Differential psychological reactions to grief: The role of childhood adversity for depression symptoms among bereaved and non-bereaved adults.

Childhood maltreatment dysregulates an individual's physiological response to stress, increasing reactivity to stressors across the lifespan. Given the prevalence and impact of bereavement, we examined whether the association between childhood maltreatment and depression was exacerbated by spousal bereavement. We identified an interaction between childhood maltreatment and bereavement using linear regression analysis (B = 0.79, p < .001). A simple slopes test indicated a positive association between childhood maltreatment and depressive symptoms among those who were bereaved (B = 0.86, p < .001), but such association did not emerge among those who were not bereaved (B = 0.06, p = .60).
