Quality of Life in POP: Validity, Reliability and Responsiveness of the Prolapse Quality of Life Questionnaire (P-QoL) in Spanish Women

Abstract

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.

Spanish Questionnaires for the Assessment of Pelvic Floor Dysfunctions in Women: A Systematic Review of the Structural Characteristics and Psychometric Properties

“…After reading the titles and applying the selection criteria to the complete documents, 13 articles and a total of 15 questionnaires were selected [ 8 , 14 , 15 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ].…”

“…These questionnaires assess the symptoms of POP and UI as well as their classification and severity and how they affect women [ 14 , 23 , 24 , 30 , 31 ]: Incontinence Questionnaire-Short Form (ICIQ-SF), Bladder control Self-Assessment Questionnaire (B-SAQ), Prolapse and Incontinence Knowledge Questionnaire (PIKQ), Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ) and Prolapse Quality of Life Questionnaire (P-QoL). Also included is a questionnaire that measures the expectations of self-efficacy and results in women with pelvic floor disorders after performing exercises focused on this [ 27 ]: the Broome Pelvic Muscle Self- Efficacy Scale.…”

“…Four questionnaires have been identified that assess QoL [ 8 , 14 , 26 , 30 ], five of them measure the impact of PFD on sexual function [ 15 , 25 , 28 , 29 , 32 ], seven evaluate the symptoms of POP and UI [ 8 , 14 , 25 , 26 , 27 , 30 , 31 ], and one was focused on pregnant women [ 26 ].…”

“…To evaluate the QoL of people suffering from PFD, four questionnaires were found [ 8 , 14 , 26 , 30 ], as already mentioned above. These questionnaires, despite evaluating the QoL, do not contemplate the area of sexual function and do not contain questions that deal with it; therefore, it is necessary to have other tools that do take it into account.…”

“…For example, the EPIQ [ 14 ] contains 53 items and each item has a range from 0 to 10. The P-QoL [ 30 ] contains 20 items and the scale ranges from 0 to 100, the IIQ-7 [ 26 ] contains 7 items and the scale ranges from 0 to 3, and finally, the PFDI-20 [ 8 ] contains 20 items distributed in 3 blocks with a maximum score of 300.…”
