Symptomatic treatment of agoraphobia and social phobias: a follow-up study.
1. Twenty-six out of 28 out-patients with agoraphobia and social phobias who had originally been treated with phenelzine or placebo in a double-blind clinical trial were followed up for a mean period of one year. During the follow-up period patients received further pharmacotherapy or behaviour therapy, except that those patients originally receiving placebo were not allowed therapy with monoamine oxidase inhibitors. 2. Ratings of phobic and additional symptoms, social adjustment and degree of personality disorder were made after one year by one of the authors (D.S.) who had no prior knowledge of the treatment each patient had received. 3. There were no significant differences in any of the ratings between the patients of the two groups, but those originally receiving placebo had more additional treatment in the follow-up period. Patients continuing to receive phenelzine frequently experienced a return of symptoms if the drug was withdrawn before six months treatment had elapsed. 4. Degree of personality disorder showed a significant negative correlation (p = -0.6) with improvement in the phenelzine group but not in those receiving placebo originally. 5. Improvement in social adjustment items was less than improvement in symptoms at follow-up. The implications of this are discussed. 6. The results suggest that phenelzine is of comparable efficacy to other symptomatic treatments for agoraphobia and social phobias, but that it acts mainly by symptom suppression. Prolonged treatment in patients with personality disorders is not indicated, for improvement is less likely and the dangers of dependence are greater.
