Asian American multidimensional acculturation scale: development, factor analysis, reliability, and validity.

This article describes the development and psychometric properties of the Asian American Multidimensional Acculturation Scale (AAMAS). The results of 3 separate studies provide strong evidence of the instrument's reliability and validity. The principles for the development of the AAMAS were orthogonality of cultural dimensions, inclusion of a pan-ethnic Asian American dimension, and ease of use across ethnic groups. Exploratory and confirmatory factor analyses indicate that within each cultural dimension (AAMAS-Culture of Origin, AAMAS-Asian American, and AAMAS-European American) there are 4 reliable acculturation domains of cultural identity, language, cultural knowledge, and food consumption. These features of the AAMAS allow for a more complex assessment of acculturation level of Asian Americans and its relationship to psychological functioning.
