Trauma treatment is rarely straightforward. Clients want help but resist connecting emotionally. Many are tormented by critical self-hating thoughts or want to die, jeopardizing their ability to process the trauma. TIST is a new trauma-informed treatment that directly addresses the challenges, not just the events, of a traumatic past. In TIST, we view these trauma-related thoughts, emotions, and impulses as communications from fragmented, disowned trauma-related parts. When clients form meaningful attachment relationships to these young, rejected parts, the trauma often resolves spontaneously. When the parts finally experience safety and care, the traumatic past feels done and behind them.
