Mediating Factors between Childhood Traumatic Experiences and Eating Disorders Development: A Systematic Review

Abstract

Background: Many people with eating disorders often report having suffered some kind of childhood trauma. For this reason, many studies have attempted to explore the mediating factors between traumatic experiences and the development of eating disorders. The aim of our study is to conduct a systematic review of published works on the mediating factors between childhood trauma and the development of eating disorders. Method: This review was carried out up to 5 December, 2020, using the databases PsycInfo and PubMed, combining the keywords, and applying a set of inclusion and exclusion criteria. Results: A total of 18 articles were retrieved. After the articles were analyzed, a set of mediating factors between childhood trauma and the development of eating disorders was established, including pathological dissociation, difficulty with emotion self-regulation, body dissatisfaction, negative affect/depression, anxiety, general distress, self-criticism, and alexithymia, among others. Conclusions: In addition to evaluating trauma in eating disorders, these results highlight the importance of paying special attention to the presence of various possible mediating factors, which must be taken into account in the planning of therapeutic treatment. Identifying symptoms of trauma or eating disorders early on could prevent onset of more severe psychopathology during adulthood.
