Grotjahn finds that group psychotherapy offers special advantages in a military setting because the soldiers are already conditioned to living in groups and because their special hostility to officers, including physicians, is mitigated by the group situation in which the individual soldier-patient feels more protected. Details of the sessions and suggestions as to their management are given. Grotjahn is of the opinion that such therapy gives the individual a feeling of confidence and emotional support in belonging to a group and provides opportunities for catharsis, development of insight and reintegration of personality patterns. Grotjahn concludes that group treatment has outgrown its character as an emergency measure and is growing into its own rights and functions within psychiatry.
