Abstract

Advances in quantitative research methods have led to acceptance that well-designed observational studies can enable causal inferences about the effects of policy interventions on health. Indeed, JAMA recently announced exploring a range of study designs for which causal interpretations may be made in JAMA Network journals. This development is welcome for research on the potential health effects of laws—including statutes, regulations, executive orders, formal agency guidance, and other documents that purport to require compliance with rules or standards—given that they are rarely amenable to evaluation using experimental methods. As researchers, reviewers, and editors refine criteria for assessing the appropriateness of causal claims in health policy evaluation research, this Viewpoint emphasizes a critical methodological concern: the proper measurement of law.
