The present study aims to investigate whether the psychometric results proposed by Sampén, Varela Diaz, Tello and Ortiz (2012) for the Spanish version of the scale of attitudes toward the elderly by Kogan (KAOP) are replicated. The total sample was of 1702 Mexican university students, with an average age of 20.70 years (SD = 1.93). The factorial structure of the questionnaire was analyzed through exploratory and confirmatory fac  tor analysis. The three-factor structure (personal sphere, social sphere and emotional sphere), based on statistical and substantive criteria, has shown adequate adjustment indicators of reliability and validity. However, the model does not match the obtained raised by Sampén et al. (2012). Future research should replicate these findings in larger samples.
