Methods Based on KAP theory and CAUTI preventive current guideline, the scale was developed by using literature review, Delphi expert inquiry. A questionnaire survey was conducted among 300 medical workers in a third grade A hospital in Qingdao. Exploratory factor analysis and confirmatory factor analysis were both conducted to screen the items further. The psychometric properties of scale was tested. Results The finalized scale included 4 subscales and 45 items, amount to 63.21% of the variance contribution rate. The total Cronbach's alpha was 0.914, and the split half reliability was 0.812. The content validity of the scale was 0.895, while it ranged from 0.846-1.000 for each subscale. The correlation of item-to total was 0.711-0.862, and the correlation coefficient of item-to-item ranged from 0.425-0.564. Conclusions The scale of CAUTI KAP has good reliability and validity.
