The aim of this study was to measure the reliability, internal consistency, and construct validity of the Kidney Symptom Questionnaire for the Brazilian population.
This is a cross-cultural adaptation and questionnaire validation study. We included native Brazilians of both sex aged>18 years, as well as hypertensive and/or diabetic patients. All participants were assessed using Screening for Occult Renal Disease, EuroQol 5 Dimensions, 36-Item Short Form Survey, and the Kidney Symptom Questionnaire. We used Spearman's coefficient (rho) to measure the correlations between the Kidney Symptom Questionnaire and other instruments; Cronbach's alpha to measure internal consistency; and intraclass correlation coefficient, standard error of measurement, and minimum detectable change to measure test-retest reliability.
The sample was formed by 121 adult participants, mostly female, with systemic arterial hypertension and/or diabetes mellitus. We found excellent reliability (intraclass correlation coefficient≥0.978), adequate internal consistency (Cronbach's alpha≥0.860), and adequate construct validity on the Kidney Symptom Questionnaire domains; besides, we observed significant correlations between the Kidney Symptom Questionnaire and other instruments.
The Brazilian version of the Kidney Symptom Questionnaire has adequate measurement properties to assess chronic/occult kidney disease in patients who do not require renal replacement therapy.
本研究旨在测量巴西人群的 Kidney Symptom Questionnaire 的可靠性、内部一致性和结构效度。
这是一项跨文化适应性和问卷验证研究。我们纳入了年龄>18 岁的母语为巴西的成年人，以及高血压和/或糖尿病患者。所有参与者均接受了 Screening for Occult Renal Disease、EuroQol 5 Dimensions、36-Item Short Form Survey 和 Kidney Symptom Questionnaire 的评估。我们使用 Spearman 相关系数（rho）来衡量 Kidney Symptom Questionnaire 与其他工具之间的相关性；使用 Cronbach's alpha 来衡量内部一致性；使用组内相关系数、测量标准误差和最小可检测变化来衡量测试-重测信度。
样本由 121 名成年参与者组成，大多数为女性，患有系统性动脉高血压和/或糖尿病。我们发现 Kidney Symptom Questionnaire 的信度极好（组内相关系数≥0.978），内部一致性适度（Cronbach's alpha≥0.860），各领域的结构效度适度；此外，我们观察到 Kidney Symptom Questionnaire 与其他工具之间存在显著相关性。
巴西版 Kidney Symptom Questionnaire 具有足够的测量特性，可用于评估不需要肾脏替代治疗的慢性/隐匿性肾病患者。
