfortable than Pr and perception of contraction was higher for Pr.
Conclusion: Dualpex Plus showed adequate clinimetric properties. Measurement error was considered doubtful. DP was more comfortable than Pr and perception of contraction was higher for Pr.
