A Taiwanese version of the International Consultation on Incontinence Questionnaire--Urinary Incontinence Short Form for pregnant women: instrument validation.

摘要

AIM: To translate the International Consultation on Incontinence Questionnaire--Urinary Incontinence Short Form (ICIQ-UI SF) from English to Taiwanese and to evaluate its reliability and validity for pregnant Taiwanese women. BACKGROUND: Urinary incontinence in pregnant women has been little investigated in Taiwan. A validated assessment instrument for urinary incontinence is needed for pregnant Taiwanese women. DESIGN: A non-experimental design was used to test the psychometric properties of the Taiwanese version of the ICIQ-UI SF. METHOD: The internal consistency reliability and construct validity of the Taiwanese version of the ICIQ-UI SF for pregnant women were evaluated in a random sample of 121 pregnant women at a medical center in Taiwan. Test-retest reliability was assessed for a sample of 55 pregnant women who completed this version at two time points in four weeks. Construct validity was verified with three questions and seven urinary-leakage situations by factor analysis. RESULTS: The Taiwanese version of the ICIQ-UI SF showed adequate test-retest reliability in pregnant Taiwanese women. The Pearson's correlation coefficient of the total score was 0.75, kappa statistics showed excellent or good reproducibility for most items and McNemar's test confirmed that there was no significant difference in the test-retest pair for each item of the scale. The internal consistency reliability of the scale was good, with Cronbach's alpha = 0.80. Three factors were extracted and identified with an eigenvalue >/= 1.04, explaining 65.64% the total variance. The first, second and third factors were 'symptom and quality of life', 'stress incontinence or other types' and 'urge or overflow incontinence'. CONCLUSIONS: The results provide evidence of the validity and reliability of the psychometric properties of the Taiwanese version of the ICIQ-UI SF for pregnant women. RELEVANCE TO CLINICAL PRACTICE: This questionnaire is a suitable instrument for evaluating urinary incontinence in pregnant Taiwanese women.
