Scale consisted of 15 items. Items were answered on a scale from 1 (strongly disagree) to 7 (strongly agree). Cronbach’s alpha for scale: T0 α=0.72 and T1 α=0.74.
T0: baseline survey; T1: follow-up survey.
Frequent user: places a catheter a few times a month or more often; infrequent user: places a catheter a few times a year or less often.
