摘要：This study examined the test–retest reliability of the Japanese version of the Grit Scale. The Grit Scale was administered twice at two-month intervals to university and professional training school students. The correlation coefficients of each subscale of Grit between the two time points were r =.75 (consistency of interest) and r =.69 (persistence of effort; p s<.01), respectively. The correlation coefficient of the aggregate score of the Grit Scale between the two time points was also significant ( r =.77, p <.01). These results indicate that the Japanese version of the Grit Scale has a certain level of test–retest reliability.
