Abstract

Introduction and hypothesis

We aimed to test validity, reliability and responsiveness of a Dutch version of a prolapse quality-of-life questionnaire (P-QoL).

Methods

P-QoL was translated into Dutch and adjusted by a panel of five experts. The scores of the final version were compared between symptomatic (n = 160) and asymptomatic (n = 80) patients and with findings on vaginal examination (pelvic organ prolapse quantification (POP-Q)). In terms of reliability, Cronbach’s alpha was calculated, and a test–retest (n = 20) was performed. Responsiveness to treatment was assessed by comparing pre- and postoperative scores in 45 patients.

Results

Total scores for each P-QoL domain were different between symptomatic and asymptomatic women (p < 0.001). Severity according to P-QoL correlated well with POP-Q findings. Cronbach’s alphas showed internal consistency within the domains. Test–retest reliability was high. Pre- and postoperative scores for each domain were significantly different (p < 0.001).

Conclusion

The Dutch version of P-QoL is valid, reliable and responsive to assess quality-of-life and symptoms in Dutch-speaking patients with urogenital prolapse.
