The development of the multiple self states model

Abstract

Abstract The chapter introduces the multiple self states model (MSSM) and describes its elaboration alongside developments in mapping and sequential diagrammatic reformulation (SDRs). It examines early applications of the model to working with people with complex emotional and interpersonal problems and the role of early trauma and dissociation in the development of complex health problems. Reference is made to research studies examining the efficacy of the model with a range of different clinical presentations. The chapter describes cognitive analytic therapy (CAT) concepts of states, self states, state shifts, and metaprocedures and the central role of partial dissociation in many of the difficulties experienced by people with diagnoses of personality disorder, such as borderline and narcissistic personality disorder. It explores different kinds of state shift and the view of the self as comprising a multiplicity of different aspects, selves, or voices. It goes on to highlight the usefulness of CAT tools, such as sequential self state diagrams (SSSDs), the personality structure questionnaire (PSQ), and the state description procedure (SDP) and their application is further explored through a clinical case vignette. The vignette also describes processes of engagement in the therapy, use of the therapeutic relationship and countertransference, mapping and the importance of developing awareness of state shifts and their triggers. Finally, the chapter looks at the application of the model to team work and the reformulation of team processes through contextual reformulation.
