Media Literacy Intervention for Indoor Tanning Prevention

描述（由申请人提供）：暴露在室内晒黑的紫外线下会增加患黑色素瘤的风险，黑色素瘤是一种致命的皮肤癌。尽管有风险，年轻女性还是经常去室内晒黑设施。研究表明，晒黑的社会规范与室内晒黑行为有关，而晒黑的社会规范的一个重要来源是大众媒体。然而，到目前为止，很少有研究调查如何解决媒体的影响和社会规范的室内晒黑。我们建议通过评估一种新的室内晒黑预防方法，媒体素养干预（MLI）来解决这一知识差距。在MLI中，参与者将首先批判性地分析影响社会规范的媒体的内容和功能（分析），并在此基础上开发反信息，以帮助自己和同伴抵制媒体影响和社会规范（生产）。此外，我们还将利用创新的制作方法：数字故事制作和数字论证制作。通过评估这些新的生产方法的有效性，我们寻求改善目前的MLI。除了确定MLI和数字故事制作的功效外，我们还将研究其认知，情感和社会过程。一项分组随机对照试验将评估MLI的疗效。参加者将是联谊会成员妇女（年龄18-24岁），聚集在他们的章节（K=36）。我们将随机分配女生联谊会章节到一个MLI与数字故事生产组（k=12），一个MLI与数字参数生产组（k=12），和一个评估只控制组（k=12）。干预措施将于10月交付。在12月的2个月、2月的4个月和4月的6个月，将两种MLI相互比较并与对照组比较室内晒黑率。中介分析将检查干预效果的假设过程。如果有效的话，这项研究可以告知未来的干预措施，在广泛的领域如何利用媒体扫盲和参与性生产的反信息，使社区成员能够抵制有害的媒体影响和社会规范。

DESCRIPTION (provided by applicant): Exposure to the ultraviolet rays of indoor tanning increases the risk of melanoma, the fatal form of skin cancer. Despite the risk, young women frequent indoor tanning facilities. Research indicates that protanning social norms are associated with indoor tanning behavior and that an important source of protanning social norms is the mass media. To date, however, little research has investigated how to address the media effects and social norms on indoor tanning. We propose to address this gap in knowledge by evaluating a novel approach to indoor tanning prevention, media literacy interventions (MLIs). In the MLIs, participants will first critically analyze the content and functons of the media influencing protanning social norms (analysis) and on this basis will develop counter-messages to help themselves and peers resist protanning media effects and social norms (production). Furthermore, we will utilize innovative approaches to production: digital story production and digital argument production. By evaluating the efficacy of these novel approaches to production, we seek to improve the current MLIs. In addition to determining the efficacy of MLIs and digital story production, we will examine their cognitive, affective, and socil processes. A group-randomized controlled trial will evaluate the efficacy of the MLIs. Participants will be sorority member women (ages 18-24), clustered within their chapters (K=36). We will randomly assign sorority chapters to an MLI with digital story production group (k=12), an MLI with digital argument production group (k=12), and an assessment-only control group (k=12). The interventions will be delivered in October. The two MLIs will be compared against each other and against the control group in indoor tanning rates at 2 months in December, 4 months in February, and at 6 months in April. Mediation analyses will examine the postulated process of intervention effects. If effective, this study could inform future interventions in broad fields about how to use media literacy and participatory production of counter messages to empower community members to resist harmful media effects and social norms.
