"Beyond Internal Validity: Field notes from the methodological borderlands"
"The effect of smoking on risk of death is not the same as the effect of a smoking cessation intervention on risk of death -- but we frequently act as if it is when considering policy. In this talk, I will describe the causal impact framework, which considers first internal validity; then external validity; then population intervention impact; and (sometimes) cost-effectiveness analysis. The causal impact framework shows one way forward to making epidemiologic findings more relevant to both public policy and implementation science, and likewise ways in which the epidemiologist can more effectively coordinate with both health behaviorists and health policy scientists."
