Dynamic Patterns in the Voices of a Patient Diagnosed with Borderline Personality Disorder, and the Therapist throughout Long-Term Psychotherapy

This is the authors' abstract. We don't add key points for this paper.

This case study identified the subjective change in a patient diagnosed with Borderline Personality Disorder (BPD) by analyzing the dynamic patterns that emerged during discursive interaction with her therapist during a successful long-term psychotherapy. A qualitative analysis was conducted by applying the Model of Analysis of Discursive Positioning in Psychotherapy (MAPP), tracking voices and the personal positions of the patient and therapist in all sessions. Subsequently, dynamic patterns were identified and the hypothetical attractors were defined (i.e., the most stable patterns in the interaction of voices) using the Space State Grid (SSG) technique. Five sessions (representing the initial, middle and final stages) were selected to describe the trajectory of the patient’s subjective change. These sessions highlight the presence of different attractors and depict the intersubjective interaction that developed during the process. The results suggest a process of subjective transformation from a monological to a dialogical dimension, a change supported by therapeutic interaction based on propositional and reflective discursive aspects; a transition from a state of dissociation of the patient to a reorganization of her subjectivity. The most relevant characteristics of this process as an emergent quality of psychotherapy and its relation to the patient’s positive outcomes are discussed.
