This emphasis on the therapeutic relationship and the mutual influence between the therapist and the patient is a central tenet of relational psychoanalysis, which emerged as a distinct school of thought in the 1980s and 1990s. Relational psychoanalysis also emphasizes the importance of the therapist's subjectivity and personal history and how these factors can influence the therapeutic process.
Thus, while Guntrip did not explicitly use the term "relational psychoanalysis," his work on personal relations therapy foreshadowed many of the key ideas that would later become central to this school of thought.
