Identifying patient-reported outcome measures allows management of urogenital prolapse to be tailored to reflect symptom bother and expectations of treatment. We devised a new single-item questionnaire, the Patient Perception of Prolapse Condition (PPPC), based on the Patient Perception of Bladder Condition (PPBC). The aim was to evaluate the criterion validity, test/re-test reliability and responsiveness of the PPPC. Women attending a tertiary urogynaecology clinic were recruited. At visit 1, patients completed the Prolapse Quality of Life (P-QOL) and PPPC questionnaires, and underwent a Pelvic Organ Prolapse Quantification (POP-Q) examination. This allowed assessment of criterion validity using Spearman's rank correlation (rho) of the PPPC against validated subjective and objective outcomes. At visit 2, within the next 6weeks, PPPC was repeated to assess test/re-test reliability using Cronbach's alpha (α). In those undergoing pelvic floor surgery, responsiveness of the PPPC was assessed at visit 3 by correlating PPPC and P-QOL scores 6weeks post-operatively. A total of 178 patients attended visit 1, 60 attended visit 2 and 58 attended visit 3. At visit 1, there were moderate correlations between the PPPC and both objective (POP-Q: rho = 0.385, p < 0.01, CI 0.192-0.549) and subjective (P-QOL: rho = 0.635, p < 0.01, CI 0.493-0.744) measures confirming criterion validity. Test/re-test reliability was high (α = 0.89). Correlation with post-operative PPPC and P-QOL confirmed moderate responsiveness (rho = 0.54, p < 0.01). The PPPC, a novel single-item patient-reported measure of prolapse condition, demonstrated good criterion validity, test/re-test reliability and responsiveness. These findings support the use of the PPPC as a global assessment of prolapse condition.
