A novel experimental vignette methodology: SMART vignettes.

ABSTRACT: We motivate and present the methodology of vignette studies. The primary contribution of this paper is our proposal of a novel vignette study design: "SMART vignettes." Our design has two notable features: the first is its use of sequential randomization, which conceptually originates from the sequential multiple assignment randomization trial (SMART) design developed by Murphy (2004). The second feature is adaptive allocation. These new features in vignette studies offer unique advantages not offered by traditional vignettes: (1) valid causal inferences on the conditional distributions of the primary outcome of interest, given other factors, (2) balanced allocations across groups, and (3) a greater degree of interactivity for the survey respondent. We illustrate the utility of our method
