The aim of this study was to investigate the relationship between procrastination and self- concept, specifically focusing on whether individuals who exhibit higher levels of procrastination tend to have a lower self-concept. A total of 156 participants, comprising undergraduate and graduate students, completed the General Procrastination Scale and the Personal Self-Concept Scale. The findings revealed a significant inverse relationship between procrastination and self-concept, indicating that students who procrastinate more tend to report lower overall self-concept. The strongest negative correlation emerged between procrastination and self-fulfillment, suggesting that frequent procrastination is associated with diminished feelings of personal achievement and fulfillment. Furthermore, procrastination was negatively correlated with autonomy, emotional adjustment, and honesty, implying that students who procrastinate also experience reduced autonomy, emotional regulation, and integrity in self-perception. These results underscore the multifaceted impact of procrastination, suggesting it influences not only task management but also fundamental aspects of one's self-image. While the study offers valuable insights into the psychological dimensions of procrastination, its findings are limited by the sample's demographic homogeneity, pointing to the need for future studies with more varied populations.
