This longitudinal study reports on the development and evaluation of a narrative intervention aimed at increasing human papillomavirus (HPV) vaccination among college women. The prevention of HPV is a public health priority due to its pervasiveness and relationship to cervical cancer, the second leading cause of cancer deaths among women worldwide. Pilot work utilizing culture-centric narrative theory guided development of the intervention content. Exemplification theory led to hypotheses comparing communication sources of the narrative messages (peer only, medical expert only, or a combination of the two source types) in a four-arm randomized controlled trial (N = 404; 18-26 year olds). The combined peer-expert narrative intervention nearly doubled vaccination compared to controls (22% vs. 12%). The pragmatic goal of increasing HPV vaccination and the theoretical predictions about message source were supported. As predicted, the inclusion of peer and medical expert sources plays a critical role in promoting HPV vaccination among college women. Furthermore, the intervention increased HPV vaccination by increasing vaccine self-efficacy and intent. Theoretical and practical implications for designing effective HPV vaccine messages are discussed.
本纵向研究报告了一项叙事干预措施的发展和评估，该措施旨在提高大学生群体中的 HPV 疫苗接种率。预防 HPV 是一项公共卫生重点，因为 HPV 普遍存在且与宫颈癌有关，宫颈癌是全世界女性癌症死亡的第二大主要原因。利用以文化为中心的叙事理论进行的初步工作指导了干预内容的开发。例证理论导致了对叙事信息传播源（仅同伴、仅医学专家或两种来源类型的组合）进行比较的假设，这些假设在一项四臂随机对照试验（N=404；18-26 岁）中进行了检验。与对照组相比，联合使用同伴-专家叙事干预措施使接种率几乎翻了一番（22%对 12%）。这一结果支持了增加 HPV 疫苗接种率的实际目标和关于信息来源的理论预测。正如预测的那样，同伴和医学专家来源的纳入在促进大学生群体中的 HPV 疫苗接种方面发挥了关键作用。此外，该干预措施通过提高疫苗效能和接种意愿来增加 HPV 疫苗接种率。本文讨论了设计有效 HPV 疫苗接种信息的理论和实践意义。
