Using a quantitative methodology with inferential analysis and second-generation techniques, the study verified the factorial structure and psychometric properties of the BSAUS. Cross-sectional surveys were conducted with 1,347 students from the Universities of Valladolid, Lleida, and Zaragoza between 2018/19 and 2022/23. Confirmatory factor analysis revealed Cronbach's alpha values of 0.76 and 0.74 for the Ageism construct, while Wellbeing, Behavioural, and Personality dimensions scored 0.70–0.66, 0.55, and 0.58–0.60, respectively. Composite reliability exceeded the 0.7 criterion across measures. The BSAUS, comprising three dimensions, is validated as a reliable tool for assessing discrimination, prejudices, and stereotypes towards older adults in university contexts. This scale has potential for ageism reduction initiatives and can inform strategies to prevent discriminatory behaviour towards older adults. info:eu-repo/grantAgreement/ES/DGA/B53-23R info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Urcola-Pardo, Fernando Universidad de Zaragoza (orcid)0000-0001-7049-8295 Llorente-Alonso, Marta Navas-Ferrer, Carlos Universidad de Zaragoza (orcid)0000-0003-2887-7835 Laborda-Higes, Fátima María Blázquez-Ornat, Isabel Universidad de Zaragoza (orcid)0000-0002-8197-9884 Jiménez-Navascués, Lourdes 1006 255 Universidad de Zaragoza Dpto.
