基于证据的政策制定正在成为常态，但我们如何获取证据来为政策提供信息？Basu等人（Am J epidemiology . 2016;183(6): 531-538）在本期《the journal》上发表的文章中，使用了差异中的差异模型和综合控制方法来研究1996年福利改革对单身母亲健康结果的影响。在本评论中，我们讨论了政策评估观察性研究的局限性。来自经济学领域的“差中差”模型提供了一种应对这些限制的严格方法。
Evidence-based policymaking is becoming the norm, but how do we acquire the evidence to inform policies? In their article in the present issue of theJournal, Basu et al. (Am J Epidemiol. 2016;183(6):531–538) used difference-in-difference-in-differences models and a synthetic control approach to examine the effects of the 1996 welfare reforms on health outcomes among single mothers. In the present commentary, we discuss the limitations of observational studies for policy evaluation. Difference-in-differences models, from the field of economics, offer a rigorous approach to cope with those limitations.
