This letter is a response to commentary by Skinner et al. on an evaluation by Burke et al. of the HealthMPowers program, an elementary-school-based program developed to improve child health and wellness. In their commentary, Skinner et al. make the criticism that our results for changes in BMI-for-Age Z score were simply reflective of Regression to the Mean (RTM). In this response, we show that while some of our results are consistent with RTM, with adjustment we do still observe some small effects in BMI-for-Age Z score over the course of the school year. We conclude that while our evaluation was not definitive, we still believe that programs of similar design to HealthMPowers merit further rigorous study.
这封信是对斯金纳等人就伯克等人对“健康动力”项目评估的评论的回应。“健康动力”项目是一个以小学为基础开展的项目，旨在改善儿童的健康状况。在他们的评论中，斯金纳等人批评我们关于年龄别BMI Z评分变化的结果仅仅反映了均值回归（RTM）。在本回应中，我们表明，虽然我们的一些结果与均值回归一致，但经过调整后，我们在本学年期间仍观察到年龄别BMI Z评分有一些小的变化。我们得出结论，虽然我们的评估并非决定性的，但我们仍然认为，与“健康动力”项目设计类似的项目值得进一步进行严格研究。
