Digital Assessment Core

项目总结/摘要 以前的儿童TDM使用和睡眠的研究经常依赖于这些行为的父母报告。 家长报告的儿童TDM使用要么是非常简短和不准确（报告典型的使用约3 问题）或非常劳动密集型，要求家长积极报告他们的孩子的TDM使用每15 白天的时间（TDM日记）。这两种情况都可能导致儿童电视收视率的严重低估和高估 或移动终端使用。利用数字传感器的进步，这些传感器允许客观和被动（即， 需要父母或孩子很少或根本不需要努力）评估TDM使用和睡眠/活动行为，DA- 核心将通过确保对儿童TDM和睡眠的高质量评估来支持整个计划。 项目1、2和3。具体来说，项目1将使用FLASH-TV和跟踪移动终端使用的应用程序 和腕戴式加速计，以检查儿童TDM的量、时间和类型之间的关联 用于儿童睡眠。使用与项目1相同的队列和TDM使用评估，项目2将检查 TDM使用对儿童执行功能和体重状况的影响，并检查调节作用 父母可以玩。项目3系统地研究了儿童使用移动终端的时间对儿童健康的影响， 睡前的家庭环境对他们的昼夜节律定时、睡眠（如通过可穿戴设备在 家庭）和执行功能。DA核心将通过确保高质量的 客观和被动（即，几乎不需要父母或孩子的努力）评估儿童的TDM， 在项目1、2和3之间睡觉。DA核心将建立一个可持续的，多学科的核心服务 数字传感器和可穿戴设备使用的当前建议和未来研究。目标和 核心的目标将包括设备库存的管理和维护（即，闪光电视 和活动记录仪），对工作人员进行评估程序培训，处理数据，进行质量控制 程序，以确保数据的质量，整合数据在我们的各种平台，以允许小时- 对TDM使用和休息/活动模式的相互作用进行小时检查，并储存和维护 在安全数据服务器上的原始、处理和提取的数据可由所有核心，项目， 以及各机构的团队成员。这个应用程序的过度扩展目标是推出一个可持续的 一个多学科的研究项目，以有力地调查TDM使用对一个人的短期和长期影响。 学龄前儿童的睡眠、昼夜节律、EF和体重状况的不同样本。的项目和 与该研究计划一起建立的核心将允许研究小组解决每个核心的具体目标， 项目，除了使我们能够寻求额外的资金，继续跟踪这批学龄前儿童 在更长的时间内。未来对这些儿童开始使用TDM的客观评估 小学，然后进入中学将大大提高我们的理解的影响， TDM的使用，无论是好是坏，对儿童的健康和发展。

PROJECT SUMMARY/ABSTRACT Previous studies of children’s TDM use and sleep have frequently relied on parent-report of these behaviors. Parent reporting of children’s TDM use is either very brief and inaccurate (reporting typical use with about 3 questions) or very labor intensive, requiring parents to actively report on their child’s TDM use every 15 minutes during the day (TDM diaries). Both can lead to gross under and over-reporting of children’s TV viewing or mobile device use. Leveraging advances in digital sensors which permit the objective and passive (i.e., requiring little to no effort by the parent or child) assessment of TDM use and sleep/activity behaviors, the DA- Core will support the overall program by ensuring high-quality assessment of children’s TDM and sleep across Projects 1, 2, and 3. Specifically, Project 1 will use FLASH-TV, and applications that track mobile device use and wrist worn accelerometer to examine the association of the amount, timing, and type of children’s TDM use on children’s sleep. Using the same cohort and TDM use assessment as Project 1, Project 2 will examine the impact of TDM use on children’s executive functioning and weight status, and examine the moderating role parents can play. Project 3 systematically examines the impact of the timing of children’s mobile device use in the home environment before bed on their circadian timing, sleep (as measured by wearable devices in the home), and executive functioning. The DA-Core will support the overall program by ensuring high-quality objective and passive (i.e., requiring little to no effort by the parent or child) assessment of children’s TDM and sleep across Projects 1, 2, and 3. The DA-Core will establish a sustainable, multi-disciplinary core to service the current proposal and future research in the use of digital sensors and wearable devices. Aims and objectives of the core will include management and maintenance of an inventory of devices (i.e., FLASH-TV and actigraphs), training staff in assessment procedures, processing of data, conducting quality control procedures to ensure the quality of the data, integration of data across our various platforms to allow for hour- to-hour examination of the interaction of TDM use and rest/activity patterns, and storage and maintenance of the raw, processed, and extracted data on a secure data server that is accessible by all of the cores, projects, and team members across institutions. The over-arching goal of this application is to launch a sustainable multi-disciplinary research program to robustly investigate the short- and long-term influence of TDM use on a diverse sample of preschool aged children’s sleep, circadian rhythms, EF, and weight status. The projects and cores established with this research program will permit the research team to address the specific aims of each project, in addition to position us to seek additional funding to continue to follow this cohort of preschoolers over a longer duration. Future objective assessment of TDM use among these children as they start elementary school and then move into middle school would greatly enhance our understanding of the impact of TDM use, whether good or bad, on children’s health and development.
