| Objective We examined the association between lifetime nonsuicidal self-injury (NSSI), emotion regulation, and food addiction (FA) in women (n = 220) with eating disorders (ED) compared with (n = 121) healthy controls (HC). Method Results Participants were assessed via face-to-face interviews for ED diagnosis and lifetime NSSI. FA was assessed with Yale Food Addiction Scale 2.0 and emotion regulation using the Difficulty in Emotion Regulation Scale (DERS). The prevalence of FA was significantly higher among women with an ED when compared with HC (75.9% vs. 4.1%, p < 0.001). Similarly, subjects presenting FA showed a high prevalence of lifetime NSSI, in both ED and HC (40.7% and 60.0%, respectively). Our predictive model revealed FA and DERS total scores as indicators of the presence of lifetime NSSI independent of group assignment, ED diagnosis, and age. Conclusions These findings suggest a shared aetiology between ED, NSSI, and FA, explained possibly in part by emotion-regulation deficits. |
