According to the trans-diagnostic perspective, disturbances in eating patterns of eating disorders (EDs) are considered as epiphenomena secondary to the patient's overvaluation of his/her body shape and weight.

The phenomenological theory states that the main feature of ED psychopathology is a disturbance in the way affected persons experience their own body (embodiment). Insecure attachment may promote the development of unstable self-identity leading to use body weight as a source of self-definition.

The aim of our study was to assess the role of embodiment impairments in the relationships between attachment stiles and ED psychopathology.

One hundred twelve ED patients and 108 healthy subjects filled in the Identity and Eating Disorders (IDEA) questionnaire, which assesses embodiment and personal identity abnormalities, the eating disorder inventory-2 (EDI-2) and the experiences in close relationships (ECR) scale, which defines attachment styles.

ED patients showed IDEA, EDI-2 and ECR scores significantly higher than controls. Significant correlations between IDEA scores, insecure attachment and almost all EDI-2 sub-item scores emerged in ED patients but not in controls. IDEA total score mediated the relationship between avoidant attachment and EDI-2 interoceptive awareness.

These findings demonstrate that in ED patients insecure attachment is correlated to disorder of identity and lived corporeality that, in turn, mediates the association between attachment and a specific ED psychopathological trait. Therefore, we suppose that early relationships, through the development of disturbances in identity and embodiment, lead to altered perception of bodily signals and deranged discrimination of one's emotions, which could contribute to EDs.
