Abstract
Abstract Exposure to stressors in childhood is theorized to sensitize individuals to stressors experienced later in life. One way that stress sensitization might manifest is through greater affective reactivity to daily stressors. In turn, greater affective reactivity to daily stressors has been associated with poorer health and increased mortality risk. The present pre-registered investigation tested greater affective reactivity to daily stressors in later life as a potential mediator of the association between early life stressors and mortality risk in a sample of 144 men from the VA Normative Aging Study. Partially consistent with our hypotheses, greater early life psychosocial stressors were associated with greater positive (but not negative) affective reactivity to daily stressors in later life. However, neither early life psychosocial stressors nor affective reactivity to daily stressors were significant predictors of mortality risk. We will discuss implications of these findings for theories of stress experience across the lifespan.
