Cluster C Personality Disorders in Major Depressive Episodes: The Relationship Between Hostility and Suicidal Behavior

Abstract

There is some evidence for an association between Cluster C Personality Disorders (CCPD) and suicidal behavior. We compared depressed inpatients with and without CCPD in terms of suicidal behavior and associated psychopathology. Cluster A or B personality disorder co-morbidity were exclusion criteria for both groups (cases and controls). Depressed inpatients with “pure” CCPD had higher levels of suicidal ideation but not more previous suicide attempts compared with patients without CCPD. Greater suicidal ideation in depressed patients with CCPD in our study was associated with more hostility. Future studies examining the relationship between suicidal ideation and hostility in CCPD may clarify whether treatment focused on hostility might be of use for decreasing suicidal ideation in depressed patients with CCPD (Spitzer, Williams, Gibbon et al., 1990).
