Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19.
In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations.
The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages.
Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.
有效的健康沟通可以提高接种意愿。我们比较了 8 条可能影响父母为孩子接种 COVID-19 疫苗意愿的信息。
在 2021 年 8 月在美国进行的一项横断面调查中，通过在线调查，1837 名父母和法定监护人接触了 8 条信息（个人选择、获益/实际效益、非专家、医疗保健提供者推荐、利他主义/社区利益、安全性/有效性、安全性和有效性），以确定信息接收情况及其对为孩子接种疫苗意愿的影响。父母使用李克特量表回答了 10 个问题。我们计算了每条信息的优势比（OR），OR>1.0 表示与参考信息相比，参与者对后续陈述的同意程度更高。我们使用广义估计方程拟合有序逻辑回归比较了消息之间的结果。
在理解意图方面，个人选择信息的同意率最高（OR=2.10；95%CI，1.94-2.27），其次是医疗保健提供者推荐信息（OR=1.58；95%CI，1.46-1.71）。个人选择信息的记忆性、相关性和可信度最高。利他主义/社区利益信息紧随其后。利他主义/社区利益信息最有可能增加父母为孩子接种疫苗的意愿，向朋友和家人征求意见，并寻找更多信息。最能促使父母为孩子接种疫苗的信息取决于父母在接触测试信息之前接种疫苗的意愿。
具有个人选择、医疗保健提供者推荐和利他主义/社区利益主题的信息可以用于未来的信息宣传活动。需要进一步研究来完善与利他主义/社区利益相关的信息概念。
