During the last few years at the Hampstead Clinic we have studied a small number of children who had at the time of their diagnostic assessment or previously had an imaginary companion. In no case was the imaginary companion the cause for referral. Usually, its existence was elicited more or less accidentally during the course of the diagnostic investigation.
In collaboration with Alice Colonna and the Clinical Concept Research Group whose members are: H. Nagera (Chairman), A. Freud (Consultant), S. Baker, A. Colonna, R. Edgcumbe, M. Foote, W. E.

I wish to thank Eva Bry, Lottie Kearney, Elizabeth Model, Dr. Josephine Stross, and T. de Vries.

1 Bender and Vogel (1941) have described a large number of children mostly in latency and late latency who talked quite freely of their imaginary companions in a therapeutic situation. But these children were not in analysis (with its special setting and conditions); they were studied in hospitals where they seem to have been very actively questioned.
