Purpose: To evaluate the psychometric properties of the Korean version of the Incontinence-Quality of Life (I-QOL) instrument in Korean women with symptoms of stress urinary incontinence.
Material and Methods: Prospective study involving women with stress urinary incontince, who eventually underwent anti-incontinence surgery (n=89) was undertaken. Convergent and discriminant validity were assessed. Reliability was assessed by calculating Cronbach¡¯s alpha coefficient, and stability was assessed as well. Sensitivity to clinical change before and after operation was also evaluated.
Results: The Korean version of I-QOL proved to be not difficult to understand and acceptable to the patients. Significant association was found between the I-QoL scores and clinical parameters including overall symptom severity. The domain score were significantly different between control group and patient groups. Convergent validity of the I-QOL also proved adequate. Cronbach¡¯s alpha coefficients (>0.78) indicated reasonable internal consistency. Results from test-retest showed reproducible. I-QOL domains were generally responsive to clinical efficacy variables; the I-QOL also showed statistically significant sensitivity to changes in patients¡¯ perceptions of bladder condition in all domains.
Conclusion: The Korean version of the I-QOL is valid and reliable for clinical use in Korean patients with stress urinary incontinence.
