The authors introduced group conferences on sex as part of the ward routine on the Adolescent Ward of Bellevue Psychiatric Hospital. The number in a group was fixed at five and consist of a mental defective, an epileptic or psychotic, and three nonpsychotic and nondefective delinquents. The patients are carefully interviewed individually before the group is constituted. A verbatim excerpt of a typical group conference is presented which demonstrates the topics discussed, the use of popular terminology and the encouragement of the participants by the leader.
