The informal care providers of individuals with dementia often encounter various challenges, including physical, emotional, and financial difficulties, due to the complex nature of the illness. Chronic stress frequently results in physical manifestations, such as psychosomatic symptoms. In light of the caregiving burden, researchers are increasingly focused on assisting caregivers in alleviating this burden. The current study aimed to understand the impact of caregiving burden and perceived social support on psychosomatic symptoms. Three instruments, along with a demographic sheet, were utilized to collect data. SPSS software was employed for descriptive statistical computation, correlational analysis, and regression analysis. The findings from the correlational analysis indicated that caregiving burden has a significant positive correlation with psychosomatic symptoms, whereas perceived social support shows a significant negative correlation with both caregiving burden and psychosomatic symptoms. Furthermore, caregiving burden is a significant positive predictor, while perceived social support is a significant negative predictor of psychosomatic symptoms. The overall model accounted for a substantial portion of the variance in psychosomatic symptom severity. These results provide direct evidence to guide the development of targeted support interventions aimed at alleviating caregiving burden and enhancing perceived social support.
