Defining and Refining Self-Harm: A Historical Perspective on Nonsuicidal Self-InjuryAngelotta, Cara MDJournal of Nervous & Mental Disease: February 2015 - Volume 203 - Issue 2 - p 75–80 doi: 10.1097/NMD.0000000000000243 Original Articles Abstract Author Information Abstract: Nonsuicidal self-injury (NSSI) is a newly proposed diagnostic category in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Some contemporary historiography dismisses NSSI as a fiction of modern psychiatry. Although the exact definition and psychological meaning attributed to self-harm has not been static over history, there is a clear thread that connects Western asylum psychiatrists’ thinking about self-harm to the current stand-alone diagnostic category of NSSI. Nineteenth-century psychiatrists identified a clinically meaningful difference between self-harm with and without the intent to die, between self-injurers who were psychotic and those who were not, and between self-injurers who made a single, serious mutilation and those who repetitively self-injured without causing permanent bodily damage. These same distinctions are apparent in the definition of NSSI. Thus, NSSI is a formalization of long-held observations about a category of people who repetitively self-injure without suicidal intent.
