The Cronbach’s α coefficient of the totalquestionnaire was0.822and retest reliability was0.79. Confirmatory factor analysis hasshown that fit good in single factor model of attitudes and practice dimension, but someparts of fitting index didn’t reach the reference value between knowledge dimensionmodel and questionnaire model.
