Anxiety in Major Depression: Relationship to Suicide Attempts

Abstract

OBJECTIVE: This study was an examination of the relationship of lifetime panic disorder and anxiety symptoms at index hospitalization to a history of a suicide attempt in patients with a major depressive episode. METHOD: A total of 272 inpatients with at least one major depressive episode, with or without a history of a suicide attempt, were entered into the study. They were given structured diagnostic interviews for axis I and axis II disorders. Suicide attempt history, current psychopathology, and traits of aggression and impulsivity were also assessed. RESULTS: The rates of panic disorder did not differ in the suicide attempters and nonattempters. Agitation, psychic anxiety, and hypochondriasis were more severe in the nonattempter group. A multivariate analysis confirmed that this effect was independent of aggression and impulsivity. CONCLUSIONS: Comorbid panic disorder in patients with major depression does not seem to increase the risk for lifetime suicide attempt. The presence of greater anxiety in the nonattempters warrants further investigation.
