Suicidality in panic disorder: a comparison with schizophrenic, depressed, and other anxiety disorder outpatients.
Recent findings by Weissman, Klerman, Markowitz, and Ouellette (1989) that subjects with panic disorder, with and without comorbid conditions, may be at increased risk for suicide attempts have been controversial. In an attempt to further investigate this finding, we utilized the original National Institute of Mental Health Epidemiological Catchment Area (ECA) suicide questions in an outpatient psychiatric clinic. We examined patients with panic disorder (n = 101). other anxiety disorders (n = 47), schizophrenia (n = 22). and major depression (n = 19). No significant differences were found among all four groups on any of the ECA suicide ideation questions. Only two (2%) of the panic disorder patients and none of the other groups made a suicide attempt in the past year. While 17% of patients with panic disorder and 9% of patients with other anxiety disorders reported having made a suicide attempt at some other time in their life, the schizophrenic (33%) and depressed groups (40%) reported significantly greater histories of suicide attempts. In a forward stepwise regression analysis for panic disorder patients, a history of substance abuse and comorbid depression predicted suicidality. The actual clinical risk for suicide attempts in panic disorder patients appears to occur when they suffer with comorbid diagnoses. These results highlight the need to aggressively treat panic disorder patients so they do not suffer the all-too-common sequelae of depression and substance abuse.
