'Food addiction' refers to the idea that certain highly palatable foods can trigger an addictive-like process in susceptible individuals. The aim of this study was to assess the prevalence and clinical significance of 'food addiction' symptoms in binge eating disorder (BED) using the second version of the Yale Food Addiction Scale (YFAS 2.0). Participants were 71 individuals with BED and 79 individuals with no history of an eating disorder (NED). The Eating Disorder Examination 17.0 (EDE) was used to diagnose BED and to measure binge eating. Participants completed self-report measures of eating disorder psychopathology, psychological distress, and the YFAS 2.0. Results indicated that the BED group reported significantly higher 'food addiction' scores compared to the NED group after controlling for relevant covariates. In fact, 92% of the BED group met YFAS 2.0 criteria for at least mild 'food addiction' compared to only 6% of the NED group. BED participants who met criteria for Moderate/Severe 'food addiction' reported significantly higher eating disorder psychopathology (except dietary restraint) as well as higher levels of anxiety and depression than BED participants with No/Mild 'food addiction'. Scores on the YFAS 2.0 positively predicted binge frequency, but not global eating disorder psychopathology, in the BED group after controlling for body mass index (BMI), depression and anxiety. The high rate of 'food addiction' symptoms in the BED group may reflect overlap between the symptoms assessed by the YFAS 2.0 and the clinical features of BED. A focus on identifying overlapping and distinctive underlying mechanisms rather than similarities and differences in clinical features might be a more fruitful avenue for future research on BED and 'food addiction'.
