Abstract: This study examined the order effects of humor and risk messaging strategies in public service announcements promoting COVID-19 vaccination on persuasion outcomes, with psychological reactance and perceived effectiveness as serial mediators, and trust in science as a moderator. Findings showed that a humor-then-risk (risk-then-humor) structure predicted lower reactance for participants with low (high) trust in science. Moreover, for low-trust participants, a humor-then-risk order yielded higher vaccination intention via reduced reactance and increased perceived PSA effectiveness.
