| Outline of Final Research Achievements |
A total of 151 university students were recruited for a follow-up cohort study conducted over four years. Their handwriting on the Uchida-Kraepelin test was analyzed using a digital pen with a temporal resolution of 13 ms. We extracted 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 a number and initiation of the next number (t2). The participants were classified into high and low risk groups according to the ratio of these time intervals (t1/t2). Students in the high-risk group in the first year had a strong tendency to remain in the same group during the next 3 years (odds ratio, 93.3). Moreover, first year participants in the high-risk group had a significant high risk of absences and leaving school during the 4 years of the study (odds ratio, 5.9). Thus, our results suggest that the ratio of this index is predictive of the risk of mental health disorders.
