Understanding Sequential Diagrammatic Reformulations (SDRs) in CAT

CAT diagrams or SDRs are developed in the course of CAT therapy to guide therapists and clients on the therapy journey (Ryle, 2003). They are used to illustrate problem procedures and are referred to throughout the therapy to aid recognition and identify exits. SDRs are unique to CAT and central to the process of the therapy. However there is little research of clients’ experience of SDRs and no systematic research of therapists’ experience.

The aim of this research is to explore both clients’ and therapists ‘experience of using SDRs in CAT therapy. Clients and their therapists will be interviewed separately using semi-structured interview protocols. The data will be analysed using Interpretative Phenomenological Analysis (IPA, Smith, Flowers & Larkin, 2009) to explore the lived experience of the participants.

The intended sample size will be 3-6 therapist-client dyad pairs. The research will take place in the Psychotherapy Department and the South Hackney Community Mental Health Team in City and Hackney. The study is being conducted as Jessica Osborne’s thesis for her Doctorate in Clinical Psychology at Royal Holloway, University of London. It is being supervised by Maxine Sacks, Consultant Clinical Psychologist at the Hackney Psychotherapy Department and Michael Evangeli, Lecturer in Clinical Psychology, Royal Holloway University of London.

Data collection started in December 2010 and will be completed by July 2011.
