A prospective examination of the role of childhood sexual abuse and physiological asymmetry in the development of psychopathology.
OBJECTIVE
Recent literature has emphasized the simultaneous assessment of multiple physiological stress response systems in an effort to identify biobehavioral risk factors of psychopathology in maltreated populations. The current study assessed whether an asymmetrical stress response, marked by activation in one system and a blunted response in another system, predicted higher levels of psychopathology over time.


METHODS
Data were collected from an ongoing, prospective study of females with a substantiated history of childhood sexual abuse (n=52) and a non-abused comparison group (n=77). Childhood sexual abuse was determined at the initial study visit. Vagal tone and cortisol were measured 7 years later to assess physiological response to a laboratory stressor across these systems. Depressive symptoms and antisocial behaviors were assessed 6 years after the completion of the laboratory stressor.


RESULTS
Structural equation modeling indicated that a prior history of childhood sexual abuse predicted an asymmetrical physiological response to stress in late adolescence. In turn, this asymmetrical response predicted both higher levels of depression and antisocial behaviors in young adulthood.


CONCLUSIONS
Childhood sexual abuse may sensitize females to respond to moderate daily stressors in a manner that places them at higher risk for experiencing depressive symptoms and antisocial behaviors over time.


CONCLUSIONS
The management of mild to moderate stress in the everyday lives of maltreated females may be a particularly useful point of intervention in order to protect against later psychopathology.
