DESCRIPTION (provided by applicant): Physical inactivity during adolescence increases risk for a number of serious health conditions. Surveillance, epidemiological, and intervention studies seeking to increase physical activity and/or decrease sedentary behaviors in adolescents could be enhanced through more informative and accurate methods of measuring these behaviors. Concerns about the validity of retrospective self report of physical activity and sedentary behavior have led to increasing use of objective measures, e.g., accelerometers and Global Positioning System (GPS) loggers, which can be complemented by subjective or contextual information using self-initiated event-contingent electronic ecological momentary assessment (EMA) after exercise or other critical activities. Regardless of the technique used, device non-wear, equipment malfunction, and participant non-response result in missing and ambiguous data that complicate statistical analysis. Adolescents recruited into objective PA monitoring studies will increasingly have so-called "smart phones," which are miniature computers with built in motion sensors and location-finding capabilities. Sophisticated programs (i.e., "apps") can be easily installed on the phones. The overall objective of this project is to develop new software for common mobile phones that can both reduce and explain missing data collected during objective and EMA activity monitoring studies with free living adolescents. This technology will supplement objective monitors already used today, with minimal additional cost. Our solution will have three novel components: (1) A phone "app" that uses the mobile device's built-in sensors to detect major transitions in type of movement or location, after which timely, context-sensitive questions and reminders are triggered that will reduce and explain missing or incomplete activity, location, and event- contingent EMA data, regardless of whether built-in or external objective monitors are used, (2) A second phone "app" that has an entertaining, game-like feel and allows adolescents to interactively "fill in gaps" in their own data at the end of the day using cues from automatically-detected major transitions to explain this missing data, and (3) Server-side software that will remotely collect data from the two apps in real-time and provide researchers with a cost-efficient way to reduce missing data and improve characterization of transition in activity. The system's feasibility, acceptability, and performance will be compared to the current state of the art in a within-subjects study with a free-living sample 40 low-to-middle income, ethnically diverse adolescents in 9-12th grade. The source code for all the software will be made freely available to other researchers.

描述（由申请人提供）：青春期缺乏身体活动会增加一些严重健康状况的风险。通过更多的信息和准确的测量这些行为的方法，可以加强监测、流行病学和干预研究，以增加青少年的身体活动和/或减少久坐行为。对身体活动和久坐行为的回顾性自我报告的有效性的关注导致越来越多地使用客观测量，例如加速度计和全球定位系统（GPS）记录器，这些测量可以在运动或其他关键活动后使用自我发起的事件电子生态瞬间评估（EMA）来补充主观或情境信息。无论采用何种技术，设备不磨损、设备故障和参与者不响应都会导致数据缺失和模糊，从而使统计分析复杂化。参与客观PA监测研究的青少年将越来越多地拥有所谓的“智能手机”，这是一种内置运动传感器和定位功能的微型电脑。复杂的程序（即“应用程序”）可以很容易地安装在手机上。该项目的总体目标是为普通手机开发新的软件，可以减少和解释在自由生活青少年的客观和EMA活动监测研究中收集的缺失数据。这项技术将以最小的额外成本补充目前已经使用的客观监测仪。我们的解决方案将有三个新颖的组成部分：(1)手机“应用程序”，使用移动设备的内置传感器来检测运动类型或位置的重大转变，之后，及时，上下文敏感的问题和提醒被触发，将减少和解释缺失或不完整的活动，位置和事件相关的EMA数据，无论是否使用内置或外部目标监视器；(2)第二个手机“应用程序”具有娱乐性，游戏般的感觉，并允许青少年在一天结束时使用自动检测到的主要转变的线索来交互式地“填补空白”自己的数据，以解释这些缺失的数据。(3)服务器端软件将远程实时收集来自两个应用程序的数据，并为研究人员提供一种经济有效的方法来减少缺失的数据，并改善活动转变的表征。该系统的可行性、可接受性和性能将在一项主题内研究中与当前最先进的技术进行比较，该研究包括40名自由生活的中低收入、不同种族的9-12年级青少年。所有软件的源代码将免费提供给其他研究人员。
