• To propose future directions for research and practice, emphasizing strengthening the evidence base through rigorous study designs.^[2,12]

Theoretical foundations of cognitive analytic therapy

CAT is distinct from traditional cognitive behavioral therapy (CBT) since it uses an integrated framework that combines cognitive, relational, and developmental theories. CBT, on the other hand, primarily focuses on cognitive distortions and behavioral patterns.^[13] CAT's focus on “reciprocal roles” and “problem processes” connects past relationships to current problems and gives us a deeper look at how people interact with each other.^[2] CAT's collaborative tools, like the reformulation letter and sequential diagrammatic reformulation (SDR), help clients understand and get involved, which makes it especially useful for conditions with complicated relationships, like borderline personality disorder.^[5] CBT is very structured and based on research, yet it may not be the best way to deal with long-standing patterns of behavior amongst people. CAT's flexible approach, which lasts for 16 to 24 sessions, strikes a balance between depth and practicality. This is helpful in places like the NHS where resources are restricted.^[2] Fundamentally, CAT is based on the idea that maladaptive thought, emotion, and behavior patterns, which the therapy refers to as “problem procedures”, cause psychological distress.^[14] These are ingrained methods of interacting with oneself and others, shaped by early life experiences and internalized through key relational interactions.^[15] According to CAT's theoretical model, these problematic patterns appear as “reciprocal roles,” in which people unintentionally reproduce dysfunctional dynamics that originate from formative relationships.^[16] According to this model, early negative experiences frequently lead to inflexible interpersonal roles that, if left unchanged, prolong psychological suffering into adulthood. CAT provides a structured framework that enables clinicians to work collaboratively with clients, mapping recurring patterns and fostering insight into the relational context underlying the client's current difficulties.^[17] By emphasizing interpersonal patterns and internal cognitive processes, CAT effectively integrates relational and developmental theories with cognitive therapy.^[1] A more thorough comprehension of a client's challenges is made possible by incorporating relational and cognitive approaches into CAT.^[18] For example, when applied to personality disorders or cases involving complex trauma, the therapy aids in identifying how deeply ingrained relational patterns exacerbate symptoms.^[5,2,19] By collaboratively working through these patterns, clinicians and clients can explore alternative ways of relating that might reduce distress and promote adaptive functioning.^[20]

Problem procedures and reciprocal roles

A distinguishing feature of CAT is its emphasis on “problem procedures”.^[21] These refer to established but maladaptive ways of thinking, feeling, and behaving acquired early in development.^[22] The individual’s internal narrative often maintains problem procedures and is deeply intertwined with expectations about self and others. The concept of “reciprocal roles” further elaborates on this by positing that individuals adopt fixed roles within their interpersonal relationships.^[23] These roles are templates formed in response to early interactions and continue to influence behavior long into adulthood.^[1] Recognizing these reciprocal roles in a client’s relational history is a critical step in CAT. Through a collaboratively constructed reformulation, clinicians help clients identify the dysfunctional patterns that may have served as protective mechanisms but now contribute to distress. As clients become more aware of these patterns, they are empowered to challenge and alter them.^[24]

Collaborative reformulation and the therapeutic process

Collaborative reformulation is a central component of the CAT methodology.^[25] This process involves creating a shared understanding or “map” of the client’s problem procedures and their origins. Through this dialogue, the therapist and client identify the stages in which maladaptive patterns were formed and understand how these influences continue to shape current relationships.^[25-27] This collaborative process builds insight and forms the basis for subsequent therapeutic intervention. The process of reformulation in CAT is typically followed by the stages of recognition and revision, which will be discussed in greater detail in the upcoming section on therapeutic stages.^[27] Together, these phases ensure that the client gains insight and practical strategies for change. In so doing, CAT contributes to sustained improvements in psychological well-being.^[25]

Stages of therapy in cognitive analytic therapy

CAT is characterized by its structured yet flexible therapeutic process. The treatment generally contains three primary stages, each designed to build progressively upon the previous phase: reformulation, recognition, and revision.^[2,25]

• Reformulation stage

When a patient and therapist work together to write or diagrammatically summarize the person's challenges, this is known as reformulation.^[28] By offering a concise and well-organized narrative that connects previous relational experiences to present-day ideas, emotions, and behaviors, this reformulation helps make sense of the patient's experiences. The goal of the reformulation phase, the first stage of CAT^[29], is to establish a clear, mutual understanding of the client's problems. At this point, the client and therapist collaborate to create a narrative that illustrates the client's approach to resolving issues and the respective roles each party plays in the relationship. The therapist prepares for a more thorough examination of the underlying relational dynamics by fusing the client's past with present issues. This phase typically occurs early in CAT, usually within the first three to six sessions of a typical course of therapy that lasts sixteen to twenty-four sessions.^[1,12] The primary purpose is to help the client and the therapist develop a shared understanding of the client's emotional difficulties, relationships, and recurrent behavioral patterns.^[30,7] The goal of this structured and cooperative stage is to provide the client with a clear, nonjudgmental account of their struggles, which will serve as a guide for the remainder of the therapy.^[7,31,32] To put it another way, the reformulation often takes the form of a CAT diagram, which visually represents the patient's coping mechanisms and relational patterns. As a tool for introspection and self-awareness, this diagram helps patients understand how their challenges have arisen and how they can begin to confront and address them.^[1,33]

Key components of the reformulation stage

The reformulation stage involves several structured activities and tools that are developed collaboratively between the therapist and the client. These include:

• Gathering information

The therapist conducts a thorough psychotherapeutic assessment by asking open-ended questions, reviewing the client's case history, and discussing current problems and distortions. This involves examining childhood experiences, relationships, and significant life events to determine the origins of bad habits.^[1] The client completes a structured questionnaire to gather information, prompting reflection on personal history, relationships, and recurring difficulties. The questionnaire helps identify traps, dilemmas, and snags. The therapist also includes the clients’ verbal and written accounts of their lives, challenges, and goals during sessions.^[5,35]

• Identifying reciprocal roles

Reciprocal roles (RRs) are patterns of interaction learned early in life, often from relationships with caregivers or significant others, that shape how the client relates to themselves and others.^[5] The therapist and client identify these roles by exploring how early experiences (e.g., being criticized or neglected) have led to internalized patterns that persist in adulthood. For example, a client who experienced a critical parent may adopt a “critical–criticized” role, where they either blister themselves or expect criticism from others.Reciprocal roles help explain why clients repeat unhelpful relationship patterns and provide a framework for understanding emotional triggers and behaviors.^[4,5]

• Mapping target problem procedures (TPPs)

Target problem procedures are repetitive, unhelpful patterns of behavior, thoughts, or emotions that maintain the client’s difficulties. These are sequences (e.g., “If I feel rejected, I withdraw, which leads to more isolation”).^[1,34]

• Sequential diagrammatic reformulation (SDR)

The SDR, also called a “map” or “diagram,” visually represents the client’s reciprocal roles and procedures. It illustrates how early experiences lead to specific roles, manifesting as problematic adult behaviors.^[35,36] During therapy,the therapist draws a diagram with the client, linking reciprocal roles to specific behaviors, emotions, and outcomes. The SDR provides a visual tool that clients can refer to throughout therapy to understand and track their patterns. It is often revisited and refined as therapy progresses.^[37,38]

• Reformulation letter

The reformulation letter is a written narrative, typically drafted by the therapist and shared with the client around sessions 4–6. It summarizes the client’s life story, key reciprocal roles, target problem procedures, and therapy goals in a compassionate, nonjudgmental tone.^[39]

Process of the reformulation stage

Drafting and sharing the reformulation letter:

Around sessions 4–6, the therapist presents the reformulation letter, synthesising the client’s history and patterns. The client’s feedback is incorporated to ensure accuracy and alignment.^{[1,32,40,42,]}

Monitoring and self-observation

Clients are encouraged to actively monitor their thoughts, emotions, and behaviors outside therapy sessions, using the reformulation framework as a guide. They may be asked to keep a diary or note instances where they notice their patterns (e.g., “I avoided a social event because I feared rejection”).^[6]

Techniques:

• Self-monitoring exercises: Clients track specific situations where TPPs (traps, dilemmas, or snags) are triggered, noting the context, emotions, and outcomes.^[16]

• Rating sheets: Clients may use structured forms to rate the frequency or intensity of specific patterns, helping them quantify and reflect on their behaviors.^[2]

• In-session reflection: The therapist facilitates discussions about recent events, helping the client relate them to the SDR or reformulation letter.^[6,2]

Empirical evidence supporting cognitive analytic therapy’s effectiveness

CAT has gotten more and more scientific evidence for how well it works to address complex mental health issues like personality disorders, chronic pain, and psychosis. A key randomised controlled trial (RCT) by researchers^[49] showed that CAT worked better than treatment as usual for borderline personality disorder (BPD), with significant improvements in social functioning and fewer symptoms. The study demonstrated that CAT can modify long-standing patterns of behavioral and relationships through its collaborative reformulation process, which promotes insight and behavioral change.^[5] Some researchers^[50] also combine much clinical evidence to show that CAT's structured but flexible framework is perfect for personality disorders, because harmful roles keep people in distress. Their work shows how CAT's integrative approach combines cognitive and relational factors to get long-lasting therapeutic results. Some psychotherapists did a preliminary study of short CAT therapies for chronic pain and found that they significantly reduced pain-related suffering and improved psychological well-being in people.^[51] This study demonstrates that CAT's focus on mapping social dynamics and issue procedures helps clients reframe their pain experience, addressing both psychological and interpersonal elements.^[13] Some researchers did a case study on psychosis that showed that CAT works to lessen psychotic symptoms and improve how people get along with each other. CAT helped clients find and change harmful patterns related to psychotic experiences by employing SDR.^[52] This is a promising alternative to traditional CBT for psychosis.^[11] Some psychotherapists examined how CAT may be used in different situations and found that it worked well for treating complex trauma and personality disorders using a time-limited, relational approach.^[52] This adds to the evidence that CAT is flexible. Recent research, such as a case series by some researchers, supports these findings by showing that CAT can help people with severe mental health problems by helping them understand themselves and their problems better.^[43] Research in 2014 points out that these studies have several limitations, such as small sample sizes and the need for larger-scale RCTs. However, taken together, this evidence base shows that CAT is effective at treating complex conditions by using its integrative, collaborative framework. More rigorous studies are needed to strengthen its empirical foundation.^[33]

Use of CAT in different clinical conditions

CAT works well for complicated mental illnesses that cause many problems with relationships and social interactions, primarily when they are based on early experiences. Some important conditions are:

• BPD: CAT significantly improves interpersonal functioning and reduces symptoms in BPD, offering a time-limited (16–24 sessions) alternative to therapies like dialectical behavior therapy (DBT) by focusing on relational narratives.^[2,41,43]

• Eating disorders: CAT addresses relational triggers in anorexia and bulimia, improving symptom management compared to CBT’s symptom-focused approach.^[34,2]

• Chronic pain: CAT reduces pain-related distress and enhances coping by reframing emotional responses, complementing traditional pain management.^[13]

• Psychosis: CAT helps manage psychosis by integrating fragmented experiences and addressing relational triggers, offering advantages over CBT for psychosis.^[11]

Considerations for choosing CAT

Client suitability: CAT is most effective for clients who are psychologically minded, capable of reflecting on relationships, and motivated for time-limited work. Those with severe emotional dysregulation may still require DBT’s skills focus initially [Table 1].^[13]

Therapist expertise: CAT requires training in its specific tools (e.g., SDR, reformulation letters), so clinician competency is critical.^[40]

Contextual factors: In settings with fewer resources or shorter treatment windows, CAT’s structured brevity is a practical advantage. However, in cases requiring intensive, long-term support (e.g., severe BPD with self-harm), DBT may be more appropriate.^[13,42]

Future directions

Even though CAT is still an effective clinical intervention, some areas still need more study. First, more RCTs are required to provide higher-quality evidence across a variety of clinical conditions and populations. The methodological rigor of recent studies varies, despite the encouraging results; therefore, more research with larger sample sizes and more robust designs is required.^[45]

Examining how well CAT works in conjunction with other therapeutic modalities may demonstrate the benefits of integrative care. To treat patients with severe or chronic mental health disorders, for example, it may be helpful to look at how CAT interacts with medication or other psychotherapeutic approaches.^[48]

To guarantee CAT's worldwide applicability, its cultural adaptations must be further developed. Future research could examine cross-cultural comparisons to evaluate how changes to the therapeutic process improve results in various social contexts. The maintenance and advancement of clinical expertise ultimately depend on continuous training and supervision in CAT techniques. Integrating an evidence-grading system into clinical training programs will help clinicians make well-informed treatment decisions based on the best available research, as more empirical evidence becomes available.^[43,51]
