OBJECTIVE This study examined group differences in ratings of amounts of food at the threshold of what is considered "unusually large" to develop empirically derived definitions of binge eating criteria for bulimia nervosa and binge eating disorder. METHOD Groups included undergraduate students, community members, and participants from an eating disorder (ED) longitudinal study. Data were col...

This study examined the relations between weekly reports of anxiety, dimensions of trait perfectionism, and dieting and binge eating over the course of 11 weeks. Participants were 406 college women who completed a battery of questionnaires at Time 1 that assessed trait-like characteristics (e.g., self-oriented and socially prescribed perfectionism). For 11 weeks following that, participants fil...

OBJECTIVE Food concocting, or making strange food mixtures, is well documented in the famine and experimental semistarvation literature and appears anecdotally in rare descriptions of eating disorder (ED) patients but has never been scientifically investigated. Here we do so in the context of binge-eating using a "famine hypothesis of concocting." METHOD A sample of 552 adults varying in bing...

OBJECTIVE To examine temporal trends in the burden of eating disorder (ED) features, as estimated by the composite of their prevalence and impact upon quality of life (QoL) over a period of 10 years. METHODOLOGY Representative samples of 3010 participants in 1998 and 3034 participants in 2008 from the South Australian adult population were assessed for endorsement of ED features (objective bi...

Binge eating occurs across the entire range of eating disorders. It is required for a diagnosis of bulimia nervosa but it is also seen in some cases of anorexia nervosa and in many cases of eating disorder not otherwise specified (usually referred to as eating disorder NOS or atypical eating disorder). This article focuses on the management of those eating disorders in which binge eating is a p...

Objective. This study aimed to investigate potential differences in appetite sensations, ghrelin, peptide YY, and glucose and their relationship with energy and macronutrient intake in obese adolescents with subclinical binge eating disorder. Methods. Fifteen obese adolescents (six and nine individuals with and without subclinical binge eating disorder, resp.) qualified for this study. Visual a...

OBJECTIVE The dopaminergic system is associated with feelings of pleasure and reward and with positive hedonic processes related to food, sexual activity and certain substances. Because it is recognized that patients who have eating disorders with binge-eating behaviour have a high comorbidity of substance dependence, we examined the association between the variable number of tandem repeats (VN...

OBJECTIVE Eating disorders develop through a combination of genetic vulnerability and environmental stress, however the genetic basis of this risk is unknown. METHODS To understand the genetic basis of this risk, we performed whole exome sequencing on 93 unrelated individuals with eating disorders (38 restricted-eating and 55 binge-eating) to identify novel damaging variants. Candidate genes ...

It has been hypothesized that restrictive eating allows individuals with anorexia nervosa (AN) to avoid contact with negative emotions; however, this presumption has not been directly tested. In this study, we conducted an initial investigation examining whether restrictive eating serves an emotional avoidance function among individuals with AN. Females with AN (n = 118) reported on negative an...

OBJECTIVE Adoption of effective treatments for recurrent binge-eating disorders depends on the balance of costs and benefits. Using data from a recent randomized controlled trial, we conducted an incremental cost-effectiveness analysis (CEA) of a cognitive-behavioral therapy guided self-help intervention (CBT-GSH) to treat recurrent binge eating compared to treatment as usual (TAU). METHOD Pa...
