DESCRIPTION (provided by applicant): Exposure to entertainment media (TV, movies, music, video games and the Internet) has been associated with key adolescent health outcomes, including obesity, alcohol, and tobacco use, by a large body of research evidence. This research has been limited by weak data collection measures and a narrow focus on television viewing. Media use has grown and diversified dramatically, with youth growing up in media-rich environments, often multitasking with 2 or more media simultaneously. The broad, long-term objective of this study is to validate Measurement of Youth Media Exposure (MYME), a multimethod instrument designed to obtain a more sensitive and comprehensive assessment of adolescent use of and exposure to entertainment media. Its specific aims are to test the feasibility and acceptability of MYME, to assess MYME's reliability and validity, and to evaluate MYME's ability to predict key adolescent health risks of overweight, alcohol use, and tobacco smoking. MYME combines established, complementary methods of Recall Estimate (RE), Time-Use Diary (TUD), and Momentary Sampling (MS) so the strengths of each compensate for limitations of others. 150 youth 13 to 15 years old will complete a RE of their media exposure, alcohol and tobacco use status and have their height and weight measured on enrollment (RE0). They will carry a PDA and video camcorder for 1 week, responding to random signals by answering questions on their media exposure, including content, context and their state of mind, and video recording their environments, activities, and media exposures. On a randomly selected weekday and weekend day, participants will keep a 24 hour TUD of their activities, including media use, content, and context of use. At the end of the week, participants will return their equipment and execute RE1, recalling their media use over the past week. They will complete the full MYME protocol again after 1 week off, so that each MYME component and the whole measure can be evaluated for reliability and validity. One year after completing MYME, participants will be weighed and measured and will again complete RE0 assessing media exposure and substance use. This study will evaluate a more sensitive, comprehensive and accurate measurement of youth media exposure and key health outcomes with the goal of developing more effective prevention programs. PUBLIC HEALTH RELEVANCE: Young people's exposure to media has been linked to obesity, smoking, and alcohol use. However, it has been difficult to definitively characterize the relationships and to develop effective prevention and intervention strategies because research methods have focused on obsolete media technologies and use patterns. The proposed research will test an innovative method of obtaining a more sensitive and comprehensive measurement of media exposure in the multimedia environments and multitasking lifestyles of today's youth.

描述（由申请人提供）：大量研究证据与娱乐媒体（电视，电影，音乐，视频游戏和互联网）的接触（电视，电影，音乐，视频游戏和互联网）与关键的青少年健康结果（包括肥胖，酒精和烟草使用）有关。这项研究受到数据收集措施薄弱的限制，并且对电视观看的关注很小。媒体的使用急剧增长和多样化，青年在媒体富裕的环境中成长，通常同时使用2个或更多媒体来完成多任务。这项研究的广泛长期目标是验证对青年媒体暴露量（MYME）的测量，这是一种多途径仪器，旨在获得对青少年使用和对娱乐媒体的接触的更敏感，更全面的评估。它的具体目的是测试MYME的可行性和可接受性，评估MYME的可靠性和有效性，并评估MYME预测超重，酒精使用和烟草吸烟的主要青少年健康风险的能力。 MYME结合了已建立的互补召回估计方法（RE），时间使用日记（TUD）和瞬时抽样（MS），因此每种补偿其他人的限制的优势。 150名青年13至15岁的年轻人将完成媒体的暴露，酒精和烟草使用状态，并在注册时衡量其身高和体重（RE0）。他们将携带PDA和视频摄像机1周，通过回答有关其媒体曝光的问题，包括内容，上下文和他们的心态以及录制其环境，活动和媒体曝光的视频，从而响应随机信号。在一个随机选择的工作日和周末日，参与者将保留24小时的活动，包括媒体使用，内容和使用环境。在本周结束时，参与者将返回其设备并执行RE1，回顾过去一周的媒体使用。他们将在休息1周后再次完成完整的MYME协议，以便可以评估每个MYME组件和整个措施的可靠性和有效性。完成MYME一年后，将对参与者进行称重和测量，并再次完成RE0评估媒体的曝光和吸毒。这项研究将评估对青年媒体曝光和关键健康成果的更敏感，全面和准确的衡量，目的是制定更有效的预防计划。公共卫生相关性：年轻人接触媒体与肥胖，吸烟和饮酒有关。但是，由于研究方法专注于过时的媒体技术和使用模式，因此很难确定地表征这种关系并制定有效的预防和干预策略。拟议的研究将测试一种创新的方法，即在多媒体环境中对媒体暴露以及当今青年的多任务生活方式进行更敏感和全面的测量。
