  1. Blockwise inclusion of covariates in Model 1, Model 2, and Model 3
  2. Bold denotes significance at p < 0.05
  3. aMean score ‘attitude towards mandates’ consisting of four items (Cronbach’s alpha = 0.88) expressing a negative attitude (score = 1) to a positive attitude (score = 5)
  4. bMean score ‘communication self-efficacy’ consisting of four items (Cronbach’s alpha = 0.87) ranging from very low (score = 1) to very high (score = 5)
  5. c‘Patient clientele’ as portion of patients who are unquestioning acceptors of vaccination ranging from 0 (0%) to 1 (100%)
  6. dExpected consequence of the mandate, item: ‘I expect more children to be vaccinated on time’ (1 = disagree; 5 = strongly agree)
