ABSTRACT
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. We recruited children (N=43, age 9 years at initial visit) for a longitudinal study in which SCR was recorded at baseline visit, and PTSD symptoms were assessed two years later. Results indicated an interaction between SCR and trauma exposure, such that children with lower trauma exposure who demonstrated greater SCR reported higher PTSD severity two years later. This association remained significant even after controlling for baseline PTSD symptoms. Children with higher levels of trauma exposure did not show this association, potentially due to ceiling effects of PTSD symptoms. Together these findings suggest the utility of SCR as a biomarker for predicting trauma related disorders in children, and that it may be a valuable tool in clinical interventions targeting sympathetic arousal.
