ABSTRACT The purpose of this study is to determine the reliability and validity of the translated Korean version of the incontinence-quality of life (I-QOL) in a sample of community-dwelling Korean American women with urinary incontinence in the USA. A survey design was used and a convenience sampling method of 176 Korean American women who reported having urinary incontinence symptoms was used. Translation-back translation procedures were used to translate the English version of the I-QOL into Korean version. Reliability of the Korean I-QOL questionnaire was demonstrated by Cronbach's α coefficients. Pearson's correlations of an item with its own scale and other scales were calculated to evaluate item-convergent and item-discriminant validity. Confirmatory factor analysis was performed to examine the underlying factor structure of the Korean version of the I-QOL. Cronbach's α coefficient for all three subscales was greater than 0·70. The results of item-convergent validity indicated that each item was strongly correlated with the originally belonged subscale. Item-discriminant validity was evidenced by all lower correlations of an item to the other subscales than that of own subscale. Three factors were extracted from I-QOL, accounting for 67·37% of the variance. The findings supported the reliability and validity of Korean version of I-QOL questionnaire. It would be considered as a valuable instrument to assess the different aspects of health-related quality of life in incontinence patients and recommended for use in clinical research.
