  1. aUnivariate factors with p values < 0.05 were entered into the multiple linear regression
  2. bThe p-values are bold where they are less than the significance level cut-off of 0.05
  3. cNominal variables were entered into analyses using dummy coding
  4. dKnowledge scale was a dichotomous scale of 30 items (range 0–30, high score meaning more correct and better knowledge)
  5. eAttitude scale used 5-point Likert-type scale for 18 items (range 18–90, high score meaning more positive and better attitude
