Psychometric properties of shortened versions of the Eating Disorder Examination-Questionnaire in Brazilian women.
Article in Eating and weight disorders : EWD, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe Eating Disorder Examination-Questionnaire (EDE-Q) is a widely used 28-item instrument for screening eating disorders, of which 22 are attitudinal items used to compute subscale scores and to assess factorial structure, while six open-ended items assess behavioral frequency and are excluded from dimensional analyses. Shorter versions, such as the EDE-Q7, EDE-Q8, and EDE-Q18, have been proposed to enhance accessibility and psychometric properties. This study aimed to evaluate different factorial structures of the EDE-Q and identify the model that best fits a sample of Brazilian adult women.
methodsA total of 712 women completed the EDE-Q and measures of body satisfaction and sociocultural pressures. The factorial structure was analyzed through confirmatory factor analysis (CFA), and convergent validity and internal consistency were also assessed.
resultsThe multifactorial structure of the original EDE-Q and the 18-item model did not fit the sample well. Although the 7-item model showed acceptable fit, the 8-item version demonstrated the best fit. The EDE-Q8 factors showed a negative association with appearance evaluation and body area satisfaction, and a positive association with internalization of the thin and muscular body ideal and body mass index. Internal consistency was adequate.
conclusionThe 8-item short version of the EDE-Q is a reliable and practical psychometric tool for assessing disordered eating behaviors in Brazilian adult women. Future studies should explore the psychometric performance of the EDE-Q8 across different age ranges, gender groups, and clinical populations to strengthen evidence for its cross-cultural validity and generalizability. LEVEL OF EVIDENCE: Level III, well-designed cohort or case-control analytic studies.
