The physical health costs of positive adaptation to childhood adversity.

Theories of allostatic load suggest that recurrent adaptive adjustments in contexts of adversity may have a negative impact on physical well-being. To test this hypothesis, this study evaluated 6-year-old children's ego-resilience and physical abuse experiences on behavior problems and physical illness at the age of 8 years. A significant interaction between ego-resilience and physical abuse exposure indicated that, although ego-resilience buffered physically abused children from internalizing problems, it also predicted more physical illness in that group. Findings contribute to the growing body of evidence suggesting that efforts to mobilize an adaptive response in contexts of adversity may exact a cost on physical well-being.
