Interpersonal stressors in individuals with personality disorders who die by suicide

Objective: To explore the characteristics and prevalence of interpersonal stressors prior to suicide in individuals with personality disorders compared to individuals without personality disorders.Methods: Records at the Office of the Chief Coroner of Ontario were reviewed to identify suicide decedents with personality disorders (n = 105) and without personality disorders (n = 5183) in Toronto, Ontario (1998Ontario ( -2020)).Coroner charts were coded for demographic data, interpersonal stressors, mental health history, and other suicide-related characteristics.Chi-square comparisons were conducted to examine stressors, and all other suicide-related characteristics associated with suicide across both groups.Results: Suicide decedents with personality disorders (M = 38.4 years 14.6, 48% female, 90.5% single) had higher interpersonal conflict than those without personality disorders (OR: 1.72, 95% CI [1.09-2.71]).Other interpersonal stressors, including a recent relationship breakup were not different between groups.Additional analyses showed that the personality disorder group was younger, and had a greater proportion of females, single individuals, and those with previous suicide attempts.Conclusion: Our results demonstrated that those with personality disorders had a higher prevalence of interpersonal conflict, but not other interpersonal stressors prior to suicide compared to those without personality disorders.Suicide decedents with personality disorders were primarily in low-risk demographic groups (i.e., females and younger people).
