KTBS, Korean version of the Toileting Behavior Scale; S.E., standard error; AVE, average variance extracted; CR, construct reliability; TB, toileting behavior.

Factor: F1, premature voiding; F2, straining voiding; F3, delayed voiding; F4, place preference for voiding; F5, position preference for voiding.

^a)The original instrument with 18 items.

^b)Seventeen items in which 1 item not meeting the factor loading standard deleted from confirmatory factor analysis.
