This is a 8-week pilot randomized controlled trial utilizing bibliotherapy compared with usual care to investigate the feasibility and acceptability of bibliotherapy among informal caregivers of people with dementia in China, and preliminarily examine the efficacy on improving caregiving appraisal.

Background: China is one of the countries with the highest number of people with dementia (PWD), while over 90% of PWD are cared by informal caregivers in the community. Informal caregivers are found to have higher level of stress, and lower level of well-being than non-caregivers. However, positive outcomes of caregiving have also been noted. Caregiving appraisal is caregivers' cognitive evaluation of potential caregiving stressors and the efficacy of their coping efforts related to caregiving experience. Based on Lawton's Caregiving Appraisal and Psychological Well-being Model, caregiving appraisal is an important factor that leads to the positive or negative well-being outcomes of caregivers. Addressing the caregiving appraisal of informal caregiver may be able to help in promoting the caregiver well-being and delay premature institutionalization. Intervention for improving dementia caregiving appraisal is still scarce, especially in China. Bibliotherapy is the process of learning from high-quality written materials for therapeutic benefits, it has been proved to be effective in improving caregiving appraisal of informal caregivers of people with psychosis and depression, its effect on dementia caregivers is unsure.

Objectives: There are two research objectives in this study: (1) To determine the feasibility and acceptability of the evidence-based bibliotherapy protocol among informal caregivers of PWD in China. (2) To preliminarily explore the efficacy of bibliotherapy on improving caregiving appraisal.

Methods:

Sixty participants will be recruited from Zhengzhou, China, and will be randomly allocated to either the intervention group or usual care group. The feasibility of the intervention will be explored in terms of the ease of participant recruitment, attendance rate and the attrition rate. The acceptability will be explored by interviews of participants in the intervention group at post-intervention. The Chinese version of Caregiving Appraisal Scale, the Chinese version of Ways of Coping Questionnaire, the Chinese version of Positive Aspects of Caregiving Scale, the Chinese version of Ryff's Psychological Well-being Scale, Alzheimer's Disease Knowledge Scale and Dementia Attitude Scale will be used to measure caregiving appraisal, coping, positive aspects of caregiving, psychological well-being, knowledge of dementia and attitude toward dementia of informal caregivers of PWD respectively. Descriptive statistics, Chi-square test, Mann Whitney U test, and independent t-test will be used to describe the participants' characteristics and compare the difference between groups at baseline. GEE will be used to examine the intervention efficacy.
