Previous cross-sectional studies have shown that sympathetic nervous system (SNS) arousal is positively associated with posttraumatic stress disorder (PTSD) symptoms in children with trauma exposure. One of the ways that SNS activity is measured is through skin conductance response (SCR), which has been shown to predict future PTSD severity in adults. In this study, we explored the utility of a novel, low-cost mobile SCR device, eSense, to predict future PTSD symptom severity in trauma exposed children.

Black Americans are disproportionately affected, as they are at increased risk for experiencing childhood trauma and cardiovascular diseases in adulthood. One of the hypothesized mechanisms of this association is through long-lasting dysregulation of the autonomic nervous system, a hallmark physiological biomarker of posttraumatic stress disorder (PTSD), which is twice as prevalent in women compared to men.

- There are differences in how different racial and ethnic groups experience stress and resources that can affect their brains, especially the amygdala, which helps process fear and trauma.
- A study with 283 participants looked at how their brains reacted to scary and neutral faces after trauma, finding that Black and Hispanic people had different brain connections compared to White people.
- The results suggest that these differences in brain activity and responses to stress may influence how likely someone is to develop PTSD after experiencing traumatic events.
Although many children experience trauma, few receive diagnoses and subsequent care despite experiencing trauma-related sequelae. At age nine (M = 9.11), children (N = 62; female = 46.
