The digital citizenship skills support the seventeen Sustainable Development Goals when invested appropriately. The current research aims to determine the level of digital citizenship skills among students of Prince Sattam bin Abdulaziz University (PSAU). Additionally, it seeks to identify gender differences in the level of digital citizenship skills, unveil the relationship between digital citizenship skills and attitudes towards sustainable development, and explore the predictability of attitudes towards sustainable development based on digital citizenship skills. A total of 422 male and female students participated in the research, including 239 males and 183 females from PSAU University. The researchers employed the Digital Citizenship Skills Scale and the Sustainable Development Attitudes Scale. The study utilized a descriptive-analytical approach, specifically employing the correlational predictive method to shed light on the relationship patterns between the research variables and predict the relationships among them. The research results revealed a high level of digital citizenship skills within the research sample. There were statistically significant differences between males and females in favor of females in the level of digital citizenship skills. The findings also indicated a positive statistically significant correlation between digital citizenship skills and attitudes towards sustainable development. Furthermore, the results demonstrated the possibility of predicting attitudes toward sustainable development based on digital citizenship skills within the research sample.
