Introduction
The risk of suicide may be elevated in the presence of personality pathology. Adults with Obsessive Compulsive Personality Disorder (OCPD) may be vulnerable to depression and suicidal thoughts.
Objectives
To identify factors associated with suicide in cases of OCPD.
Methods
Psychological autopsy procedures were used to gather detailed information about adults who died by suicide and natural causes. A total of 75 deceased adults were evaluated using psychological autopsy procedures. Family members were interviewed about a recently deceased adult, using structured diagnostic interviews (SCID and SIDP-IV). Diagnostic summaries, coroner’s reports and police records were reviewed by a psychiatrist, a psychologist, a social worker, and a neuroscientist until agreement was reached about final diagnosis. The final sample included 40 adults who met criteria for OCPD (18 had died by suicide; 20 had died by natural causes). An additional 40 cases were examined in which evidence of PD was absent (19 had died by suicide; 18 had died by natural causes).
ResultsComparison of four groups using psychological autopsy procedures to identify the presence of diagnostic criteria for a Major Depressive Episode at the time of death.
The diagnosis of a Major Depressive Disorder was significantly more common in suicide completers with OCPD compared to suicide completers without OCPD (X2 = 6.74, p < .01) or cases of natural death with OCPD (X2 = 12.70, p < .001). Suicide completers with OCPD displayed many symptoms of depression, more often than suicide completers without OCPD or cases of natural death with OCPD (see Table 1). As compared to the cases of natural death, both groups of suicide completers were more likely to have previously attempted suicide prior to their final act (X2 = 8.52, p < .05).Table 1.

Conclusions
Adults with OCPD appear vulnerable to a Major Depressive episode, and the combination of MDD with OCPD creates a significant risk for death by suicide. It is important to appreciate the influence of personality disorder or depression and suicide risk.
