From the research article’s abstract: “The Yale Food Addiction Scale 2.0 (YFAS) assesses addiction-like eating of palatable foods based on the 11 diagnostic criteria for substance use disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study was the first to investigate the factor structure, psychometric properties, and clinical significance of the YFAS 2.0 in individuals with binge-eating disorder (BED) symptomatology. Data were analysed from 220 community-based participants who met criteria for “probable BED” based on self-report symptom frequency. Classification of food addiction (FA) was met by 42.3% of the sample. The YFAS 2.0 exhibited a unidimensional structure, adequate internal consistency, and convergent and incremental validity.
