Measurement invariance of HIV-related stigma scales among men who have sex with men (MSM) and non-MSM populations: implications for comparative studies in China.
Article in Frontiers in psychology, 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
Background: Measurement invariance ensures that scales used in research measure the same constructs across different groups. As HIV-related stigma scales are increasingly used in studies involving men who have sex with men (MSM) and non-MSM populations, it is crucial to evaluate the equivalence of these measures. This study examines the measurement invariance of internalized, anticipated, and enacted HIV-related stigma scales between MSM and non-MSM populations in China. Methods: Data were derived from two studies: a prospective cohort study with 193 MSM and 579 non-MSM, and a cross-sectional survey of 402 MSM. Participants completed the 8-item internalized, 9-item anticipated, and 16-item enacted HIV-related stigma scales. Confirmatory factor analysis was used to test measurement invariance by progressively adding equality constraints to the models for each stigma dimension. Results: Partial scalar measurement invariance was achieved for the internalized stigma scale, allowing the intercepts of items 2, 3, and 6 to vary (χ Conclusion: The study supports the use of these HIV-related stigma scales for comparing MSM and non-MSM populations, though caution is needed as some items demonstrated partial measurement invariance. These findings provide a foundation for future research and interventions aimed at reducing HIV-related stigma across diverse groups.
