The Impact of Caregiver Distress on the Longitudinal Development of Child Acute Post-traumatic Stress Disorder Symptoms in Pediatric Injury Victims

摘要

>Objective The present study prospectively examined the development of child PTSD symptoms (PTSS) and the impact of caregiver PTSS on child PTSS following injury. >Methods One hundred and eighteen ED patients and their caregivers were interviewed in-hospital and 2- and 6-weeks posttrauma. Structural equation modeling and hierarchical linear regressions examined the development of PTSS. >Results A model combining child and caregiver 2-week PTSS into one latent family PTSS variable provided the best fit to the data. Child in-hospital avoidance symptoms predicted higher levels of 2-week family PTSS. Two-week family PTSS predicted child 6-week PTSS. Post hoc analyses revealed an interaction between in-hospital caregiver avoidance symptoms and child reexperiencing symptoms in predicting 6-week child PTSS. >Conclusions Results highlight the dynamic development of child PTSS. Different symptom clusters may be related to higher PTSS at differing times posttrauma and may inform the development of time-sensitive methods of assessment and intervention for injury victims.
