Complex trauma in children and adolescents: evidence-based practice in clinical settings.

Complex trauma (CT) results from exposure to severe stressors that occur within the caregiver system or with another presumably responsible adult, are repetitive, and begin in childhood or adolescence. As a result, many of these children and adolescents experience lifelong difficulties related to self-regulation, relationships, psychological symptoms, alterations in attention and consciousness, self-injury, identity, and cognitive distortions. The aims of this article include the following: (a) to examine several representative approaches identified as treatments for children and adolescents exposed to CT with respect to similarities and differences; (b) to examine representative evidence of model effectiveness; (c) to discuss how these approaches are and/or could be implemented in clinical practice; and (d) to suggest research designs that would facilitate greater translation of effective treatment into clinical settings.
