Reliability of The King's Health Questionnaire and the International Consultation on Incontinence Modular Questionnaire (ICIQ-SF) Short Form in assessing urinary incontinence effects in Polish women.

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.

Principal component analysis and internal reliability of the Polish version of MESA and UDI-6 questionnaires.

OBJECTIVES: Urinary incontinence (UI) can affect up to 50% of the population of women over the age of 50. In order to objectively assess discomfort in women with UI prior to initiating treatment and monitoring the outcomes of the treatment, validated questionnaires need to be used to examine the impact of UI on health-related quality of life (HR-QoL). The Urogenital Distress Inventory - Short Form (UDI-6) and the Medical Epidemiologic and Social Aspects of Ageing (MESA) questionnaires are used typically. Assessment of the Polish translation of the MESA and UDI-6 questionnaires. MATERIAL AND METHODS: 155 patients with symptoms of UI were enrolled. Each of the patients completed the MESA and UDI questionnaires prior to being examined. The final diagnosis was made after diagnostic tests were carried out in the patients. RESULTS: Principle component analysis showed division of the Polish versions of the questionnaires into domains identical to the original version. Analyses of internal consistency reliability revealed high internal consistency for the MESA questionnaire (0.90) and a low reliability of the UDI-6 questionnaire (0.44). CONCLUSIONS: The Polish version of the MESA questionnaire was demonstrated to be a clinically useful diagnostic tool in the studied population, UDI-6 did not reached a sufficiently high reliability in the study group to be recommended as a diagnostic tool.

THE AIM: The assessment of the usefulness of the following questionnaires: UDI 6SF, King's Health Questionnaire, Gaudenz, MESA, ICIQ-SF in diagnosis of different types of women's urinary incontinence. MATERIAL AND METHODS: The study included 100 women who were hospitalized in the Department of Urology of St. Rafael Hospital in Czerwona Góra due to urinary incontinence. On the basis of the received data we have compared the data from questionnairies to the results of the urodynamic study. RESULTS: The mean age of women was 55.6 years. The stress urinary incontinence (SUI) was diagnosed in 32%, urgent urinary incontinence (UUI) in 10% and mixed urinary incontinence (MUI) in 55% of women, and neurogenic bladder in 3%. The data obtained from the study showed that questionnaires had 98% sensitivity and 50% specificity in diagnosing the type of urinary incontinence in women. CONCLUSIONS: 1. Data obtained from the questionnaires fails to offer enough information to make a certain diagnosis of urinary incontinence. 2. The questionnaires: ICIQ-SF, Gaudenz and MESA are effective in the diagnosis of mixed urinary incontinence. 3. In spite of their high sensitivity, the specificity of questionnaires in the diagnosis of urinary incontinence is rather low.
