Abstract

The current study evaluated the psychometric properties of the newly developed Multi-Ethnic Acculturation Scale (MAS), a multidimensional instrument designed to assess behavioral and cognitive aspects of cultural adaptation among Hispanic/Latino individuals in the United States. A sample of 208 adults from diverse Hispanic backgrounds completed the MAS alongside two validated acculturation measures: the Short Acculturation Scale for Hispanics and the Vancouver Index of Acculturation. Exploratory factor analyses revealed a partially distinct but moderately correlated factor structure for both American and Latino cultural orientation subscales, supporting a bidimensional conceptualization of acculturation. Internal consistency was high across both subscales (Cronbach’s α > .90), and test-retest reliability demonstrated temporal stability. Regression analyses showed that proficiency and language dominance significantly predicted overall acculturation scores. Overall, these findings support the MAS as a reliable and valid tool for assessing acculturation across diverse Hispanic populations.
