Group-analytic diagnosis was explored in the following paper. In the training field, the writing of this paper resulted from collaboration between teachers and postgraduates of the COIRAG Postgraduate School, in Rome. In particular, a paper’s excerpt was submitted by some students at the seminar entitled “The field of diagnosis: personality, family and context”, held by Vittorio Lingiardi and Nancy McWilliams. A case illustration has been described, exemplifying a way of observing the diagnostic process and constructing the therapeutic project, within the group-analytic field. So the authors focused on some process diagnostic variables, such as the relationship between identification and identity, family network and social network, “co-transfert”, dream work, the institutional level. For the authors, the analytic diagnosis of the patient involves careful observation of both the intrapsychic world of patient and therapist and the interpersonal and social context. This way of approaching the diagnostic process is very present in the research project carried out over the years by the seminar speakers, which led to the writing of the PDM. Some connections between the psychodynamic setting of PDM and the group-analytic one will be proposed.
