Trauma-Informed Stabilization Treatment (TIST) is an integrative approach that combines Internal Family Systems (IFS), somatic therapy, and Polyvagal Theory to help clients with complex trauma recognize their distressing thoughts, feelings, and impulses as protective parts rather than identifying with them. This method helps clients shift from saying 'I want to die' to 'there's a part of me that wants to die,' which reduces shame and intensity. The approach emphasizes that trauma survivors need to be seen, witnessed, and co-regulated by therapists, as the social engagement system is crucial for healing. TIST works with clients who have no memory of their trauma as well as those with clear event memories, focusing on the effects of trauma (not being seen, heard, or recognized) rather than just the events themselves.
