A group analyst has an enormous influence over the group dynamics (the ‘matrix’) and this derives from his or her ‘identity or group analytic attitude’ which has been developed through training, practice and group analytic supervision. Each group analyst must develop personal attributes and also affective/cognitive capabilities required to become a ‘good enough group analyst’. Throughout group therapy sessions, specific dimensions appear related to each group analyst. These are of particular importance for a good evolution of group processes, pertaining to his ‘presence’ face-to-face with the group and to his personal ‘style’.
