Dementia Care Research and Psychosocial Factors

Area of Science:

• Gerontology
• Human-Computer Interaction
• Transportation Safety

Background:

• Dementia can impair driving ability, necessitating safe monitoring solutions.
• GPS-based Driving Monitoring Systems (DMS) are emerging tools for assessing driving in individuals with cognitive impairments.
• Understanding the acceptability and usability of DMS is crucial for their effective implementation.

Purpose of the Study:

• To assess the usability and acceptability of DMS in older adults.
• To compare DMS perception between cognitively intact older adults and those with mild cognitive impairment (MCI).

Main Methods:

• A DMS was installed in the vehicles of 13 participants (9 controls, 4 with MCI) for 8 weeks.
• Participants completed a user acceptance questionnaire assessing perceived usefulness, privacy, comfort, and facilitating conditions.
• Data were analyzed using descriptive statistics (median, IQR) and Mann-Whitney U tests for group comparisons.

Main Results:

• Both groups reported high comfort and minimal perceived interference from the DMS.
• Privacy concerns were low, though slightly higher than comfort ratings.
• Perceived usefulness varied, indicating uncertainty about the technology's benefits.
• Participants with MCI reported less perceived limitation on their driving compared to controls.

Conclusions:

• DMS technology appears acceptable and potentially useful for older adults, including those with MCI.
• Further research with larger samples is needed to explore factors influencing DMS acceptance and usability.
• DMS can be a valuable tool for monitoring driving patterns in aging populations.
