Validation of the Prolapse Quality-of-Life Questionnaire (P-QoL) in Portuguese version in Brazilian women.

Abstract

Introduction and hypothesis: The aim of this study is to validate the Portuguese translated version of the Prolapse Quality-of-Life Questionnaire (P-QoL).

Methods: Ninety-eight women completed the P-QoL questionnaire translated into Portuguese at baseline and on the second visit, 2 weeks later. Clinical data and Pelvic Organ Prolapse Quantification Index (POP-Q) according to the International Continence Society were obtained. Psychometric properties of the questionnaire were assessed.

Results: Sixty-eight symptomatic and 30 asymptomatic women for POP symptoms were studied. Most patients presented POP-Q > 2. The P-QoL demonstrated good psychometric properties. The test-retest reliability confirmed a highly significant stability between the total scores for each domain (P < 0.0001). The construct validation distinguished differences in P-QoL questionnaire scores between symptomatic and asymptomatic women.

Conclusion: The Portuguese version of the P-QoL questionnaire is a valid and reliable instrument to assess quality of life in Brazilian women with pelvic organ prolapse.
