Next, race, between- and within-person daily family stressors, and the interactions between daily family stressors and race were entered as predictors of daily affect and physical symptoms. We estimated separate models for each outcome: daily NA (Model 1), daily PA (Model 2), and Symptoms (Model 3). In addition to concurrent stressor effects, we also included lagged family stressor effects in the same models in order to examine whether the effects of family stressors on daily affect and physical symptoms endures on subsequent days (Caspi et al., 1987). We also included the interactions between race and the lagged family stressor effects to explore whether the lagged effects varied by race. Finally, the level of the dependent variable from the previous day was also included as a control so that the lagged family stressor effects were adjusted for any influence of NA, PA or symptoms from the previous day to assess how prior day family stressors predict a change in the affect (symptoms) from one day to the next.
