Mentalization-Based Treatment

A baseline first-level MBT intervention in which the therapist acknowledges and confirms the client's emotional experience as understandable and warranted. Builds a shared emotional ground — the client feels they have been understood. It is the mandatory first step of any session and the point of return when affective arousal is high.

• 1. Listen carefully to the client's narrative without interrupting or interpreting
• 2. Reflect the emotional content of what was said using marked mirroring — show that you understand the feeling, but it is your understanding, not certain knowledge
• 3. Name the affect you noticed in a soft, suggestive form
• 4. Normalize the client's experience: show that in the given circumstances such a reaction is understandable
• 5. Make sure the client feels heard before moving on to inquiry

When to use:

• At the start of each session, to establish contact
• When the client's emotional arousal is high and mentalization is at risk
• After a crisis event or self-harm, before starting an inquiry

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not confuse with surface comforting or going along — validation does not mean agreement with dysfunctional behavior
• ⚠️ Avoid moving to inquiry too soon — first the client must feel understood
• ⚠️ Do not turn validation into interpretation: "I understand you" is not "I know why you feel this way"

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A second-level intervention aimed at clarifying the factual and emotional details of the client's experience. In MBT, clarification is not just gathering facts, but inquiring how the client understands their own and others' mental states in a concrete situation. The aim — to help the client slow down and look at their experience more attentively.

• 1. Quickly establish the facts of the situation: when it happened, who was present, what is the context
• 2. Clarify the sequence of events: what happened first, what next
• 3. Ask about the client's inner state at each key moment: "What did you feel when."
• 4. Clarify how the client understood the other person's behavior: "Why do you think they acted this way?"
• 5. Highlight any discrepancies between the facts and the client's interpretation
• 6. Give a brief summary: "If I understand correctly, what happened is this."

When to use:

• After empathic validation, when the client is stable and ready for inquiry
• When the client's narrative is tangled, chaotic, or contradictory
• When the client mixes facts and interpretations

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not turn clarification into an interrogation — the tone must remain curious and friendly
• ⚠️ Do not ask "why?" — it provokes rationalization. Instead, ask "what did you feel?" and "how was it for you?"
• ⚠️ Do not rush to interpretations — clarification should help the client to see the picture more clearly themselves

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A central MBT technique aimed at identifying and naming the affective component of the client's experience in the current moment of the session. The therapist defines the "affective focus of the session" — the immediate emotional content here and now. Stabilizing emotional expression is the primary task of MBT, without which serious inquiry into inner representations is impossible.

• 1. Identify the dominant affect of the client at this moment (not in the history, but here and now)
• 2. Name the affect in a soft, suggestive form: "It seems to me that right now you feel."
• 3. If the client struggles to identify the feeling, gently offer options: "If I were in your place, I might feel."
• 4. Link the affect to a specific interpersonal situation or relationship
• 5. Inquire how this affect influences the client's capacity to think about themselves and others
• 6. Track changes in affect during the session and bring attention to them

When to use:

• When the client speaks about events but is not in contact with emotions
• When the client's emotions are uncontrollably rising — to name and "tame" them
• When the key theme of the session needs to be identified

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not impose your interpretation of the affect on the client — it is a suggestion, not a statement
• ⚠️ Watch the level of arousal: if the affect is too intense, return to empathic validation
• ⚠️ Do not intellectualize feelings — focus on the experience, not on the explanation

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

An advanced MBT technique in which the therapist focuses the client's attention on the therapeutic relationship here and now, using it as a laboratory for inquiry into mental states. Unlike classical interpretation of transference, mentalization of the transference is aimed at activating mentalization in the context of a living, real attachment relationship. The therapist invites the client to think about the mind of another person (the therapist).

• 1. Notice the moment when the client's pattern of interpersonal relationships is being played out in the therapeutic interaction
• 2. Empathically validate the client's current experience
• 3. Gently bring the client's attention to what is happening between you right now: "It seems to me something is happening between us"
• 4. Invite the client to inquire what, in their view, the therapist thinks or feels: "What do you think I feel right now?"
• 5. Share your own experience (transparently, in marked form): "In fact I feel. and this may differ from what you assumed"
• 6. Link this experience to other relationships of the client: "Does this happen with other people?"

When to use:

• When the dynamics of the therapeutic relationship reflect the patterns the client comes with
• When the client attributes certain feelings or motives to the therapist
• When tension or rupture arises between the therapist and the client

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Use only at a low level of affective arousal — at a high one, return to validation
• ⚠️ Do not turn it into an interpretation of transference in the classical psychoanalytic sense
• ⚠️ Do not be accusatory or confrontational — the tone is one of joint inquiry
• ⚠️ Be ready that disclosing your own feelings may amplify the client's anxiety

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

An emergency intervention in which the therapist interrupts the course of the session at a moment when the client's mentalization is collapsing. The therapist insists that the client stop and focus on the current moment of the rupture. This creates a "breath" — a space for restoring mentalization. The technique is like pressing the "pause" button on a process that is going out of control.

• 1. Notice signs of loss of mentalization: repeated accusations, certainty about the motives of others, emotional escalation, departure into abstract reasoning
• 2. Gently but firmly stop the client: "Let us stop for a second"
• 3. Name what you observe: "I notice that right now it has become hard for us to think about this"
• 4. Provide safety: "This is normal. Let us just stay with this for a moment"
• 5. Wait for the arousal to come down before moving on

When to use:

• When the client has clearly lost the capacity to mentalize (gone into one of the non-mentalizing modes)
• When emotional escalation threatens to lead to a rupture of the therapeutic alliance
• When the situation in the session is "overheating" and becomes unproductive

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not use authoritatively or controllingly — the stop is care, not punishment
• ⚠️ Do not move straight to inquiry — give the client time to "land"
• ⚠️ Do not blame the client for the loss of mentalization

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A key MBT intervention for working with moments of loss of mentalization. After the stop, the therapist invites the client to "rewind" — back to the moment when mentalization was still functioning — and then slowly inquire what exactly led to its loss. The technique helps the client see the process of "switching off" mentalization and discover the triggers.

• 1. Stop the process (as in the "stop and stand" technique)
• 2. Wait for the emotional arousal to come down to a manageable level
• 3. Invite the client to return to the moment when they could still think about the situation: "Let us go back. When we were talking about. you were calmer. What changed?"
• 4. Slowly, step by step, inquire into the path from mentalization to its loss
• 5. Help the client to identify the breaking point — the moment when mentalization "switched off"
• 6. Delicately inquire into the affects that may have led to the collapse
• 7. Link the discovered pattern to a wider picture of the client's life

When to use:

• After the "stop and stand" technique has stabilized the client
• When a collapse of mentalization has occurred during the session and there is the possibility to inquire into it
• When the client shows a recurring pattern of loss of mentalization in particular situations

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not pressure the client if they are not ready for the inquiry — sometimes it is enough just to stop
• ⚠️ The inquiry is possible only at a lowered level of arousal
• ⚠️ Do not interpret for the client — help them discover the pattern themselves

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

An MBT technique in which the therapist offers an alternative perspective opposite to the one in which the client is "stuck". When the client shows rigid, one-sided thinking, the therapist gently suggests considering the situation from another side. The aim — not to convince the client, but to help them restore the flexibility of thinking and the capacity to hold several perspectives at the same time.

• 1. Notice that the client is stuck in one extreme perspective (for example, "he hates me", "she did this on purpose")
• 2. First validate the client's current perspective: "I understand that this is how you see it"
• 3. Gently offer an alternative point of view: "I am curious whether there could be another explanation?"
• 4. Help the client consider the "missing angle" — the perspective they are not taking into account
• 5. Do not insist on your alternative — use it as an invitation to inquiry
• 6. If the client can hold both perspectives — mentalization is restored

When to use:

• When the client shows black-and-white thinking about the motives of other people
• When the client is sure they know exactly what another person thinks or feels
• When the client is stuck in an extreme emotional position without the possibility of seeing an alternative

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not use as a devaluing of the client's experience — the alternative is offered AFTER validation
• ⚠️ Do not argue with the client — if they are not ready to consider the alternative, step back
• ⚠️ Do not offer contrary moves at a high level of arousal — the client will take it as an attack

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A third-level MBT intervention in which the therapist gently but directly questions the client's habitual way of understanding themselves and others. The challenge is not a confrontation — it is an invitation to deeper inquiry into the emotional state behind a particular position or behavior. The aim — to "loosen" rigid patterns of thinking and stimulate new mentalization.

• 1. Make sure the client's level of affective arousal allows the challenge (not too high)
• 2. Note the observed contradiction: "You say it does not matter to you, but I notice that your voice trembles"
• 3. Gently invite to inquire into this contradiction together: "I am curious what stands behind this"
• 4. Ask about the underlying emotional state, not about behavior
• 5. Be ready to step back if the challenge increases the arousal rather than stimulating inquiry

When to use:

• When the client shows a noticeable discrepancy between words and non-verbal behavior
• When the client uses pseudomentalization (says the "right" things, but is not in contact with feelings)
• When the client avoids important topics by using intellectualization

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ The challenge is not a confrontation and not an accusation; the tone must be curious, not judgmental
• ⚠️ If arousal rises — step back to validation immediately
• ⚠️ Do not use with clients in acute crisis
• ⚠️ Do not challenge too often — it can undermine safety

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A fundamental therapeutic stance of MBT — not a technique in the narrow sense, but the basic position of the therapist that runs through the whole interaction. The therapist proceeds from the fact that they do NOT know the client's inner states better than the client themselves. It is a position of sincere curiosity, humility, and interest in the client's perspective. The therapist "sits beside" the client in a joint effort to understand what is happening.

• 1. Consciously let go of the position of expert — you do not know what the client feels, you can only ask
• 2. Phrase all hypotheses as suggestions: "It seems to me.", "I assume.", "Perhaps."
• 3. Actively monitor your own assumptions and errors in understanding the client
• 4. When you have been wrong — openly acknowledge it and inquire: "It looks as if I misunderstood you. Help me figure it out"
• 5. Ask "what?" questions instead of "why?" — they stimulate description of the experience, not rationalization
• 6. Stimulate the client's own insights, do not give ready interpretations

When to use:

• Always — this is the stance held throughout the whole therapy
• Especially when the therapist feels they "know" the client — that is precisely when the therapist's mentalization is at risk
• When the client resists interpretations — the not-knowing stance reduces resistance

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ The not-knowing stance is not passivity and not the absence of opinion; the therapist is actively inquiring
• ⚠️ Do not turn the not-knowing stance into a manipulation ("I pretend not to know")
• ⚠️ Sincerity is mandatory — clients quickly read inauthenticity

Bateman A.W. Fonagy P. (2004, 2016); Fonagy P. Luyten P. (2009)

Systematic monitoring by the therapist of the quality of the client's mentalization across the session. The therapist tracks signs of loss of mentalization, recognizes the move into non-mentalizing modes, and chooses the appropriate response. This is a diagnostic skill — the ability to tell in real time whether the client is mentalizing or has lost the capacity. Detecting a failure triggers the chain: stop → validate → rewind → inquire.

• 1. Monitor markers of loss of mentalization: rigidity of thinking, certainty about the motives of others, black-and-white judgments, repeated accusations, emotional escalation
• 2. Identify the specific non-mentalizing mode (psychic equivalence, pretend mode, teleological stance)
• 3. Gently name the noticed pattern: "I notice that right now it has become hard for us to think about feelings"
• 4. Choose the appropriate intervention: at high arousal — validation and stop; at low — inquiry and challenge
• 5. Help the client over time to notice moments of loss of mentalization themselves

When to use:

• Continuously, throughout the session — this is a background monitoring
• Especially attentive when discussing significant attachment relationships
• When the client becomes unusually certain in their judgments about others

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not shame the client for the loss of mentalization — it is a normal reaction to stress
• ⚠️ Name the process, do not evaluate: "It has become hard for us to think" instead of "you stopped thinking"
• ⚠️ Use "we", not "you" — emphasizing the joint nature of the process

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A technique for working with the non-mentalizing mode in which the client's inner reality is experienced as outer: what is thought and felt is taken as absolute truth. There is no gap between thought and reality. The client is absolutely sure of their interpretation and feels deep emotional pain without the possibility of seeing the situation otherwise. The therapist cannot directly contest the beliefs — first the arousal must be lowered and a "gap" between thought and reality created.

• 1. Recognize markers: absolute formulations ("he definitely.", "I know for sure."), the impossibility of considering an alternative, intense pain
• 2. Do NOT contest the client's beliefs directly — this will increase rigidity
• 3. Empathically validate the experience: "I see how real and painful this is for you"
• 4. Slowly introduce the element of "as if": "Suppose for a moment that another option is also possible."
• 5. Use the not-knowing stance: "It is hard for me to be sure — tell me what makes you think so?"
• 6. Gradually widen the space for alternative interpretations

When to use:

• When the client is absolutely sure of their interpretation of the situation, without any doubt
• When the client says: "I know for sure what he was thinking / what she was feeling"
• When the client's certainty causes intense distress

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Direct contestation of beliefs in psychic equivalence WILL amplify the distress and the rigidity
• ⚠️ Work slowly and carefully — change can take many sessions
• ⚠️ Begin with validation, not with challenge — the client needs to feel understood

Bateman A.W. Fonagy P. (2004, 2016); Fonagy P. (2002). Affect Regulation, Mentalization, and the Development of the Self

A technique for working with the non-mentalizing mode in which the client's thoughts and feelings are detached from reality. The client may seem to be "mentalizing well" — uses psychological language, builds complex explanations — but these reflections are not connected with real emotional experience. This is "mentalization in a vacuum" (hypermentalization). The client says the right words but does not feel what they are talking about.

• 1. Recognize markers: verbosity without emotional content, "smart" explanations, long abstract reasoning, the sense of an "empty" conversation in the therapist
• 2. Pay attention to your own sensations: boredom, loss of concentration — indicators of pretend mode
• 3. Gently interrupt the abstract reasoning: "Wait. I notice that we are saying many interesting things, but I have lost contact with what you feel"
• 4. Bring back to the concrete experience: "Let us go back to a concrete moment. What was happening with you when.?"
• 5. Ask to describe bodily sensations: "What do you feel in the body right now?"
• 6. If the client switches back to abstractions — gently bring back to the concrete again

When to use:

• When the conversation feels "empty" to the therapist — many words, few feelings
• When the client uses psychological jargon without real contact with emotions
• When the therapist catches themselves in boredom or loss of attention

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not blame the client for insincerity — pretend mode is often unconscious
• ⚠️ Be tactful: the client may be attached to their "clever" identity
• ⚠️ Do not confuse hypermentalization with real reflection — the difference is in the presence of affect

Bateman A.W. Fonagy P. (2004, 2016); Fonagy P. (2002). Affect Regulation, Mentalization, and the Development of the Self

A technique for working with the non-mentalizing mode in which the client only recognizes observable, physical actions and outcomes as real. Mental states do not "count" — only concrete deeds matter. Self-harm in the teleological mode can be an attempt to influence others through visible action. Suicide attempts can reflect teleological logic: "Only if I do something serious will they understand".

• 1. Recognize markers: a demand for concrete actions as proof of feelings, the devaluing of words, self-harm as communication
• 2. Validate the client's need for concrete proofs: "I understand that for you it is important to see real confirmations"
• 3. Gently bring attention to the fact that thoughts and feelings are also real: "I am curious why words seem insufficient"
• 4. Link the teleological stance to the history of attachment: "Were there situations in your life when words really meant nothing?"
• 5. Model the value of inner states through your own stance

When to use:

• When the client evaluates the relationship exclusively through concrete actions
• When self-harm or destructive behavior is used as a way of communication
• When the client demands "proofs" of care from the therapist through concrete actions

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not moralize about self-harm — inquire into its function
• ⚠️ Do not enter into arguments "words vs deeds" — first understand the client's logic
• ⚠️ The teleological stance can be especially stubborn — the work requires patience
• ⚠️ Take safety into account: if self-harm is life-threatening — first the crisis protocol

Bateman A.W. Fonagy P. (2004, 2016); Fonagy P. (2002). Affect Regulation, Mentalization, and the Development of the Self

An advanced fourth-level technique in which the therapist addresses the interaction between therapist and client as the object of mentalization. Unlike mentalization of the transference, relational mentalizing focuses on the process of the relationship as a whole — how it develops, what patterns are forming, how both participants influence each other. Used only at a low level of arousal.

• 1. Make sure of the stability of the therapeutic alliance and a low level of arousal
• 2. Bring the client's attention to a pattern in your relationship: "I noticed that in the last few sessions."
• 3. Invite the client to inquire into this pattern together: "I am curious what you think about this"
• 4. Openly share your experience: "I feel that."
• 5. Link the pattern in the therapeutic relationship with patterns in the client's life
• 6. Help the client see their contribution to the formation of the pattern without blame

When to use:

• When a stable recurring pattern has formed in the therapeutic relationship
• When the client is stable enough for work at this level
• When the therapeutic relationship reflects the client's main difficulties in relationships

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Use ONLY at a low level of arousal — at a high one, return to validation
• ⚠️ Do not do it too often — it can become intrusive and trigger anxiety
• ⚠️ Be ready for the client to take this as criticism
• ⚠️ The therapist's own mentalization matters — check your motives

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A technique for integrating bodily experience into the process of mentalization. The therapist helps the client to establish the link between mental states and bodily sensations — to learn to "read" their body as a source of information about feelings. Especially important for clients with alexithymia, somatization, and dissociative states.

• 1. When the client speaks about feelings or struggles to name them, direct attention to the body: "Where in the body do you feel this?"
• 2. Help to describe the bodily sensation in detail: "What kind of sensation is it? Heaviness, tightness, warmth, coldness?"
• 3. Link the bodily sensation with the emotional state: "What, in your view, is the body trying to tell you?"
• 4. Use the breath as an anchor for returning to bodily awareness
• 5. Help the client notice how the bodily sensations change while talking about different topics
• 6. Gradually build a "vocabulary" of the client's bodily sensations and their link to emotions

When to use:

• When the client struggles to identify their emotions (alexithymia)
• When the client presents somatic complaints without a clear organic cause
• When the client tends to intellectualize and "go into the head"
• When working with dissociative states for "grounding"

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not force — some clients may be afraid of contact with the body (trauma, dissociation)
• ⚠️ Take the cultural context into account — not all clients are used to talking about the body
• ⚠️ With dissociative reactions — work slowly and with reliance on safety

Luyten P. Fonagy P. (2012); Luyten P. Van Houdenhove B. Lemma A. Target M. Fonagy P. (2012)

Specific interventions for group MBT therapy in which the group is used as a living laboratory for developing interpersonal mentalization. The key ingredient — a structure of taking turns to speak, in which 2–3 participants inquire into interpersonal events, and the rest take part as responsible partners. The group creates the conditions for the development of epistemic trust and mentalization in real time.

• 1. Establish the rules of the group: safety, respect, curiosity about each other's perspectives
• 2. At the start of the session identify 2–3 participants who want to inquire into an interpersonal event
• 3. The speaker tells about the situation; the leader helps them to mentalize
• 4. Other participants are invited to inquire: "What do you think they felt?"
• 5. The leader tracks failures of mentalization in the group and gently brings the process back
• 6. Use moments of tension between participants as material for mentalization
• 7. At the end — joint reflection on the process

When to use:

• Within a structured MBT-G program (usually 1/week, in parallel with individual therapy)
• To develop the skills of interpersonal mentalization in real time
• When the client finds it hard to carry the experience from individual therapy into real life

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ The leader must actively manage the level of arousal in the group
• ⚠️ Do not let the group turn into "advisors" — focus on inquiry, not on solutions
• ⚠️ Watch safety: some participants may regress in a group context
• ⚠️ On loss of mentalization in several participants at once — use "stop and stand" for the whole group

Bateman A.W. Fonagy P. (2016); Bateman A.W. (2023). Cambridge Guide to Mentalization-Based Treatment

A specific protocol for working with crisis situations within MBT. The crisis is seen as the result of a complete collapse of mentalization under the impact of intense activation of the attachment system. The therapist does not act "for" the client (this is a teleological response), but helps to restore minimal mentalization under crisis conditions. The crisis plan is built jointly, in advance, while the client is still able to mentalize.

• 1. Before the crisis: jointly build a crisis plan — what to do, whom to call, what steps to take
• 2. In the moment of crisis — empathic validation: "I hear that you are feeling very bad right now"
• 3. Help to identify the current affect: "What do you feel right now?"
• 4. Do NOT ask "why?" — only "what?" and "how?"
• 5. Help to restore minimal mentalization: "Let us try to understand together what happened"
• 6. Link the crisis with the loss of mentalization: "At some point it became so painful that you stopped being able to think"
• 7. Restore the sense of agency: "What, according to your crisis plan, can you do right now?"

When to use:

• On suicidal thoughts or self-harm of the client
• On emotional breakdowns between sessions (telephone contact)
• On flare-ups of BPD symptoms (impulsivity, dissociation, destructive behavior)

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not yourself fall into the teleological mode (do not "rescue" through actions without mentalization)
• ⚠️ Do not minimize the crisis: "Everything will be fine" — that is NOT MBT
• ⚠️ If there is a real threat to life — first the safety protocol; mentalization is secondary
• ⚠️ Do not analyze the crisis in detail in the moment of the crisis — there is the next session for that

Bateman A.W. Fonagy P. (2004, 2016). Mentalization-Based Treatment for Personality Disorders

A technique from attachment research, brought into the therapeutic context of MBT. When a small child cries, an adequate caregiver reflects their state, but in a transformed, "marked" form. In MBT therapy, the therapist reflects the client's affect in a transformed form that simultaneously validates the experience and offers an alternative representation of it.

• 1. Accurately recognize the client's emotional state (contingency)
• 2. Reflect it in a transformed form: not as an exact copy, but as a "digested" version
• 3. Mark the reflection: show that this is your understanding, not a statement of fact ("It seems to me that you.", "Maybe you feel.")
• 4. Add an element of an alternative perspective: "And perhaps something else stands behind this."
• 5. Check the accuracy of the reflection: "Is that so?"

When to use:

• Throughout the whole therapy as a base way of responding
• Especially at high affective arousal — helps to "digest" intense feelings
• When the client struggles to understand what they feel

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not get infected by the client's affect (do not mirror literally) — the therapist reflects but stays stable
• ⚠️ Marking is mandatory — without it the reflection can be felt as an intrusion
• ⚠️ Do not turn it into interpretation: "You feel X because of Y" — that is no longer mirroring

Fonagy P. Gergely G. Jurist E. Target M. (2002); Bateman A.W. Fonagy P. (2016)

A specific MBT intervention for working with moments of disturbance in the therapeutic alliance. Ruptures are seen not as problems but as valuable opportunities for mentalization — it is precisely in the moment of rupture that the client can learn that another mind can be useful even if it has been wrong. A key element — the therapist's readiness to openly acknowledge their own mistake or contribution to the rupture.

• 1. Notice signs of rupture: the client closing off, sudden aggression, passivity, withdrawal
• 2. Stop the current process and name what is happening: "It seems to me that something has changed between us"
• 3. Openly acknowledge your possible contribution: "I think I may have hurt you when I said."
• 4. Invite to inquire: "Help me understand what you feel right now"
• 5. Do not defend yourself — even if the client's reaction seems excessive
• 6. Use the rupture as material for mentalization
• 7. Restore contact through validation and empathy

When to use:

• When the therapeutic alliance is disturbed (the client has withdrawn, become angry, fallen silent)
• When the therapist has realized their mistake (an inaccurate interpretation, an untimely challenge)
• When the client expresses dissatisfaction with therapy or with the therapist

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not defend yourself — that kills mentalization. Acknowledging the mistake is a strength, not a weakness
• ⚠️ Do not ignore ruptures — unaddressed ruptures destroy therapy
• ⚠️ Do not over-apologize — that can shift the focus to the therapist

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

The starting level of MBT interventions — the active, deliberate expression of understanding of the client's experience. Unlike empathic validation (confirming that feelings are warranted), basic empathy is the demonstration that the therapist is trying to feel into the client's world, using marked mirroring. The therapist reflects the experience, showing that this is their understanding, not exact knowledge.

• 1. Listen not only to the words, but to the non-verbal signals: tone of voice, posture, facial expression
• 2. Phrase your understanding of the client's experience as a marked reflection: "I hear that you felt."
• 3. Use contingent mirroring — the reflection should match the client's state, but in a transformed form (not an exact copy of the affect, but its "digested" version)
• 4. Check the accuracy of your understanding: "Is that so?"
• 5. Be ready to correct your understanding on the basis of the client's feedback

When to use:

• Throughout the session as a background process
• Especially at the start of therapy and in establishing the alliance
• When the client feels misunderstood or alone in their experience

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Marked mirroring means "I understand that you feel this", not "I feel the same" (affect contagion)
• ⚠️ Do not merge emotionally with the client — keep the position of observing participation
• ⚠️ Avoid the cliché "I understand you" without real emotional joining

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A technique of active joint inquiry into the client's inner world, aimed at widening and deepening the understanding of one's own mental states. The therapist helps the client move from a surface description of events to a multi-layered understanding of the linked thoughts, feelings, and motives — both their own and other people's. This is not interpretation, but a joint process of "digging up" meaning.

• 1. Start with what the client has already said and ask them to tell more: "Tell me more about this feeling"
• 2. Ask open questions: "How did it feel?", "What was happening inside you?"
• 3. Inquire into multiple perspectives: "And what do you think they felt at that moment?"
• 4. Widen the context: "Has something similar happened to you before?"
• 5. Help the client to notice the links between feelings, thoughts, and actions
• 6. Support the process of inquiry, even if it leads to uncertainty

When to use:

• When the client is stable and capable of reflection (low/moderate level of arousal)
• When the client describes the situation superficially, without emotional depth
• When a new theme or pattern arises that is worth inquiring into

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Do not interrogate — the inquiry must be joint and curious
• ⚠️ Watch the level of arousal — if the inquiry causes distress, return to validation
• ⚠️ Do not rush the client to conclusions — the value is in the very process of inquiry

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

Continuous observation by the therapist of three key parameters throughout the session: (1) the client's level of mentalization, (2) the level of emotional arousal, (3) the degree of activation of the attachment system. These three parameters determine the choice of interventions at every moment. The aim — to maintain the optimal zone: enough emotion that the inquiry is meaningful, but not so much that mentalization breaks down.

• 1. Continuously track the non-verbal markers of arousal: changes in voice, posture, facial expression, breath
• 2. Assess the quality of mentalization: is the client speaking flexibly or rigidly? Are they taking the perspective of others?
• 3. Determine the degree of activation of attachment: does the current theme touch significant relationships?
• 4. Choose the level of intervention: high arousal → empathy, validation; medium → clarification, challenge; low → mentalization of the relationship
• 5. Switch flexibly between the levels as the client's state changes

When to use:

• Continuously, throughout the session — this is a background process
• Especially important at transitions between themes
• Critical when discussing trigger themes (attachment relationships, losses, betrayals)

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ Monitoring must not paralyze the therapist — over time it becomes automatic
• ⚠️ Errors in the assessment of the level — are normal; what matters is the ability to correct quickly
• ⚠️ The therapist's own arousal also needs to be monitored

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A technique of joint creation of a coherent, meaningful narrative about the client's life with a focus on mental states. In MBT the case formulation is developed jointly and gradually becomes the client's "property". A mentalizing narrative is a story in which people's behavior becomes understandable through their thoughts, feelings, and motives. It helps the client to build a whole, non-contradictory image of themselves.

• 1. At the start of therapy jointly identify the key themes and patterns: "Let us try to understand together what usually happens when you feel bad"
• 2. Help the client to describe situations through mental states: "What did you feel? What, in your view, did mother feel?"
• 3. Link the current patterns with the life history
• 4. Gradually form a joint narrative about how the life history led to the current difficulties
• 5. Regularly come back to the narrative and update it
• 6. Encourage the client to take "authorship" of the narrative: "How would you yourself describe this pattern?"

When to use:

• At the start of therapy — when building the case formulation
• When new material appears that changes the understanding of the client's patterns
• When the client finds it hard to see the link between the past and the present

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ The narrative must be joint, not imposed by the therapist
• ⚠️ Do not rush with the formulation — it forms gradually
• ⚠️ The narrative must not be rigid — it changes as therapy unfolds
• ⚠️ Avoid intellectualized stories without emotional content

Bateman A.W. Fonagy P. (2016). Mentalization-Based Treatment for Personality Disorders

A general model of structuring MBT interventions, describing the cyclical process of the therapist's work: (1) noticing the loss of mentalization → (2) stop → (3) return to the mentalizing moment → (4) joint inquiry → (5) widening of perspective → (6) mentalization of the relationship (if appropriate). The cycle sets the rhythm of the therapeutic work and helps the therapist not to "get lost" in the material.

• 1. Notice — continuously monitor the quality of the client's mentalization
• 2. Stop — on loss of mentalization gently interrupt the process
• 3. Rewind — return to the moment when mentalization was still working
• 4. Inquire — together with the client inquire what led to the loss
• 5. Widen — help to see alternative perspectives
• 6. Mentalize the relationship — if appropriate, link with the therapeutic relationship
• 7. Repeat — the cycle starts again at the next loss of mentalization

When to use:

• As a general principle for organizing every MBT session
• When the therapist feels that they have "got lost" in the material and do not know what to do
• As a guide for supervision

Key phrases:

Follow-up questions:

Warnings:

• ⚠️ The cycle is not a rigid algorithm, but a flexible guide. Not all steps are mandatory each time
• ⚠️ Do not force progress through the cycle — sometimes it is enough to stop and validate
• ⚠️ Do not use it as a formula — every session is unique
