Influence of dementia literacy and caregiving appraisal on the psychological wellbeing of informal caregivers of people with dementia: A cross-sectional study.

Background: Dementia informal caregiving is a global phenomenon. It is well documented that caregivers' psychological health is often affected by busy caregiving schedules. Lawton's two-factor model indicates that caregivers' psychological wellbeing is influenced by caregiving appraisal and other caregiver factors. Our review also identified the significance of dementia literacy, which was an essential caregiver factor. However, it is imperative for a clear understanding of the mechanism of how psychological wellbeing is influenced by them. Objectives: To explore the association among dementia literacy, caregiving appraisal, and psychological wellbeing and the influencing mechanisms between them. Methods: Two hundred and twenty-three informal caregivers of people with dementia were involved in this cross-sectional study. Dementia literacy was measured by the Alzheimer's Disease Knowledge Scale and Dementia Attitude Scale. Caregiving appraisal and psychological wellbeing were measured with the Caregiving Appraisal Scale and Ryff's Psychological wellbeing Scale, respectively. Descriptive statistics were used to describe the characteristics of participants and key outcome variables. Pearson's correlation analysis was used to analyze the correlation among the variables. Structural equation modeling was used to examine the hypothetical mediating role of caregiving appraisal in the relationship between dementia literacy (i.e., knowledge of dementia and attitude toward dementia) and caregivers' psychological wellbeing. Results: The hypotheses were partially confirmed. Attitude toward dementia was significantly associated with caregiving appraisal ( Conclusion: Efforts can be exerted to improve dementia caregivers' caregiving appraisal and attitude toward dementia to improve their psychological wellbeing.
