The present study was part of a series of attempts to adapt the State-Trait Anger Expression Inventory in Korea (STAXI-K). Particularly, the fifth stage of the STAXI-K was conducted and reported in the present study. Participants were 1200 college students representative of major areas in Korea. Major findings in the present study include: (1) Factor analyses revealed the same factor structures to the original English STAXI (Spielberger, 1988). These findings were obtained, however, only after four indigenous items were substituted for problematic items in the STAXI; (2) Reliability check revealed Cronbach alpha higher than .70. One exception, however, was found for the anger-in scale for the female sample (.62). (3) When test-retest reliabilities for a three week period were calculated, all scales were satisfactory, trait anger (r=.81), anger-in (r=.67), anger-out (r=.71), and anger- control (r=.82), except state anger (r=.14). The low test-retest reliability for state anger, however, was consistent with the concept that state anger would be unstable in contrast to an stability of the trait anger. (4) When correlations were calculated among scales of the STAXI, there was some degree of association between anger-in and anger-out (.24), implying that these two scales may not be orthogonal. Finally, implications of the present findings for future studies are suggested.
