Vaccine hesitancy is a substantial barrier to increasing HPV vaccination rates among Latinx in the US who experience disproportional rates of HPV-related cancers. The current research tests the effectiveness of culturally-targeted, fear-appeal messages designed using the Extended Parallel Processing Model (EPPM). We compared differences among Latinx young adults and parents of adolescents of the effectiveness of messages that highlight HPV-related cancers, genital warts, or a control condition to promote online information seeking about the HPV vaccine-a known precursor to vaccination intention. Results found messages containing EPPM messaging elements produced significantly higher self-reported intention to seek information about HPV vaccines in comparison to a control message group. However, participants who received control messages had the highest percentage of hyperlink clicks to more information about HPV (a novel measure of information seeking). Findings suggest that fear appeals may be effective for promoting information seeking about HPV vaccination, which in turn could increase vaccine utilization, among Latinx participants.

疫苗犹豫是美国拉丁裔人群中 HPV 疫苗接种率增加的一个重大障碍，因为他们 HPV 相关癌症的发病率不成比例。目前的研究测试了使用扩展平行处理模型 (EPPM) 设计的针对特定文化、以恐惧诉求为重点的信息的有效性。我们比较了 HPV 相关癌症、生殖器疣或对照条件信息对促进 HPV 疫苗在线信息搜索的有效性在拉丁裔年轻成年人和青少年父母中的差异——这是接种疫苗意愿的已知前提。结果发现，与对照组信息相比，包含 EPPM 信息元素的信息明显提高了自我报告的 HPV 疫苗信息搜索意向。然而，收到对照组信息的参与者对更多 HPV 信息的超链接点击比例最高（这是信息搜索的一个新措施）。研究结果表明，恐惧诉求可能对促进拉丁裔参与者对 HPV 疫苗接种的信息搜索有效，从而增加疫苗的使用。临床试验注册号（NCT05206669）于 2022 年 1 月 25 日回溯注册。
