Trauma-Informed Stabilization Treatment (TIST): Effective Therapy for Complex Trauma, Dissociation, and Borderline Personality Disorder

Are you struggling with overwhelming emotions, self-destructive behaviors, or feeling disconnected from yourself? If traditional therapy hasn't provided lasting relief, Trauma-Informed Stabilization Treatment (TIST) may be the specialized trauma therapy approach you've been searching for. This evidence-based treatment offers hope for individuals experiencing complex trauma, PTSD, dissociative disorders, and borderline personality disorder (BPD) who have felt stuck despite previous therapeutic attempts.

What is Trauma-Informed Stabilization Treatment (TIST)?

Trauma-Informed Stabilization Treatment is an innovative therapeutic approach developed by Dr. Janina Fisher specifically for individuals with complex PTSD, dissociative symptoms, and chronic self-destructive behaviors including self-harm, suicidality, eating disorders, and addictions. Unlike traditional trauma therapies that focus immediately on processing traumatic memories, TIST prioritizes stabilization first—recognizing that many trauma survivors are too dysregulated to safely engage with trauma processing.​​

TIST was originally created for clients who had been hospitalized for years with treatment-resistant symptoms that hadn't responded to conventional approaches like Dialectical Behavior Therapy (DBT) or Cognitive Behavioral Therapy (CBT). These individuals had often been labeled "manipulative" or "attention-seeking," when their behaviors were actually desperate attempts to regulate an overwhelmed nervous system.​

Understanding Complex Trauma and Structural Dissociation

The Science Behind Trauma and Parts

At the foundation of TIST lies the concept of structural dissociation—the understanding that trauma causes the personality to fragment into distinct "parts" or self-states as a survival strategy. This isn't a sign of being "broken" or "crazy"; it's how the brain protects itself from overwhelming experiences, particularly childhood trauma and developmental trauma.​​

Neuroscience research shows that our brain consists of two hemispheres that process information differently. The left hemisphere, what Dr. Fisher calls the "Going On with Normal Life" part, handles daily functioning, rational thinking, and problem-solving. The right hemisphere contains the "Traumatized Parts" that hold emotional memories, survival responses, and the body's reactions to perceived danger.​

When someone experiences prolonged trauma—such as child abuse, neglect, domestic violence, or complex PTSD—the brain develops separate parts driven by different animal defense responses:​

• Fight Part: Manifests as anger, self-harm, oppositional behavior, or aggressive impulses

• Flight Part: Shows up as avoidance, addiction, dissociation, or constant busyness

• Freeze Part: Experiences terror, immobilization, shutdown, or numbness

• Submit Part: Carries shame, collapse, depression, or compliance

• Attachment/Cry for Help Part: Desperately seeks connection, reassurance, or rescue​

These aren't deliberate choices—they're automatic survival strategies that develop when a person faces overwhelming threat with no escape.​​

How TIST Works: Core Principles and Therapeutic Approach

The Language of Parts: A Neurobiological Foundation

The cornerstone of TIST is learning to recognize distressing thoughts, feelings, and impulses as communications from traumatized parts, rather than identifying with them as "me". This fundamental shift has profound neurobiological implications for trauma recovery.​

Parts Language as Stabilization

TIST therapists become "simultaneous translators," consistently reframing client experiences:​

• "I feel suicidal" becomes "A part of you feels suicidal"

• "I want to cut" becomes "The fight part wants to hurt the body"

• "I'm worthless" becomes "A young part feels worthless"

This isn't just semantics—it's neurobiologically crucial for emotional regulation. When clients say "I feel hopeless," they blend with the hopeless part, activating shame and overwhelm. When they say "A young part feels hopeless," the prefrontal cortex stays online, allowing for curiosity, compassion, and choice.​

Unblending: Creating Mindful Distance

"Unblending" means learning to notice parts without drowning in their emotions. This mindfulness-based technique helps clients develop dual awareness—the capacity to simultaneously experience a part's distress while remaining grounded in the present.​

A client might observe: "I can feel the terrified part's fear in my chest, and I can also feel my feet on the ground and my adult self here noticing her." This dual awareness is where healing happens.​

The TIST Treatment Process: Phases of Healing

Phase 1: Psychoeducation and Recognition

Treatment begins with comprehensive psychoeducation about the structural dissociation model. Rather than feeling "broken," clients often experience profound relief when their symptoms are explained as normal adaptations to abnormal circumstances.​​

Clients learn to recognize signs of parts:​

• Sudden mood shifts or personality changes

• Internal conflicts and contradictory impulses

• Overwhelming emotions that seem to come from nowhere

• Self-destructive urges or addictive behaviors

• Difficulty making decisions or maintaining consistency

Phase 2: Strengthening the "Going On with Normal Life" Self

TIST focuses on strengthening what Dr. Fisher calls the "Normal Life Self"—the part capable of functioning, working, parenting, and navigating daily life. This adult self possesses qualities essential for healing:​

• Curiosity about internal experiences

• Compassion toward wounded parts

• Clarity in understanding triggers and patterns

• Calm in the face of distress

• Creativity in problem-solving

• Courage to approach difficult emotions

• Connection to self and others

Therapists consistently acknowledge clients' strengths—their job skills, their ability to care for others, their survival against all odds. This strengths-based approach counters the shame and self-criticism common in complex trauma survivors.​

Phase 3: Developing Internal Communication

Clients learn to "ask inside"—directly communicating with their parts to understand their fears, needs, and protective intentions. A TIST therapist might guide:​

"Ask the fight part what it's worried about if you're curious about the sad part. What's the harm if you comfort the sad one?"​

Parts almost always answer, revealing their protective motives: "I'm afraid you'll be devastated again," or "I don't trust you to handle your emotions". This internal dialogue transforms parts from enemies into allies.​

Phase 4: Cultivating Internal Compassion and Collaboration

The transformative core of TIST involves fostering compassion between the adult self and young traumatized parts. When asked to "have compassion for yourself," most trauma survivors recoil. But when shown an image of a terrified five-year-old holding those same feelings, empathy naturally arises.​

Therapists guide clients to provide what Dr. Fisher calls "contradictory experiences"—the safety, comfort, and acceptance these parts never received:​

"Feel what it's like to have this little boy in your arms... Ask him if he would feel less scared if you did this every time he got afraid"​

These imaginal experiences create the same neurobiological changes as actual safe attachment, building earned secure attachment with oneself.​

TIST's Approach to Self-Harm, Suicidality, and Dangerous Behaviors

Reframing Self-Destructive Behavior

TIST fundamentally reframes self-harm, suicidal ideation, and dangerous behaviors not as pathology but as desperate survival strategies. Understanding the function of these behaviors is crucial:​​

• Self-injury stimulates adrenaline and endorphins, providing instant relief from unbearable emotions​

• Addictions regulate an overwhelmed nervous system and provide predictable comfort​

• Suicidal impulses often represent a fight part's attempt to control vulnerability: "They can't hurt you if you're dead"​

• Eating disorders create a sense of control when everything else feels chaotic​

• 
  

Working with Parts, Not Against Them

Rather than demanding abstinence or creating safety contracts (which often fail), TIST asks with genuine curiosity:​

"Which part wants to die? What is it trying to protect you from?"​

This curiosity-driven approach:

• Reduces shame and defensiveness

• Engages the prefrontal cortex

• Helps clients understand the protective—if misguided—intentions behind their most frightening impulses​

When a hospitalized client asked her suicidal part what it feared would happen if it stopped trying to kill her, the answer was revelatory: "It's the only way to push people away—they can't hurt you if they can't get close". Understanding this allowed her to address the underlying fear of intimacy rather than simply battling suicidal urges.​

The Neuroscience Behind TIST: Why It Works

Prefrontal Cortex Activation

Curiosity and mindfulness keep the thinking brain online, countering the autonomic dysregulation that shuts it down during triggering. The language of parts activates regions of the brain responsible for executive functioning, emotion regulation, and self-awareness.​

Nervous System Regulation

Co-regulation with an attuned therapist helps clients expand their "window of tolerance"—the zone where they can feel emotions without being overwhelmed or numb. This is particularly important for individuals with BPD or C-PTSD who have narrow windows of tolerance.​​

Memory Reconsolidation

Rather than just retelling traumatic stories, TIST provides corrective emotional experiences that actually update implicit trauma memories stored in the body and right hemisphere. This aligns with recent research on memory reconsolidation in trauma treatment.​​

Earned Secure Attachment

By forming loving bonds with their own wounded selves, clients develop the internal secure base they never had in childhood, fundamentally changing their relationship to themselves and others. This addresses the traumatic attachment patterns common in complex trauma survivors.​​

TIST vs. Other Trauma Therapies: Key Differences

TIST and DBT for Borderline Personality Disorder

While DBT is the most researched treatment for BPD, it requires an active prefrontal cortex to learn and apply skills. When trauma survivors are triggered, their prefrontal cortex shuts down, making DBT skills inaccessible. TIST addresses this by:​​

• Focusing on nervous system regulation before skill-building

• Using parts language to keep the prefrontal cortex online during distress

• Working with protective parts rather than trying to override them​

Many clinicians integrate TIST with DBT, using TIST for stabilization and DBT for skills training.​

TIST and EMDR

EMDR (Eye Movement Desensitization and Reprocessing) is effective for single-incident trauma but can be destabilizing for individuals with complex trauma or dissociative disorders. TIST serves as essential preparation for EMDR:​​

• Establishing internal communication before trauma processing

• Teaching unblending and grounding techniques

• Building trust with protective parts who may sabotage EMDR​

The Fragmented Selves Protocol integrates TIST with EMDR for safe trauma processing with dissociative clients.​

TIST and Internal Family Systems (IFS)

Both TIST and IFS work with parts, but TIST was specifically designed for severely dysregulated, high-risk clients with chronic self-destructive behavior. TIST:​​

• Uses more directive, trauma-informed techniques

• Focuses explicitly on nervous system stabilization

• Addresses suicidality and self-harm as primary treatment targets

• Integrates somatic and neurobiological interventions​

TIST and Schema Therapy for DID

Schema Therapy for Dissociative Identity Disorder reformulates identity states as schema modes. TIST complements this by:​

• Providing accessible language (parts vs. schema modes)

• Emphasizing internal collaboration over integration

• Focusing on day-to-day stabilization alongside deeper processing​​

  
  

What to Expect in TIST Therapy Sessions

Individual Therapy Focus

TIST is typically delivered in individual therapy sessions where your therapist will:​

• Help you identify and name your parts

• Teach you to recognize blending and practice unblending

• Guide internal dialogue between your adult self and young parts

• Address crises through parts-based interventions

• Build your capacity for self-compassion and internal collaboration

Session Structure and Frequency

TIST sessions typically occur weekly or more frequently for high-risk clients. Each session focuses on:​

• Current triggers and challenges

• Recognizing which parts are activated

• Developing internal communication and negotiation

• Building skills for nervous system regulation

• Creating safety plans through internal collaboration​

Timeline for Treatment

TIST is not a quick fix—healing complex trauma takes time. Most clients engage in TIST for:​

• 6-12 months for stabilization phase

• 1-3 years for deeper trauma processing

• Ongoing maintenance as needed for complex cases​​

The timeline depends on trauma severity, dissociative symptoms, and co-occurring conditions like BPD or addiction.​​

Self-Care and TIST: Supporting Your Healing Journey

Between-Session Practices

TIST encourages self-care practices that support nervous system regulation:​

• Mindfulness and grounding techniques to stay present

• Journaling to track parts and internal dialogue

• Somatic practices like yoga, breathing exercises, or gentle movement

• Sleep hygiene and nutrition for nervous system health​

Building Your Support System

While TIST focuses on developing your internal support system, external support remains important:​

• Support groups for trauma survivors, BPD, or specific issues

• Safe relationships with people who respect your boundaries

• Crisis resources like helplines or emergency contacts

• Psychiatric support if medication helps manage symptoms​

  
  

The Healing Promise of Trauma-Informed Stabilization Treatment

From Fragmentation to Integration

What makes TIST distinctive is its fundamental premise: you are not broken, you are fragmented. The parts that seem to sabotage your life are actually trying to keep you safe using strategies that once worked but no longer serve you.​​

Healing doesn't require eliminating these parts—it requires welcoming them home, listening to their wisdom, and helping them update their understanding of safety.​

Transformation Through Compassion

As clients learn to relate to their parts with curiosity rather than contempt, profound transformation occurs:​

• Self-hatred transforms into self-compassion

• Internal warfare gives way to internal collaboration

• Terrorized child parts, feeling finally heard and protected, begin to settle

• Clients discover what was there all along beneath the chaos: a life worth living, a self worth knowing, and a future no longer held hostage by the past​​

Hope for Treatment-Resistant Cases

For individuals who have cycled through multiple therapies, hospitalizations, and treatment programs without sustained improvement, TIST offers genuine hope. It was specifically designed for those labeled "treatment-resistant," recognizing that they weren't failing therapy—therapy was failing them by not addressing the fragmented nature of their experience.​​
