Abstract
|
|
|
Background: This study aimed to validate the Korean adaptation of the State-Trait Anger Expression Inventory-2 (K-STAXI-2).
Methods: The study included a sample of 307 normal adults and 81 comparable adult patients. The data were analyzed using factor analyses, internal consistency measures, assessments of convergent and discriminant validity, t-tests between groups, and test-retest reliability.
Results: (1) Exploratory factor analyses revealed clear-cut factors for anger experience (state anger and trait anger) and anger expression (anger expression-in, anger expression-out, anger control-in, and anger control-out); (2) correlation analyses between K-STAXI-2 and the Emotional Stress Inventory demonstrated convergent and discriminant validity; (3) t-test between the patient group and the normal adults group provided additional construct validity; (4) internal consistencies of the six subscales showed a satisfactory level of reliability (α=.81 to α=.94); and (5) test-retest reliability over four weeks showed a satisfactory level of reliability.
Conclusions: The results further support the reliability and validity of the K-STAXI-2, suggesting its usefulness in various fields such as medicine, nursing, psychology, addiction, organization, education, and criminal justice.
