Validation of a core beliefs model of disordered eating in adults with an eating disorder.
Article in Eating and weight disorders : EWD, 2025. 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
purposeThis study aimed to validate a core beliefs model of disordered eating in a sample of adults with a current eating disorder diagnosis. This model outlines important processes and pathways from maladaptive eating disorder core beliefs to dietary restraint, objective binge eating and compensatory behaviours.
methodsParticipants were adults (N = 232) living in English-speaking countries who self-reported having a current eating disorder diagnosis given by a healthcare professional. Preliminary analyses included examining correlations between included variables and internal consistency. Path analysis was conducted in R to test the core beliefs model.
resultsThe original model demonstrated poor to acceptable fit to the observed data. Minor modifications were utilised to remove non-significant paths to improve fit, including the removal of 'perfectionism' as a mediating variable in the model. The final modified model indicated acceptable model fit. This model demonstrates specific pathways that maladaptive core beliefs contribute to the development of dietary restraint, objective binge eating and compensatory behaviours, through either increased pre-occupation with eating, weight and shape, or through increased negative affect, emotional dysregulation and meta-cognitive beliefs about binge eating.
conclusionsThe present study provides partial validation of a core beliefs model of disordered eating and extends the current understanding of how maladaptive core beliefs may impact the development of key disordered eating symptomatology. LEVEL OF EVIDENCE: IV.
