INTRODUCTION AND HYPOTHESIS
The aim of this study was to translate and validate a Brazilian version of the "Prolapse Quality of Life Questionnaire" (P-QOL) an instrument to assess quality of life of women with genital prolapse.
METHODS
Sixty-five patients answered the P-QOL twice. The reliability was assessed using Cronbach's alpha coefficient and validity was assessed comparing symptom scores between affected and asymptomatic women and comparing symptom scores with prolapse stages. Responsiveness was obtained with patients who underwent to genital prolapse surgical corrections.
RESULTS
The results have showed that the Brazilian Portuguese version of P-QOL has had very good psychometric properties. All items achieved a Cronbach's alpha greater than 0.70. The test-retest reliability confirmed that the questionnaire was able to detect changes in quality-of-life after treatment.
CONCLUSIONS
We concluded that the Portuguese version of the P-QOL is a very good instrument to assess quality-of-life in women with genital Prolapse.
引言与假设
本研究旨在翻译并验证巴西版的“盆腔器官脱垂生活质量问卷”（P-QOL），这是一种用于评估生殖器脱垂女性生活质量的工具。
方法
65名患者两次回答P-QOL问卷。使用克朗巴哈α系数评估信度，通过比较患病人群与无症状女性的症状评分以及症状评分与脱垂阶段来评估效度。对接受生殖器脱垂手术矫正的患者进行反应度分析。
结果
结果表明，巴西葡萄牙语版的P-QOL具有非常良好的心理测量特性。所有项目的克朗巴哈α系数均大于0.70。重测信度证实该问卷能够检测治疗后生活质量的变化。
结论
我们得出结论，葡萄牙语版的P-QOL是评估生殖器脱垂女性生活质量的一种非常好的工具。
