Abstract
The authors' goals were to examine predictors of suicidal behavior and provide guidelines for assessing suicide risk in patients with panic disorder. Four hundred ninety-eight patients with panic disorder were followed for 5 years. Survival analysis was used to examine variables correlated with prospectively observed suicidal behavior. Subjects had a 0.06 probability of suicidal behavior during follow-up. Affective disorders, substance abuse, eating disorders, personality disorders, and being female were risk factors. Two subjects were suicidal in the absence of risk factors; both developed depression during follow-up. Panic disorder is not associated with suicidal behavior in the absence of other risk factors.
