This case study focuses on the therapeutic change process, highlighting the crucial role of therapists in facilitating it. Rooted in constructivist epistemology, we employed an integrative systemic model. Our exploration centers on the presence or absence of system restructuring within the therapeutic process. We delve into the differing perceptions of change between the therapist and the client, particularly regarding the criteria for therapy discharge. A significant aspect of our analysis is the discussion on the authenticity of change. We examine the dual role of therapists as expert observers and participants in the therapy, navigating between "objective" and subjective perspectives in their interventions. This includes assessing various levels of change, first and second order. We highlight the client's autonomy in defining the reality and authenticity of change, advocating for a balance between the therapist's guidance and the client's agency. Additionally, we emphasize the therapist's need for self-reflection and adherence to ethical practices. Our study contributes to systemic therapy literature by demonstrating the effective application of an integrative approach. It reinforces the importance of collaboration in therapeutic change, offering insights into how therapists can navigate complex therapeutic dynamics.
