Offers guidance to help those working with youth involved in multiple systems (YIMS) and their families to use a traumatic stress perspective and provide trauma-informed care. This resource guide uses two case vignettes throughout to illustrate the concepts within. It describes what trauma and recovery might look like for YIMS, trauma-informed practices that could be beneficial, using trauma-informed screening and assessment with YIMS, engaging in trauma-infromed case planning and intervention, and managing secondary traumatic stress for providers.
