  • Title: Non-suicidal self-injury in patients with eating disorders: prevalence, forms, functions, and body image correlates.
    Author: Pérez S, Marco JH, Cañabate M.
    Journal: Compr Psychiatry; 2018 Jul; 84():32-38. PubMed ID: 29679850.
    Abstract:
    INTRODUCTION: More than one third of patients with eating disorders report NSSI. Moreover, negative attitudes and feelings toward the body, body dissatisfaction, and body image disturbances have been linked to NSSI in community and clinical samples. However, there is a lack of studies exploring NSSI frequency and functions and the specific relationship between multidimensional body image dimensions and NSSI in eating disorder patients. OBJECTIVES: First, we explored the frequency, types, and functions of NSSI in a sample of 226 Spanish female participants with eating disorders (ED). Second, we explored differences in NSSI and body image depending on the ED restrictive-purgative subtype; and third, we explored differences in body dissatisfaction, body image orientation, and body investment in eating disorder patients without NSSI (n = 144), with NSSI in their lifetime (n = 19), and (b) with NSSI in the previous year (n = 63). RESULTS: Of the overall sample, 37.1% (n = 89) had a history of self-injury during their lifetime, and 27.1% (n = 65) had self-injured in the previous year. Among the types of ongoing NSSI, the most frequent were banging (64.6%) and cutting (56.9%). Restrictive vs purgative patients differed on NSSI lifetime, Appearance Evaluation, Body Areas Satisfaction, Body Protection and Feelings and Attitudes toward the Body. Moreover, significant differences were found on Appearance Evaluation, Body Areas Satisfaction, Positive Feelings and Attitudes towards the Body, Body Protection, and Comfort with physical contact, between participants without a history of self-injury and both NSSI groups. DISCUSSION: Body dissatisfaction and body investment have been found to be variables related to NSSI. Thus, the present study highlights the importance of working on body image in ED patients to reduce the frequency of NSSI.
