A three-level growth-curve model was applied to estimate perceived impact growth trajectories, using multi-year data from project and school surveys on outcome and program implementation collected from 59 sites and approximately 1165 participating schools in the Safe Schools and Healthy Students Initiative. Primary interest is to determine whether and how project-level and school-level correlates affect schools' perceptions of the Initiative's effectiveness over time when the effects of the pre-grant environmental conditions, grant operations, and near-term outcomes are considered. Coordination and service integration, comprehensive programs and activities for early childhood development, and change in school involvement were found to be significant predictors of school-perceived overall impact when the effect of poverty was considered. Partnership functioning, perceived importance of school resources, and school involvement were found to be significant predictors of school-perceived impact on substance use prevention when the effect of poverty was considered.
应用三级增长曲线模型来估计感知影响的增长轨迹，使用来自“安全学校与健康学生倡议”中59个地点和大约1165所参与学校的项目和学校调查的多年数据，这些数据涉及成果和项目实施情况。主要兴趣在于确定在考虑拨款前环境条件、拨款运作和近期成果的影响时，项目层面和学校层面的相关因素是否以及如何随着时间影响学校对该倡议有效性的看法。当考虑贫困影响时，协调与服务整合、幼儿发展综合项目和活动以及学校参与度的变化被发现是学校感知的总体影响的重要预测因素。当考虑贫困影响时，伙伴关系运作、对学校资源重要性的感知以及学校参与度被发现是学校感知的对预防药物使用影响的重要预测因素。
