Chinese validation of Urogenital Distress Inventory and Incontinence Impact Questionnaire short form.
OBJECTIVE
UDI-6 and IIQ-7 are useful disease-specific questionnaires evaluating the impact of urinary incontinence on the QOL of women. We aim at validating them in Chinese language.


METHODS
Both instruments were translated; 207 urinary incontinent women completed UDI-6 and IIQ-7, SF-36, bladder diary and urodynamic evaluation. The reliability and validity were assessed.


RESULTS
There were high internal consistency (Cronbach's alpha for UDI-6 and IIQ-7 was 0.80 and 0.93) and test-retest reliability (Intraclass correlation coefficient was 0.72 and 0.75, P < 0.001). Scoring of UDI-6 and IIQ-7 was negatively correlated with SF-36 (P < 0.001); positively correlated with daytime urinary frequency and incontinent episodes (P < 0.001), and women's VAS (P < 0.001). Subscales of UDI-6 and IIQ-7 could discriminate women with different urodynamic diagnoses.


CONCLUSIONS
The Chinese UDI-6 and IIQ-7 is reliable and valid. Study on the responsiveness to treatment is in progress. They are useful in assessing impact of the urinary incontinence in Chinese women.
