“…About one third of sub-population at risk to eating disorders stated that they heard negative comments about their weight from peers and family members, indicating social pressure; surprisingly, some 70% of them were convinced about the need to be thin on their wedding night. eating disorders [13,20]. The prevalence of eating disorders risk found in this study (31.4%) is higher than what was reported by number of earlier studies targeting the UAE population; there, scores above the EAT-26 cutoff did not exceed a quarter of the surveyed population [7,25,26].…”

Background: Growing evidence is showing high levels of physical inactivity and disordered eating attitudes among young females in the United Arab Emirates. This is clearly concerning, but little is known about the activity level of those with disordered eating attitudes and their dieting behavior. This study examines the female Emirati college students’ disordered eating attitudes and its relation to exercise behavior.Method: A cross- sectional study using a validated and reliable questionnaire was conducted on 242 Emirati female students attending a public university in Dubai. Eating Attitudes Test- 26 (EAT26) was used to measure eating attitudes and the short International Physical Activity Questionnaire (IPAQ) was included to measure physical activity level. A systematic random sampling from a list of classes in the fall 2014 semester was used for recruitment. The university’s Research Ethics Committee approved the study and consents were obtained from participants. SPSS v.21 was used for data analysis. Chi-square test was used to compare frequencies. Significance level was set at 0.05.Results: The participants’ mean age and standard deviation (Mean± SD) was 19 ±1.3 years. 31.4% of the participants showed disordered eating attitudes. The percentage of participants engaged in at least one concerning behavior in the past six months was 43.8%. A membership in a health club was significantly related to disordered eating attitudes (p <0.01). A high level of physical activity was correlated with laxative use, over the counter supplements, and exercising for more than 60 minutes to control weight (p<0.05). Conclusion: There is a great need for intervention programs and policies to contain the level of abnormal eating attitudes and promote healthy level of physical activity among college students.

On the basis of the restraint theory and the continuum hypothesis of eating disorders, the objective of this paper was twofold. First, subjects who, on the basis of items from the Eating Disorder Examination Questionnaire (EDE-Q) which are generated from DSM-III-R diagnostic criteria, fulfilled the diagnostic criteria for anorexia nervosa (AN) and bulimia nervosa (BN) were identified. Second, differences in scale scores between a case group and a non-case group were tested, and case group distribution of the two self-report questionnaires Eating Attitudes Test (EAT-12) and Eating Disorder Inventory (EDI) was compared as a means for investigating the sensitivity of the instruments in detecting eating disorder cases. In a classroom setting 224 8th-grade female students from 5 schools in western Norway completed the questionnaires. The responses to the questionnaires were analysed by case group and instrument/subscales by using the t test, Cohen's d-values, eta squared statistic, point biserial correlation, and two-way ANOVA. No BN cases and 10 AN cases were identified. AN cases scored significantly higher on all measures of eating problems than normal subjects and differed most from non-cases on the "dieting" dimension. Clinical implications are discussed in the light of screening.

“…Reliability information for either the total EAT score or one or more factor scores for their sample was reported in 78 (36.28%) studies. Seven of these studies were excluded from further analysis because the authors modified the measure or used different factors based on their own factor analysis of the EAT (see [ 26 , 28 - 30 , 69 - 135 ] for included studies). Results indicate that the sample-weighted mean estimates of internal consistency were .81 for the EAT-40 and .86 for the EAT-26.…”

“…Research suggests that the EDI can distinguish individuals with AN [ 25 ] and BN [ 29 ] from nonclinical respondents. Conversely, the Eating Attitudes Test (EAT; [ 26 ]) assesses thoughts and behaviors related to anorexia nervosa and may be administered in the original 40-item version or a 26-item short form (EAT-26; [ 28 ]), both of which are typically highly correlated ( r = .98; [ 30 ]). The EAT has also been shown to discriminate individuals with bulimia nervosa from control participants [ 29 ], eating disordered patients and controls, and binge eating patients from those with anorexia nervosa and bulimia nervosa [ 31 ].…”

Measuring eating disorder attitudes and behaviors: a reliability generalization study

BackgroundAlthough score reliability is a sample-dependent characteristic, researchers often only report reliability estimates from previous studies as justification for employing particular questionnaires in their research. The present study followed reliability generalization procedures to determine the mean score reliability of the Eating Disorder Inventory and its most commonly employed subscales (Drive for Thinness, Bulimia, and Body Dissatisfaction) and the Eating Attitudes Test as a way to better identify those characteristics that might impact score reliability.MethodsPublished studies that used these measures were coded based on their reporting of reliability information and additional study characteristics that might influence score reliability.ResultsScore reliability estimates were included in 26.15% of studies using the EDI and 36.28% of studies using the EAT. Mean Cronbach’s alphas for the EDI (total score = .91; subscales = .75 to .89), EAT-40 (total score = .81) and EAT-26 (total score = .86; subscales = .56 to .80) suggested variability in estimated internal consistency. Whereas some EDI subscales exhibited higher score reliability in clinical eating disorder samples than in nonclinical samples, other subscales did not exhibit these differences. Score reliability information for the EAT was primarily reported for nonclinical samples, making it difficult to characterize the effect of type of sample on these measures. However, there was a tendency for mean score reliability to be higher in the adult (vs. adolescent) samples and in female (vs. male) samples.ConclusionsOverall, this study highlights the importance of assessing and reporting internal consistency during every test administration because reliability is affected by characteristics of the participants being examined.
