Human papillomavirus (HPV) vaccination is routinely recommended for U.S. adolescents ages 11 to 12 years, yet vaccine coverage remains low. Text message HPV immunization reminders to parents have been effective with increasing uptake, but text messages directly to adolescents in order to increase HPV vaccination uptake are unknown. The purpose of this study was to examine the acceptability of text messages about HPV vaccination and message preferences among adolescents. Middle school students (n = 43) assisted in designing text messages to promote HPV vaccine among their peers. Through seven focus groups and two in-class surveys, we assessed students' knowledge of HPV vaccine, use of texting, and preferences for text messages and sources. The average age of participants was 13 years, and all were White (17 males, 26 females) in this rural setting. More than 70% used text messaging with a cell phone. The text message with the best composite score (M = 2.33, SD = 0.72) for likeability, trustworthiness, and motivation to seek more information was a gain frame emphasizing reduction in HPV infection if vaccinated against HPV. Text messages with lower scores emphasized threats of disease if not vaccinated. Participants (68%) preferred doctors as their information source. Text messaging to adolescents may be a strategy to improve HPV knowledge and vaccination.
人乳头瘤病毒（HPV）疫苗接种是美国11至12岁青少年的常规推荐，但疫苗接种率仍然很低。向家长发送HPV免疫接种提醒短信对于提高接种率很有效，但直接向青少年发送短信以提高HPV疫苗接种率的效果尚不清楚。本研究的目的是检验关于HPV疫苗接种的短信的可接受性以及青少年对短信的偏好。中学生（n = 43）协助设计了在同龄人中推广HPV疫苗的短信。通过七个焦点小组和两次课堂调查，我们评估了学生对HPV疫苗的了解、短信使用情况以及对短信和信息来源的偏好。参与者的平均年龄为13岁，在这个农村地区，所有人都是白人（17名男性，26名女性）。超过70%的人使用手机发短信。在亲和力、可信度和寻求更多信息的动机方面综合得分最高（M = 2.33，SD = 0.72）的短信是一个收益框架，强调接种HPV疫苗可降低HPV感染率。得分较低的短信强调了不接种疫苗的疾病威胁。参与者（68%）更喜欢医生作为他们的信息来源。向青少年发送短信可能是提高HPV知识和疫苗接种率的一种策略。
