To validate the Italian version of two questionnaires for lower urinary tract symptoms (LUTS), i.e. the long (LF) and the short form (SF) of the International Consultation on Incontinence Questionnaire (ICIQ).
Two native Italian speakers and a native English speaker collaborated with clinical investigators through a multistep process to obtain a consensus version of the questionnaires. The resulting Italian versions were then pre-tested during a pilot study on 16 women for the LF and 10 for the SF. The final versions of the ICIQ-LF and ICIQ-SF were administered to two samples of consecutive female patients, aged > or = 18 years, who had been having LUTS for > or = 3 months, with respectively 82 and 50 women. Internal consistency and test-retest reliability were then assessed; to evaluate the latter, a subset of patients (25 for the ICIQ-LF and 42 for ICIQ-SF) was re-rated. To test the capacity of the questionnaires to discriminate women with or without LUTS (respectively cases and controls), a sample of healthy women was also enrolled and assessed.
Both scales showed good psychometric properties overall. The correlation coefficient between ratings was > 0.75 in both questionnaires, and the discriminant power between cases and controls was confirmed for both scales. The ICIQ-SF showed good internal consistency for the total score (Cronbach's alpha 0.90). The sections of the ICIQ-LF 'impact of incontinence on everyday life', 'emotional aspects', 'urinary symptoms' and the degree of bother seemed to be internally consistent (Cronbach's alpha > 0.70); there was a weak relationship for items related to 'sexual matters' (Cronbach's alpha 0.38).
The Italian version of both questionnaires is a valid and robust instrument which can now be used reliably both in daily practice and in clinical research.
验证两份用于评估下尿路症状（LUTS）的问卷的意大利语版本，即国际尿失禁咨询委员会问卷（ICIQ）的长版（LF）和短版（SF）。
两名意大利语母语者和一名英语母语者通过多步骤流程与临床研究人员合作，以获得问卷的共识版本。随后，在一项试点研究中，对16名女性进行LF预测试，对10名女性进行SF预测试。将ICIQ-LF和ICIQ-SF的最终版本分别施用于两个连续的女性患者样本，这些患者年龄≥18岁，患有LUTS≥3个月，分别有82名和50名女性。然后评估内部一致性和重测信度；为评估后者，对一部分患者（ICIQ-LF为25名，ICIQ-SF为42名）进行重新评分。为测试问卷区分有或无LUTS女性（分别为病例组和对照组）的能力，还纳入并评估了一组健康女性样本。
两个量表总体上均显示出良好的心理测量特性。两份问卷中评分之间的相关系数均>0.75，且两个量表区分病例组和对照组的能力均得到证实。ICIQ-SF总分的内部一致性良好（Cronbach's α为0.90）。ICIQ-LF中“尿失禁对日常生活的影响”“情感方面”“泌尿系统症状”和困扰程度部分似乎具有内部一致性（Cronbach's α>0.70）；与“性方面”相关的项目相关性较弱（Cronbach's α为0.38）。
两份问卷的意大利语版本都是有效且可靠的工具，现在可在日常实践和临床研究中可靠使用。
