Sociocontextual circumstances in daily stress reactivity among caregivers for elder relatives.

Using a daily diary design, we examined whether emotional and physical reactivity in the face of care-related stressors is more intense for caregivers (CGs) living with lower levels of available socioemotional support and higher numbers of extrinsic stressors. Sixty-three CGs reported their experiences based on the past 24 hr (i.e., number of caregiving tasks, care recipient problem behaviors, family disagreements regarding care, depressive symptoms, feelings of burden, physical symptoms) on eight consecutive survey days; they also reported on extrinsic stressors and available socioemotional support. Multilevel analyses indicated significant moderator effects: within-person patterns of reactivity to care-related stressors were especially strong for CGs with lower levels of available socioemotional support and higher numbers of extrinsic stressors. For example, managing additional care recipient problem behaviors on a given day was more strongly associated with increased depressive and physical health symptoms as well as feelings of burden for CGs with relatively high numbers of extrinsic stressors. Implications for intervention are discussed.
