Stress Physiology and Behavior Problems Abstract Understanding childhood externalizing problems is informative in designing interventions and reducing crime in adulthood because childhood aggression is one of the best predictors for later antisocial behavior. Childhood externalizing problems are typically studied with internalizing problems (e.g., anxiety) given their consistent correlation and seemingly opposite behavior manifestations. This dissertation examined both spectrums of behavior problems to advance our etiological understanding. Adversity and stress have been a focus in criminology research but few studies have incorporated stress physiology, the biological underpinning of how individuals deal with adversity. This dissertation comprised three papers testing the linkage of stress physiology to behavior problems. I examined how the two components of the stress system, namely the hypothalamic-pituitary-adrenal (HPA) axis and the autonomic nervous system (ANS), interact with each other, and together interact with harsh discipline in influencing externalizing and internalizing problems. Data were drawn from a community sample of 11-12 year old children (N = 446). Saliva samples were collected in the initial assessment and later assayed for cortisol (HPA) and salivary alpha-amylase (sAA; ANS).
