DESCRIPTION (provided by applicant): The purpose of this study is to examine the impact of television on adolescent sleep/wake patterns in the context of a controlled experiment with Vietnamese villages lacking both television and electricity. Accumulating evidence indicates that increasing numbers of adolescents are going to bed later and getting by on less than optimal sleep in most areas of the globalizing world. The convergence of maturational processes with media access and related social changes appear to play a role in these trends. The research plan builds on a unique opportunity to identify social-ecological factors that contribute to the development of adolescent sleep and circadian changes within a randomized experimental design. Introducing television will combine biological and social stimuli via access to lighted screens and engaging stimuli, with altered social interactions around television watching. We will examine sleep patterns and associated neurobehavioral and health statuses in all adolescents aged 12-18 (n=107) residing in a matched pair of experimental television-receiving and control villages. Actigraphy in adolescents will be combined with measures of pubertal status, behavioral alertness, sleep quality, school attendance and performance, and mental and physical health. The study design puts adolescent sleep behavior in social context at 3 levels of analysis, family (household), community (village), and culture (Vietnamese Tai). Household measures include adolescent and parent sleep habits, daily routines, perceived well-being, and GPS tracking to gauge time at key sites (television, home, school, fields), time together, and ranging distance. Village-wide data on each community member are collected in the main project, which this study will join. Measures relevant to our hypotheses include amount of television viewing, GPS-mapped social geography, demographics, and perceived stress, life satisfaction and social status. Ongoing ethnography probes sleep attitudes, practices, and meanings. This research will provide the first direct test for causal links between television and changes in adolescent sleep. We test whether television-watching youth show changed sleep timing, amount, and quality; whether puberty, gender, and parental monitoring influence these effects; and whether school performance and health indices suffer. Findings will directly address questions about whether and how developmental processes (puberty) interact with social ecology (community-level television introduction and household-level conditions) to produce adolescent vulnerability to sleep restriction and disruption, and with what functional and health consequences. Previous research on these questions has been hampered by inability to establish causal influences: we capitalize on a randomized experiment to overcome that difficulty.

描述（由申请人提供）：本研究的目的是在缺乏电视和电力的越南村庄进行对照实验的背景下，研究电视对青少年睡眠/觉醒模式的影响。越来越多的证据表明，在全球化世界的大多数地区，越来越多的青少年上床睡觉时间较晚，并且睡眠质量不佳。成熟过程与媒体接触和相关社会变革的融合似乎在这些趋势中发挥了作用。该研究计划基于一个独特的机会，在随机实验设计中确定有助于青少年睡眠发展和昼夜节律变化的社会生态因素。电视的引入将通过点亮屏幕和吸引人的刺激来结合生物刺激和社会刺激，并改变围绕电视观看的社交互动。我们将检查居住在一对匹配的实验电视接收村和控制村中的所有 12-18 岁青少年 (n=107) 的睡眠模式以及相关的神经行为和健康状况。青少年体动记录仪将与青春期状态、行为警觉性、睡眠质量、学校出勤率和表现以及心理和身体健康等指标结合起来。研究设计将青少年睡眠行为置于社会背景下，从家庭（家庭）、社区（村庄）和文化（越南傣族）三个层面进行分析。家庭测量包括青少年和父母的睡眠习惯、日常生活、感知的幸福感以及用于测量关键地点（电视、家庭、学校、田野）的时间、在一起的时间和测距距离的 GPS 跟踪。本研究将加入的主要项目收集了每个社区成员的全村数据。与我们的假设相关的衡量标准包括电视观看量、GPS 地图社会地理、人口统计数据以及感知压力、生活满意度和社会地位。正在进行的民族志探讨睡眠态度、实践和意义。这项研究将为电视与青少年睡眠变化之间的因果关系提供首次直接测试。我们测试观看电视青年节目是否改变了睡眠时间、数量和质量；青春期、性别和父母监督是否会影响这些效果；学校表现和健康指数是否受到影响。研究结果将直接解决以下问题：发育过程（青春期）是否以及如何与社会生态（社区层面的电视介绍和家庭层面的条件）相互作用，从而导致青少年容易受到睡眠限制和干扰，以及产生什么功能和健康后果。先前对这些问题的研究因无法确定因果影响而受到阻碍：我们利用随机实验来克服这一困难。
