The purpose of this study is to investigate the factors that affect the social distance between the demented elderly and nursing college students. In this study, responses from 158 nursing college students in city D were collected using structured questionnaires and analyzed. As a result, the correlation between variables, social distance, and dementia attitude towards the demented elderly (r = .53, p <.001) showed a statistically correlated relationship, while ageism (r = -. 41, p <.001) showed a negative correlation. The results of this study are as follows: first, the interactions between the elderly with dementia and the nursing college students were more frequent (β = .29 p =.012), and second, attention to early prevention of dementia (β = .32 p =.002) was significant. The explanatory power of these influential factors on the social distance toward the demented elderly was 41.0%.
