The item content validity (I-CVI) and questionnaire content validity (S-CVI) were 0.889 ~ 1.000 and 0.974, respectively. Exploratory factor analysis extracts three common factors (dimensions), the cumulative variance contribution rate is 65.656%, the Cronbach'α coefficient of the total questionnaire is 0.843, and the Cronbach's α coefficients of the three dimensions of KAP are 0.754, 0.887 and 0.940, respectively. The split-half reliability is 0.816. The test-retest reliability of the total questionnaire is 0.813.
