The validation of the Barcelona Orthorexia Scale-Spanish version: evidence from the general population.
Article in Eating and weight disorders : EWD, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo validate the Spanish version of Barcelona Orthorexia Scale (BOS) in general population, analyzing its items and both its internal structure and psychometric properties (internal consistency and temporal stability). In addition, the relationship between ON and external measures of attitudes towards food was assessed.
methodThe general population sample consisted of 446 women and 104 men, aged between 18.31 and 69.44 years (M = 36.03; SD = 12.46). Of these, 39 participants answered again the questionnaires after one month from the first application. The assessment instruments were a sociodemographic questionnaire, the BOS, the Eating Attitudes Test-26 (EAT-26) and the Dutch Eating Behavior Questionnaire (DEBQ).
resultsThe final version of the BOS is composed of 35 items. Exploratory factor analysis extracted an internal structure of 5 factors (Behavioral, Concern for healthy food, Attitudes and beliefs about food, Vital achievement and Emotional discomfort). The BOS-35 and the factors presented good internal consistency (α = .80-.90), and an adequate temporal stability (r = .62-.88). The highest association was observed between the Emotional Distress (BOS) and the Diet subscale (EAT-26; r = .51).
conclusionsThis first validation of the BOS has shown adequate psychometric properties, being a valid and reliable instrument to assess ON in the general population. Level of evidence Level II: Evidence obtained from well-designed controlled trials without randomization.
