Psychometric testing on two weight stigma instruments in Iran: Weight Self-Stigma Questionnaire and Weight Bias Internalized Scale.
Article in Eating and weight disorders : EWD, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 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
purposeThis study aimed to comprehensively and thoroughly examine the psychometric properties of two commonly used weight-related self-stigma instruments on Iranian adolescents with overweight or obesity: Weight Self-Stigma Questionnaire [WSSQ] and Weight Bias Internalization Scale [WBIS].
methodsAfter ensuring the linguistic validity of both the WSSQ and WBIS in their Persian versions, 737 Iranian adolescents with overweight or obesity (male = 354; mean age = 15.8 ± 1.3 years; body mass index = 30.0 ± 4.8 kg/m
resultsIn the scale level, the confirmatory factory analysis verified the two-factor structure for the WSSQ and the single-factor structure for the WBIS. The factorial structures were further found to be invariant across gender (male vs. female) and across weight status (overweight vs. obesity). Additionally, both the WSSQ and WBIS had promising properties in internal consistency, test-retest reliability, separation reliability, and separation index. In the item level, all items but WBIS item 1 (infit mean square = 1.68; outfit mean square = 1.60) had satisfactory properties in factor loadings, corrected item-total correlation, test-retest reliability, and infit and outfit mean square. Moreover, all the items did not display substantial differential item functioning (DIF) across gender and across weight status.
conclusionBoth the WSSQ and WBIS were valid instruments to assess the internalization of weight bias for Iranian adolescents with overweight or obesity. LEVEL OF EVIDENCE: Level V, cross-sectional descriptive study.
