In a cross-sectional study conducted four years ago to assess the validity of the Brazilian version of the Eating Attitudes Test-26 (EAT-26) for the identification of abnormal eating behaviors in a population of young females in Southern Brazil, 56 women presented abnormal eating behavior as indicated by the EAT-26 and the Edinburgh Bulimic Investigation Test. They were each matched for age and neighborhood to two normal controls (N = 112) and were re-assessed four years later with the two screening questionnaires plus the Composite International Diagnostic Interview (CIDI). The EAT results were then compared to diagnoses originating from the CIDI. To evaluate the temporal stability of the two screening questionnaires, a test-retest design was applied to estimate kappa coefficients for individual items. Given the prevalence of eating disorders of 6.2%, the CIDI psychiatry interview was applied to 161 women. Of these, 0.6% exhibited anorexia nervosa and 5.6%, bulimia nervosa (10 positive cases). The validity coefficients of the EAT were: 40% sensitivity, 84% specificity, and 14% positive predictive value. Cronbach's coefficient was 0.75. For each EAT item, the kappa index was not higher than 0.344 and the correlation coefficient was lower than 0.488. We conclude that the EAT-26 exhibited low validity coefficients for sensitivity and positive predictive value, and showed a poor temporal stability. It is reasonable to assume that these results were not influenced by the low prevalence of eating disorders in the community. Thus, the results cast doubts on the ability of the EAT-26 test to identify cases of abnormal eating behaviors in this population.

European eating disorders review : the journal of the Eating Disorders Association, 2014
Objective: The first aim of the current study was to establish general population norms for the Portuguese version of the Eating Disorder Examination Questionnaire (EDE-Q) in a large community sample of female adolescents and young women, as well, for a diverse Eating Disorder (ED) clinical sample, and for women with obesity without an ED. A second aim of the study was to assess the discriminant validity of the EDE-Q and providing cut-off scores for the total scale and subscales. Method: A sample of female adolescents and young women (N = 4091) from the general population, 416 women who met diagnostic criteria for an ED and 138 women seeking obesity treatment completed the EDE-Q. Results: Norms for the EDE-Q global subscale were provided. Within the community sample, norms were provided for both high school and college samples. Receiver operating characteristic analysis showed that the EDE-Q total score accurately discriminate between participants with and without an ED. Current norm contributes to the clinical utility of the EDE-Q, providing both a cut-off score and reliable change index. Results showed that the EDE-Q is a reliable instrument, but the theorized four subscales structure was not supported by an explorative factor analysis. Conclusion: Results will help both researchers and clinicians interpreting the EDE-Q scores and to establish comparison with data produced in different countries.
Development and validation of the Portuguese version of the Eating Disorder Diagnostic Scale
Ansiedad y Estrés, 2018
This article presents the psychometric properties for the Portuguese population of a brief self-report scale for diagnosing anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED): the Eating Disorder Diagnostic Scale . Method: To study the psychometric properties of EDDS, an exploratory factor analysis was done first, followed by a confirmatory factor analysis. Results: The results of the exploratory factor analysis revealed the existence of three components and the confirmatory factor analysis showed a structure with three latent variables (Body and Weight Concerns, Binge Eating Behaviour and Compensatory Behaviours), with a second order variable (Eating Disorder Symptoms) with a good adjustment fit. The internal consistency and the test-retest correlations revealed an adequate reliability and the inter-correlations of the EDDS subscales with other measures of the same and different constructs, supported the convergent and discriminant validity of this measure. Conclusions: Summing up, the EDDS seems to be a useful measure to assess eating disorders symptomatology in the Portuguese population.
Psychometric evaluation of the Disordered Eating Attitude Scale (DEAS). English version
Appetite, 2010
Eating attitudes are defined as beliefs, thoughts, feelings, behaviors and relationship with food. They could influence people's food choices and their health status. Objective: This study aimed to adapt from Portuguese to English the Disordered Eating Attitude Scale (DEAS) and evaluate its validity and reliability. The original scale in Portuguese was translated and adapted into English and was applied to female university students of University of Minnesota—USA (n = 224). Internal consistency was determined (Cronbach's Alpha). Convergent validity was assessed by correlations between Eating Attitude Test-26 (EAT-26) and Restrain Scale (RS). Reliability was evaluated applying twice the scale to a sub-sample (n = 30). The scale was back translated into Portuguese and compared with the original version and discrepancies were not found. The internal consistency was .76. The DEAS total score was significantly associated with EAT-26 (r = 0.65) and RS (r = 0.69) scores. The correlation between test–retest was r = 0.9. The English version of DEAS showed appropriate internal consistency, convergent validity and test–retest reliability and will be useful to assess eating attitudes in different population groups in English spoken countries.
The Eating Attitudes Test (EAT-26): Reliability and Validity in Spanish Female Samples
The Spanish journal of psychology, 2010
This paper focuses on the validation of the Spanish form of the Eating Attitudes Test (EAT-26; Garner, Olmsted, Bohr & Garfinkel, 1982) across two studies. Participants in Study 1 were 778 females recruited from community settings (aged 12-21). Study 2 included 86 females recruited from clinical and 86 females from community settings (aged 12-35). Results from Principal and Simultaneous Component Analyses showed a unidimensional structure of the EAT-26 item scores. Reliability analyses supported the internal consistency of the scale. Study 1 also explores the ability of the EAT-26 to discriminate between subjects with Eating Disorder (ED), Symptomatic or Asymptomatic by means of ROC analyses and using results from the Questionnaire for Eating Disorder Diagnoses (Q-EDD; Mintz, O'Halloran, Mulholland, & Schneider, 1997) as criterion. The EAT-26 demonstrated good specificity but insufficient sensitivity to detect a full or partial ED. Study 2 explores the ability of the questionnai...
Psychometric properties of the Eating Attitudes Test
Measurement in Physical …, 2007
The study was designed to examine the construct validity and internal consistency reliability of the Eating Attitudes Test (EAT) using a confirmatory factor analysis (CFA). Two widely adopted EAT models were tested: three-factor (Dieting, Bulimia and Food Preoccupation, and Oral Control) with 26 items , and four-factor (Dieting, Oral Control, Awareness of Food Contents, and Food Preoccupation) with 20 items . Research participants included two samples of female college students (calibration N = 785, cross-validation N = 298). Maximum Likelihood estimation method was adopted. The fit indexes from the three-factor EAT-26 represented unacceptable model fit (RMSEA = .11, SRMR = .11, CFI = .73, AGFI = .74). Similarly, the fit indexes from the four-factor EAT-20 model provided a poor fit (RMSEA = .09, SRMR = .07, CFI = .85, AGFI = .83); however, after eliminating four items with low factor loadings, the four-factor EAT model with 16 items was found to have an acceptable fit (RMSEA = .08, SRMR = .05, CFI = .91, AGFI = .88). The EAT-16 model was then crossvalidated on an independent sample and was found to have acceptable configural and metric invariance as well as internal consistency reliability.
The Portuguese Version of the Eating Disorders Inventory: Evaluation of Its Psychometric Properties
European Eating …, 2001
The objective of the present study was to examine the psychometric properties of the Portuguese version of the Eating Disorders Inventory (EDI; . Three groups participated in the current study: 274 female and 67 male non-patients, and 83 females with a diagnosis of eating disorder. Results clearly support the reliability and the factor structure of the EDI in a Portuguese sample. In addition non-patient and eating disordered participants' score signi®cantly differently in all EDI scales, emphasizing the clinical usefulness of the measure.
The psychometric properties of the Eating Attitude Test in a non-Western population
Social psychiatry and psychiatric epidemiology, 1994
The psychometric features of the Eating Attitude Test Questionnaire (EAT) are described in an Egyptian population of secondary school girls (n = 351). Confirmatory factor analysis, modelled on studies by Garner et al. (1982) and Eisler and Szmukler (1985), was conducted and pointed to the overall coherence of the EAT in this population. The assessment of the internal validity of each factor, however, showed a high level of consistency amongst the items representing the dieting factor, and a much lower level for those representing the bulimia factor. The results could justify the continued use of the EAT as a valid screening instrument for some aspects of eating morbidity, i.e. dieting and concern about weight and shape in non-Western populations. The analysis clearly suggested that another scale is required for bulimic behaviours.
Factor Analysis of the Eating Attitude Test (EAT-40) among a group of Malaysian University Students
Eating disorders are a group of mental health concerns characterized by disturbance in eating behaviour that include, anorexia, bulimia, binge eating disorder, and other types of disordered eating. Adolescents are becoming increasingly vulnerable to eating disorders. The Eating Disorder Attitude Test (EAT-40) is a widely used screening instrument for detecting eating disorders. Several authors have translated the EAT-40 in various languages and validated the scale. The objective of the study included determining the factor structure of EAT-40 and to find the reliability. Method: 217 undergraduate university students in Malaysia were administered the EAT-40. In addition, they were also administered the Rosenberg’s Self Esteem scale to study the correlates of EAT-40. Results: The mean age of students was 22 years. The factor analysis of EAT-40 revealed a 34 item EAT model, with four subscales, ‘Dieting Behaviour’, ‘Oral Control’, ‘Food Preoccupation’ and ‘Body Image’. The short form i...
