Electronic pelvic floor symptoms assessment: tests of data quality of ePAQ-PF.

Full Abstract

The objective of the study was to test the data quality, scaling assumptions and scoring algorithms underlying the electronic personal assessment questionnaire-pelvic floor (ePAQ-PF). A cross-sectional survey of 599 women with pelvic floor disorders was carried out. Tests of data quality included secondary factor analysis, internal reliability, descriptive statistics, levels of missing data, floor and ceiling effects, item-to-total correlation scores, item discriminant and convergent validity. Secondary factor analysis verified the domain structure of ePAQ-PF. All 19 domains were internally reliable with Cronbach's alpha scores ranging from 0.71 to 0.93. Missing response rates ranged from 0.2% to 1.3%, and all items were found to be most highly correlated with their own corrected scale. Results confirmed the factor structure, data quality and scoring and scaling assumptions of ePAQ-PF, thereby verifying its suitability for measuring symptoms, bother and quality of life in women with pelvic floor disorders.
