This study aimed to develop and validate a Decision-Making Ability Scale (DMA-S) for postpartum urinary incontinence (PPUI) women engaging in pelvic floor physical therapy (PFPT).
Items were created in line with a review of the literature and exploratory qualitative study with 22 women. The items were submitted for expert opinion and a pilot implementation was made with 58 women with PPUI. Furthermore, the construct validity of the scale was tested with exploratory factor analysis (EFA) (n = 220) and confirmatory factor analysis (CFA) (n = 240). Internal consistency for the Chronbach's α and test-retest reliability for the intraclass correlation coefficient (ICC) were also investigated for the DMA-S in the study.
The results of the EFA indicated a Kaiser-Meyer-Olkin value of 0.85 and Bartlett's test of sphericity showed a χ value of 8352.101, p < 0.001. After removing one item with factor loading values below 0.50, the resulting factor structure accounted for 83.38% of the total variance. The fit indices of the scale model tested in the CFA were determined as χ /df = 1.08 < 3, root mean square error of approximation = 0.018 < 0.08, comparative fit index = 0.996 > 0.90, Tucker-Lewis index = 0.995 > 0.90, goodness-of-fit index (GFI) = 0.933 > 0.90, adjusted GFI = 0.916 > 0.90, and incremental fit index = 0.996 > 0.90. The Cronbach's α values were 0.95-0.97 for the subdimensions of the scale and 0.93 for the total scale. Data also showed a good test-retest stability (ICC = 0.984).
The DMA-S is a reliable and valid tool for assessing the decision-making ability for PPUI women engaging in PFPT.
本研究旨在为接受盆底物理治疗（PFPT）的产后尿失禁（PPUI）女性开发和验证一种决策能力量表（DMA-S）。
根据文献回顾和 22 名女性的探索性定性研究制定项目。项目提交专家意见，并对 58 名 PPUI 女性进行了初步实施。此外，还通过探索性因子分析（EFA）（n=220）和验证性因子分析（CFA）（n=240）对量表的构念效度进行了测试。还对研究中 DMA-S 的 Cronbach's α 内部一致性和组内相关系数（ICC）的重测信度进行了研究。
EFA 的结果表明，Kaiser-Meyer-Olkin 值为 0.85，Bartlett 的球形检验显示 χ 值为 8352.101，p<0.001。在删除一个因子负荷值低于 0.50 的项目后，得到的因子结构占总方差的 83.38%。在 CFA 中测试的量表模型的拟合指数确定为 χ/df=1.08<3，近似均方根误差=0.018<0.08，比较拟合指数=0.996>0.90，Tucker-Lewis 指数=0.995>0.90，拟合优度指数（GFI）=0.933>0.90，调整拟合优度指数（AGFI）=0.916>0.90，增量拟合指数=0.996>0.90。量表各分量的 Cronbach's α 值为 0.95-0.97，总量表为 0.93。数据还显示出良好的重测稳定性（ICC=0.984）。
DMA-S 是一种可靠有效的工具，可用于评估接受 PFPT 的 PPUI 女性的决策能力。
