Abstract
Objectives: To develop a Thai version of the pelvic floor bother questionnaire (PFBQ) and to evaluate its reliability and validity. The correlation with the pelvic floor distress inventory-20 (PFDI-20) questionnaire was evaluated.
Materials and Methods: A Thai version of PFBQ was developed from the original English version by translation and back translation method. The psychometric properties of the questionnaire were evaluated in 100 Thai women with pelvic floor dysfunction (PFD). Internal consistency was measured by Cronbach’s alpha coefficient for all items. Test-retest reliability was measured by intraclass correlation coefficient (ICCr). The agreement of each item between two visits (two-week interval) was measured by Kappa coefficient. Concurrent validity of the PFBQ was evaluated by assessing its correlation with the PFDI-20 using the Spearman’s correlation coefficient (r).
Results: A total of 100 women who had PFD symptoms (mean age ± standard deviation = 61.89 ± 11.70 years) were enrolled in the study. All women completed the study. The Thai version of PFBQ demonstrated acceptable internal consistency (Cronbach’s alpha = 0.76) and excellent test-retest reliability (ICCr = 0.90, 95% confidence interval 0.85-0.93). The agreement of each question between two visits ranged from moderate to substantial (Kappa = 0.43-0.69). There was a positive correlation between the Thai version of PFBQ and the PFDI-20 (r = 0.81).
Conclusion: The Thai version of the PFBQ is valid and reliable. It may be used as a tool to identify the presence of symptoms and assess the severity of bother of various pelvic floor dysfunction in Thai women. PFBQ can be used as a patient reported outcome instrument in both research and clinical practice.
