Psychometric properties of the weight self-stigma questionnaire and weight bias internalization scale in postpartum women.
Article in BMC pregnancy and childbirth, 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
backgroundWeight stigma internalization among postpartum women may differ from other populations owing to childbirth, breastfeeding, and postnatal physical recovery. Two instruments to assess the concept of weight stigma internalization-the Weight Self-Stigma Questionnaire (WSSQ) and the Weight Bias Internalization Scale (WBIS)-have not been validated in postpartum women. This study aims to evaluate and compare the reliability, factor structure, and concurrent validity between the WBIS and WSSQ in Chinese postpartum women.
methodsA total of 476 postpartum women (mean age 30.96 ± 4.67 years) completed the WSSQ and WBIS, as well as other relevant measures regarding perceived weight stigma, psychological outcomes, and eating behaviors. Height and weight were used to calculate the body mass index (BMI). Statistical analyses were performed using internal consistency analysis, confirmatory factor analysis, and correlation analysis.
resultsBoth the WSSQ and the WBIS were found to have excellent internal consistency. In addition, both were associated with postpartum BMI, perceived weight stigma, adverse psychological outcomes, and restrained and emotional eating behaviors. Differently, the two-factor structure of the WSSQ was supported among postpartum women, but the one-factor WBIS was not.
conclusionThe WSSQ is a reliable and valid measurement tool for assessing weight stigma internalization in postpartum women. The structure of WBIS requires further validation and modification in future research.
