Abstract
This study aims to test a model where low self-monitoring (a sub-function of first-person domain of metacognition) and high negative urgency lead to a worsening of binge severity through the mediation of emotional dysregulation in patients with binge eating disorder (BED). Forty non-BED-obese and 46 BED-obese patients completed a battery of tests assessing metacognition and psychopathology. To test our hypothesized model, a structural equation model (SEM) using maximum likelihood estimation was conducted. BED-obese patients had significantly higher scores in BES, UPPS-P Negative urgency, and DERS total score, and lower MSAS self-monitoring than non-BED-obese, while no differences emerged in the MSAS others-monitoring subscale. The structural model demonstrated very good fit indexes (χ2 = 1.377, df = 2; p = .502, CMIN/DF = 0.688, CFI = 1.000, RMSEA = 0.000, TLI = 1.047) and all paths were significant in the predicted directions. These preliminary findings show that, low self-monitoring and high negative urgency lead BED-obese patients to express the worsening of binge severity through the mediation of emotional dysregulation. This knowledge may be helpful in the clinical practice to develop a tailor-made treatment. Accordingly, an approach through Metacognitive Interpersonal Therapy could be attempted in BED-obese patients with these characteristics. Highlights Patients with BED exhibited low self-monitoring and high negative urgency. Binge severity was mediated by high level of emotional dysregulation. Metacognitive Interpersonal Therapy may be useful for BED patients.
