Objective: To test appropriateness of writing subtest translated into Korean. Method: Fourty-five students participated in this study. The time spent on each sentence was measured for both hand. We performed Repeated Measure as a statistical analysis. Results: When the averaged time spent on each sentence was compared, the second and the fourth sentences were longer than the first and the third sentences. There were significant differences in the time spent to write each sentences with nondominant hand, but not with dominant hand. For the nondominant hand, the result of contrast test had significant differences in the first, second, third sentences, but not in the fourth sentence. Conclusions: There was significant difference in the time spent in writing the four sentences. Because equivalent time duration represents the validity of Jebsen-Taylor Hand Function Test, a modification of the test is recommended.
