Predicting mental health disorders based on the time intervals between strokes while writing numbers

我们调查了内田-克拉佩林测试是否可以作为一种预测精神健康障碍的方法，使用使用数字笔获得的笔迹。总共招募了166名学生进行为期3次的跟踪队列研究(每年4月初进行一次)。参与者完成了内田-克拉佩林测试和一份GHQ30问卷。我们分析了数字第一次和第二次笔划之间的时间间隔(4，5和7；平均时间间隔：T1)，以及从写完一个数字到开始写下一个数字之间的时间间隔(平均时间间隔：T2)。T2/T1比率与GHQ30的社会功能障碍评分之间存在相关性(p&lt；0.05)。此外，高风险组(T2/T1和11)的辍学率是低风险组(T2/T1和11；P&lt；0.01)的10倍。这些结果表明，使用T2/T1比率来预测精神健康障碍是可能的。

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.
