In study 2, a community sample completed the MBEQ and measures assessing severity of binge eating, irrational food beliefs, anxiety, depression, impulsiveness. A Confirmatory Factor Analysis (CFA) was performed. Concurrent and incremental validity were assessed. In study 3, a clinical sample of participants with a diagnosis of BED completed the MBEQ and other measures. Bivariate correlational analysis and hierarchical linear regression were performed. Participants from the general population and participants with a diagnosis of BED were compared. EFA and CFA supported a two-factor solution consisting of positive and negative metacognitions about binge eating. Concurrent and incremental validity were acceptable. The metacognitions factors correlated positively with anxiety, depression, irrational food beliefs, impulsiveness in the community sample, and anxiety, irrational food beliefs, impulsiveness in clinical sample. The metacognitions factors contributed to the prediction of b...
