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

我们调查了内田-克雷佩林测试是否可以作为一种方法来预测心理健康障碍使用的笔迹，这是使用数字笔获得。总共招募了166名学生进行了3次以上的随访队列研究（每年4月初一次）。参与者完成了Uchida-Kraepelin测试和问卷GHQ 30。我们分析了数字的第一和第二笔之间的时间间隔（4，5和7;平均时间间隔：t1）和完成书写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比值与GHQ 30社交功能障碍评分之间存在相关性（p < 0.05）。高危组（t2/t1 > 11组）的脱落率是低危组（t2/t1 < 11组）的10倍（p < 0.01）。这些结果表明，使用t2/t1比率预测心理健康障碍是可能的。

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.
