Validation for Brazilian Portuguese of the Eating Behavior Phenotypes Scale (EFCA): confirmatory factor analysis and psychometric properties.
Article in Archives of endocrinology and metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo validate the psychometric properties of the Eating Behavior Phenotypes Scale (EFCA) and to analyze the stability of the construct and its external validity in Brazilian Portuguese. SUBJECTS AND
methodsA total of 206 adult participants completed a self-administered survey designed to identify eating behavior phenotypes. Confirmatory factor analysis was performed, and internal consistency was assessed using Cronbach's alpha coefficient. Concurrent validity was evaluated through Pearson's correlation between EFCA scores and body mass index. Translation involved independent forward translation from Argentinian Spanish to Brazilian Portuguese, followed by back-translation from Brazilian Portuguese to Spanish. The Brazilian Portuguese version was administered following 100% agreement between the versions.
resultsThe EFCA and its subscales in Brazilian Portuguese showed acceptable internal consistency (α = 0.83).
conclusionConfirmatory factor analysis indicated a good fit of the data to the proposed structure. No statistically significant correlation was found between the body mass index and each subscale or the total scale score. The translation and back-translation process yielded less than a 5% discrepancy between the versions.
