CAT in Forensic Services

In this article, Jamie Kirkland, Karen Shannon and Andrea Daykin povide an overview of how applications of Cognitive Analytic Therapy have developed in the forensic field.

People who find themselves in the criminal justice system commonly experience high levels of distress, mental health, trauma and complex interpersonal difficulties/personality disturbance (Pollock, P et al 1994) and risk potential (Shannon, K 2009) There is a need to provide interventions aimed to reduce distress for clients by addressing their clinical problems in addition to the prevention of offending behaviour.

Popular culture is fascinated by crime, though it often takes the perspective of the victim and the investigators. As therapists we are presented with the person, or system, in front of us.

Turning our sights to the "criminal", the Oscar winning film ‘Joker’ invited the audience to understand the backstory of the ‘evil’ Joker, Arthur Fleck. This was to make sense of his violence by looking at early trauma that shaped him. I think this is why the film moved me so much (JK). Much of my work is making sense of the early tragedies that shape future behaviour.

The helping professions try to ‘help’. However, in forensic services the first duty is public protection; not to the client or offender. But it's not really possible to engage in a therapeutic way with someone who has offended without engaging on a more human level.  To work in a world of ‘unspeakable acts', the forensic profession must understand the back story.  This enables us to build an empathic connection with the offender. We need to do this to work alongside the person and avoid that judging, critical, perhaps even, disgusted stance. We have to seek humanity in sometimes inhumane behaviour.

In this process, the work involves many aspects of that person’s life. But because of the consequences of such offending behaviour our work tends to include many more groups, systems, and voices. There is a risk that the forensic practitioner can become overwhelmed by all of these voices and the many eyes upon an offender. We find ways to address and work with this in our own practice, but in turn we may be called upon to support overwhelmed systems.

CAT helps enormously in this process. This relational model has developed over many years, expanding across more and more areas of our understanding of human behaviour. It provides an understanding of the self, but also the wider world. Writers who practice CAT have continued to extend its reach, offering glimpses of how it can be applied.

Books about CAT in a forensic setting

Three main texts have been published about CAT in forensic services:

Pollock & Stowell-Smith (2006) Cognitive Analytic Therapy for Offenders: A New Approach to Forensic Psychotherapy

Marshall & Kirkland (2021) Reflective Practice in Forensic Settings: A Cognitive Analytic Approach to Developing Shared Thinking

and most recently

Marshall & Kirkland (2024) Innovative Practice in Forensic Settings: A Cognitive Analytic Approach to Effective Relational Work

Forensic context

Providing CAT therapy to clients in forensic services, clinicians face the challenges of aiming to ensure both public protection, and to also assist offenders with reduction of risk potential. This is often referred to as the ‘the dual relationship problem’.

CAT therapists are therefore subject to wider systemic pressures of political, judicial, media and public scrutiny. These high demands raise frequent moral and ethical issues and systemic re-enactments that impact on therapeutic work. 

Use of CAT in a range of forensic settings 

CAT as a therapy has become increasingly recognised across the full range of forensic settings and security levels, including:

There has been development of innovative, diverse practice in CAT across disorders, offence type and age ranges, involving adaptations for different individual and group formats and cognitive limitations.

How CAT understands and manages offending behaviour

People who break the law usually have a positive aim. They are attempting to secure some kind of valued outcome in their lives. However they experience a range of limitations in themselves and their environments which prevent them from getting their needs met. Individuals therefore resort to offending; damaging and antisocial ways in attempt to meet their needs (Shannon, K 2009

As therapists we want to understand how earlier traumatic experiences have shaped clients’ ways of relating, and how these experiences are internalised and result in difficulties such as:

  • fluctuating levels of dissociation and reflective abilities

  • limited problem solving

  • difficulties regulating their emotions and behaviours, and

  • problems navigating relationships with themselves and others 

We aim to work alongside individuals, some of whom have been victims of harm, and who are also perpetrators of harm to themselves and others. As such they can occupy both positions of a reciprocal role e.g. abusing (perpetrator) to abused (victim).

How can CAT help?

What sort of offending behaviours have benefitted from CAT interventions?

CAT can help a diverse range of offending behaviours , including:

  • fraud/ deception,
  • burglary,
  • criminal damage,
  • fire-setting,
  • domestic abuse and coercive control,
  • stalking,
  • terrorism and
  • varying levels of severity of violent and sexual offences.
  • varying levels of severity of violent and sexual offences eg see (Mitzman, S 2010, Manson, K et al 2017

How long does CAT therapy last?

CAT therapy can be time limited (Carradice, A 2013) or 16-24 sessions to address clinical problems and offending behaviour (paper). However, the focus and pace of therapy will be determined by the individual’s zone of proximal development (ZPD) and there may be a need for preparatory or ‘pre-CAT' work’ focussed on engagement (Shannon, K 2016).

Families in addition to individuals 

Families can also benefit from applications of cognitive analytic therapy e.g. 

  • with non-abusing partners to help supervise and protect children from sexual harm (Shannon, K et al 2012)
  • work with parents to understand how their own early experiences, and that of their parents’ development experiences, impact on their parenting ability; and 
  • working with parents and services with children who engage in sexual and other harmful behaviours

Concurrent problems and integration of approaches

CAT therapy also focuses on co-presenting issues such as substance misuse or psychosis Morgan, S 2018 CAT can accommodate and complement other therapies and ways of working while being used as an overarching model, to also guide and integrate forensic services (Annesley, P et al 2012,  Brown, R. et al 2024 a and b)

CAT in risk assessment

At the heart of forensic services is effective risk assessment. CAT provides an opportunity for a collaborative and relational risk assessment incorporating CAT formulation in risk assessment and management plans. This can help inform management plans at both an individual and systemic level Shannon, K 2009  Mitzman, S 2010, Darajee, R et al 2024, Kirkland, J et al 2024). 

Criminal justice settings often involve multiple agencies and the voices of professionals and agencies working with the client can predominate in risk assessments .  A CAT-informed risk assessment ensures that the voice of the client has more representation in this process. (Kirkland 2015). 

We can use the principles from CAT in a versatile range of ways. 

Indirect use of CAT in forensic settings:

As well as working directly with clients, the CAT model can be applied in reflective practice with staff teams (see chapter: Marshall, Yorke et al, 2021).

It can be used as a consultative, case management or supervision tool for professionals who are working directly with clients. For example, the 5 Session CAT care planning approach involves time limited sessions with the client, keyworker and therapist. This approach has been adapted for use on the Offender Personality Disorder Pathways (see chapter: Daykin & Ryan, 2024). 

CAT and Team working 

Forensically orientated introductory CAT training has been used to relationally inform a whole clinical workforce of a forensic service, alongside provision of individual psychotherapy by CAT practitioners and CAT informed multidisciplinary risk formulation (Ramm 2010).

Organisational working 

CAT has been developed and utilised as an organisational framework in non-mental health/non=forensic settings e.g. homeless services and women’s refuges, and for people who are involved with the criminal justice system. Innovative use of CAT has developed trauma-informed and psychologically-informed environments.  This has been achieved via: the formation of relational organisational and service strategies, conflict management, human resources policy and procedures. This approach involves providing CAT training and reflective practice at all levels from Directors, senior managers, support staff and case management for staff and clients Shannon, K et al 2017,Shannon, K et al 2016

A whole system approach was attempted within a forensic service with CAT being used as a primary driver (Marshall & Kirkland, 2021)

Importance of personal therapy and supervision 

Working with clients' experiences of trauma, harm from others, extreme distress and survival can provoke difficult emotions and may elicit vicarious trauma for therapists and other professionals working in this field.

CAT Therapists receive CAT therapy as a key part of their training. This and ongoing reflection and supervision are necessary for working effectively in forensic settings. The provision of the safe, containing space, to normalise feelings elicited, actively reflect on them, is key to limiting the experience of distress or isolation for therapists, and importantly to inform formulated interventions for clients. 

In turn CAT therapists often provide supervision and support to other staff working in this area.

What research is there to demonstrate CAT’s effectiveness as a therapy in forensic settings?

Limited research exists on CAT in forensic settings. Published studies often reflect case study examples.  These are valuable, but the field would benefit from further research.

Connecting around CAT in forensic settings

If you  work in the forensic field and are interested in making links with others using CAT in this area, then there is a  CAT and Forensic Services Special Interest Group (SIG) .  This is open to open to all those working in forensic services, from CAT practitioners to those interested in learning about the model. You do not have to be an ACAT member to join this group. For more information go to the dedicated page listing ACAT's Special Interest Groups.
