"Monitoring Everyday Life in Aging & Dementia - Perspectives from Experience Sampling and Technology Use"

This dissertation aims to improve the understanding and management of everyday life in older adults by using smartphone-based digital diaries and other eHealth solutions. Technology use can be challenging for older adults, particularly when dealing with cognitive dysfunctions. Therefore, the feasibility and usability of digital diaries is tested in people with mild cognitive impairment. Results show that most participants can use digital diaries well and enjoy repeatedly filling in short questionnaires concerning their current mood, activities, and context. Furthermore, cognitive tasks can be integrated in digital diaries to measure fluctuations of attention or memory. Digital diaries are not used often in older adults yet, but show promise to improve well-being through self-monitoring, can stimulate self-awareness, and behavioural changes towards more positive and meaningful activities.
