We presented a view of the conceptual and theoretical framework of anger and hostility that guided the construction of the State-Trait Anger Expression Inventory (STAXI). The goal of this study was to report the final selection and adaptation of the 44 items that comprise the Multicultural Latin American Anger Expression Inventory (ML-STAXI). In keeping with the conceptual definitions of stage-anger, trait-anger, and anger expression and control, new items were also constructed to replace those containing English idiomatic expressions. Utilizing a multicultural Latin American population sample, responses to the items, were factored by principal factor analysis with promax rotations to determine the level of correspondence of factor structure between these two instruments. The analyses substantially verified the factor structure of the ML-STAXI previously found in a Latin American sample. The ML-STAXI presents with empirical evidence that demonstrates a high degree of construct validity and internal consistency as shown by its factorial structure and alpha correlations.
