^aUnivariate factors with p values < 0.05 were entered into the multiple linear regression

^bThe p-values are bold where they are less than the significance level cut-off of 0.05

^cNominal variables were entered into analyses using dummy coding

^dKnowledge scale was a dichotomous scale of 30 items (range 0–30, high score meaning more correct and better knowledge)

^eAttitude scale used 5-point Likert-type scale for 18 items (range 18–90, high score meaning more positive and better attitude
