Core Tip: Prevalence rates of child and adolescent posttraumatic stress disorder (PTSD) range from 0.5%-5%, while subthreshold PTSD and other trauma-related difficulties are relatively common among trauma-exposed children. Prevalence rates of sleep disturbances among trauma-exposed child samples vary considerably. Adverse effects of childhood trauma on sleep have been found immediately as well as years after trauma and can still be demonstrated in adulthood. Several hypotheses have been proposed to explain the mechanisms by which traumatic exposure may affect sleep. We discuss here the role of sleep problems in traumatized children and adolescents, and a broad range of etiological mechanisms for these symptoms.
