Psychiatric and personality disorders in deliberate self-harm patients

Abstract

Previous UK studies have reported much lower rates of psychiatric and personality disorder in those who attempt suicide than in those who die by suicide. To determine the nature and prevalence of psychiatric and personality disorders in deliberate self-harm (DSH) patients. A representative sample of 150 DSH patients who presented to a general hospital were assessed using a structured clinical interview and a standardised instrument. Follow-up interviews were completed for 118 patients approximately 12-16 months later. ICD-10 psychiatric disorders were diagnosed in 138 patients (92.0%), with comorbidity of psychiatric disorders in 46.7%. The most common diagnosis was affective disorder (72.0%). Personality disorder was identified in 45.9% of patients interviewed at follow-up. Comorbidity of psychiatric and personality disorder was present in 44.1%. Psychiatric and personality disorders, and their comorbidity, are common in DSH patients. This has important implications for assessment and management.
