Urinary incontinence (UI) in women is a problem of public health with psychological repercussions in various contexts of life. The aim of this study was to adapt and validate the King's Health Questionnaire (KHQ) in women with UI to Portugal.
For the adaptation, a multistep forward-back translation protocol was used. The Positive and Negative Affect Schedule and the Satisfaction with Life Scale were used to validate the KHQ. The evaluation of the psychometric properties involved the assessment of validity, reliability, and test-retest stability in 103 women. A factor analysis was conducted to explore the underlying factor structure of KHQ. Inter-domain correlation was calculated for convergent and discriminant validity assessment.
Exploratory factor analysis identified three factors "personal limitations and daily life", "emotions and social relationships" and "urinary symptoms". Indicators of test-retest stability showed almost perfect agreement with a mean intraclass correlation coefficient (ICC) of 0.937. Internal consistency was found to be high (Cronbach's alfa > 0.7). Furthermore, the Portuguese version of the KHQ significantly correlates with the Positive and Negative Affect Schedule, supporting construct validity.
The Portuguese version of the KHQ was found to be a valid and reliable measure of the quality of life in women with UI in Portugal, being relevant to both clinical practice and research.
女性尿失禁（UI）是一个公共卫生问题，在生活的各个方面都会产生心理影响。本研究的目的是将适用于尿失禁女性的国王健康问卷（KHQ）改编并验证其在葡萄牙的适用性。
在改编过程中，采用了多步骤的前后翻译方案。使用正负性情绪量表和生活满意度量表对KHQ进行验证。对103名女性进行心理测量学特性评估，包括效度、信度和重测稳定性评估。进行因子分析以探索KHQ的潜在因子结构。计算域间相关性以评估收敛效度和区分效度。
探索性因子分析确定了三个因子：“个人限制与日常生活”、“情绪与社会关系”和“泌尿系统症状”。重测稳定性指标显示几乎完全一致，组内相关系数（ICC）均值为0.937。发现内部一致性较高（Cronbach's alfa＞0.7）。此外，葡萄牙语版的KHQ与正负性情绪量表显著相关，支持结构效度。
葡萄牙语版的KHQ被发现是衡量葡萄牙尿失禁女性生活质量的有效且可靠的工具，对临床实践和研究均具有相关性。
