RESUMEN
OBJECTIVE: Few studies have examined hypothalamic-pituitary-adrenal axis stress reactivity and its relationship to histories of child maltreatment and physical aggression. We examined the relation of a history of childhood sexual abuse (CSA) and perpetration of dating violence to patterns of cortisol change before (resting) and after (reactivity) exposure to a laboratory stressor. METHODS: In a sample of 40 disadvantaged sexually active female adolescent patients (ages 14-17 years), we collected self-reports of lifetime child maltreatment (5 types) and past-year female perpetration of physical assault (PA) acts toward a romantic partner. We assessed changes in salivary cortisol trajectories during resting and reactivity phases following the viewing of a teen dating violence vignette. RESULTS: Reports of CSA (CSA+ group) were associated with reports of perpetration of severe dating PA (PA+ group), but the relation of these reports to laboratory-assessed patterns of cortisol changes following the stressor was opposite. As compared with subjects without victimization or perpetration histories (referent group), the CSA+ group showed the most pronounced positive slope (reactivity), whereas the PA+ group showed the least positive slope following the laboratory stressor after the overlap between these groups was statistically adjusted. While showing less reactivity to the laboratory stressor, the PA+ group had higher levels of resting cortisol, which stayed high during reactivity as compared to the referent group. CONCLUSION: The laboratory paradigm to elicit neuroendocrine stress-related cortisol reactivity appears to be a promising tool for identifying altered cortisol physiology among female adolescents with mixed histories of CSA and perpetration of dating PA.
