Abstract	This project tested the State-Trait Anger Expression Inventory—2 (STAXI-2) and the Novaco Anger Scale—Provocation Inventory (NAS-PI) in a sample of U.S. Hispanic ( n = 257) and U.S. non-Hispanic White (n = 246) undergraduate students. Internal consistency, subscale correlations, convergent validity with the Multidimensional Anger Inventory (MAI), and predictive validity were all analyzed. Across ethnic groups, all major subscales demonstrated adequate internal consistency reliability. Correlations between the subscales were strong for both groups within each measure and with the subscales of the other measure. In predicting PI scores, there was no evidence of intercept invariance across the ethnic groups and no evidence of slope invariance when either measure was used as a predictor. Results suggest that both measures are valid for use in Hispanic samples.
