Community-based Design and Evaluation of a Conversational Agent to Promote SARS-COV2 Vaccination in Black Churches

项目摘要/摘要 基于社区的SARS宣传对话主体的设计与评价 黑教堂接种柯萨奇病毒2型疫苗 非洲裔美国人在新冠肺炎上遭受了不成比例的负担， 与白人相比，他们的感染率、住院率和死亡率更高。这些发现可能 非洲裔美国人也有更高的疫苗迟疑风险，这一事实使情况更加复杂。 由于有限的健康素养已被确定为种族和族裔差异的关键调解人， 解决健康素养障碍的干预措施有可能改善这些障碍 差距。在过去的十年中，我们已经开发和测试了具体化的会话代理 (ECA)-模拟面对面咨询的计算机角色，使用语音、手势、 凝视暗示和其他非语言行为，并成功地将它们用于健康行为 针对健康素养低的人群的干预措施。我们已经开发了基于ECA的 干预措施，以解决低识字率人群中的广泛健康问题， 包括体育活动、饮食和服药依从性促进，提供获得和 医疗保健文件的解释和家庭健康史的收集。在这个项目中，我们 建议创建有效且可持续的基于智能手机的ECA干预，旨在 提供有关SARS-CoV-2和流感疫苗接种的个性化和量身定制的教育。我们 将与大波士顿的黑人部长联盟TenPoint(BMATP)合作开发 干预应用程序并在一项临床试验中对其进行评估，该试验涉及来自12个国家的600名会众 以非裔美国人为主的教堂。我们的主要假设是，参与者将拥有 SARS-CoV-2和流感疫苗系列在6个月内完成得更多(上半年) 和12个月(H2)在促进参与度和融入精神的应用程序版本中 裁缝。我们的第二个假设是，在没有接种疫苗的参与者中， 那些处于高参与度和量身定做的条件下的人在意图上将有显著的改善 接种SARS-CoV-2和流感疫苗以及对SARS-CoV-2和 接种流感疫苗。

PROJECT SUMMARY/ABSTRACT Community-based Design and Evaluation of A Conversational Agent to Promote SARS- COV2 Vaccination in Black Churches African Americans have suffered a disproportionate burden from COVID-19, with significantly higher rates of infection, hospitalization, and mortality compared to Whites. These findings may be compounded by the fact that African Americans are also at higher risk for vaccine hesitancy. As limited health literacy has been identified as a key mediator of racial and ethnic disparities, interventions that address health literacy barriers have the potential to ameliorate these disparities. Over the past decade we have developed and tested embodied conversational agents (ECA) — computer characters that simulate face-to-face counseling using voice, hand gesture, gaze cues and other nonverbal behavior, and successfully used them in health behavior interventions for populations with low health literacy. We have developed ECA-based interventions to address a wide range of health problems among low literacy populations, including physical activity, diet, and medication adherence promotion, providing access to and explanation of healthcare documents, and collection of family health histories. In this project, we propose to create an effective and sustainable smartphone-based ECA intervention designed to deliver personalized and tailored education about SARS-CoV-2 and Influenza vaccination. We will collaborate with the Black Ministerial Alliance TenPoint (BMATP) of Greater Boston to develop the intervention app and evaluate it in a clinical trial involving 600 congregants from 12 predominately African American churches. Our primary hypothesis is that participants will have significantly greater SARS-CoV-2 and Influenza vaccination series completion at 6 months (H1) and 12 months (H2) in versions of the app that promote engagement and incorporate spiritual tailoring. Our secondary hypotheses are that, among participants who have not been vaccinated, those in the high engagement and tailored conditions will have significant improvements in intent to obtain SARS-CoV-2 and Influenza vaccination and attitudes towards SARS-CoV-2 and Influenza vaccination.
