Book excerpt: Change Through Time in Psychoanalysis presents a new stage of the work done through the IPA Committee on Clinical Observation between 2014 and 2020—the advances in our method, the Three Level Model (3-LM), and our clinical thinking. In this new volume, ideas on observational research, clinical narratives based on 3-LM group discussions, and adaptations of the model for training candidates show more experience, more depth, more answers, and, of course, new questions. Contributors from three regions of the IPA have written extended case studies of 10 psychoanalyses, rich in verbatim session material, focusing on the main dimensions of the patient’s psychic functioning, specific changes in the analytic process, and related interventional strategies. The reader will find, in the method and in the clinical narratives, new and clarifying points of view in the observation of transformations in patients in psychoanalysis and of the analysts’ techniques, useful both in professional development and in teaching candidates.
