Time anxiety seems to be a reflection of uncontrollability about the flow of time. From this point of view, we attempted to construct the scale which could be able to measure the degree of time anxiety. In our study, time anxiety scale was consisted of two sub-scale, namely, anxiety scale and irritation scale. Each of them had 10 question items. The factorial validity and reliability of this scale were highly enough to use for mesurement of time anxiety. By using this scale, we compared the degrees of time anxiety among the three groups, American and Japanese undergraduates, and Jananese businessman. The results were as follows. (1) On the anxiey scale, the score of Japanese studentsand people on the job were significantly higher than that of American students. (2) There were no difference among the scores of three groups on the irritation scale. These results suggested that the differences of time anxiety between Japanese and American could be observed not only on the strength but also on the characteristics of quality.
