Case formulations in mentalization-based group therapy.

Ideally, the assessment phase of patients who are referred to mentalization-based treatment (MBT) should conclude with a mentalization- based case formulation. The structure and content of such case formulations are described. Their aim are: i) to enhance treatment alliance and ii) to provide some structure to the treatment process through suggesting privileged themes related to emotions, relational patterns and mentalizing. MBT is a conjoint kind of psychotherapy, integrating individual and group therapies. Case formulations has belonged to the tradition of individual psychotherapy, while being mostly ignored by group therapists. The question is: are case formulations also relevant for group psychotherapy? How can they be properly introduced while not disturbing the group processes? The theme is discussed through a clinical vignette that illuminates typical therapeutic challenges in dynamic group psychotherapy with borderline patients. The author concludes with some suggestions for clinical structure, process and research.
