Comorbidities of Nonsuicidal Self Injury (A Literature Review Study)

Abstract
The growing prevalence and high risk of self-harming behaviour is drawing the increased attention of experts to this unwanted phenomenon. As a result, efforts are also being made to include self-harm among clinical diagnoses in the Diagnostic and Statistical Manual of Mental Disorders, in which the American Psychiatric Association, in the fifth revision (DSM-5), presents the concept of “Nonsuicidal Self-Injury” in the section Conditions for Further Study. However, in order to establish this nosological unit in the classification system of mental disorders, research is still needed in several areas – one of which is the area of comorbidities of self-harm. Knowledge of the comorbidities of self-harm is needed not only to supplement the basic data on the diagnosis, but also for the overall understanding, effective treatment and prevention of this unwanted phenomenon. The presented study focuses on mapping the occurrence and frequency of comorbidities of “Nonsuicidal Self-Injury” in the scientific literature published over the last 10 years. Publications were retrieved from the Scopus database using the search phrases: “NSSI” & “comorbidit*” and: “self-injur*” & “comorbidit*”. After using the inclusion criteria (A/ scientific studies, B/ published in the last 10 years, C/ in the field of social sciences, health, and humanities, D/ in English, E/ with open access access), 80 scientific sources were acquired. Then, after studying the content of the articles, a further 26 publications were excluded (11 for being out of scope and 15 due to insufficient data). The resulting analysis of comorbidities of Nonsuicidal Self-Injury was carried out using 54 scientific publications, 46% (N=25) of which reported Depressive Disorders as a comorbidity, 38.9% (N=21) Anxiety Disorders and 33.3% (N=18) Feeding and Eating Disorders. An important finding is the high incidence of Suicidal Behaviour (27.8%, N=15), which supports the inclusion of self-harm among the high-risk forms of behaviour and also contributes to the topicality of ongoing discussions about whether suicidal behaviour has a place in self-harm or should be explicitly excluded from it, as proposed by DSM-5.
