Purpose: To investigate the level of life satisfaction and burden for primary caregivers of patients with dementia in day care centers and in their homes. Method: From August to September 2003, 56 caregivers of patients with dementia in day care centers and 54 caregivers in their homes were surveyed through three questionnaires: Life Satisfaction Index-Z and Korean Dementia Caregiver Burden. Result: Life satisfaction of caregivers in day care centers was significantly higher than that of caregivers in their homes(p<.005). Also, the sense of burden of caregivers in day care centers was significantly lower than that of caregivers in their homes(p<.005). Caregivers in day care centers showed significantly lower levels in four subdimensions of burden than those of caregivers in their homes. The level of life satisfaction of caregivers in day care centers and in their homes were also negatively correlated with the sense of burden(p<.005, p<.005). Conclusion: Using day care centers for patients with dementia will be a good way to take care of them because their primary caregivers can have more rest time and less burden. Therefore, using day care centers for patients with dementia should be recommended and the number of the facility should be increased nationwide.
