Abstract
Objectives: The King’s Health Questionnaire (KHQ) and the International Consultation on Incontinence Modular Questionnaire (ICIQ-SF) Short Form are widely used in clinical practice. The aim of this study was to assess the reliability of KHQ and ICIQ-SF in Polish women.
Material and methods: One hundred fifty-five women with urinary incontinence (UI) aged between 19–82 years underwent urodynamic investigation and completed both KHQ and ICIQ-SF. We performed Principal Component Analysis (PCA) using VARIMAX rotation for all questionnaire pieces to estimate the factor structure and construct the validity of the KHQ and ICIQ. PCA results were also confirmed by Spearman’s correlations between KHQ and ICIQ items. Moreover, by Cronbach’s alpha coefficient (α) we assessed the internal consistency of the KHQ and ICIQ. STATISTICA version 13.1 software (StatSoft, Poland), and open-source R software (version 3.4.4) were used for statistical analysis.
Results: Of the study group, 77 (49.6 %) patients had stress urinary incontinence (SUI), 9 (5.8%) patients had Urgency, 10 (6.45%) had OAB and 21 (13.5 %) had MUI. The factor analysis of the KHQ questions showed four main components, and ICIQ-SF- two main components. Correlations between KHQ and ICIQ-SF were from weak (0.1–0.3) to high (0.5–0.7). The KHQ’s Cronbach’s alpha was 0.93 and the ICIQ- 0.7. The results obtained from the questionnaire forms did not differ among study groups.
Conclusions: The Polish versions of the KHQ and ICIQ-SF questionnaires have good psychometric values and are useful diagnostic tools in the population of urinary incontinent women.
