The work functioning impairment scale (WFun) was developed to measure the degree of work functioning impairment in Japanese workers based on the Rasch model. Given that the number of foreign workers employed in Japan and abroad has increased in recent years, a multilingual questionnaire is becoming increasingly necessary to investigate work functioning impairment in these workers. The purpose of this study was to verify the cross‐cultural validity of WFun between Japanese, Chinese, and English versions.
