Validation and translation of the Hungarian version of the Australian Pelvic Floor Questionnaire (APFQ-H)

Introduction and hypothesis The aims of the study were the translation, cultural adaptation, and validation of self-administered Australian Pelvic Floor Questionnaire (APFQ) on a Hungarian population. Methods The validation was performed in 294 women over 18 who agreed to answer the Hungarian version of the APFQ. The validation of the questionnaire included evaluation of content/face validity, internal consistency, construct validity, test-retest reproducibility, discriminant validity and convergent validity. Results Acceptable and good internal consistency was observed in all four dimensions [McDonald's omega (95% confidence interval) coefficients were > 0.7 for each dimension: bladder 0.888, bowel 0.790, prolapse 0.895 and sexual function 0.738]. Test-retest analyses revealed high reproducibility with intraclass correlation coefficients (bladder 0.83, bowel 0.92, prolapse 0.96 and sexual function 0.87). Prolapse symptom score correlated significantly with Pelvic Organ Prolapse Quantification (POP-Q), and bladder score correlated significantly with the results of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ UI SF) (convergent validity). Scores distinguished between patients with pelvic floor disorders and controls (high discriminant validity). Conclusions Hungarian version of the self-administered APFQ is a reliable and valid instrument for evaluating symptom severity and impact of pelvic floor dysfunction on the quality of life of Hungarian women.

Automated summary

The Hungarian version of the self-administered Australian Pelvic Floor Questionnaire (APFQ) has been translated, culturally adapted and validated in this study. The results indicate that the Hungarian version of APFQ is a reliable and valid instrument for evaluating symptom severity and impact of pelvic floor dysfunction on the quality of life of Hungarian women.
