Pathways was a large-scale, multisite, 3-year, study testing a school-based intervention designed to lower percent body fat in American Indian children.
At the 21 intervention schools process evaluation data were collected for training of school personnel; implementation of the classroom and physical activity curricula; implementation of the project's food service guidelines in the school cafeterias; adult participation in the family events; and, students' perceived exposure to the Pathways interventions.
Students received about 93% of the classroom curriculum lessons. The minimum requirement of physical education being taught three times per week for at least 30 minutes duration was achieved by the fifth grade. The implementation of the food service behavioral guidelines increased from 51% in the third grade to 87% in the fifth grade. The family events had lower than anticipated adult participation. The participation rates were 45% during the third grade, and 41 and 63% during the fourth and fifth grades, respectively. There was a significant difference between intervention and control students' perceived exposure to Pathways type interventions.
The Pathways interventions were successfully implemented with good reach, high extent, and fidelity.
“路径”是一项大规模、多地点、为期3年的研究,旨在测试一种以学校为基础的干预措施,以降低美国印第安儿童的体脂百分比。
在21所干预学校收集过程评估数据,内容包括学校工作人员的培训情况;课堂和体育活动课程的实施情况;学校食堂项目餐饮服务指南的实施情况;成年人参与家庭活动的情况;以及学生对“路径”干预措施的感知接触情况。
学生接受了约93%的课堂课程。到五年级时,达到了每周至少30分钟、每周授课三次的体育教育最低要求。餐饮服务行为指南的实施率从三年级的51%提高到五年级的87%。家庭活动中的成年人参与率低于预期。三年级的参与率为45%,四年级和五年级的参与率分别为41%和63%。干预组和对照组学生对“路径”类干预措施的感知接触情况存在显著差异。
“路径”干预措施得以成功实施,具有良好的覆盖面、实施程度和保真度。
