DESCRIPTION:

TIST psychotherapy is nothing new: it focuses on the therapeutic stabilisation of the nervous system in cases of trauma-related disorders, supplemented by trauma therapy, EMDR, IFS and Brainspotting.

TIST – Trauma-Informed Stabilisation Treatment: a form of psychotherapy designed to stabilise the nervous system and parts of the self, and to alleviate the effects of trauma

Trauma-Informed Stabilisation Treatment (TIST) is nothing new. It combines established forms of sub-personality work with insights from neurobiology and regulation to form an integrative model of modern trauma therapy.

What it’s all about:

·         the key principles, techniques and areas of application of TIST,

·         the positioning of the method within the field of stabilising psychotherapy, and

·         How fragmentation following traumatic events can be treated.

What is TIST, and why do we want to stabilise the nervous system first?

TIST stands for ‘Trauma-Informed Stabilisation Treatment’ and describes a well-known structured approach that does not first confront traumatised people with their history, but helps them to stabilise their nervous system. Underlying this is the belief that stabilisation is not a preliminary stage of ‘real’ trauma therapy, but is effective in its own right. Only when overwhelming emotions can be safely contained can distressing memories be integrated at all.

The Stabilisation Treatment approach combines information, mindfulness and a compassionate approach to inner parts. In trauma therapy, this means that rather than focusing on the ‘what’ of a traumatic history, TIST turns its attention to the here and now – to bodily sensations, impulses and automatic reactions that manifest in everyday life. In this way, those affected learn to interpret symptoms as survival strategies, rather than allowing themselves to be overwhelmed by them.

This is also the essence of the term ‘trauma-informed’: TIST is an informed, respectful approach that takes the special need for protection of traumatised people seriously. The approach is based on the well-known fact that premature exposure does not heal but can re-traumatise. That is why therapists initially invest a great deal of time in building rapport, engaging in resource-based work, and ensuring a clear structure for the sessions before distressing topics are even brought up.

Where does TIST come from, and what theories form its basis?

TIST originated in the USA from clinical work with severely traumatised people and is currently becoming popular worldwide. The developer of the method worked for decades with students of the renowned Bessel van der Kolk and Peter Levine, as well as with Ellert Nijenhuis, Onno van der Hart and Kathy Steele. The eclectic mix of claims drawing on attachment theory, neurobiology and psychotraumatology forms the ‘theoretical foundation’ of TIST.

The first description of the approach appears in ‘Healing the Fragmented Selves of Trauma Survivors’ (2017), which systematically presents the basic ideas for the first time. There is nothing new in it: for instance, how trauma survivors are often in conflict with themselves – some parts crave closeness, others flee, and still others punish. In “clinical workshops”, the proponents address therapists worldwide with the claim that only TIST enables the gentle healing of the split-off inner children. Yet the principle of “stabilisation before processing” has long been a standard component of trauma treatment guidelines.

Understanding dissociation: How do traumas fragment the personality?

Dissociation is initially a normal, adaptive reaction of the brain: it protects itself by splitting off unbearable experiences. In the case of severe or repeated childhood trauma – such as neglect, violence or sexual abuse – this dissociation can become permanent. The personality then appears fragmented: individual states maintain daily life and work, whilst others bear the burden of the traumatic experience.

Many affected individuals experience this without being able to put a name to it. They are triggered in everyday life and result in intense physical sensations, freezing, or hyperarousal. Shock traumas such as accidents or assaults can trigger similar patterns, as can developmental trauma that has gone unnoticed for a long time. The spectrum of symptoms ranges from the classic picture of PTSD to cPTSD and dissociative identity disorder (DID, formerly multiple personality disorder) with memory loss and a variety of inner voices – not a few of these consequences of trauma are misdiagnosed for years.

Trauma therapy provides an explanatory framework that helps to reduce shame. When those affected understand that their dissociation is a response of the nervous system and not a personal failure, they can view themselves with greater compassion. This attitude promotes relaxation, reduces internal conflict and creates space for further stabilisation.

What does the theory of structural dissociation by Nijenhuis, van der Hart and Steele say?

The theoretical backbone of many modern approaches – including TIST – is the theory of structural dissociation. In it, Ellert Nijenhuis, Onno van der Hart and Kathy Steele describe how, under extreme stress, the personality is structurally split into an ‘apparently normal ’ and one or more ‘emotional parts’. This fragmentation is neurologically rooted and well-documented in trauma research.

The more severe and the earlier the stress, the more “fragmented parts of the self” emerge. This perspective significantly alters both the diagnosis of dissociative disorders and the approach in therapeutic contact. TIST adopts this model: every symptom belongs to a part that was once vital for survival.

What are parts of the self, and how does TIST address them?

Self-parts – also known as ego states or ego state parts in ego state therapy – are inner states with their own voices, bodily memories, and convictions.  In TIST, too, they are understood as inner co-inhabitants seeking protection, closeness, or control. Those affected learn not to fight these parts but to enter into an inner dialogue with them.

In TIST, this is achieved through mindfulness-based exercises in which one compassionately observes tension, pain or an impulse and asks how old this part feels. Through repeated practice, moments of reparative relationship emerge – initially between the therapist and the client, then between the parts themselves.

It is important here to distinguish between “I” and “a part of me”. Anyone who says, “A part of me is afraid of the phone call”, already experiences an initial sense of relief – the fear belongs to a part, not to the whole person. This small linguistic shift is also a central tool in TIST. It creates inner distance without dissociation and enables a more loving way of dealing with one’s own feelings.

How can trauma therapy slow down the autonomic nervous system and regulate impulses?

The second pillar, alongside working with parts, is regulating the nervous system. TIST uses well-known techniques to calm the autonomic nervous system: conscious breathing, grounding exercises, imagery, deep relaxation, and brief elements of suggestion. The effect can be measured – blood pressure drops, the muscles relax, and the brain’s executive functions become accessible again.

It is equally important to stimulate the other side of the autonomic nervous system: those who live chronically in a state of paralysis or collapse need gentle activation—movement, contact, embodiment exercises—this pendulum swing between calming and activating forms the core of all self-regulation. The body thus becomes an ally rather than an enemy – a crucial step towards greater security in one’s own life.

How does TIST differ from EMDR, IFS, Somatic Experiencing, Brainspotting and ego-state therapy?

Hardly. From EMDR, the principles of bilateral stimulation and a controlled approach to traumatic material are adopted. From Richard Schwartz’s Internal Family Systems (IFS) comes the understanding that inner multiplicity is normal and treatable; the concept of the internal family system significantly influences TIST’s sub-personality work.

Further influences come from Somatic Experiencing by Peter Levine, Brainspotting by David Grand, and classical ego-state therapy. Unlike TIST, Brainspotting offers a defined physical approach to this, whilst ego-state therapy provides tools for hypnosystemic interventions. TIST merely shifts the emphasis: as with all proven methods, it requires a robust stabilisation phase, rather than forcing exposure or Brainspotting too early.

What does a session in trauma therapy actually look like?

A typical trauma therapy session begins with an assessment of the patient’s current state: what has the patient experienced since the last session? What bodily sensations, moods and conflicts have arisen? The therapeutic work then links these observations to inner parts – in a practical, jargon-free manner, and with great care for the patient’s pace.

Over the course of the process, imaginative exercises may be introduced: an inner safe place, a dialogue with a younger part of the self, or a session focused on deep relaxation. If a patient is triggered, the therapist deliberately pauses, identifies the activated part and supports the activation of resources. Over weeks and months, a new balance emerges in which triggered states become less frequent and shorter – the core of trauma therapy work.

Between sessions, clients practise applying the regulation tools they have learnt independently. Short diary entries, brief grounding exercises or connecting with a previously identified safe place help to transfer these skills into everyday life. The more reliably those affected can understand and regulate their own impulses, the more self-effective they feel – and the more stable the therapeutic relationship becomes, creating space for more challenging issues to be addressed later.

Who is trauma therapy suitable for – in cases of PTSD, complex childhood trauma and dissociative disorders?

TIST was developed for the most severe category of trauma-related symptoms: dissociative disorders. Particularly following sexual or physical abuse in childhood, as well as following eating disorders, addiction pressures or chronic self-harming behaviour stemming from early childhood trauma and other traumas arising from developmental and relational contexts.

Traditional trauma therapy addresses these issues and helps with trauma-related adjustment problems following an accident or illness, with distressing traumatic events in adulthood, and with traumatised individuals experiencing toxic shame. Trauma therapy methods help people regain access to their own bodies and resources. The aim is not to ‘cure’ a disorder, but to foster growth in the wake of trauma.

Limits, criticism and outlook: Where is trauma-oriented psychotherapy heading?

As influential as the TIST trend is, a sober assessment is equally important. Critics note that the approach is heavily narrative in nature and that empirical efficacy studies still need to catch up. Modern psychotraumatology is, on the whole, a rapidly growing field; trauma research, developmental and attachment theory, and neurobiology are constantly providing new insights that need to be incorporated into treatment.

Clinical practice has long shown that multimodal approaches often better meet the real needs of traumatised people than monomethodic programmes.

The development towards greater security, greater inner cooperation and a reduced symptom burden takes time. Yet it is possible – even in the case of the most severe consequences of trauma.

Key points at a glance

·         TIST (‘Trauma-Informed Stabilisation Treatment’) is old wine in new bottles. It combines stabilisation and part-work into an integrative model of trauma therapy.

·         It is based on the established theory of structural dissociation (Nijenhuis, van der Hart, Steele), which explains how trauma fragments the personality.

·         As in other methods, inner parts are understood as survival strategies; the therapeutic approach is mindful, resource-oriented and compassionate.

·         Regulation of the nervous system – through breathing, grounding, imagery and deep relaxation – is given equal weight alongside work with inner parts.

·         TIST combines elements from EMDR, IFS, Somatic Experiencing, Brainspotting and ego-state therapy and differs little from established approaches to complex PTSD, eating disorder comorbidity and dissociative disorders.
