Purpose: The purpose of this study is to verify the moderating effect of family strengths on the relationship between

care time and care burden and depression among primary caregivers of disabled persons. Methods: This study is

a secondary analysis study using data from the 4th Disability and Life Dynamics Panel (2021) to confirm the

moderating effect of family strengths on the relationship between care time and care burden and depression of

primary caregivers of persons with disabilities. Results: The results of the study showed that the care burden of

primary caregivers of disabled persons increased depression, and family strengths lowered the effect. These results

suggest a policy to promote family strengths, as the care burden of primary caregivers of persons with disabilities

is a risk factor that can increase depression, and low family strengths can increase depression due to care burden.

Conclusion: Based on the results of this study, it is expected to serve as basic data for establishing the direction of

institutional improvement of welfare for disabled households in the future as a measure to alleviate and prevent

depression of primary caregivers of disabled persons.
