Abstract

Introduction and hypothesis: Our objective was to translate and validate a Portuguese version of the Urinary Incontinence-Specific Quality-of-Life Instrument (I-QOL), a questionnaire that is widely used in clinical trials.

Methods: Fifty patients completed the same questionnaire twice at a 2-week interval. During the first visit, we conducted a face-to-face interview and collected demographic data. The King's Health Questionnaire was completed during the same visit for comparisons.

Results: The results showed that the Portuguese version of the I-QOL has very good psychometrics properties. Reliability was assessed by Cronbach's alpha (0.93), reproducibility was calculated through the intraclass correlation coefficient (0.88), construct validity was determined by comparing the I-QOL scores and King's Health scores, and discriminant validity was calculated by comparing the total I-QOL scores with measures of gravity.

Conclusions: We conclude that the Portuguese version of the I-QOL is a very good tool for the evaluation quality-of-life in women with urinary incontinence in Portuguese-speaking countries.

葡萄牙验证尿失禁特定生活质量仪器:I-QOL。

前言和假设:我们的目的是翻译和验证葡萄牙语版本的尿失禁特异性生活质量量表(I-QOL)，这是一份广泛用于临床试验的问卷。方法:50例患者每隔2周完成两次相同的问卷调查。在第一次访问中，我们进行了面对面的访谈并收集了人口统计数据。在同一次访问期间完成了国王健康问卷，以进行比较。结果:葡萄牙语版的I-QOL具有很好的心理测量学性质。通过Cronbach’s alpha(0.93)评估信度，通过类内相关系数(0.88)计算再现性，通过比较I-QOL评分和King’s Health评分来确定结构效度，通过比较I-QOL总分和重力测量来计算判别效度。结论:葡萄牙语版I-QOL是评估葡语国家女性尿失禁患者生活质量的一个很好的工具。
