Emotional regulation appears to be a key factor in self-injury. But body image also may play an important role in self-harming.

Analysis of the relationship between non-suicidal self-injurious behavior and various aspects of body representation and body perception in adolescents and young women suffering from depression.

The study involved 85 women with endogenous depression. The answer to the question “Sometimes I purposely injure myself” was used as an indicator of self-harm. The methods include: SCL-90-R, Body Investment Scale (BIS), Physical Appearance Comparison Scale-Revised (PACS-R), Body Satisfaction Scale (BSS), Cambridge Depersonalization Scale (CDS).

The relationship between self-injurious behavior and emotional, cognitive and behavioral characteristics of the self-body perception was revealed: more negative body image - dissatisfaction with its parts and the whole body (correlation with BSS_head ,238*, BSS_body ,472**, BSS_total_score ,453**), which is accompanied by behavioral manifestations - reduced “Protection” (correlation with BIS -,281**), higher rates of self-surveillance and comparisons of the self-body with others (PACS-R ,323**), depersonalization (CDS ,301**), body dissociation (CDS ABE ,346**), somatization (SCL-90-R ,226*).

For young women with depression, it has been shown that when self-harming, the self-body is “devalued”, perceived as “bad,” and the need to protect it is ignored. The severity of self-harm directly correlates with the phenomena of somatopsychic depersonalization. The results obtained may indicate that rejection of the self-body, “alienated” attitude and deprivation of the body of “subjectivity” can contribute to its use as a tool for solving psychological problems, which is a risk factor for the development, consolidation and aggravation of self-injurious behavior.

The rubber hand illusion (RHI) has been widely used to investigate the bodily self in healthy individuals. The aim of the present study was to extend the use of the RHI to examine the bodily self in eating disorders (EDs).

The RHI and self-report measures of ED psychopathology [the Eating Disorder Inventory – 3 (EDI-3) subscales of Drive for Thinness, Bulimia, Body Dissatisfaction, Interoceptive Deficits, and Emotional Dysregulation; the 21-item Depression, Anxiety and Stress Scale (DASS-21); and the Self-Objectification Questionnaire (SOQ)] were administered to 78 individuals with an ED and 61 healthy controls.

Individuals with an ED experienced the RHI significantly more strongly than healthy controls on both perceptual (i.e. proprioceptive drift) and subjective (i.e. self-report questionnaire) measures. Furthermore, both the subjective experience of the RHI and associated proprioceptive biases were correlated with ED psychopathology. Approximately 23% of the variance for embodiment of the fake hand was accounted for by ED psychopathology, with interoceptive deficits and self-objectification significant predictors of embodiment.

These results indicate that the bodily self is more plastic in people with an ED. These findings may shed light on both aetiological and maintenance factors involved in EDs, particularly visual processing of the body, interoceptive deficits, and self-objectification.
