Axis I and axis II comorbidity in panic/agoraphobic patients with and without suicidal ideation.
In view of the controversial relationship between certain aspects of panic disorder with agoraphobia (PDA), suicidal ideation and comorbidity, the purposes of this study were to compare severity of PDA and Axis I and Axis II comorbidity in PDA patients with and without suicidal ideation, and to examine predictors of suicidal ideation in these patients. Eighty-eight consecutive outpatients with PDA were administered structured diagnostic interviews for the DSM-IV Axis I and Axis II disorders (SCID-I and SCID-II), while the severity of PDA was assessed by means of the Panic Disorder Severity Scale. Of the patients, 25 (28.4%) reported suicidal ideation in past years ('ideators'). The severity of PDA was greater among ideators, and they were significantly more likely to have a personality disorder and more than one comorbid Axis I and Axis II disorder. There were no ideators without either Axis I or Axis II comorbidity. Univariate logistic regression identified several predictors of suicidal ideation: any DSM-IV Cluster C personality disorder, any DSM-IV Cluster B personality disorder, any comorbid mood disorder, and severity of PDA. With multivariate logistic regression, a combination of any Cluster C personality disorder and severity of PDA emerged as the most significant predictor of suicidal ideation. These findings have implications for clinical practice in that PDA patients should be carefully assessed for the severity of their illness and presence of certain personality disorders and comorbid mood disorders, because they may all increase the risk for suicidal ideation.
