Suicidal behavior in patients with panic disorder: retrospective and prospective data

Area of Science:

• Psychiatry
• Clinical Psychology
• Epidemiology

Background:

• Anxiety disorders are prevalent and associated with significant morbidity.
• Suicidal behavior is a serious concern in patients with anxiety disorders.
• Understanding risk factors for suicidal behavior is crucial for effective intervention.

Purpose of the Study:

• To examine factors associated with suicidal behavior in patients diagnosed with panic disorder.
• To identify predictors of suicidal behavior in a prospective, longitudinal cohort.
• To elucidate the relationship between anxiety disorders, affective disorders, and suicidal behavior.

Main Methods:

• A naturalistic, prospective, longitudinal follow-up study (HARP) was conducted.
• 527 subjects with panic disorder (with or without agoraphobia) were analyzed.
• Data on past and prospective suicidal behavior, comorbid disorders, and onset of conditions were collected.

Main Results:

• 9% of subjects reported a history of suicidal behavior.
• Factors associated with suicidal behavior included depressive disorders, substance abuse, eating disorders, PTSD, and personality disorders.
• Early onset of the first anxiety or depressive disorder was also a significant risk factor.
• During the first 30 months of follow-up, 4.5% of subjects exhibited suicidal behavior.
• All prospectively recorded suicidal behavior occurred in subjects with comorbid depressive disorders.
• Suicidal behavior in panic disorder patients rarely occurred without affective disorders.
• Certain non-depressive disorders also substantially increased suicide attempt/gesture risks.

Conclusions:

• Depressive disorders are a primary correlate of suicidal behavior in panic disorder patients.
• Early onset of mental health conditions increases the risk of suicidal behavior.
• Effective suicide prevention strategies for panic disorder patients must address comorbid affective disorders.
