Abstract

Pelvic floor disorders (PFDs) impact women worldwide and are assessed using instruments such as the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7). There are no known valid PFD instruments in Uganda. This study's purpose was to translate and test the reliability and validity of the PFDI-20 and PFIQ-7 in Luganda. It was predicted that these instruments would be reliable and valid to assess the presence and impact of PFD in parous Luganda-speaking women.INTRODUCTION AND HYPOTHESISPelvic floor disorders (PFDs) impact women worldwide and are assessed using instruments such as the Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7). There are no known valid PFD instruments in Uganda. This study's purpose was to translate and test the reliability and validity of the PFDI-20 and PFIQ-7 in Luganda. It was predicted that these instruments would be reliable and valid to assess the presence and impact of PFD in parous Luganda-speaking women.The translated PFDI-20 and PFIQ-7 were administered to parous Luganda-speaking women and readministered 4-8 months after. The Pelvic Organ Prolapse Quantification (POP-Q) examination determined the presence of pelvic organ prolapse (POP) and a cough-stress test (CST) measured urinary leakage. Analysis was completed using Cronbach's α co-efficient for internal consistency and Spearman's correlation coefficients and Wilcoxon rank sum tests for construct validity.METHODSThe translated PFDI-20 and PFIQ-7 were administered to parous Luganda-speaking women and readministered 4-8 months after. The Pelvic Organ Prolapse Quantification (POP-Q) examination determined the presence of pelvic organ prolapse (POP) and a cough-stress test (CST) measured urinary leakage. Analysis was completed using Cronbach's α co-efficient for internal consistency and Spearman's correlation coefficients and Wilcoxon rank sum tests for construct validity.Of the 159 participants, 93 (58.3%) had stage II POP or higher. The PFDI-20 and PFIQ-7 demonstrated minimal bother and impact on activities of daily living respectively. The Urinary Distress Inventory 6 (UDI-6) scores on the PFDI-20 showed a strong positive association with the presence of urinary incontinence. When PFD was defined by responses to symptom assessment, the translated PFDI-20 and PFIQ-7 could differentiate between individuals with and without PFD.RESULTSOf the 159 participants, 93 (58.3%) had stage II POP or higher.

When PFD was defined by responses to symptom assessment, the translated PFDI-20 and PFIQ-7 could differentiate between individuals with and without PFD.The UDI-6 section of the PFDI-20 was found to be valid in Luganda. The PFIQ-7 and the entirety of the PFDI-20 were not found to be reliable or valid, likely because of the low prevalence of PFDs in the study population.CONCLUSIONSThe UDI-6 section of the PFDI-20 was found to be valid in Luganda. The PFIQ-7 and the entirety of the PFDI-20 were not found to be reliable or valid, likely because of the low prevalence of PFDs in the study population.
