Rather than use the term therapist personality, the author uses an operational definition of countertransference to examine the intersubjective field between group therapist and individual patients, the group, and subgroups. Differentiating between objective and subjective countertransferences, the author traces their sources to the transferences and resistances that arise from individuals, subgroups, and the group-as-a-whole. The transferences, resistances, and their related countertransferences are then integrated with enactments and history to create interventions. The charismatic leader makes no differentiation between the countertransferences and primarily acts on impulse or a rigid system.
