简要总结
The goal of this clinical trial is to learn if a computerized eye-tracking training program can improve mental health and thinking skills in older adults. The main questions it aims to answer are whether eye-tracking training can lower depressive and anxiety symptoms in older adults, and whether it can improve their ability to control impulses and pay attention.
Researchers will compare older adults who receive eye-tracking training to older adults on a waitlist to see if eye-tracking training leads to greater improvements in mood and thinking skills.
Researchers will randomly assign participants into the experimental group or the waitlist control group. Participants in the experimental group will take part in eye-tracking training three times a week for 18 sessions, over about 1.5 months. Before and after training, participants will answer questions about their mood and take tests of memory, attention, and impulse control. Older adults on the waitlist will complete the same tests but will not receive training until after the study period; they will be offered the same training once their waiting period ends.

结局指标
主要结局
Inhibitory control
时间窗: Baseline and after completion of 18 training sessions (approximately 9 weeks)
Inhibitory Control Index (ICI) in the Eriksen Flanker Test
Sustained attention
时间窗: Baseline and after completion of 18 training sessions (approximately 9 weeks)
Digit Cancellation Index (DCI) in the Digit Cancellation Test
Depressive symptoms
时间窗: Baseline and after completion of 18 training sessions (approximately 9 weeks)
Depressive symptoms are assessed using the 15-item Chinese version of Geriatric Depressive Scale (CGDS-15). It is a 15-item self-report scale in which participants answer "Yes" or "No" to whether they experienced each of 15 common depressive symptoms in the past week. Scores range from 0 to 15, with higher scores indicating more depressive symptoms. A score of 8 or higher indicates clinically significant depressive symptoms.
Anxiety symptoms
时间窗: Baseline and after completion of 18 training sessions (approximately 9 weeks)
Anxiety symptoms are assessed using the 10-item Chinese version of Geriatric Anxiety Scale (CGAS-10). It is a 10-item self-report measure of anxiety symptoms in older adults. Higher scores indicate greater severity of anxiety symptoms.
