This study was to examine the relationships between self-regulation, time management, academic stress, and academic procrastination. The final subjects were 448 university students in Seoul, Korea. The results showed that self-regulation, time management and academic procrastination were statistically associated with each other. Academic stress was statistically correlated with academic procrastination. Female students had higher time management, academic stress, and academic procrastination than male students did. Time management partially mediated between self-regulation and academic procrastination. As a result of multi-group analysis, gender differences were not statistically significant in the relations between self-regulation, time management, academic stress, and academic procrastination. Implications of the study were discussed in university settings.
