The present study prospectively examined the development of child PTSD symptoms (PTSS) and the impact of caregiver PTSS on child PTSS following injury.
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.
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.
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.
本研究前瞻性地考察了儿童创伤后应激症状(PTSS)的发展,以及受伤后照顾者 PTSS 对儿童 PTSS 的影响。
118 名 ED 患者及其照顾者在受伤后立即、2 周和 6 周进行访谈。结构方程模型和分层线性回归用于检验 PTSS 的发展。
将儿童和照顾者的 2 周 PTSS 结合到一个潜在的家庭 PTSS 变量中,该模型为数据提供了最佳拟合。儿童入院时的回避症状预测了更高水平的 2 周家庭 PTSS。2 周家庭 PTSS 预测了儿童 6 周的 PTSS。事后分析显示,入院时照顾者的回避症状和儿童再体验症状之间存在交互作用,预测了 6 周时儿童的 PTSS。
结果强调了儿童 PTSS 的动态发展。不同的症状群可能与创伤后不同时间的更高 PTSS 有关,并为创伤受害者提供了时间敏感的评估和干预方法的发展提供了信息。
