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.
