Food Addiction (FA) consists of recurrent and maladaptive consumption of hyper-palatable foods (rich in carbohydrates, fats and/or salt), leading to clinical suffering and/or psychosocial impairment. The development of the Yale Food Addiction Scale (YFAS) represented a framework for the evaluation of FA. The vast majority of studies with humans occurred in developed countries and there was no validation of the brazilian version of YFAS. The present study aimed to validate the modified Yale Food Addiction Scale (mYFAS 2.0), estimate the prevalence of FA and determine the association of correlates of mental health and quality of life among internet users positively tracked for food addiction (FA+). A total of 7,639 anonymous respondents (71.3% women, age: 27.2 ± 7.9 years) were consecutively included through an electronic research site, which provided data capture and database registration. The participants provided sociodemographic information and answered scales to assess symptoms of food addiction (YFAS 2.0m), impulsivity (BIS 11), depression (PHQ-9), bipolar spectrum disorder (HCL-32), suicidal ideation, skin peaking (SPSQ), trichotillomania (MIDI), psychopathological dimensions (SCL-90R), early traumas (ETISR-SF) and quality of life (WHOQOL-BREF). The YFAS 2.0m showed adequate internal consistency (Cronbach's alpha=0.89). A single factor solution produced the best quality adjustment parameters of the scale. In addition, YFAS 2.0m correlated with BIS 11 total and subscale scores (ρ=0.26, P <0.001). The prevalence of FA was 4.32% (95% CI: 3.89- 4.80%). FA was associated with a positive screening for major depressive episode (OR = 4.41, 95% CI: 3.46-5.62), bipolar spectrum disorder (OR=1.98, 95% CI: 1.43-2.75), skin peaking (OR=2.02, 95% CI: 1.31- 3.09), psychological and sexual abuse (P=0.008), as well as poorer quality of life (P <0.001). It is concluded that the brazilian version of YFAS 2.0m showed good internal consistency, factor structure and validity convergent with BIS 11. The estimated prevalence is lower than that found in previous studies, but also suggests that AdA is a common phenotype. The results suggest significant comorbid psychopathology and poorer quality of life. Prospective studies
