title: Physiological responses to non-child-related stressors in mothers at risk for child abuse.
abstract: Physical child abusers and adults at risk for child abuse, relative to comparison subjects, are reported to be more physiologically reactive to child-related stressors. It is not known if the reported physiological reactivity is child specific or if physical child abusers and at-risk parents are also more reactive to other types of stressful stimuli. The present study investigated changes in heart rate and skin conductance in response to four types of non-child-related stressors in at-risk and matched low-risk mothers. The four types of stressful stimuli were: a cold pressor; a stressful film depicting industrial accidents; unsolvable anagrams; and an aversive car horn. At-risk mothers, relative to low-risk mothers, had greater and more prolonged sympathetic activation during presentations of the cold pressor and the stressful film, the stimuli rated as the most stressful. The present data, combined with previous findings, support the view that generalized sympathetic activation to both child and non-child-related stressors may serve as a mediator of physical child abuse.
