Purpose
Evaluate the validity of the Opening Minds Scale (OMS) for nursing students via Rasch models and confirmatory factor analysis (CFA).
Design and methods
Undergraduate nursing student responses to OMS (n = 423). Validity was evaluated via CFA and Rasch analysis. Findings
CFA results were strongest for a three-factor 13-item version of OMS. Rasch modeling supported sound properties for two of three scales. Internal reliabilities ranged between 0.6 and 0.7.
Practice implications
OMS has potential as a valid measure for stigma research and antistigma program evaluation. Rasch analysis suggest it is inappropriate to use a total OMS score for nursing student populations.
