Clinical Trial Summary

This study aims to establish the Senior Driving Simulation Training (SDST) for Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI), and explore the effectiveness of Senior Driving Simulation Training (SDST) on the executive function, cognitive function and EEG.


Description:

Driving behavior is a high cognitively demanding task, and whether the Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) can continue to drive is an important issue. This study will develop the Taiwan version of innovative, immediate feedback and environmentally safe Senior Driving Simulation Training (SDST). This study aims to establish the Senior Driving Simulation Training (SDST) for Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI), and explore the effectiveness of Senior Driving Simulation Training (SDST) on the executive function, cognitive function and EEG. The investigators intend to conduct a single-blind randomized controlled trial using a two-arm parallel-group design. Participants will be randomized by the permuted block randomization, block size of 4, into an experimental group (Senior Driving Simulation Training: 30-mins training session two times per week for 5 weeks, with a total of 10 sessions) or a control group (Waiting list). The investigators plan to blind the therapists and outcome assessors to maintain the blinding methods' quality. The primary outcome indicators are mental set-shifting, working memory, and inhibition. The secondary outcome indicators are cognitive function and EEG. The investigators also evaluate visual awareness and simulator sickness. The short-term (immediate post-test) and the long-term (3, 6, and 12 months) effectiveness of the intervention on individual outcome measures will be analyzed by the generalized estimating equation. The investigators also plan to use the secondary data analysis methods to investigate the relationship between objective indicators of a driving simulator, executive function, cognitive function, EEG, visual awareness, and simulator sickness. Furthermore, the investigators will analyze the trend of EEG while the participants conducting the training, and complete the psychometric properties of the Chinese version of the Cognitive Change Index (C-CCI). This will be the first senior driving simulation training (SDST) for Subjective Cognitive Decline (SCD) and Mild Cognitive Impairment (MCI) in Taiwan. Results of the current study will provide valuable information on driving safety decisions and apply to promote the advanced driving policies.

Type Measure Description Time frame Safety issue
Primary Mental set shifting, measured by Wisconsin Card Sorting Test Mental set shifting is one of the sub-categories of executive function immediate post-test
Primary Change from Baseline Mental set shifting, measured by Wisconsin Card Sorting Test at 3 months Mental set shifting is one of the sub-categories of executive function 3 months follow-up
Primary Working memory, measured by Digit span test Working memory is one of the sub-categories of executive function immediate post-test
Primary Change from Baseline Working memory, measured by Digit span test at 3 months Working memory is one of the sub-categories of executive function 3 months follow-up
Primary Inhibition, measured by the Stroop Color and Word Test Inhibition is one of the sub-categories of executive function immediate post-test
Primary Change from Baseline Inhibition, measured by the Stroop Color and Word Test at 3 months Inhibition is one of the sub-categories of executive function 3 months follow-up
Secondary Cognitive function measured by Montreal Cognitive Assessment Cognitive function measured by Montreal Cognitive Assessment immediate post-test
Secondary Cognitive function measured by Cognitive Change Index(C-CCI) Cognitive function measured by Cognitive Change Index(C-CCI) immediate post-test
Secondary Change from Baseline cognitive function by Montreal Cognitive Assessment at 3 months Change from Baseline cognitive function by Montreal Cognitive Assessment at 3 months 3 months follow-up
Secondary Change from Baseline cognitive function by Cognitive Change Index(C-CCI)at 3 months Change from Baseline cognitive function by Cognitive Change Index(C-CCI)at 3 months 3 months follow-up
Secondary EEG EEG power in delta, theta, alpha, and beta band immediate post-test
Secondary Change from Baseline EEG at 3 months EEG power in delta, theta, alpha, and beta band 3 months follow-up
Secondary Visual awareness measured by CANTAB Visual awareness measured by CANTAB immediate post-test
Secondary Visual awareness measured by trail making test Visual awareness measured by trail making test immediate post-test
Secondary Change from Baseline visual awareness by CANTAB at 3 months Visual awareness measured by CANTAB 3 months follow-up
Secondary Change from Baseline visual awareness by trail making test at 3 months Change from Baseline visual awareness by trail making test at 3 months 3 months follow-up
Secondary simulator sickness Simulator Sickness Questionnaire (SSQ). The 16-item SSQ will be used to assess participants' sickness levels. This is the 4-point Likert scale (0 - "None" to 3 - "Severe"), and the higher total score reflects more severe sickness. immediate post-test
Secondary Usability The System Usability Scale (SUS) will be used to access the usability, this scale consists of 10 items, and the higher total score reflects better usability. immediate post-test
Secondary Acceptance The Technology Acceptance for Older Adults Scale will be used to access the acceptance, this scale consists of 17 items, and the higher total score reflects better acceptance. immediate post-test
