项目摘要

DESCRIPTION (provided by applicant): Significant racial disparities exist in the incidence and mortality rates of cervical cancer in the US, despite an overall decline in these rates for the population as a whole. In particular, African American women are significantly more likely to get and die from cervical cancer than non-Hispanic White women. African Americans, however, are also among the group that holds the least favorable attitudes toward the new human papillomavirus (HPV) vaccine recommended for young women to prevent cervical cancer. There is a tremendous need for developing effective communication interventions about HPV vaccination targeting caretakers of vaccine-eligible young African American women. Previous research indicates that framing a health message in terms of the benefits that may be achieved by performing the recommended behavior versus the costs that may be incurred by not following the recommendation could systematically influence message efficacy. Despite extensive research on message framing, little is known about the effects of message framing on HPV vaccination acceptance among caretakers of vaccine-eligible young African American women and the extent to which these effects may be moderated by the caretakers' vaccine-related beliefs such as perceived vaccine safety and efficacy. To advance scientific knowledge on how message framing can be used to foster HPV vaccination acceptance in African American communities, we will conduct a community-based randomized trial with 150 caretakers of vaccine-eligible young African American women ages 9-17 to assess the relative efficacy of gain- vs. loss-framed messages. The proposed project will provide useful insights into the design of targeted messages to improve HPV vaccination acceptance among caretakers of vaccine-eligible young African American women. This study will also set the stage for a program of research aimed at developing theory-based communication interventions for promoting HPV vaccination in African American communities, with the ultimate goal of reducing and eliminating racial disparities in cervical cancer incidence and mortality rates.

描述（由申请人提供）：美国宫颈癌的发病率和死亡率存在显著的种族差异，尽管总体人群的这些比率总体下降。特别是，非裔美国女性患宫颈癌和死于宫颈癌的可能性明显高于非西班牙裔白色女性。然而，非洲裔美国人也是对推荐给年轻女性预防宫颈癌的新型人乳头瘤病毒（HPV）疫苗持最不赞成态度的群体之一。有一个巨大的需要，制定有效的沟通干预措施，针对HPV疫苗接种的照顾者的疫苗合格的年轻非洲裔美国妇女。先前的研究表明，根据执行建议行为可能获得的收益与不遵循建议可能产生的成本来构建健康信息可能会系统地影响信息功效。尽管对信息框架进行了广泛的研究，但人们对信息框架对符合接种条件的年轻非洲裔美国妇女的看护人接受HPV疫苗接种的影响知之甚少，以及这些影响可能在多大程度上受到看护人疫苗相关信念的影响，例如感知疫苗的安全性和有效性。为了推进关于如何使用信息框架来促进非裔美国人社区接受HPV疫苗接种的科学知识，我们将进行一项以社区为基础的随机试验，其中有150名9-17岁符合疫苗条件的年轻非裔美国妇女的看护人，以评估获得与损失框架信息的相对功效。拟议的项目将为有针对性的信息设计提供有用的见解，以提高符合接种条件的年轻非洲裔美国妇女的照顾者对HPV疫苗接种的接受程度。这项研究还将为一项研究计划奠定基础，该计划旨在开发基于理论的沟通干预措施，以促进非裔美国人社区的HPV疫苗接种，最终目标是减少和消除宫颈癌发病率和死亡率的种族差异。
