A huge and diverse amount of information is available online. In 4 studies, we provided complementary evidence about the psychosocial processes involved in online information gathering about vaccinations and the associated relation with trust in their safety. Study 1 investigated the relation between Italian Google inquiries and vaccine coverage for 0- to 2-year-old Italian children from 2000 and 2015, showing a correlation that turned negative over time. In Study 2, participants randomly assigned to a message providing a dual perspective (false balance condition) endorsed more conspiracy beliefs, which, in turn, reduced trust in vaccines compared with provaccine, antivaccine, and control messages. In Study 3, participants actively selected Google outputs that were in line with their opinion, and this confirmatory bias was particularly strong among participants distrusting vaccination. This association was disrupted by the exposure to provaccine messages, but only if antivaccine alternatives were absent. In Study 4, exposure to online comments questioning the human papilloma virus vaccination influenced attitudes toward the vaccination in a sample of not-yet-vaccinated young women. Practical implications for the way that media cover vaccination topics and for interventions addressing vaccine hesitancy are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
大量且多样化的信息可在线获取。在 4 项研究中，我们提供了关于接种疫苗相关信息在线收集过程中的心理社会因素及其与安全性信任之间关系的补充证据。研究 1 调查了 2000 年至 2015 年期间意大利谷歌搜索与意大利 0 至 2 岁儿童疫苗接种覆盖率之间的关系，结果显示这种相关性随着时间的推移而变为负相关。在研究 2 中，参与者被随机分配到一个提供双重观点的信息（虚假平衡条件），他们更赞同阴谋论，而与支持疫苗、反疫苗和对照信息相比，这降低了对疫苗的信任。在研究 3 中，参与者主动选择与自己观点一致的谷歌搜索结果，而在对疫苗接种不信任的参与者中，这种确认偏误尤为强烈。这种关联被暴露于支持疫苗的信息所破坏，但只有在不存在反疫苗替代信息时才会如此。在研究 4 中，对质疑人乳头瘤病毒疫苗接种的在线评论的接触影响了尚未接种疫苗的年轻女性样本对该疫苗接种的态度。讨论了针对媒体报道疫苗接种主题和解决疫苗犹豫的干预措施的实际意义。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
