Well-Beingdi is the reported well-being (i.e., daily affect, physical symptoms) on Dayd of Personi, Family Stressordi indicates whether a family stressor was experienced by Personi on Dayd, β0i is the intercept indicating Personi’s level of well-being on days when Family Stressor = 0, β1i is the change in affect or symptom reports from a non-family stressor day to a family stressor day, indicating the emotional (i.e., affect) or physical reactivity (i.e., physical symptoms) of Personi to the daily family stressor. edi is the residual variance. In order to estimate average effects for the entire sample, the intercepts and slopes of the Level 1 within-person model become the outcomes for the Level 2 between-person equations. Equations 4 and 5 model racial differences in Level 1 (Equation 3) intercepts and slopes. Of particular interest here is Equation 5 which tests whether the reactivity slopes (β1i) vary by race. δ00 and δ10 are the average within-person intercept and the daily family stressor effect (i.e., the fixed effects), and U0i is the person-specific deviations from the intercept (i.e., random effect). δ10 and δ11 are
