Excessive screen-device use is linked with both physical health (i.e. obesity and cardiovascular risk) and mental health outcomes (i.e. depression and substance abuse) ostensibly through obesogenic health behaviors (i.e. poor sleep and sedentary behavior) and social/emotional risk factors (i.e. behavior problems). Advances in mobile technology have increased the availability of screens for young children (under 6), and screen time habits established in early childhood can persist through school age and into adulthood. Research on screen time use has been hindered by methodological limitations, including a reliance on retrospective self-reported measures (which are subject to recall and desirability biases). Additionally, the limited research on within-day time-varying contexts (i.e. child behavior, parenting stress) that influence screen time in specific situations, produces an unrefined picture of the mechanisms underlying the link between screen time and behavioral health outcomes. Utilizing data already collected by mobile devices is likely to provide a more objective and nuanced measure of screen time. Integrating intensive longitudinal data collected from multiple sources (i.e. passive mobile screen time sensing, ecological momentary assessment (EMA) and accelerometry) can reveal the process-oriented science that underlies the association between screen time and physical health behaviors (i.e. sleep & activity) and mental health (i.e. behavior problems). This study aims to test the feasibility/acceptability and utility of passively collecting objective mobile screen time data in conjunction with accelerometry and EMA among low income dyads of caregivers and their 3-5-year-old child over 30-days. Caregivers will complete EMA to assess screen time context including child behavior problems (i.e. compliance, tantrums) and parent stress. Validity of passive screen time sensing will be assessed using concurrent parent EMA report of screen time and sedentary behavior via accelerometry. Feasibility and acceptability will be assessed by examining predictors of compliance with passive sensing protocols and qualitative interviews respectively. Results will inform measurement and intervention strategies of a subsequent well powered trial to identify personalized targets for behavior interventions to prevent obesity and reduce health disparities. This project integrates well with the COBRE Research Center for Well-Being theme to dually address health and social-emotional behaviors in children.

过度使用屏幕设备与身体健康（即肥胖和心血管风险）和心理健康结果（即抑郁和药物滥用）密切相关，表面上是通过致胖的健康行为（即睡眠不佳和久坐行为）和社会/情感风险因素（即行为问题）。移动技术的进步增加了幼儿（6 岁以下）使用屏幕的机会，幼儿期养成的屏幕时间习惯可以持续到学龄期直至成年。对屏幕时间使用的研究受到方法学限制的阻碍，包括对回顾性自我报告措施的依赖（这些措施容易受到回忆和期望偏差的影响）。此外，对特定情况下影响屏幕时间的日内随时间变化的环境（即儿童行为、养育压力）的研究有限，对屏幕时间与行为健康结果之间联系的潜在机制的了解还不够完善。利用移动设备已经收集的数据可能会提供更客观、更细致的屏幕时间测量。整合从多个来源（即被动移动屏幕时间感知、生态瞬时评估 (EMA) 和加速测量）收集的密集纵向数据可以揭示屏幕时间与身体健康行为（即睡眠和活动）之间关联的面向过程的科学，以及心理健康（即行为问题）。本研究旨在测试在低收入家庭的看护者及其 3-5 岁孩子 30 天内被动收集客观移动屏幕时间数据并结合加速测量和 EMA 的可行性/可接受性和实用性。照顾者将完成 EMA 以评估屏幕时间背景，包括儿童行为问题（即顺从、发脾气）和父母压力。被动屏幕时间传感的有效性将使用家长 EMA 的屏幕时间报告和通过加速度测量的久坐行为进行评估。将通过分别检查是否遵守被动传感协议和定性访谈的预测因素来评估可行性和可接受性。结果将为后续强有力的试验的测量和干预策略提供信息，以确定行为干预的个性化目标，以预防肥胖和减少健康差异。该项目与 COBRE 福祉研究中心的主题完美结合，双重解决儿童的健康和社会情感行为问题。
