The Prolapse and Incontinence Knowledge Quiz (PIKQ) was developed to assess women's knowledge of pelvic organ prolapse (POP) and urinary incontinence (UI).
To perform the translation, cross-cultural adaptation, and measurement properties of the PIKQ for Brazilian women with UI (PIKQ-Br).
The measurement properties were tested for validity (content and face, structural, and hypotheses testing) and reliability (internal consistency, test-retest, and measurement error) in 130 women with UI from Recife, Brazil. Hypotheses testing for construct validity was assessed by Spearman's correlation coefficients. The standard error of measurement and the smallest detectable change were used to determine the measurement error. The structural validity was examined using a confirmatory factor analysis. Test-retest reliability and internal consistency were determined using the intraclass correlation coefficient (ICC) and Cronbach's alpha.
The structural validity was analyzed with a single factor and 12 questions, revealing the goodness-of-fit was inappropriate (TLI=0.60; RMSEA=0.07). The two factors and 10-question version presented adequate values and factor loading (>0.30), except questions 1, 7, and 8 in PIKQ-POP. Positive and moderate correlations for hypotheses testing were observed for PIKQ-UI-10 (rho=0.439). Positive and weak correlations were observed for PIKQ-POP-10 (rho=0.278). Cronbach's alpha coefficients for PIKQ-UI-10 were 0.718 and 0.710 for PIKQ-POP-10. Both scales showed excellent reliability (ICC>0.93). The PIKQ-UI-10 and PIKQ-POP-10 had SEM values of 0.24 and 0.31 and SDC of 0.66 and 0.85, respectively.
The PIKQ-Br with 10 questions and two-factor presented adequate measurement properties, and can be a useful instrument to assess women's knowledge about UI and POP.
脱垂与尿失禁知识测验（PIKQ）旨在评估女性对盆腔器官脱垂（POP）和尿失禁（UI）的了解程度。
对巴西尿失禁女性的PIKQ（PIKQ-Br）进行翻译、跨文化调适及测量特性研究。
对来自巴西累西腓的130名尿失禁女性进行测量特性测试，包括效度（内容和表面效度、结构效度以及假设检验）和信度（内部一致性、重测信度和测量误差）。通过斯皮尔曼相关系数评估结构效度的假设检验。使用测量标准误和最小可检测变化来确定测量误差。采用验证性因子分析检验结构效度。使用组内相关系数（ICC）和克朗巴哈α系数确定重测信度和内部一致性。
单因素12题版本的结构效度分析显示拟合优度不佳（TLI = 0.60；RMSEA = 0.07）。两因素10题版本呈现出合适的值和因子载荷（>0.30），除了PIKQ-POP中的第1、7和8题。PIKQ-UI-10在假设检验中观察到正相关且中等相关（rho = 0.439）。PIKQ-POP-10观察到正相关且弱相关（rho = 0.278）。PIKQ-UI-10的克朗巴哈α系数为0.718，PIKQ-POP-10为0.710。两个量表均显示出极好的信度（ICC>0.93）。PIKQ-UI-10和PIKQ-POP-10的测量标准误值分别为0.24和0.31，最小可检测变化分别为0.66和0.85。
包含10个问题的两因素PIKQ-Br具有合适的测量特性，可作为评估女性对尿失禁和盆腔器官脱垂知识的有用工具。
