Treatment of insomnia using a variant of systematic desensitization: a case report.

This report describes the treatment of a case of severe insomnia. The treatment, a variant of systematic desensitization, was short and apparently quite successful. The primary difference between usual desensitization procedures and those employed in this case was the absence of a fear hierarchy. A trainee-observer was present during several training and early therapy sessions. He observed 2 therapy sessions and then became the therapist. He was directly supervised for 2 more therapy sessions and then continued treatment singly. The case illustrates the flexibility of behavior therapy in both procedural variations and in training of therapists.
