Fig. 3.

Moderated mediation model. Note: This model explores whether anger elicited by the selective mandate (vs. voluntary vaccination) policy mediates the relation between policy and the intention to get the second voluntary vaccine—and whether this is only the case when herd immunity has been communicated. The indices in the conceptual diagram (left) and statistical model (right) refer to the effects indicated in Table 2. The results show a significant conditional indirect effect (policy on intention via anger, but only when herd immunity was not communicated).
