This study aims to confirm the effect of social support on career preparation behavior and the mediating effect of resilience in college students majoring in modern dance. 182 college students from the dance department of a four-year university located across the country were surveyed and the data were processed using the SPSS 18.0. Principal components, factor analysis and reliability analysis were conducted to verify the validity and reliability of the variables. After that, multiple regression analysis and mediated regression analysis were performed through variable calculation, and the results derived from the analysis are as follows. First, it was found that teacher’s support of social support had a positive effect on all sub-variables of career preparation behavior. Second, in the relationship between all variables of teacher’s support and career preparation behavior, self-regulation ability was found to have a partial mediating effect on the relationship between teacher’s support and information collection behavior. Based on the results and discussions, it is essential that the university administration establish a system for communication between teachers and students followed by the emphasis on an enhanced additional research on resilience.
