The author postulates that theoretical explanations of the etiology of
anger and aggression inform the group therapist's interventions. Four
psychodynamic schools of thought-drive theory, ego psychology, object
relations theory, and self psychology-are discussed. Choice of the be
st-suited theory to increase understanding may vary according to the p
articular patient and/or set of group circumstances. A pitfall to be a
voided is forcing any given individual, event, Or process into a speci
fic school of thought. In the group, special issues related to anger e
xist: the therapist's vulnerability to narcissistic injury if made the
focus of anger, the increased intensity and force of anger that can b
e mustered in a group, and the safety afforded patients as they, outnu
mbering the therapist(s), express anger.
