A Japanese version of Thought-Shape Fusion Scale (TSFS) that assesses cognitive distortions associated with eating pathology was developed. This distortion is said to occur when merely thinking about eating a forbidden food increases the person痴 estimate of their shape and weight, elicits a perception of moral wrongdoing and makes the person feel fat (Shafran et al., 1999). Japanese participants (n342) completed the Japanese version of the TSFS, along with Japanese version of Thought泡ction Fusion Scale, which already had reliability and validity data, several subscales of Eating Attitude Test, Eating Disorder Inventory, and Self-rating Depression Scale. Results confirmed that Japanese version of the TSFS had good reliability and construct validity. It was concluded that the scale was a useful tool for investigating eating related cognitions in Japanese people.
Key words: Thought-Shape Fusion, Thought-Action Fusion, Japanese version, eating disorders
