The development of the 29-item Asian American Racism-Related Stress Inventory (AARRSI) is presented. In the first study, data from 161 Asian American respondents were subjected to an exploratory factor analysis, which yielded 3 subscales composed of Socio-Historical Racism (14 items), General Racism (8 items), and Perpetual Foreigner Racism (7 items). The data also revealed initial evidence of AARRSI's reliability and concurrent and discriminant validity. In the second study, data from 142 Asian American respondents were subjected to a confirmatory factor analysis, which provided support for the factor structure derived from the first study. Additional evidence of AARRSI's reliability and concurrent and discriminant validity were also found. In the third study, data from 38 Asian American respondents yielded evidence of AARRSI's test-retest reliability.
