To assess the inter-rater reliability of two raters for the mean and single maximal value of three vaginal maximum voluntary contractions (MVCs) using the Peritron™ perineometer for study participants in the first and second trimesters of pregnancy.
Thirty-six low-risk pregnant women.
The assessments were done by two different examiners with an interval of 2 to 7 days. For statistical analysis, the concordance correlation coefficient (CCC) and Bland-Altman limits of agreement were used.
For the overall sample, good reliability of 0.80 was found analyzing the mean of three MVCs and for the single maximal value (CCC = 0.79). Good reliability was found for the mean of three MVCs (0.81 and 0.78) for the first and second trimesters, respectively. Good reliability of 0.89 was found in the first trimester and a moderate reliability of 0.70 for the second trimester when analyzing the single maximal value of three MVCs.
Good inter-rater reliability was found for the overall sample and first trimester of pregnancy for both mean values and single maximal values of the three MVCs. A good and moderate reliability was respectively found in the second trimester in analyzing the mean and single maximum values of three MVCs.
使用Peritron™会阴肌力计，评估两名评估者对妊娠早期和中期研究参与者三次阴道最大自主收缩（MVC）的平均值和单次最大值的评分者间信度。
36名低风险孕妇。
由两名不同的检查者进行评估，间隔时间为2至7天。统计分析采用一致性相关系数（CCC）和Bland-Altman一致性界限。
对于总体样本，分析三次MVC的平均值时，信度良好，为0.80，单次最大值的信度为（CCC = 0.79）。妊娠早期和中期三次MVC平均值的信度分别为0.81和0.78。分析三次MVC的单次最大值时，妊娠早期信度良好，为0.89，妊娠中期信度中等，为0.70。
对于总体样本和妊娠早期，三次MVC的平均值和单次最大值的评分者间信度良好。在分析妊娠中期三次MVC的平均值和单次最大值时，分别发现了良好和中等的信度。
