Objectives: Posttraumatic stress disorder (PTSD) in children is prevalent and often persists for many years after the trauma. Therefore, screening and early detection using psychometrically sound instruments is a pivotal element of appropriate management. This study tested the reliability and validity of a Korean version of the Child Reaction to Traumatic Events Scale-Revised (K-CRTES-R) in a sample of recently traumatized school children.
Methods: The K-CRTES was administered to a total of 464 school children aged ten to twelve who had witnessed or had been confronted with a tragic accident involving three deaths. Internal consistency, two week test-retest reliability, and construct validity were assessed. A non-random portion of participants also completed the State Anxiety Inventory and the Subjective Unit of Distress Scale for testing convergent validity. Exploratory factor analysis was conducted for a random half of participants (n=232), and, for the remaining half, we tested the model fit by performance of confirmatory factor analysis.
Results: Two week test-retest reliability was high (r=0.85), and internal consistency was excellent (Cronbach alpha=0.92). The total score for the K-CRTES-R showed significant correlation with state anxiety and subjective level of anxiety, thus confirming its convergent validity. In addition, the K-CRTES-R distinguished between direct exposure and indirect confrontation, demonstrating the discriminant validity of the scale. In addition, we confirmed the factorial validity by identifying a two-factor structure (intrusion-hyperarousal and avoidance) that explained 56% of the total variance. This two factor solution and other previously suggested PTSD models showed fit indices that were within an acceptable range.
Conclusion: Findings of our study indicate that the K-CRTES-R is a good measure of reliability and validity that can be used to assess the impact of trauma in Korean speaking children.
