Validation of the Korean language version of the incontinence‐quality of life scale

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�...
