BACKGROUND School-based comprehensive sexual health education can improve adolescent health outcomes, and web-based programs are a promising approach to overcoming challenges associated with teacher-led formats by ensuring that students receive content that is consistent, unbiased, and medically accurate. However, many adolescents do not receive high-quality sexual health education and turn to the media for information about sex and relationships. Consumption of sexual media messages is related to early and risky sexual behaviors. Media literacy education (MLE) is a proven approach to adolescent sexual health promotion, yet there are no rigorously evaluated web-based MLE programs to promote sexual and relationship health among high school students. METHODS This study will test the efficacy, in a randomized controlled trial, of Media Aware, a web-based comprehensive sexual health promotion program for high school students that uses an MLE approach. Participants will be students in 9th and 10th grade health classes in participating schools. Randomization will take place at the school level, and data collection will take place at three time points (i.e., pretest, posttest, and 3 months follow-up). Students in the intervention classrooms will receive Media Aware between pretest and posttest, and students in the delayed-intervention classrooms will receive Media Aware after study completion (i.e., after 3 months follow-up data collection). Students in the delayed-intervention classes will receive their standard health education programming, and teachers in the delayed-intervention classes will be asked to refrain from teaching sexual health or MLE during the study timeframe. The primary outcome variables are intentions, willingness, and behaviors related to sexual health and sexual activity. DISCUSSION There are currently no evidence-based comprehensive sexual health programs for high school students that are web-based and use an MLE approach. Media Aware has the potential to be an engaging, less expensive, and effective sexual and relationship health program for high school students. Media Aware is unique in two important ways: (1) the web-based format reduces many of the challenges to fidelity of implementation associated with teacher-led sexual health education; and (2) the MLE approach addresses a commonly ignored influence on adolescent sexual and relationship health, namely, media.

一项随机对照试验的研究方案，以评估针对高中生的基于Web的综合性健康和媒体素养教育计划。

背景技术基于学校的全面性健康教育可以改善青少年的健康状况，基于网络的程序是一种有前途的方法，可以通过确保学生获得一致，公正且医学上准确的内容来克服与教师主导的格式相关的挑战。但是，许多青少年未接受高质量的性健康教育，因此向媒体寻求有关性和性关系的信息。性媒体信息的消费与早期和危险的性行为有关。媒体素养教育（MLE）是一种促进青少年性健康的行之有效的方法，但是还没有经过严格评估的基于Web的MLE程序来促进中学生的性健康和性健康。方法本研究将在一项随机对照试验中测试Media Aware，一种基于网络的针对高中生的全面性健康促进计划，该计划采用MLE方法。参加者将是参与学校的9年级和10年级健康班的学生。随机化将在学校一级进行，数据收集将在三个时间点进行（即前测，后测和3个月的随访）。干预教室的学生将在预测和后测之间获得Media Aware，而延迟干预教室的学生将在研究完成后（即3个月的跟踪数据收集后）获得Media Aware。延迟干预班的学生将接受他们的标准健康教育计划，并且要求延迟干预班的老师在学习时间内不要教授性健康或MLE。主要的结果变量是与性健康和性活动有关的意图，意愿和行为。讨论当前没有针对基于网络并使用MLE方法的高中生基于证据的综合性健康计划。Media Aware有可能成为针对高中生的一种引人入胜，价格便宜且有效的性健康和人际关系健康计划。Media Aware在两个重要方面具有独特性：（1）基于Web的格式减少了与以教师为主导的性健康教育相关的保真实施的许多挑战；（2）MLE方法解决了对青少年性行为和人际关系健康（即媒体）的普遍忽略的影响。试验注册ClinicalTrials.gov，NCT04035694。于2019年7月29日注册。科学查询联系人：Tracy Scull，博士（首席研究员）；位于美国北卡罗来纳州达勒姆（Durham）的5316 Highgate Drive，Suite 121，美国27713；tscull@irtinc.us。
