This study is intended to examine the influence of Dichotomous Thinking(DT) on psychopathology, comparing three different DT scales. With 480 college students, scores of DTI-30R, DTI, DTEDS-11, PAI-BOR, KEAT-26, HMPS were surveyed. This study compared three different DT scales such as Revised Dichotomous Thinking Index-30(DTI-30R; Seong-Hoon Hwang, 2007), Dichotomous Thinking Inventory(DTI; Oshio, 2009) and Dichotomous Thinking in Eating Disorders Scale-11(DTEDS-11; Byrne, Cooper, & Fairburn, 2007). The comparison suggested that the correlation of the three scales was high by r=.574~.632, but the partial correlation was low by r=.304~.434. In addition, we used the regression analysis in order to learn which of the three scales is the most correct in predicting borderline tendency, eating disorder, positive perfectionism and negative perfectionism. As a result, the explanatory power of DTI-30R was high in case of pathological, maladjusted, and dysfunctional psychopathology like borderline tendency, and negative perfectionism. On the other hand, the explanatory power of DTI was high in case of less pathological, adaptive, and functional area like positive perfectionism, and that of DTEDS-11 was high in case of eating disorder. Lastly, implications and limitations of this study were discussed and suggestions for further research were proposed.
