Cognitive Analytic Therapy (CAT) at Magna House Hospital

Cognitive Analytic Therapy (CAT) is a time-limited, integrative psychological therapy that blends ideas from cognitive therapy and psychoanalytic approaches. This therapeutic model is highly valued for its ability to provide individuals with a clear understanding of how their past experiences influence their current thoughts, emotions, and behaviours. It is particularly useful in treating individuals who face difficulties related to personality disorders, emotional dysregulation, complex trauma, and relationship challenges.

At our hospital, CAT plays a significant role in helping patients explore the underlying causes of their mental health struggles and offers practical solutions for change. Our approach is tailored to meet the unique needs of each individual, creating a therapeutic journey that emphasises self-awareness, understanding of relational patterns, and the development of healthier coping mechanisms. Through CAT, patients can break free from unhelpful behavioural cycles and build more fulfilling relationships with themselves and others.

What is Cognitive Analytic Therapy (CAT)?

Cognitive Analytic Therapy is a highly structured and collaborative form of psychotherapy that focuses on identifying and understanding patterns of thoughts, emotions, and behaviours that are rooted in past experiences and relationships. It was developed in the 1980s by Dr. Anthony Ryle, who combined elements from cognitive therapy with insights from psychoanalysis to create a therapy that addresses both the conscious and unconscious aspects of human experience.

At the heart of CAT is the idea that many of the problems individuals face in adulthood are shaped by relational patterns and coping strategies developed during childhood. These patterns, which may have served a protective function early in life, can become maladaptive and lead to emotional distress, relationship difficulties, and mental health challenges.

CAT offers individuals a clear framework for understanding these patterns and how they influence their present-day behaviour. Through the use of diagrams and written narratives, CAT helps individuals gain insight into their difficulties, develop more adaptive ways of relating to others, and ultimately make lasting changes in their thoughts, feelings, and behaviours.


Core Principles of Cognitive Analytic Therapy

Cognitive Analytic Therapy is grounded in several core principles that guide its practice. These principles shape the therapeutic process and ensure that CAT is a collaborative, patient-centred approach that encourages self-awareness and positive change.

1. Understanding Relational Patterns

One of the key principles of CAT is the recognition that early life experiences, particularly those involving relationships with caregivers, shape our beliefs about ourselves and others. These experiences give rise to relational patterns—ways of thinking, feeling, and behaving—that we carry into adulthood. While some of these patterns may be healthy and adaptive, others can become problematic and contribute to emotional distress, interpersonal difficulties, and mental health conditions.

CAT aims to help individuals identify and understand these relational patterns, exploring how they were formed and how they continue to impact their current relationships and emotional well-being. By recognising these patterns, individuals can begin to break free from unhelpful cycles and develop more effective ways of relating to themselves and others.

2. Collaboration and Joint Exploration

Unlike some other forms of therapy where the therapist takes on an expert role, CAT is a highly collaborative process. The therapist and the patient work together to explore the patient’s difficulties, with the therapist acting as a guide rather than an authority. This joint exploration helps to foster a sense of empowerment and encourages the patient to take an active role in their own recovery.

The collaborative nature of CAT means that the therapist and patient regularly review progress, discuss insights gained during therapy, and make decisions together about the direction of the therapy. This approach ensures that the therapy is tailored to the individual’s needs and goals, making it a highly personalised form of treatment.

3. Time-Limited and Goal-Oriented

CAT is a time-limited therapy, typically lasting between 16 and 24 sessions. This structured timeframe helps to keep the therapy focused and goal-oriented, encouraging both the therapist and the patient to work towards specific, achievable outcomes within a set period.

The time-limited nature of CAT ensures that individuals are able to make meaningful progress within a relatively short period, while also providing them with the tools and strategies they need to continue their growth and self-awareness beyond the therapy sessions.

4. Reformulation and Mapping

One of the unique aspects of CAT is the use of reformulation, a process in which the therapist and patient work together to create a written or diagrammatic summary of the individual’s difficulties. This reformulation helps to make sense of the patient’s experiences, providing a clear and structured narrative that links past relational experiences to current thoughts, feelings, and behaviours.

The reformulation often takes the form of a CAT diagram, which visually maps out the patient’s relational patterns and coping strategies. This diagram serves as a tool for reflection and self-awareness, helping the patient to understand how their difficulties have developed and how they can begin to change.


The Structure of Cognitive Analytic Therapy

Cognitive Analytic Therapy is divided into three main phases: the early phase (reformulation), the middle phase (recognition and revision), and the ending phase. Each of these phases plays a crucial role in the therapeutic process, guiding the individual through a structured journey of self-awareness, exploration, and change.

1. Early Phase: Reformulation

The early phase of CAT focuses on reformulation, where the therapist and patient work together to explore the patient’s difficulties and develop a shared understanding of the relational patterns that are contributing to their problems. This phase involves gathering information about the patient’s history, including their early relationships, significant life events, and current challenges.

During this phase, the therapist may ask the patient to keep a diary or journal, recording their thoughts, feelings, and behaviours in specific situations. This helps to identify recurring patterns and themes, which are then used to create a reformulation letter or CAT diagram. The reformulation letter is a written summary of the patient’s difficulties, while the CAT diagram visually maps out the relational patterns and coping strategies that are contributing to the patient’s distress.

The reformulation process is highly collaborative, with the therapist and patient discussing the content of the letter or diagram together. This ensures that the patient feels understood and that the reformulation accurately reflects their experiences.

2. Middle Phase: Recognition and Revision

The middle phase of CAT is focused on recognition and revision. In this phase, the patient begins to recognise how their relational patterns and coping strategies are contributing to their current difficulties. The CAT diagram serves as a key tool during this phase, helping the patient to identify when they are falling into unhelpful patterns and providing them with a visual map of their behaviour.

Once the patient has developed an awareness of their patterns, the focus shifts to revision—the process of making changes to these patterns. The therapist works with the patient to develop new ways of thinking, feeling, and behaving that are more adaptive and aligned with the patient’s goals. This may involve practising new coping strategies, exploring alternative ways of responding to difficult situations, and developing healthier relational dynamics.

The middle phase of CAT is highly active and focused on change. The patient is encouraged to experiment with new behaviours and reflect on the impact of these changes in their day-to-day life. Throughout this phase, the therapist provides support and guidance, helping the patient to stay focused on their goals and work through any challenges that arise.

3. Ending Phase

The ending phase of CAT is an important part of the therapeutic process, as it helps the patient to consolidate their progress and prepare for life after therapy. During this phase, the therapist and patient review the work that has been done, reflect on the changes that have been made, and discuss how the patient can continue to apply the insights and skills they have gained.

The ending phase often involves a discussion of endings in general, as CAT recognises that many individuals have difficulty with endings due to past relational experiences. This phase provides an opportunity to explore any feelings of loss, anxiety, or uncertainty that may arise as therapy comes to a close and to work through these emotions in a supportive environment.

At the end of CAT, the therapist may provide the patient with a goodbye letter, summarising the work that has been done and offering encouragement for the future. This letter serves as a reminder of the progress that has been made and the tools that the patient can continue to use in their ongoing journey of self-awareness and growth.


Conditions Treated by Cognitive Analytic Therapy

Cognitive Analytic Therapy is a highly versatile form of therapy that can be used to treat a wide range of mental health conditions. It is particularly effective for individuals who struggle with complex emotional and relational difficulties, as it helps to address the underlying patterns that contribute to these issues.

  • CAT is widely used in the treatment of personality disorders, particularly borderline personality disorder (BPD). Individuals with BPD often experience intense emotions, unstable relationships, and a strong fear of abandonment. CAT helps these individuals to understand how their relational patterns, formed in early life, contribute to their difficulties in managing emotions and relationships.

    By providing a clear framework for understanding these patterns, CAT helps individuals with BPD develop more adaptive ways of relating to others and managing their emotions, leading to improved emotional stability and healthier relationships.

  • CAT is also effective in treating anxiety and depression, particularly when these conditions are linked to relational difficulties. Many individuals with anxiety or depression have developed unhelpful coping strategies, such as avoidance or withdrawal, which perpetuate their symptoms.

    CAT helps individuals recognise these patterns and develop healthier ways of responding to stress, improving their emotional well-being and reducing symptoms of anxiety and depression.

  • For individuals who have experienced trauma or complex post-traumatic stress disorder (C-PTSD), CAT provides a safe and structured environment for exploring the impact of past relational experiences on current emotional and behavioural patterns. Many trauma survivors develop coping strategies that, while protective in the short term, become maladaptive over time.

    CAT helps individuals understand how these patterns were formed in response to trauma and provides them with the tools to develop more adaptive ways of coping, reducing the long-term impact of trauma on their mental health.

  • CAT has been used successfully in the treatment of eating disorders, such as anorexia nervosa and bulimia nervosa. These disorders often involve complex relational patterns and coping strategies related to control, self-worth, and emotional regulation.

    Through CAT, individuals with eating disorders can explore the underlying emotional and relational factors that contribute to their disordered eating behaviours. By developing a deeper understanding of these factors, they can begin to challenge their unhelpful patterns and develop healthier relationships with food and their bodies.

  • Many individuals seek CAT because they struggle with interpersonal and relationship difficulties, such as recurring conflicts, difficulty maintaining relationships, or feelings of loneliness and isolation. CAT helps these individuals to explore how their relational patterns, often formed in early life, are contributing to their difficulties in building and maintaining healthy relationships.

    By gaining insight into these patterns, individuals can develop more adaptive ways of relating to others, improving their relationships and overall well-being.


The Benefits of Cognitive Analytic Therapy

Cognitive Analytic Therapy offers numerous benefits for individuals struggling with emotional and relational difficulties. Some of the key benefits include:

1. Increased Self-Awareness

One of the primary goals of CAT is to help individuals develop a deeper understanding of their thoughts, emotions, and behaviours. By exploring the relational patterns that underlie their difficulties, individuals gain greater self-awareness, which is the first step towards making meaningful changes.

2. Practical Tools for Change

CAT is a highly practical form of therapy that provides individuals with clear tools and strategies for change. The use of CAT diagrams and reformulation letters helps individuals to identify their patterns and develop new ways of responding to difficult situations, making the therapy both insightful and action-oriented.

3. Improved Relationships

Many of the difficulties addressed in CAT are rooted in relational patterns. By helping individuals understand how these patterns influence their relationships, CAT provides a pathway to healthier, more fulfilling connections with others.

4. Time-Limited and Focused

The time-limited nature of CAT ensures that therapy is focused and goal-oriented. Individuals can make significant progress within a relatively short period, gaining the tools they need to continue their growth and development after therapy has ended.

5. Collaborative and Empowering

CAT is a collaborative process that empowers individuals to take an active role in their own recovery. The joint exploration of difficulties fosters a sense of ownership and responsibility for change, which is essential for long-term success.


Cognitive Analytic Therapy offers a unique and powerful approach to understanding and addressing emotional and relational difficulties. By combining the strengths of cognitive therapy with insights from psychoanalysis, CAT provides individuals with a clear framework for exploring how their past experiences shape their present-day behaviour.

Through a structured, time-limited process, CAT helps individuals develop greater self-awareness, challenge unhelpful patterns, and make meaningful changes in their lives. Whether used to treat personality disorders, anxiety, depression, trauma, or interpersonal difficulties, CAT offers a pathway to recovery that is both practical and transformative.

Our approach to CAT ensures that each patient receives personalised, collaborative care that empowers them to take control of their mental health and build a more fulfilling future.
