Urinary incontinence (UI) is a common disorder in women that can affect a person's quality of life. There are several instruments to assess the severity of urinary incontinence. One of the common tools is the Protection, Amount, Frequency, Adjustment, Body image (PRAFAB) questionnaire. Therefore, this study was performed with the aim of assessing the validity and reliability of the Persian version of the PRAFAB questionnaire.
First, the English version of the questionnaire was translated into Persian. Second, the psychometric properties of the Persian version were collected in 60 women with urinary incontinence referred to Al-Zahra Hospital by an expert team. Content validity (CV) was evaluated through CV index (CVI) and CV ratio (CVR). Construct validity was evaluated using exploratory factor analysis and reproducibility was tested based on test-retest reliability using intraclass correlation coefficient (ICC). Internal consistency was calculated using Cronbach's α.
The results showed acceptable CVI in relevancy, clarity, and simplicity, acceptable CVR for all items, good internal consistency (Cronbach's alpha = 0.738) and excellent repeatability (ICC = 0.98).
The Persian version of the PRAFAB questionnaire has acceptable validity and reliability and in future it can be used as a suitable evaluation instrument to assess urinary incontinence in Iranian women.
尿失禁（UI）是一种常见的女性疾病，会影响一个人的生活质量。有几种仪器可以评估尿失禁的严重程度。其中一种常见的工具是保护、量、频率、调整、身体形象（PRAFAB）问卷。因此，本研究旨在评估 PRAFAB 问卷的波斯语版本的有效性和可靠性。
首先，将问卷的英文版本翻译成波斯语。其次，由一个专家团队对 60 名患有尿失禁的女性进行了问卷调查，以收集波斯语版本的心理测量特性。内容效度（CV）通过 CV 指数（CVI）和 CV 比值（CVR）进行评估。结构效度采用探索性因子分析进行评估，重复性根据重测信度用组内相关系数（ICC）进行测试。内部一致性采用 Cronbach's α 进行计算。
结果表明，相关性、清晰度和简单性方面的 CVI 可接受，所有项目的 CVR 可接受，内部一致性良好（Cronbach's α = 0.738），可重复性极好（ICC = 0.98）。
PRAFAB 问卷的波斯语版本具有可接受的有效性和可靠性，将来可以作为评估伊朗女性尿失禁的合适评估工具。
