Development and validation of the Thoughts on Eating Scale: a domain-specific measure of belief orientations toward eating.
Article in BMC psychology, 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
backgroundUnderstanding individual differences in eating behavior is a central challenge in psychological research. Because broad traits show only weak-to-moderate links to eating, and most measures focus on behavioral outcomes, belief-level, domain-specific constructs connecting global traits to situation-specific behaviors have not been a primary focus of existing measurement approaches. This study introduces and empirically validates "Thoughts on Eating" (ToE) as a domain-specific belief system positioned between stable personality traits and specific eating behaviors.
methodsWe conducted two sequential studies with Japanese adults. In Phase 1, we collected free-text responses from 100 participants to generate candidate items, then administered the resulting scale to a stratified sample of 552 adults to identify the dimensional structure of ToE through exploratory and confirmatory factor analyses. In Phase 2, we examined test-retest reliability and concurrent validity using the Expanded Mindful Eating Scale (EMES) and the Dutch Eating Behavior Questionnaire (DEBQ) in a follow-up sample of 434 participants.
resultsExploratory and confirmatory analyses supported seven factors: "Enriching One's Heart," "Encouraging Social Communication," "Realizing Oneself," "Sustaining Oneself," "Respecting Food," "Indifference to Eating," and "Disliking Eating." The latter two represent fundamental evaluative orientations that are not well captured by most existing eating-related measures. The scale demonstrated adequate temporal stability and theoretically coherent associations with established measures. Associations with demographic variables and eating behaviors indicated that ToE is shaped by the intersection of individual characteristics and sociocultural contexts, supporting its characterization as an intermediate-level construct that is more stable than situational attitudes yet more context-sensitive than global traits.
conclusionsOur findings establish that ToE is a theoretically sound construct that reflects belief orientations that have received limited systematic attention in individual-differences research on eating. This study proposes a multi-level structure as a foundation for integrating personality, social, cultural, and clinical psychology perspectives, which is expected to advance our understanding of individual differences in eating behavior.
