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 χ2 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 χ2 /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.
