Psychiatric and personality disorders in deliberate self-harm patients
Background:
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.
Aims:
To determine the nature and prevalence of psychiatric and personality disorders in deliberate self-harm (DSH) patients.
Method:
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.
Results:
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%.
Conclusions:
Psychiatric and personality disorders, and their comorbidity, are common in DSH patients. This has important implications for assessment and management.
