Methods developed for causal mediation analysis with a dichotomous outcome, applicable to case-control studies via prevalence weighting will be presented. These methods generalize traditional approaches to mediation in the social sciences by allowing for interactions and non-linear models. Methods for sensitivity analysis for unmeasured confounding and measurement error in the context of mediated effects will be described. The methodology is used to resolve a question concerning direct and indirect effects in genetic epidemiology.
