The Question of Duration and Differential Susceptibility


New working paper in progress


The conventional way to think about heterogeneity in responses to a social environmental exposure is if a response exists, and if so, how big is that response. Thus, it is variation in the magnitude (discrete or continuous) in a given response that is understood as the expression of heterogeneity. In this study we extend this conventinal approach by examining the benefits of including duration in the expression of heterogeneity.


"Building on recent advances in studies of differential susceptibility and treatment effects, we call attention to the fact that it is not only different treatments that evoke variation in treatment-response patterns, but also likely differences in the environmental cascades of social exposures experienced in the population."

With this new working paper in progress we aim to illustrate the importance of a new approach that includes duration in the estimation of heterogeneity by 1) showing how response magnitude and duration are theoretically linked, and 2) applying our theoretical model to the case of family environment circumstances and the effects on children’s behavioral problems.
