Post-Traumatic Stress Disorder among Children Involved in Traffic Accidents and Their Parents in Japan

Children who survive traffic accidents, and their parents, may develop post-traumatic stress disorder (PTSD) or related symptoms (depression or anxiety), which can hinder the children's development and the parents' ability to provide effective care. In Japan, the PTSD incidence rate after traffic accidents and its related factors remain unclarified.

The participants were 79 children and 104 parents. The children were aged 3-18 years when injured. From August through December 2015, participants completed a self-reported questionnaire survey that comprised the 15-item Post-traumatic Stress Symptoms for Children and the Japanese version of the Impact of Event Scale-Revised. The children's Injury Severity Score (ISS) was also obtained from their medical records. Correlation analysis, analysis of variance, and multiple regression analysis were conducted.

Among the children and parents, 10.1% and 22.1%, respectively, were deemed to be at high risk of PTSD. Their stress scores were significantly positively correlated with each other and negatively correlated with the children's age at the time of the accident. Parents who witnessed their children's accidents and those whose children were hospitalized were more stressed. Neither the children's nor the parents' risk for PTSD was associated with ISS or the amount of time since the accident.

A system that simultaneously works with children and parents to support both parties' psychological recovery is required. To ensure psychological care post-injury, it is necessary to evaluate PTSD risk, regardless of injury severity. Implementing preventive and early interventions can prove more valuable than awaiting natural recovery.
