Abstract

OBJECTIVES: The purpose of present study was to evaluate reliability and validity of Korean version of State-Trait Anger Expression Inventory(STAXI).
METHODS
We applied to 416 second graders of middle and high school students, and 35 clinical conduct disorder subjects. Test-retest reliability test was done to 60 subjects with 4 weeks interval. To evaluate concurrent validity, aggression subscore of Achenbach's CBCL and Barratt's Impulsiveness Scale were also applied.
RESULTS
The results were as follows. 1)Test-retest reliability, item-total correlation, and internal consistency were very satisfactory and concurrent validity with other scales was also good. 2)Anger expression scores were significantly increased by aging and males showed significantly higher scores than females. 3)Clinical population scored significantly higher than general population group in the level of anger expression. 4)In factror analysis, item composition of factors were somewhat different from those of original scales.
CONCLUSION
The Korean version STAXI is validated and can be used usefully as evaluating anger of clinical adolescent population. Further research is needed for standardization in general population and clinical referred subjects. Finally, transcultural study should follow to find out difference of anger expression.
