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，黑色素瘤是皮肤癌的致命形式。尽管存在风险，年轻女性还是经常使用室内日光浴设施。研究表明，晒黑社会规范与室内晒黑行为有关，而且晒黑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对室内晒黑的影响和社会规范。我们建议通过评估一种预防室内晒黑的新方法--媒体识字干预(MLIS)来解决这一知识缺口。在MLIS中，参与者将首先批判性地分析影响亲子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，以帮助自己和同龄人抵制亲子媒体效应和社会规范(生产)。此外，我们将利用创新的制作方法：数字故事制作和数字论点制作。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和数字故事制作的有效性外，我们还将检查它们的认知、情感和文体过程。一项分组随机对照试验将评估MLIs的疗效。参与者将是女生联谊会成员(18-24岁)，聚集在她们的分会(K=36)内。我们将随机分配给MLI数字故事制作组(k=12)、MLI数字论点制作组(k=12)和仅评估对照组(k=12)。干预措施将于10月份发布。这两个MLI将在12月份的2个月、2月份的4个月和4月份的6个月的室内晒黑率进行相互比较，并与对照组进行比较。调解分析将考察干预效果的假设过程。如果有效，这项研究可以为未来广泛领域的干预措施提供信息，说明如何利用媒体扫盲和参与性制作反信息来增强社区成员抵制有害媒体影响和社会规范的能力。

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.
