Abstract:
Objective:To explore the mediating effect of self-efficacy of family caregivers of dementia patients between patient-related impairment and caregivers' health-related quality of life.Methods:This study was a aross-sectional study. Using the convenient sampling method, family caregivers of dementia patients who accompanied patients in two ClassⅢ Grade A hospitals in Shanghai from December 2015 to September 2019 were selected as the research objects. Self-Efficacy Questionnaire for Chinese Family Caregivers (SEQCFC) , the MOS 36-item Short Form Health Survey (SF-36) and the Chinese Version of the Relevant Outcome Scale for Alzheimer's disease (CROSA) were used to conduct the questionnaire survey. SPSS 22.0 and AMOS 22.0 software were used for statistical analysis, Pearson correlation was used to calculate the correlation between variables and structural equation model was established to test the relationship between variables.Results:A total of 291 caregivers who met the inclusion criteria completed the questionnaire assessment, and the completion rate of the questionnaire was 100%. The impairment score of dementia patients was (87.13±23.88) , the total score of self-efficacy of care givers was (57.49±16.42) , the overall physical health score of health-related quality of life was (41.33±9.71) and the total score of mental health was (48.85±7.69) . The results of Pearson correlation analysis showed that in addition to the self-efficacy of the support dimension, the total score of the patients' dementia-related impairment was positively correlated with the total score of the caregivers' self-efficacy and the self-efficacy of the care giving behavior dimensions ( P< 0.05) . The total score of dementia-related impairment of patients was positively correlated with the total score of physical health and the total score of mental health of caregivers ( P<0.01) . The total score of caregivers' self-efficacy and the self-efficacy of each dimension of caregiving behavior were positively correlated with the total score of physical health and mental health of caregiver ( P<0.01) . Caregivers' self-efficacy was a partial mediator between dementia-related impairment and physical and mental health related quality of life of caregivers, and the mediation effect accounted for 29.79% and 43.67% of the total effect, respectively. Conclusions:The dementia-related damage of patients can directly affect the caregivers' health-related quality of life and it can also indirectly affect the caregivers' health-related quality of life through the caregivers' sense of self-efficacy. Therefore, it can reduce effects of dementia-related impairment on health-related quality of life of caregivers by improving caregivers' sense of self-efficacy.
