Research & Evaluation

Catalyse is committed to research and evaluation of cognitive analytic therapy and has supported a number of initiatives and projects. Several people within Catalyse are research-active and have contributed to the evidence base for cognitive analytic therapy. Dr Stephen Kellett , Professor Glenys Parry and Dr Dawn Bennett  have been particularly involved in CAT research, both in the past and more recently. You can see a selection of their publications on their profile pages.

Glenys and Dawn co-developed the CCAT measure to help rate therapist competence in cognitive analytic therapy. You can download a copy of the CCAT by clicking on this link.

You can commission experienced researchers within Catalyse to

  • support or develop small or large-scale projects,
  • offer advice on project evaluation, or
  • provide routine service audit.

Recent examples of research carried out by Catalyse Associates include:

CAT Case Management Evaluation

We conducted an evaluation of a CAT Case Management approach being used within the Big Lottery funded Liverpool Waves of Hope project led by Plus Dane HousingThis project supported people with multiple and complex needs.  Dr Karen Shannon and Professor Glenys Parry presented results of this evaluation at the Society for Psychotherapy Research (SPR) conference in September 2017.


We supported research carried out by Sheffield University on developing and trialling a new CAT App. Our Sheffield Psychotherapy Practice (active until 2021) helped to field test the App. We are exploring means for further trials with NHS and private therapy providers. Two publications summarise progress to date:

  • Kellett S, Easton K, Cooper M, Millings A, Simmonds-Buckley M, Parry G (2020) Evaluation of a Mobile App to Enhance Relational Awareness and Change During Cognitive Analytic Therapy: Mixed Methods Case Series. JMIR Ment Health 2020;7(12):e19888
  • Easton K, Kellett S, Cooper M, Millings A, Varela J, Parry G (2021) Blending Cognitive Analytic Therapy With a Digital Support Tool: Mixed Methods Study Involving a User-Centered Design of a Prototype App. JMIR Ment Health 2021;8(2):e20213

CAT Competence Framework

Dawn Bennett, Stephen Kellett and Glenys Parry collaborated with Tony Roth of University College London in developing a Competence Framework in Cognitive Analytic Therapy, with the support of ACAT. You can read a paper about its development at:

  • Parry, G., Bennett, D., Roth, A. D., & Kellett, S. (2021). Developing a competence framework for cognitive analytic therapy. Psychology and Psychotherapy: Theory, Research and Practice.

LYMCA Staff Training Evaluation

Dawn Bennett, Stephen Kellett and Glenys Parry undertook an evaluation of the impact of CAT skills training within services for people with multiple and complex needs provided by YMCA Liverpool and Sefton (now YMCA Together).

Support for research

Part of our mission as a not-for-profit social enterprise is to support research on cognitive analytic therapy undertaken by academic staff in Universities or the NHS. In addition to research we have undertaken, we have financially contributed to these projects:

  • Peter J Taylor et al : What are the key elements of cognitive analytic therapy for psychosis? A Delphi study.
  • Stephen Kellett & Jaime Delgadillo: Cognitive-behavioural versus Cognitive-analytic guided self-help for anxiety; a patient preference clinical trial.
  • Stephen Kellett: The effectiveness of Personal Reformulations during the training to become a Clinical Associate Psychologist (CAP).

Other initiatives

We collaborated with ACAT in offering two joint research conferences:

Encouraging to Engaged – A One Day Conference for CAT Practitioners in April 2018, and

The Research Journey From Start to Finish – Motivating-to-Motivated in March 2019.

These events brought together a host of active CAT researchers to share their work with others in the CAT community. They provided opportunities for participants to build skills and confidence in research. Alison Jenaway (ACAT chair at the time) wrote a blog reflecting on the first joint research conference: read Alison’s blog here.
