Mentalization-Based Therapy Guide: Best Worksheets and Techniques

Mentalization-Based TherapyTo neuroscientists, psychoanalysts, existential philosophers, and various types of mental health practitioners, the idea of mentalization is both foundational and captivating.

Use of the term “mentalizing” in academic papers increased from 10 to 2,750 between 1991 and 2011 (Bateman & Fonagy, 2013).

Mentalization-Based Therapy (MBT) makes “mentalizing” the focus of therapy and has been enthusiastically embraced by clinicians, therapists, and coaches.

We discuss MBT in depth below, including why it has become increasingly popular, and offer a few free worksheets to boot.

These science-based exercises explore fundamental aspects of positive psychology, including strengths, values, and self-compassion, and will give you the tools to enhance the wellbeing of your clients, students, or employees.

Mentalization-Based Therapy (MBT) Explained

Although mentalizing is an internal process, it is actually a social phenomenon. As humans, we form beliefs or ideas about the mental states of the people we interact with in daily life and in meaningful relationships. Our own mental states are influenced by these beliefs and determine how we feel, act, and respond to the world, which makes MBT an extremely important approach.

Mentalization-Based Therapy is an evidence-based treatment created for people with borderline personality disorder, but it can be utilized with other mental health issues.

The premise of this therapy is rooted in the concept of “mentalizing.” Mentalizing is the ability to identify and differentiate one’s own emotional state from that of others (Bateman & Fonagy, 2013).

It is the ability to understand how our mental state influences behavior and emotions. Essentially, mentalization describes the common psychological process people use to understand the mental states, emotions, beliefs, desires, and intentions that are the basis of interpersonal interactions.

Because the ability to mentalize is foundational to psychological health and resilience, the main goals of MBT are to improve mentalization and learn emotional regulation. MBT includes elements from psychodynamic, cognitive-behavioral, systemic, and social-ecological therapies (Lois et al., 2016).

MBT practitioners try to establish a secure therapeutic attachment with patients and create a safe environment so clients can explore personal feelings and the feelings of others to develop their capacity to mentalize.

Much of MBT is grounded in attachment theory, in which infants activate attachment by communicating emotional distress with their caretakers. Secure attachment facilitates the development of healthy mentalization (Fonagy & Allison, 2014).

However, individuals with borderline personality disorder (BPD) commonly have preoccupied, fearful, distrustful, hostile, and disorganized attachment, which is addressed in MBT. The attachment style of BPD clients is one that fails to establish and regulate a sense of safety, creating distress, unhealthy vulnerability, and emotional dysregulation (Lois et al., 2016).

The ability to mentalize helps those with BPD understand their mental states, stabilize emotions, develop empathy, and improve interpersonal relationships.

MBT Treatment: 4 Evidence-Based Findings

MBT TreatmentMBT was designed to be a highly structured, manualized therapy to treat difficulties associated with borderline personality disorder by working within the context of attachment theory (Bateman & Fonagy, 2009).

Because people with BPD are characterized by insecure attachment, the improvement in mentalizing helps them develop healthy internal representations and improve psychological wellbeing.

Randomized control trials

While randomized controlled trials (RCTs) of MBT are limited, a few have demonstrated promising results. One of these included 53 individuals struggling with self-harm and borderline personality traits.

After a 12-week MBT intervention, social anxiety and self-harm behaviors decreased and emotional regulation improved (Griffiths et al., 2019). In this study, the ability to mentalize was a significant predictor of change in self-harm behavior and positive emotions.

In another RCT, 44 patients were randomly assigned to either a control or mentalization (MBT) group. Improvements in impulsivity, suicidal ideation, self-harm, and depression were significantly better in the MBT group after 18 months (Bateman & Fonagy, 2001).

Additionally, an eight-year follow-up demonstrated that the benefits are long lasting. The MBT group also had higher levels of social functioning and employment history, suggesting better interpersonal skills.

A study comparing outpatient therapy with structural clinical management showed that both treatments improved BPD patient outcomes (e.g., suicide risk, self-harm, psychotic episodes, and depression), but MBT provided more significant benefits (Bateman & Fonagy, 2013).

Both treatment groups received 50 minutes of structured therapy weekly for 18 months. Outcome measures were assessed at baseline, 6 months, and 18 months.

Review of research

A systematic review of 14 studies found that MBT led to significant reductions in self-reported symptoms of distress, suicide attempts, and self-harm (Vogt & Norman, 2019).

This review found that MBT reduced levels of anxiety and depression and helped increase the quality of life among BPD patients. The positive effects were seen in hospital settings, inpatient and outpatient clinics, and through a variety of qualitative and quantitative research designs (Vogt & Norman, 2019).

As research on MBT for BPD continues to grow, the importance of mentalizing for emotional health and positive interpersonal relationships is highlighted. Empirical studies on MBT need to expand to other disorders and populations.

Types of disorders treated

While MBT was originally designed to treat borderline personality disorder, it has since been adapted to treat adolescents who struggle with depression and self-harm (Rossouw & Fonagy, 2012).

In a qualitative study, Johnson et al. (2016) found that MBT participants were better able to mentalize, had less self-hatred, and improved social functioning and interpersonal relationships after experiencing MBT.

In clinical settings, MBT has been effectively used to treat eating disorders, addictions, severe depression, and post-traumatic stress disorder (Surendra, 2019). It has also been reportedly used to treat social anxiety and specific forms of depression (Porter, 2021).


While MBT and Dialectical Behavior Therapy (DBT) are both effective at treating borderline personality disorder and have similar roots in CBT and goals of emotional regulation, there are some key differences between the two treatments.

MBT is a simple, common-sense approach that has practical advantages over DBT. Practitioners who use MBT need little formal training, whereas DBT requires skills coaching and a curriculum with handouts, worksheets, weekly individual therapy, and a consultation team to support therapists (Bateman & Fonagy, 1999).

In this way, MBT can become a basic and useful addition to a clinician’s practice.

5 Mentalization-Based Techniques

Specific techniques apply to MBT, which we discuss here.

1. Support & empathy

Empathetic statements strengthen rapport and the therapeutic relationship, which is an essential foundation of MBT (Bateman & Fonagy, 2006).

The therapist must be able to provide support, give the client autonomy, and judiciously praise them in order to elicit change. Empathy and support are critical to any form of therapy but are particularly important in MBT. Empathy and support create new, healthy bonds between client and therapist, which is essential to the attachment theory that MBT is grounded in.

2. Clarification

In MBT, the therapist needs to clarify and elaborate to get a detailed picture of behavioral sequences and associated feelings. This clarification helps the client make connections between actions and feelings (Bateman & Fonagy, 2006).

Clarification includes repeating statements back to the client and asking questions the client can answer clearly.

3. Exploration

With exploration, the client can develop a curiosity of thoughts, feelings, and motivations (Bateman & Fonagy, 2006).

This is also a technique that helps the client share the therapist’s perspective and consider alternative experiences of the same event. Exploration provides an opportunity for the client to work on interpersonal relationship skills.

4. Challenging

Challenging the client is a technique of exploring their underlying emotional state by confronting their perspective (Bateman & Fonagy, 2006). This technique is a balance of pushing the client into conflict and finding acceptance with alternate beliefs.

5. Transference

Transference is often used in MBT to direct the patient’s emotions toward the therapist in order to analyze them (Allen et al., 2003).

While transference has often been seen as a negative in therapy, it can have numerous benefits when used intentionally. It helps patients think before they react to their own feelings and the perceived feelings of others.

How Mentalization Therapy Works

Mentalizing TherapyClients who come for MBT treatment are often in a place of emotional dysregulation and mistrust.

In MBT, the therapist creates a “secure base” to promote healthy mentalization and emotional regulation (Lois et al., 2016).

Throughout treatment, therapists monitor levels of mentalizing, emotional arousal, and attachment as they fluctuate in session. The goal is to stimulate just enough emotional responsiveness to explore new perspectives and find meaning, but not so much that mentalizing collapses from overarousal (Lois et al., 2016).

The therapist explores the client’s ability to maintain and recover mentalizing when challenged by emotional interpersonal events, such as misunderstandings, disagreements, rejections, and intimacy. In treatment, developmental events and attachment figures are discussed to assess how well a person can mentalize within close relationships and when the ability to do so breaks down (Lois et al., 2016).

When poor mentalizing is seen (i.e., the client goes to extremes), the therapist intervenes with “contrary moves,” and the client is encouraged to find the missing vantage point (Bateman & Fonagy, 2012). This helps the client learn to find a balanced perspective. Eventually, the client can broaden overly rigid, reactive, unrealistic, and emotionally vacant perspectives and learn more appropriate interpersonal behaviors.

3 MBT Activities for Your Sessions

  1. The Dream Journey activity provided by the Center for Mentalization helps clients find a safe place. By taking time to relax each part of the body, the client can let go of physical and emotional tension and distress. Once the client is in a relaxed state, they are asked to imagine a pleasant place to be. This becomes their “safe space,” which can be an anchor for exploring negative, irrational, and problematic thoughts and feelings.
  2. The Mentalization Model activity helps clients with interpersonal relationships. In the activity, the client is asked to think about an important relationship in their life.
    • The first step is to ask the client to identify their personal feelings about the relationship, needs from the relationship, goals of the relationship, reasons to keep the relationship, and specific thoughts about the relationship.
    • The next step is to have the client do the same thing from the other person’s perspective, imagining the answers the other person would provide.
    • Finally, the client is asked to reflect on the differences between the perspectives (self and other) and what it was like to imagine the other person’s emotions, needs, goals, reasons, and thoughts.
  3. The Triune Brain activity is great for MBT sessions. It helps clients understand the three states of the brain: executive, emotional, and survival. After some psychoeducation on the three aspects of the brain, clients can identify specific examples of when each part of the brain is used and expressed in life.By simply identifying thoughts, emotions, and behaviors for which each area of the brain is responsible, clients can become more self-aware and learn the ability to mentalize.
