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.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.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.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.
