This study investigated the validation of the Japanese version of the 13-item Cognitive Fusion Questionnaire (CFQ) whose content was revised and the 7-item CFQ. Results of a survey of university students showed that the revised CFQ-13 reflects a two-factor structure, whereas the CFQ-7 reflects a one-factor structure similar to the previous study. Results of item analysis showed that treating each factor independently is appropriate. It was previously assumed that the two structures corresponded to "cognitive fusion" (Factor I) and "cognitive defusion" getting out of cognitive fusion (Factor II), respectively. However, results showed that Factor II corresponds to "a component of the function of defusion." Therefore, Factor I or the CFQ-7 is equivalent to cognitive fusion, and Factor II is appropriate to measure a part of defusion that is "the discrimination of self and thought." Moreover, the CFQ-13 requires an additional and different validation strategy by investigating the relationship with overt behavioral measurements in future studies.
