Measuring anticipated stigma towards irritable bowel syndrome (IBS) in the German general population: testing the applicability of a modified version of the Perceived Stigma Scale of IBS in the cross-sectional SOMA.SOC study.
Article in BMJ open, 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
objectiveThere is only a little research on anticipated stigma in the general population, despite evidence of negative consequences with regard to underutilisation of medical testing or treatment. While a lot of instruments focus on the interpersonal dimension of public stigma (i.e., societal attitudes), fewer assess the intrapersonal dimension of anticipated stigma, a belief that stigmatising attitudes will be directed at the self in the future. The objective of this study was to test the applicability and the psychometric properties of an anticipated stigma scale in a population survey on beliefs about irritable bowel syndrome (IBS).
methodsAnalyses are based on telephone interviews in a random population sample of 1205 adult individuals in Germany. They were presented with a vignette describing a person with symptoms suggestive of IBS, followed by 10 items assessing anticipated stigma based on a modified version of the Perceived Stigma Scale of IBS.
resultsResults indicate that individuals expected others not to have enough knowledge about symptoms and may ascribe their aetiology to personal behaviour. A first exploratory factor analysis (EFA) yielded two factors. Examination of scree plot and content considerations justified a second EFA specifying a one-factorial solution with Cronbach's α of 0.80 and satisfactory discriminatory power and mean inter-item correlations.
conclusionThe applicability of the scale to assess anticipated IBS stigma in the general population using a vignette design was demonstrated. Such assessments can be used as the basis for tailored anti-stigma measures, for example, the communication of specific facts about the development of IBS symptoms.
