E-bibliotherapy app is the first of it’s kind application designed specifically for informal caregivers of individuals with dementia. The content of this application is based on seven years of research conducted by the research team and includes a wealth of real-life cases. Its purpose is to assist caregivers in acquiring disease information and health knowledge through reading, learning caregiving skills and strategies, obtaining psychological guidance and emotional management techniques, and ultimately improving their mental well-being. The application allows caregivers to learn systematically through reading and watching, and enables them to create personalized plans anytime, anywhere. Compared to traditional face-to-face interventions, it is more cost-effective. As the application primarily supports caregivers through self-help, it has the potential to alleviate the burden on caregivers and reduce healthcare costs associated with managing dementia in the community.
