The Prolapse Quality of Life Questionnaire (P-QoL) is a specific questionnaire created to assess the impact of pelvic organ prolapse on women's quality of life. The aim of the present study was to cross-culturally adapt and assess the psychometric properties of the P-QoL for Spanish women. The cross-cultural adaptation was conducted by a standardized translation/back-translation method. Psychometric analysis was performed by assessing the validity, reliability, responsiveness and feasibility. A total of 200 Spanish women were recruited and assigned to symptomatic and asymptomatic groups. The Spanish P-QoL version demonstrated good content validity. Convergent validity showed high intercorrelations with the Pelvic Floor Distress Inventory short form and the Pelvic Floor Impact Questionnaire short form. The discriminant validity showed statistically significant differences between the symptomatic and the asymptomatic groups. The internal consistency was high and of acceptable values. The test-retest reliability was shown to be high in all the cases. Regarding responsiveness, the effect size and standardized response mean demonstrated moderate values. The average time for administration was 10 (3) min. The Spanish P-QoL showed considerable support for the appropriate metric properties of validity, reliability, responsiveness and feasibility to evaluate the symptom severity and its impact on the quality of life in Spanish women with urogenital prolapse.
