Results: The final questionnaire included knowledge, attitude and practice, with a total of 40 items. The overall Cronbach′s α coefficient of the questionnaire was 0.993. The Cronbach′s α coefficients for the individual dimensions were 0.993, 0.919, and 0.977, respectively, and the test-retest reliability coefficients for the dimensions were 0.943, 0.901, and 0.967, respectively.
