RESUMEN
OBJECTIVE: Despite high prevalence and burden of pelvic floor dysfunctions (PFD), there is a limited number of scales assessing knowledge of pelvic floor health (PFH), and no studies comparing their psychometric or feasibility properties. The study aimed both to investigate the psychometric properties and feasibility of Incontinence Quiz (IQ), Prolapse and Incontinence Knowledge Questionnaire (PIKQ) and Pelvic Floor Health Knowledge Questionnaire (PFHKQ), and to compare level of PFH knowledge in women with and without PFD. STUDY DESIGN: In this prospective cross-sectional study, a total of 150 women were included. After recording physical-sociodemographic characteristics, obstetric histories and menstrual status, Pelvic Floor Distress Inventory-20 and Female Sexual Function Index were administered to classify them into study groups as women with and without PFD. Their PFH knowledge was assessed using IQ, PIKQ and PFHKQ, which were filled twice with one week interval for the test-retest purpose. The scores, reliability, validity, ceiling-floor effects and feasibility of the knowledge scales were compared with each other, and between the study groups. RESULTS: IQ, PIKQ, and PFHKQ scores of women with and without PFD were similar. Based on response patterns to items, PFHKQ had the highest internal consistency followed by PIKQ and IQ. The PIKQ was the most stable scale across the total sample and in the PFD group. The PFHKQ had the highest ICC value in women without PFD. There was a strong correlation between the total scores of knowledge scales in both groups. Scores of knowledge and symptom scales were not significantly correlated. IQ was completed in the shortest time, and was easier to complete than PFHKQ. Only the diagnosis/treatment subscale of PFHKQ had a ceiling effect. CONCLUSION: It was concluded that PFH knowledge of women with and without PFD were at a low-moderate level and similar to each other; IQ, PIKQ and PFHKQ were reliable, valid and feasible scales, which can be used in measuring knowledge level about PFH.
