한국판 상태-특성 분노 표현 척도 2판 개발 연구

초록

The aim of this study was to develop the Korean adaptation of the State-Trait Anger Expression Inventory-2 (STAXI-2), which is designed to measure state anger (15 items), trait anger (10 items), anger expression-in (8 items), anger expression-out (8 items), anger control-in (8 items), and anger control-out (8 items). An attempt was made to construct a pilot scale based on a variety of resources (e.g., the STAXI-2, open-ended questionnaire on anger, existing anger scales, literature review on anger, and the Korean adaptation of the STAXI). In Study 1, we examined the psychometric properties of the pilot scale in an adult sample nationwide (N = 718). Exploratory factor analyses and item-total correlations showed clear-cut factors for the experience of anger: state anger and trait anger. With respect to anger expression, however, factor analyses resulted in loss of many items from the pilot scale. Thus, we deleted the inappropriate items and included new items, resulting in 110 items for the second pilot scale. In Study 2, we examined the psychometric properties of the second version of the Korean adaptation of the STAXI-2 in an adult sample nationwide (N = 806). Exploratory factor analyses showed clear-cut factors not only for the anger experience (i.e., state anger and trait anger), but also for the anger expression (i.e., anger expression-in, anger expression-out, anger control-in, and anger control-out). Internal consistencies of the subscales revealed a satisfactory level of reliability. Additional analyses with correlation analyses and t-test also supported the validity of the STAXI-2. In conclusion, our results provided support for the reliability and validity of the Korean adaptation of the STAXI-2, suggesting that the Korean adaptation of the STAXI-2 is a useful instrument in the fields of psychology, medicine, nursing, education, coaching, organization, and criminal justice.
