父母中的反疫苗阴谋论信念可能会降低疫苗接种意愿。父母对反疫苗阴谋论的信念也与他们对其他父母阴谋论的看法有关。此外，研究表明，父母对反疫苗阴谋论信念规范存在误解：英国父母高估了其他父母的反疫苗阴谋论信念。本研究测试了社会规范方法干预措施的有效性，该方法利用规范反馈纠正误解，以减少英国父母的反疫苗阴谋信念并增加疫苗接种意愿。在基线时，202 名英国幼儿父母报告了他们对反疫苗阴谋论的个人信仰、未来接种疫苗的意图以及他们对其他英国父母的信仰和意图的看法。然后，参与者被随机分配到规范反馈条件（n = 89）或仅评估控制条件（n = 113）。规范反馈将参与者的个人反疫苗阴谋信念以及对其他英国父母信念的看法与实际规范信念水平进行了比较。接受规范性反馈的父母在测试后立即表现出个人对反疫苗阴谋论的信念显着降低。正如假设的那样，反疫苗阴谋论信念的规范观念的变化介导了干预的效果。干预并没有直接增加疫苗接种意愿，但中介分析表明，规范反馈增加了对其他父母疫苗接种意愿的看法，进而增加了个人疫苗接种意愿。六周的随访后没有留下明显的效果。目前的研究表明，社会规范方法干预措施对于纠正英国家长的误解和减少反疫苗阴谋论的潜在效用。进一步的研究可以探索利用补充干预来维持疗效。
Anti-vaccine conspiracy beliefs among parents can reduce vaccination intentions. Parents’ beliefs in anti-vaccine conspiracy theories are also related to their perceptions of other parents’ conspiracy beliefs. Further, research has shown that parents hold misperceptions of anti-vaccine conspiracy belief norms: UK parents over-estimate the anti-vaccine conspiracy beliefs of other parents. The present study tested the effectiveness of a Social Norms Approach intervention, which corrects misperceptions using normative feedback, to reduce UK parents’ anti-vaccine conspiracy beliefs and increase vaccination intentions. At baseline, 202 UK parents of young children reported their personal belief in anti-vaccine conspiracy theories, future intentions to vaccinate, and their perceptions of other UK parents’ beliefs and intentions. Participants were then randomly assigned to a normative feedback condition (n = 89) or an assessment-only control condition (n = 113). The normative feedback compared participants’ personal anti-vaccine conspiracy beliefs and perceptions of other UK parents’ beliefs with actual normative belief levels. Parents receiving the normative feedback showed significantly reduced personal belief in anti-vaccine conspiracy beliefs at immediate post-test. As hypothesised, changes in normative perceptions of anti-vaccine conspiracy beliefs mediated the effect of the intervention. The intervention, did not directly increase vaccination intentions, however mediation analysis showed that the normative feedback increased perceptions of other parents’ vaccination intentions, which in turn increased personal vaccination intentions. No significant effects remained after a six-week follow-up. The current research demonstrates the potential utility of Social Norms Approach interventions for correcting misperceptions and reducing anti-vaccine conspiracy beliefs among UK parents. Further research could explore utilising a top-up intervention to maintain the efficacy.
