The WP family argument effect was significant for both African Americans (estimate = 0.64, SE = 0.17, p < .001) and European Americans (estimate = 0.11, SE = 0.05, p < .05; Table 3, Model 3). The racial difference in the WP effect was also significant (Table 3, Model 3), indicating that Africans Americans are more physically reactive to family arguments compared to European Americans. The lagged family argument effect was only significant for African Americans (estimate = 0.30, SE = 0.14, p < .05), not for European Americans (estimate = 0.04, SE = 0.05, ns), although the racial difference was not statistically significant. African Americans reported increased physical symptoms the day after they reported a family argument.
