Dissociative symptoms in panic disorder

The present study examined the prevalence and correlates of dissociative symptoms in patients with panic disorder and patients with other nonpanic anxiety disorders. A total of 56 patients with anxiety disorders (13 with panic disorder alone, 16 with comorbid panic and other anxiety, and 27 with other anxiety disorders) were assessed with structured clinical interviews and a battery of questionnaires. Although 69% of patients with panic disorder experienced depersonalization or derealization during their panic attacks, panic disorder patients were no more likely to experience dissociative experiences as assessed by the Dissociative Experience Scale than patients with other anxiety disorders. In the entire sample, the prevalence of dissociative experiences was very low and well within nonpathological ranges. The correlates of dissociative symptoms were severity of depression, social anxiety, and personality disorders. The implications of these findings for conceptualizing the nature of dissociative symptoms within an anxiety population are discussed.
