Purpose: The study was done to identify factors influencing volunteer nursing student attitudes toward elderly people. Methods: Data were collected from May 21 to June 16, 2012 using a questionnaire which included Facts on Aging Quiz and Aging Semantic Differential Scaling. Data were analyzed using t-test, ANOVA, Pearson correlation coefficient, and multiple regression with SPSS/WIN 20.0. Results: The mean score for the nursing students' knowledge of elders was 12.4±2.5 out of a possible 25 and the mean for attitudes toward elders was 84.2±9.1 with a possible range of 20~140. The nursing students' attitudes toward elders showed significant negativeness as compared to attitudes toward others as receivers of voluntary activities (p=.026). Factors significantly influencing nursing students' attitudes toward elders were 'knowledge about elders', 'religion', and 'satisfaction with voluntary work' which explained 13.7% of the variance (p<.001). Conclusion: The study results indicate that interventions to improve nursing students' knowledge about elders and increase their satisfaction in voluntary activities with elders are necessary in order to cultivate positive attitudes toward elders through voluntary work.
