This study describes the development and pilot testing of the Observational System for Recording Physical Activity-Elementary School (OSRAC-E) Version.
This system was developed to observe and document the levels and types of physical activity and physical and social contexts of physical activity in elementary school students during the school day. Interobserver agreement scores and summary data were calculated.
All categories had Kappa statistics greater than .80, with the exception of the activity initiator category. Interobserver agreement scores were 96% or greater. The OSRAC-E was shown to be a reliable observation system that allows researchers to assess physical activity behaviors, the contexts of those behaviors, and the effectiveness of physical activity interventions in the school environment.
The OSRAC-E can yield data with high interobserver reliability and provide relatively extensive contextual information about the physical activity of students in elementary schools.
本研究描述了小学生身体活动记录观察系统（OSRAC-E）版本的开发和试点测试。
开发该系统是为了观察和记录小学生在学校日的身体活动水平和类型以及身体活动的身体和社会背景。计算了观察者间一致性得分和汇总数据。
除活动发起者类别外，所有类别kappa统计量均大于0.80。观察者间一致性得分达到96%或更高。结果表明，OSRAC-E是一个可靠的观察系统，可让研究人员评估身体活动行为、这些行为的背景以及学校环境中身体活动干预措施的有效性。
OSRAC-E能够产生具有高观察者间可靠性的数据，并提供有关小学生身体活动的相对广泛的背景信息。
