The human papillomavirus (HPV) vaccine is the most effective way to prevent HPV-related cancers. Integrating provider vaccine counseling is crucial to improving HPV vaccine completion rates. Automating the counseling experience through a conversational agent could help improve HPV vaccine coverage and reduce the burden of vaccine counseling for providers. In a previous study, we tested a simulated conversational agent that provided HPV vaccine counseling for parents using the Wizard of OZ protocol. In the current study, we assessed the conversational agent among young college adults (n=24), a population that may have missed the HPV vaccine during their adolescence when vaccination is recommended. We also administered surveys for system and voice usability, and for health beliefs concerning the HPV vaccine. Participants perceived the agent to have high usability that is slightly better or equivalent to other voice interactive interfaces, and there is some evidence that the agent impacted their beliefs concerning the harms, uncertainty, and risk denials for the HPV vaccine. Overall, this study demonstrates the potential for conversational agents to be an impactful tool for health promotion endeavors.

使用会话代理进行 HPV 疫苗咨询，检查年轻人的潜在可用性和健康信念

人乳头瘤病毒 (HPV) 疫苗是预防 HPV 相关癌症的最有效方法。整合提供者的疫苗咨询对于提高 HPV 疫苗完成率至关重要。通过对话代理自动化咨询体验可以帮助提高 HPV 疫苗覆盖率并减轻提供者的疫苗咨询负担。在之前的一项研究中，我们测试了一种模拟对话代理，该代理使用 OZ 向导协议为父母提供 HPV 疫苗咨询。在当前的研究中，我们评估了年轻大学生（n = 24）之间的对话代理，这些人可能在建议接种疫苗时在青春期错过了 HPV 疫苗。我们还对系统和语音的可用性以及有关 HPV 疫苗的健康信念进行了调查。参与者认为该代理具有较高的可用性，略优于或相当于其他语音交互界面，并且有一些证据表明该代理影响了他们对 HPV 疫苗的危害、不确定性和风险否认的信念。总体而言，这项研究表明对话代理有可能成为促进健康的有效工具。
