This is a collection of essays presenting six different models and treatment programs for agoraphobia. All the authors agree that exposure (placing the patient in the phobic situation) is an important part of treatment, though they disagree about the degree and manner of doing so. But exposure seems insufficient, since, despite data indicating improvement, “notable residual disability is the rule.” There is no agreement among the authors that augmented treatment produces better results, except in the case of pharmacotherapy, and there is a question of relapse rates in that case. It is suggested that the problem may be whether agoraphobia is focused upon in isolation or in relation to other neurotic symptoms, and, if the latter, how independently they each operate and respond to treatment. The editors think that it may be the case that there are two types of agoraphobia, in one of which the “agoraphobic symptoms are thought to be maintained by their relevance to intrapsychic or interpersonal needs” and that additional psychotherapy need be provided only for the latter group.
