| Measure | Time frame |
|---|---|
| Amount of change in severity and burden of NPIQ delusional items before and after eye training in the group with delusions. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) To evaluate the differences in each saccade task in the group with delusions compared to the group without delusions. 2) To evaluate the effect of the intervention on the total score of Mini Mental State Examination, the time required for Trail Making Test A and B, the total score of Frontal Assessment Battery, the number of words produced in the word fluency task, and the total score of the shortened Japanese version of Zarit Caregiver Burden Scale before and after the eye training.
