DESCRIPTION (provided by applicant): The proposed study will evaluate the reliability and validity of a calibrated self-report instrument called the Youth Activity Profile (YAP) for assessig youth physical activity (PA) and sedentary behavior (SB). Considerable work has been done to improve objective monitoring techniques but the systematic use of calibration procedures provides a way to improve the utility of self- report instruments for research and public health surveillance. With appropriate calibration, it is possible to convert self-reported PA and SB data into estimates that correspond to more accurate values obtained using objective measures. This would make it possible to obtain accurate, group level estimates of PA and SB using less expensive feasible methods. Preliminary calibration of the YAP demonstrates that it can produce accurate group estimates of PA and predict compliance with established public health guidelines for PA. The proposed study will build on this work by calibrating and evaluating web-based versions of the YAP that will enable broader adoption in school based programming and youth research. The 3 independent aims will allow us to continue our systematic refinements of this promising public health tool. In Aim 1 we will determine the reliability and equivalence of th three different versions of the YAP (Print, Online, and Online Game). We will administer the 3 different versions to intact classrooms from 12 different schools (36 classrooms total) on two occasions (1-2 weeks apart) to examine the test-retest reliability and equivalence of the alternative formats. In Aim 2 we will develop and test new calibration algorithms for use with the web-based versions of the YAP. Data will be collected with the online version (using our established protocol) in two regionally distinct metropolitan school systems (Des Moines and Dallas) across a full academic school year to increase the generalizability of the algorithms. In Aim 3 we will test the validity and equivalence of the web-based versions of the YAP through a large participatory research network involving over 1000 schools (NFL PLAY 60 FITNESSGRAM(R) Partnership Project). Construct validity will be evaluated for both the Online and Online Game versions by examining correlations with group level estimates of physical fitness from the FITNESSGRAM battery. Age and gender patterns of PA from the Online and Online Game versions will be evaluated for equivalence and, if necessary, output from the Game version will be standardized using a test- equating step. The proposed study will systematically evaluate the utility of the web-based formats of the YAP for school-based research on PA and SB. With additional refinement, these tools can facilitate the systematic evaluation of youth PA and SB patterns across the country.

描述（由申请人提供）：拟议的研究将评估评估青年体育活动（PA）和久坐行为（SB）的校准自我报告仪器的可靠性和有效性。已经为改善客观监测技术做出了大量工作，但是校准程序的系统使用提供了一种改善自我报告工具进行研究和公共卫生监视的效用的方法。通过适当的校准，可以将自我报告的PA和SB数据转换为对应于使用客观度量获得的更准确值的估计值。这将使使用较便宜的可行方法获得准确的PA和SB的小组级估计。 YAP的初步校准表明，它可以产生PA的准确组估计，并预测符合已建立的PA的公共卫生指南。拟议的研究将通过校准和评估基于Web的YAP版本来基于这项工作，这将使基于学校的编程和青年研究更广泛地采用。这3个独立目标将使我们能够继续对该有前途的公共卫生工具进行系统的改进。在AIM 1中，我们将确定三种不同版本的YAP（印刷，在线和在线游戏）的可靠性和等效性。我们将在两次（相隔1-2周）的12个不​​同学校（总共36个教室）的完整教室管理3个不同版本，以检查替代格式的重测可靠性和等效性。在AIM 2中，我们将开发和测试新的校准算法，以与YAP的基于Web的版本一起使用。在整个学年的两个区域大都市学校系统（得梅因和达拉斯）中，将使用在线版本（使用我们既定的协议）收集数据，以提高算法的普遍性。在AIM 3中，我们将通过大型参与性研究网络（NFL Play 60 Fitnessgram（R）合作伙伴关系项目）测试YAP基于Web的版本的有效性和等效性。通过检查与Fitnessgram电池的身体适应性估算的相关性，将对在线和在线游戏版进行构造有效性。将评估来自在线和在线游戏版本的PA的年龄和性别模式的等效性，并在必要时使用游戏版本的输出进行标准化。拟议的研究将系统地评估基于YAP的基于网络的YAP的实用性，用于对PA和SB的学校研究。通过额外的完善，这些工具可以促进全国青年PA和SB模式的系统评估。
