Thirty-four patients meeting the DSM-III-R criteria for social phobia participated in a study on the relationship between per sonality disorder, symptom pattern, and treatment outcome. Eight patients (23.5%) were diagnosed with a personality disor der; 26 patients did not receive an Axis II diagnosis. Half of both groups received either an integrated treatment (rational emotive therapy, social skills training, and exposure in vivo ) or exposure in vivo alone. Conclusions are that patients with a personality disorder have more serious symptoms compared to patients without a personality disorder, but benefit equally from the treatments offered.
