The Modified Weight Bias Internalization Scale: measurement invariance by weight status and race among undergraduate women
Authors' conclusion
This may inform future studies that wish to utilize the WBIS-M, such as investigations of mean level differences in internalized weight bias. These findings may have clinical applications in the treatment and prevention of obesity, given the heightened levels of internalized weight bias and weight-based discrimination faced by individuals with higher body weights.
Study context
- Population
- Racially/ethnically diverse undergraduate women across the weight spectrum (24.9% with overweight/obesity)
- Participants
- 746 women
- Exposure
- WBIS-M measurement invariance across weight status and race
- Outcome
- Metric, threshold and scalar invariance of the 11-item WBIS-M (ΔCFI ≤ −0.010, ΔRMSEA ≤ 0.015, ΔSRMR ≤ 0.030)
Methodological detailsmeasurement invariance analysis, confirmatory factor analysis

Main finding
As reported in the abstract
Measurement invariance of WBIS-M
- WBIS-M showed invariance across weight status and racial groups
- Each CFA model showed good to excellent descriptive model fit
Observational data: associations, not effects.
