한국판 비합리적 수행신념 척도(iPBIK) 타당화 연구

Abstract

Objectives The purposes of this study were to develop and validate the original British version of the 28 items iPBI as a Korean version (iPBIK) reflecting the Korean language and culture. The irrational Performance Beliefs Inventory (iPBI) is a scale which was developed based on Ellis' modern rational emotive behavior therapy (REBT) theory to measure irrational beliefs in performance environments such as achievement and failure. Methods 296 former and current teachers in Seoul and Gyeonggi-do were tested for translated irrational performance beliefs inventory(iPBI), general attitude and belief scale of korean version(GABS-K), and Stress Emotions Scale by online surveys. Based on the collected data, exploratory factor analysis and confirmatory factor analysis for iPBI were conducted in parallel. For statistical analysis, SPSS 29.0 and AMOS 29.0 programs were used. Results As a result of exploratory factor analysis, 28 items of the four-factor structure of the primary irrational belief, the low frustration tolerance, the awfulizing, and the depreciation were identified. In the first confirmatory factor analysis using Structural Equation Modeling(SEM), eight items with low standard regression coefficients were identified. A second confirmatory factor analysis was conducted to select 20 items of iPBIK as the final model. It was confirmed that the model fit was improved by allowing error term variance. Conclusions iPBIK showed high positive correlation with the conventional irrational belief scale, the General Attitude and Belief Scale (GABS-K), and also with the Stress Emotions Scale that measures anxiety, depression, and anger, proving its validity. In addition, internal consistency was also found to be high, and iPBIK was supported as a reliable and reasonable measure. These findings suggest that members' irrational beliefs in performance settings such as work place, military, sports, and schools reflect cognitive vulnerabilities related to emotional stress, and iPBIK can be used as a useful tool to evaluate these irrational beliefs.
