Background:

Through the culture of thinness, increasingly promoted in our society as a beauty canon, it is not surprising that the number of people affected by eating disorders is increasing.

Objective:

This research aims to study the relationship between non-suicidal self-injuries and nuclear aspects of eating disorders specified along with this article.

Methods:

The sample consisted of 60 women diagnosed with anorexia and bulimia. Questionnaires assessing impulsivity, body satisfaction, alexithymia, body attitude and self-esteem were administered. Participants with non-suicidal self-harm were compared with those without it, and participants with anorexia with and without self-harm and participants with bulimia with and without self-harm were compared.

Results:

Differences were found in body dissatisfaction= 5.71; p ≤0.01), body attitudes= 4.80; p ≤0.02), self-esteem= 14.09; p ≤0.00) and impulsivity (t= 3.39; p ≤0.01) between participants with and without non-suicidal self-harm.

Conclusions:

These are key factors for the clinical area in the treatment of eating disorders to prevent the presence of self-harm, as it allows focusing the treatment target on those aspects such as dissatisfaction and impulsivity, which are key in the development of self-harm.
