A significant minority of children and adolescents experience symptoms of acute stress following exposure to a traumatic event, some of whom will meet criteria for Acute Stress Disorder (ASD) within the first month post-trauma. Current estimates of ASD prevalence vary greatly. In order to reach a more reliable estimate, a meta-analysis of ASD prevalence was conducted which comprised of 17 studies. The impact of moderators, including trauma type and method by which ASD was assessed, provided significant. Results are discussed within the context of the relatively small number of studies that met inclusion criteria, high levels of heterogeneity, and risk of bias. Many children and adolescents who have ASD will experience a period of natural recovery in the months that follow. However, previous research has identified that for a minority of youth, ASD symptoms will remain persistent beyond the first month; meeting criteria for Post-Traumatic Stress Disorder (PTSD). The trajectory to either recovery or PTSD in youth who met criteria for ASD was explored, based upon their initial symptom profile. Of youth who met full ASD criteria, sleeping difficulties in the acute phase were associated with later PTSD. However, when using subthreshold ASD criteria, two additional symptoms showed an association. These findings are discussed with relation to the screening and assessment of children and adolescents, as well as early selective interventions, following exposure to a traumatic event.
