Objective: To explore the psychometric properties of the Italian version of the Bulimic Investigatory Test, Edinburgh (BITE). Subjects: A general population sample of 995 subjects (621 females), a clinical sample of 388 eating disordered females and a clinical sample of 710 patients with obesity (575 females). Results: Internal consistency was satisfactory. The factor analysis confirmed that the Symptom Scale is mono-factorial. Patients with bulimia nervosa (BN) purging showed the highest scores and those with anorexia nervosa (AN) restricting type the lowest. Obese patients showed higher BITE scores than controls in both sexes (p<0.01) and those with binge eating disorder (BED) showed higher scores than the rest of the sample (p<0.05). In patients with obesity with the threshold of 10 the Symptom Scale had a sensitivity for BED of 93% and a specificity of 55%; with the threshold of 20, sensitivity and specificity were, respectively, 44% and 92%. Normative values for BITE total and sub-scale scores in clinical and non-clinical samples are reported. Conclusion: The Italian version of BITE is psychometrically sound and it can be a useful screening tool. Our data suggest that Symptom Scale, with a threshold of 20, has a good sensitivity for BN, although it does not effectively discriminate patients with BN from those affected by other eating disorders with binge-eating (BED, AN bingeing-purging type) .

The Eating Disorder Inventory in the screening for DSM-5 binge eating disorder
Eating behaviors, 2016
We assessed whether the Eating Disorder Inventory (EDI) is suitable for screening binge eating disorder (BED) in young women. Young women (N=2825) from the 1975-79 birth cohorts of Finnish twins were assessed by questionnaires, including subscales of the EDI. For a subset of women (N=548), we established DSM-5 diagnoses of BED; 16 women had lifetime BED. We compared screening properties of the EDI scales using receiver operating characteristic (ROC) analysis, determined optimal cutoff points, and calculated sensitivities and specificities. The best screen for DSM-5 BED was the global score of three subscales (Bulimia, Drive for Thinness, Body Dissatisfaction) with an area under the curve (AUC) of 0.86. Its sensitivity was 87% and specificity 76% at cutoff ≥21. Three individual subscales had acceptable screening properties: Bulimia (AUC 0.83; sensitivity 80%, specificity 78% at cutoff ≥2), Drive For Thinness (AUC 0.82; sensitivity 87%, specificity 72% at cutoff ≥7), and Body Dissatis...
Eating and Weight Disorders - Studies on Anorexia, Bulimia and Obesity, 2020
Purpose Obese, behavioral weight-loss (BWL) seeking individuals may be prone to over-reporting binge-eating (BE). However, many studies rely on self-reported measures of BE in this population, which may be inaccurate. As such, this is the first-ever study to examine the concordance rates among one self-reported and one clinician-administered measure of BE in a BWL-seeking sample with overweight/obesity. Methods At baseline of a BWL trial, participants (N = 94) completed two measures of BE: The Eating Disorders Examination Questionnaire (EDE-Q) and the interview-based Eating Disorder Examination (EDE, Overeating section). Results Cohen's kappa detected poor agreement between measures (κ < 0). A paired samples t-test detected large, significant differences in OBE frequency across the EDE-Q and EDE, p < 0.001. The self-reported EDE-Q detected a significantly greater frequency of OBEs compared to the EDE (M EDE-Q = 0.73, SD = 1.29 vs. M EDE = 0.06, SD = 0.34). The EDE-Q detected that approximately 50% of participants have experienced OBEs, while the EDE detected that only 5% of participants have experienced OBEs. The frequency of OBEs detected by the EDE-Q was statistically greater than the frequency of OBEs detected by the EDE, p < 0.001. Discussion Results suggest poor agreement between one self-reported measure and the "gold-standard," clinician-administered measure of BE in a BWL-seeking sample with overweight/obesity. The EDE-Q exhibited high sensitivity but lowto-moderate specificity of OBEs, with the number of false positives (41) outweighing that of true positives (4). Studies measuring BE in this population should consider relying solely on assessor-administered measures, as this sample may require clinical guidance or clarification on the definition and features of BE.

Eating Disorder Examination Questionnaire (EDE-Q-13): Expanding on The Short Form
2020
Objective: The Eating Disorders Examination–Questionnaire (EDE-Q) is widely used but is time-consuming to complete. In recent years, the advantages and disadvantages of several brief versions have therefore been investigated. A seven-item scale (EDE-Q-7) has excellent psychometric properties but excludes items on bingeing and purging. This study aimed to evaluate a thirteen-item scale (EDE-Q-13) including items on bingeing and purging. Method: Participants were 1,160 (188; 11.4% males) community volunteers aged 28.79±9.92. They completed the full EDE-Q and measures of positive body experience, social and emotional connection, life satisfaction, positive and negative affect and positive eating. The six EDE-Q items about bingeing and purging, recoded to correspond to the response categories of the other EDE-Q questions, were added to the EDE-Q-7, resulting in the EDE-Q-13. Results: Confirmatory factor analysis confirmed the hypothesized EDE-Q-13 structure, including the bingeing and p...

Objective—This study assessed the utility of the Binge Eating Scale (BES) as a measure of binge eating disorder (BED) in patients seeking bariatric surgery by a) determining the optimal BES cutscore for predicting BED, b) calculating concordance statistics, and c) determining the predictive value of each BES item. Method—480 patients presented for a psychological evaluation prior to Roux-en-Y gastric bypass surgery. The BES and the SCID semi-structured interview for BED were administered. Results—ROC curve analyses identified an optimal BES cut-score of 17, which correctly classified 78% of patients with BED. A cut-score of 27 improved this statistic, but increased the number of false negatives. Discriminant function analyses revealed that nearly all BES items significantly predicted BED. Discussion—The BES is a valid screener of BED in a bariatric surgery seeking population. Clarifying the screening process for binge eating can help improve the assessment and treatment of patients ...
Development and construct validation of a self-report measure of Binge eating tendencies
Addictive Behaviors, 1980
Bulimia is an eating disorder purported to comprise binge eating episodes with subsequent depressive moods and self-deprecating thoughts. This study reports the development and preliminary construct validation of a Binge Scale intended to provide more descriptive, quantifiable information about the behavioral and attitudinal parameters of bulimia. Over two-thirds of the females and nearly one-half of the males in the samples reported binge eating occurrences. The severity of binge eating was associated with degree of dieting concern ("restraint") and inversely related to self-image acceptance, particularly among females. Maintaining body weight below "set point" through restrained eating efforts may increase the susceptibility to periodic binge episodes.
Refining the definition of binge eating disorder and nonpurging bulimia nervosa
The International journal of eating disorders, 2003
The diagnostic concept of binge eating disorder (BED) was introduced in response to the clinical observation of Stunkard (1959) that some people with obesity have recurrent episodes of binge eating. We suggest that the DSM-IV concept of BED has resulted in the recruitment of heterogeneous research samples, amongst which are some people with BED, as described by Stunkard, some with bulimia nervosa, some with other types of eating disorder, and some with no eating disorder. We consider the difficulties distinguishing BED from other forms of overeating, especially in patients with obesity, and from nonpurging bulimia nervosa. We propose revised diagnostic criteria for BED and bulimia nervosa that are designed to minimize these problems.
Eating Disorder Examination Questionnaire (EDE-Q)
European Journal of Psychological Assessment, 2012
Objective: To determine the optimal Eating Disorder Examination-Questionnaire (EDE-Q) global score to discriminate between female controls and patients by eating disorder (ED) diagnosis, body mass index (BMI) and age. Method: A sample of 1845 control participants and 620 patients from specialty ED treatment centres. Results: Mean global EDE-Q was 4.00 [standard deviation (SD) = 1.32] for patients and 1.25 (SD = 1.10) for controls. Receiver operating characteristic analyses demonstrated an area under the curve of 0.93 (95% CI: 0.91-0.94), with an optimal cutoff score of 2.50 (sensitivity = 0.86; specificity = 0.86), ranging from 2.09 for anorexia nervosa, 2.62 for bulimia nervosa and 2.63 for ED otherwise not specified. Optimal cutoff scores also varied according to BMI, ranging from 1.62 (BMI ≤ 18.0 kg/m 2) to 3.26 (BMI ≥ 30 kg/m 2), with less variability for age, ranging inversely from 2.16 (>40 years) to 2.70 (<20 years). Discussion: The global EDE-Q score showed high discriminant validity, and findings illustrate the particular importance of considering BMI and diagnosis when applying cutoffs based upon the EDE-Q.
