项目摘要

We investigated whether the Uchida-Kraepelin test could serve as a method for predicting mental health disorders using the handwriting which was acquired using a digital pen. In total, 166 students were recruited for a follow-up cohort study conducted over 3 times (once per year in early April). The participants completed the Uchida-Kraepelin test and a questionnaire GHQ30. We analyzed the time intervals between the first and second stroke of a number (4, 5, and 7; mean time interval: t1) and those between the completion of writing a number and initiation of writing the next number (mean time interval: t2). A correlation was observed between the t2/t1 ratio and social dysfunction scores on GHQ30 (p < 0.05). Furthermore, the dropout rate of the high-risk group (the group with t2/t1 > 11) was ten times higher than that of the low-risk group (the group with t2/t1 < 11; p < 0.01). These results suggest that it may be possible to predict mental health disorders using the t2/t1 ratio.

我们研究了内田-克雷佩林测试是否可以作为一种利用数字笔获得的笔迹来预测心理健康障碍的方法。总共招募了 166 名学生进行超过 3 次的后续队列研究（每年 4 月初一次）。参与者完成了 Uchida-Kraepelin 测试和 GHQ30 问卷。我们分析了第一次和第二次敲击数字之间的时间间隔（4、5和7；平均时间间隔：t1）以及完成书写一个数字和开始书写下一个数字之间的时间间隔（平均时间间隔：t2）。观察到 t2/t1 比率与 GHQ30 社交功能障碍评分之间存在相关性 (p < 0.05)。此外，高风险组（t2/t1 > 11 组）的退出率是低风险组（t2/t1 < 11 组；p < 0.01）的十倍。这些结果表明，使用 t2/t1 比率来预测心理健康障碍是可能的。
