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

描述（由申请人提供）：不插电和媒体悟性本研究将开发和测试不插电和媒体悟性的可行性，这是一种多层次的干预措施，旨在减少久坐行为，并最大限度地减少媒体对食品宣传的影响。该项目将侧重于政策、环境和行为变化，以减少儿童、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的媒体素养课程，以建立对食品广告进行批判性评估的技能，并减少购买高度广告化的能量密集型食品。干预措施将汇集五项创新举措，（1）30天生存！，一个让学生在一个月内放弃电视的课程，（2）一个基于教师驱动的发展模式的媒体素养课程，该模式源于以前对其他儿童健康问题的研究，（3）基于学生家庭目标的家庭教育。并与教师和家长的连续工作组一起使用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，以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不插电工具包，并与管理员和家长团体合作，在全校范围内实施不插电和媒体悟性的组成部分。我们将收集定量和定性的过程结果数据，以监测实施和评估的完整性。我们将比较干预学校五个四年级和五年级教室的学生成绩，以及学生和家庭期望、自我效能和行为能力的五个方面的变化。我们还将测量体育活动的时间以及学生和家庭购买高度广告食品的时间。这项可行性研究的结果将用于计划一项有大量学校参加的随机析因试验。不插电项目叙事不插电和媒体悟性是一个以学校为基础的干预，以减少久坐不动的行为，并尽量减少摄入高度广告的能量密集的食物。这一多层次的举措将促进政策和环境的变化，以利于儿童、家庭和学校，并发展媒体扫盲技能。

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.
