417 Adolescents who've been traumatized frequently act out in violent or aggressive ways. Labeling troubled youth as either "bad" or "mad" too often overlooks the unmourned losses in their lives and the anesthetizing pull of violence. Participants in this workshop will learn about a treatment model that emphasizes working with rage, counteracting devaluation, and rehumanizing loss. The presenter will demonstrate how to use the Loss Diagram to identify the tangible and intangible losses teen clients have experienced, to help them begin to mourn those losses. We'll discuss the therapeutic qualities necessary in a clinician to be able to accept and validate clients whose behavior seems intolerable, in order to develop therapeutic relationships that can reclaim lost kids. We'll pay special attention to the needs of teenagers in juvenile detention, residential treatment, and foster care.
