Large-group psychotherapy in a day treatment program

The potential for psychotherapy in a large-group format has been discussed since the 1960s. Day treatment programs provide optimal support for such groups. One program type, which has maintained large-group psychotherapy as a central feature for over twenty years, is described. Essential features include an integrated therapeutic team, with clearly defined leadership, that is open to examination of its own process. Such groups may not only provide effective therapy, but are also readily amenable for teaching and research in psychotherapy.
