The objective of this study is to test the efficacy of e-bibliotherapy on improving the psychological well-being of informal caregivers of people with dementia as compared with a control group.

This project is a two-arm randomized controlled trial evaluating the effects of e-bibliotherapy on improving the psychological well-being of informal caregivers of people with dementia. One hundred and ninety-two informal caregivers of people with dementia will be recruited. Participants in the intervention group will receive eight weekly e-bibliotherapy sessions. The control group will get access to the same e-bibliotherapy app but accept only general daily living knowledge. Psychological well-being, caregiving appraisal, mental health, biomarker of stress, and health-related quality of life will be measured to test the effects of e-bibliotherapy immediately post-intervention, three months post-intervention, and six months post-intervention. Focus group interviews will be conducted immediately post-intervention to explore caregivers' experiences participating in this study.
