Assessment of self-reported anger expression in pre- and early-adolescent African Americans: psychometric considerations.

This study examined the psychometric properties of the Speilberger state-trait anger expression inventory (STAXI) and Framingham (FAS) anger scales in 86 African American youth. Significant gender differences were not observed for the STAXI or FAS subscales scores (all p>0.17). Inter-scale correlations revealed that the anger-in and anger-out subscales of the STAXI and FAS were measuring similar, yet different constructs. For the STAXI, intra-scale correlations indicated that the anger-in and anger-out subscales were not independent (p<0.001), whereas the anger-in and anger-out subscales (FAS) were not statistically related (p>0.05). The component structures for the anger-control subscale (STAXI) and the anger subscales (FAS) were similar to those reported by the scale authors.
