Media Detective is a 10-lesson elementary school substance use prevention program developed on the basis of the message interpretation processing model designed to increase children's critical thinking skills about media messages and reduce intent to use tobacco and alcohol products. The purpose of this study was to conduct a short-term, randomized, controlled trial to evaluate the effectiveness of Media Detective for achieving these goals.
Elementary schools were randomly assigned to conditions to either receive the Media Detective program (n=344) or serve in a waiting list control group (n=335).
Boys in the Media Detective group reported significantly less interest in alcohol-branded merchandise than boys in the control group. Also, students who were in the Media Detective group and had used alcohol or tobacco in the past reported significantly less intention to use and more self-efficacy to refuse substances than students who were in the control group and had previously used alcohol or tobacco.
This evaluation provides evidence that Media Detective can be effective for substance use prevention in elementary school-aged children. Notably, media-related cognitions about alcohol and tobacco products are malleable and relevant to the development and maintenance of substance use behaviors during late childhood. The findings from this study suggest that media literacy-based interventions may serve as both a universal and a targeted prevention program that has potential for assisting elementary school children in making healthier, more informed decisions about use of alcohol and tobacco products.
媒体侦探是一个由 10 节课组成的小学药物使用预防计划,它基于信息解释处理模型开发,旨在提高儿童对媒体信息的批判性思维能力,并减少使用烟草和酒精产品的意图。本研究的目的是进行短期、随机、对照试验,以评估媒体侦探在实现这些目标方面的有效性。
小学被随机分配到接受媒体侦探计划(n=344)或等待名单对照组(n=335)的条件。
接受媒体侦探计划的男孩比对照组男孩对酒精品牌商品的兴趣明显减少。此外,过去曾使用过酒精或烟草的媒体侦探组学生报告的使用意图和拒绝物质的自我效能感明显低于对照组和过去曾使用过酒精或烟草的学生。
这项评估提供了证据表明,媒体侦探可以有效地预防小学生的药物使用。值得注意的是,与酒精和烟草产品相关的媒体认知是可塑的,与儿童晚期药物使用行为的发展和维持有关。这项研究的结果表明,基于媒体素养的干预措施可能是一种通用的和有针对性的预防计划,有可能帮助小学生做出更健康、更明智的关于使用酒精和烟草产品的决定。
