Ten Years of the Yale Food Addiction Scale: a Review of Version 2.0

AbstractPurpose of ReviewThe Yale Food Addiction Scale (YFAS) is a self-report questionnaire for the assessment of addiction-like consumption of high-calorie, processed foods. The original scale was developed in 2009 and —for its tenth anniversary—we now review studies using its revised version—the YFAS 2.0.Recent FindingsThe 11 symptoms of food addiction as measured with the YFAS 2.0 demonstrated high internal reliability and a unidimensional structure in several studies, supporting construct validity. Similar to the original YFAS, highest prevalence rates of YFAS 2.0 diagnoses were found in individuals with bulimia nervosa, followed by binge eating disorder, anorexia nervosa, subthreshold eating disorders, obesity, and unselected samples. Scores on the YFAS 2.0 were associated with other disordered eating behaviors and several co-morbid mental disorders.SummaryThe YFAS 2.0 is an internal reliable measure that shows factorial validity, yet more studies are needed that demonstrate retest-reliability and predictive validity. Prevalence rates and correlates of YFAS 2.0 diagnoses are largely similar to those observed with the original YFAS.

In the wave of laws passed prior to the end of the recent legislative session in New York, one in particular will go a long way toward helping medical patients in need. The bill amended New York’s Mental Health Parity Law to expand what insurance providers must cover when it comes to eating disorders. Previously, providers were only mandated to cover anorexia and bulimia. “What people don’t understand is human beings don’t fit neatly into boxes. Just be cause you don’t fit into a box…

Conclusion: Phentermine–topiramate could be helpful for weight loss and reduction of binge-eating symptoms in patients with obesity or overweight in addition to BED. Controlled studies are warranted. Binge-eating disorder (BED), an eating disorder recognized in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5), is characterized by recurrent and distressing episodes of binge eating (eating an unusually large amount of food with a sense of loss of control over eating) without inappropriate compensatory weight-loss behaviors.1 Known as the most common eating disorder, BED is strongly assoc...

Here’s how to take that first small step. Food addiction is real. And if you’re struggling with food addiction, know that you’re not alone — I’ve been there, too. In fact, the younger you are, the more likely it’s your struggle. From my past experience as a compulsive overeater, I suspect that many food addictions act as pacifiers for pain, fears, and anxieties, and even as ways to celebrate emotional spikes that are positive. Food seems to act as a life enhancer, while offering the illusion of short-term emotional balance. As a food addict, you’ve established neural pathways and a...

CONCLUSIONS: Food addiction (FA) may be used as a proxy for (1) bulimic eating disorder severity, (2) complex trauma histories, (3) severity of PTSD and PTSD symptoms, (4) intensity of psychiatric comorbidity, (5) severity of obesity, as well as (6) their combination. Implications for developing treatment strategies are discussed. The case for a comprehensive management that requires careful attention to medical and psychiatric assessment and integrated care that incorporates trauma-focused treatment is made.

Think about your favorite holiday food. Maybe pecan pie, maybe roast beef, maybe stuffing, maybe sugar cookies. Let’s say you are hungry. Think about eating that food right now. Do you feel excitement? Pleasure? Anxiety? Internal conflict? Guilt? Are you thinking about the calories? The grams of fat? Carbs? Whether you exercised enough today and are allowed to eat it? If you ate this food, how long would your feelings about it last? Would you feel guilt all day? Would the anxiety about eating it linger and affect your mood? Would you feel fat or uncomfortable in your own skin? Think about your friends or family memb...

Authors: Meule A Abstract In recent years, the concept of food addiction has gained more and more popularity. This approach acknowledges the apparent parallels between substance use disorders and overeating of highly palatable, high-caloric foods. Part of this discussion includes that "hyperpalatable" foods may have an addictive potential because of increased potency due to certain nutrients or additives. Although this idea seems to be relatively new, research on food addiction actually encompasses several decades, a fact that often remains unrecognized. Scientific use of the term addiction in reference t...
