Research on vaccination hesitancy has been extensive, but the role of information processing in decision making still needs to be explored. The study examines the alignment between parents' COVID-19 vaccination intentions and actual behavior, focusing on the impact of different kinds of information processing on the consistency or inconsistency of these behaviors. It analyzes parents' reliance on health information sources, and education levels, with institutional trust, ability to critically evaluate conspiracy theories and scientific knowledge as moderators. A total of 1118 Israeli parents participated in digital surveys and were classified into the following 4 groups based on their initial vaccination intentions and actual behaviors: (1) consistent-pro-vaccine and vaccinated; (2) inconsistent-pro-vaccine but unvaccinated; (3) inconsistent-anti-vaccine but vaccinated; and (4) consistent-anti-vaccine and unvaccinated). The results show that consistent parents process information using system 1, i.e., heuristic information processing, reliance on health information sources, moderated by institutional trust and education. However, inconsistent parents used systems 1 and 2, namely heuristic-systematic information processing, influenced by knowledge of COVID-19 and the ability to assess conspiracy theories critically.
关于疫苗犹豫的研究已经很广泛，但信息处理在决策中的作用仍有待探索。该研究考察了父母对新冠疫苗接种的意愿与实际行为之间的一致性，重点关注不同类型的信息处理对这些行为一致性或不一致性的影响。研究分析了父母对健康信息来源的依赖程度、教育水平，以及机构信任、批判性评估阴谋论的能力和科学知识作为调节因素的作用。共有1118名以色列父母参与了数字调查，并根据他们最初的疫苗接种意愿和实际行为被分为以下4组：（1）支持疫苗接种且已接种；（2）支持疫苗接种但未接种；（3）反对疫苗接种但已接种；（4）反对疫苗接种且未接种。结果表明，态度一致的父母使用系统1进行信息处理，即启发式信息处理，对健康信息来源的依赖程度受机构信任和教育的调节。然而，态度不一致的父母使用系统1和系统2，即启发式-系统性信息处理，受新冠知识和批判性评估阴谋论能力的影响。
