Purpose: The purpose of this study was to identify the impact of dementia knowledge, burden from behavioral psychological symptoms of dementia (BPSD) and empathy in the caring behavior of certified caregivers in nursing homes. Methods: The participants in this study were 203 caregivers who worked in 15 institutions. They were selected by quota sampling from 177 nursing homes in Jeollanam-do. Collected data were analyzed using descriptive statistics, t-test or ANOVA, Scheffé test, Pearson correlation coefficient, and multiple regression analysis. Results: Knowledge about dementia actually did not influence caring behavior (β=-.10, p=.197), but empathy towards elderly people (β=.23, p=.004) and the burden of BPSD (β=.16, p=.032) was found to have a positive influence on caring behaviors. Conclusion: The findings show that the factors that influence caring behaviors were empathy and the burden of BPSD and empathy was the most influential factor. Thus, there is a need to develop arbitration programs and include in the programs a caregiver curriculum directed at raising the level of empathy in caregivers. Also, continuous education to enable quick and accurate detection of BPSD and on how to handle it is crucial for caregivers in this sector.
