Incidence in children and adolescents

What is incidence of PTSD in children and adolescents?

It is different from prevalence, which represents how many overall cases exist. This topic presents the evidence on incidence rates in children and adolescents.

Moderate quality evidence finds the incidence of PTSD in children and adolescents is around 16% at least one month after exposure to trauma. The incidence rate is highest in females, and in children and adolescents exposed to interpersonal rather than non-interpersonal trauma.
