Study Description


1003 ASC-Kids Development Study


Nancy Kassam-Adams


Exposure to traumatic events is a common experience for children and adolescents. Accurate early assessment of acute stress responses can help predict risk for longer term sequelae and can guide secondary prevention to reduce the incidence and severity of PTSD after trauma exposure. However, at the time of this study there was no established self-report measure of ASD for children and youth. The goal of this study was to develop a practical self-report measure of Acute Stress Disorder (ASD) for children and adolescents, and to provide initial evidence as to its reliability and validity.

The specific aims of the study were to: Aim 1: Establish the content validity of a pilot Child ASD measure for ages 8 to 17, based on expert review and youth feedback. Aim 2: In a sample of recently injured children, assess the psychometric properties of the measure: internal consistency, test-retest reliability, convergent and discriminant validity with other measures and other reporters. Aim 3: Provide initial data regarding the predictive validity of the Child ASD measure in relation to later PTSD development in the same sample of children.

This dataset includes data related to Aims 2 and 3.
