Unplugged and Media Savvy: Reducing the Impact of "Screen" Time

描述(由申请人提供)：非插拔和媒体理解这项研究将开发和测试非插拔和媒体理解的可行性，这是一种多层次的干预措施，旨在减少久坐行为，并将媒体宣传食物的影响降至最低。该项目将重点关注政策、环境和行为变化，以减少个别儿童、家庭和学校对电视、视频游戏和电脑娱乐的使用。这项研究将包括学生和家庭媒体素养课程，以培养对食品广告的批判性评估技能，并减少对高广告、高能量密度食品的购买。这项干预将汇集五项创新举措，(1)30天生活！，这是一个学生在课堂上写日记，因为他们一个月不看电视；(2)媒体素养课程，基于教师驱动的发展模式，源于之前与其他儿童健康问题的工作；(3)基于学生的家庭目标的家庭教育；(3)在该项目中，我们与教师和家庭进行焦点小组讨论，并与学校管理人员进行访谈，以探索干预主题，并利用与连续的教师和家长工作组的迭代过程来开发课堂和家庭课程。我们还将与管理人员合作，制定示范学校政策。在第二年，我们与来自不同学区的五所干预学校合作，测试干预的每个组成部分的可行性。我们将培训和支持教师，使他们能够实施课堂课程，在学年期间向每个家庭邮寄六个未插电工具包，并与管理人员和家长团体合作，在全校范围内实施未插电和媒体精通组件。我们将收集定量和定性的过程结果数据，以监测执行和评价的完整性。我们将比较干预学校的五个四年级和五年级班级的学生在学生和家庭期望、自我效能感和行为能力方面的五个方面的变化。我们还将测量学生和家庭的体力活动时间和购买大量广告食品的时间。这项可行性研究的结果将被用来计划与大量学校进行的随机析因试验。不插电项目叙事不插电和媒体知晓是一项以学校为基础的干预措施，旨在减少久坐行为，并最大限度地减少广告宣传的高能量密度食物的摄入量。这一多层次倡议将促进改变针对个别儿童、家庭和学校的政策和环境，并培养媒体识字技能。

DESCRIPTION (provided by applicant): Unplugged and Media Savvy This study will develop and test the feasibility of Unplugged and Media Savvy, a multi-level intervention to reduce sedentary behavior and minimize the impact of media promotion of foods. The project will focus on policy, environmental and behavioral changes to reduce the use of TV, video games and computer entertainment by individual children, families and schools. This study will include student and family media literacy curricula to build skills for critical assessment of food advertising and reduce purchases of highly advertised, energy dense foods. The intervention will bring together five innovative initiatives, (1) 30 Days Live!, a program in which students journal as they give up television for a month as a class, (2) a media literacy curriculum based on a teacher-driven developmental model derived from previous work with other children's health issues, (3) family education based on family goals for student f the project we conduct focus groups with teachers and families and interviews with school administrators to explore intervention themes, and develop classroom and family curriculum using an iterative process with successive work groups of teachers and parents. We will also work with administrators to develop model school policies. In year two we work with five intervention schools from diverse school districts to test the feasibility of each of the components of the intervention. We will train and support teachers so that they can implement the classroom curricula, mail six Unplugged kits to each family during the school year, and work with administrators and parent groups to implement the school-wide components of Unplugged and Media Savvy. We will collect both quantitative and qualitative process outcome data to monitor the integrity of the implementation and evaluation. We will compare student outcomes in five fourth and fifth grade classrooms in intervention schools with five mude change in student and family expectations, self efficacy, and behavioral capacity. We will also measure hours of physical activity and student and family purchases of highly advertised foods. The results of this feasibility study will be used to plan a randomized factorial trial with a large number of schools. Unplugged Project Narrative Unplugged and Media Savvy is a school-based intervention to reduce sedentary behavior and minimize intake of highly advertised energy dense foods. This multilevel initiative will promote changes in policies and environments for individual children, families and schools and develop media literacy skills.
