The study aims to identify the reality of cognitive distortions and self-control among Omani university students, in addition to it seeks to identify the differences in cognitive distortions depending on the university, the cumulative average, and to find modeling the impact of self control and its dimensions on cognitive distortions. The study sample consisted of (1188) male and female university students in the Sultanate of Oman, during the academic year 2021/2022, and the sample was chosen by a simple random method. To achieve the objectives of the study, the questionnaire was used as a tool for data collection, and the descriptive approach was adopted. The results of the study concluded that cognitive distortions among university students are at a high level. Accordingly, the arbitrary conclusion came in the first place for cognitive distortions, then selective abstraction, then all or nothing, then reducing the positives, then amplification and exaggeration, then personalization, then unfair comparisons, and in the last place came the excessive generalization. As for the students' self-control level, it was medium. The results also showed that there were statistically significant differences at (0.05) in cognitive distortions among students according to the university variable (military, private, government sector), in terms of arbitrary conclusion, excessive generalization, personalization, and reducing the positives, and these differences were in favor of the National University students. of science and technology versus their peers from the Military Technical College and Sultan Qaboos University. As for the cumulative average variable, these differences were statistically significant at (0.05) in terms of the ability to self-control, and its dimensions of general discipline, careful work and work ethic, in favor of students with a low average compared to students with a high average. The results of the structural equation modeling test also revealed a good fit of the model with the field data. Therefore, the value of the standard regression weight was beta (ß=-0.72), and this indicates that there is a strong influence in the negative direction and is statistically significant at the level (0.01>p) of self-control in cognitive distortions. The value of the standard regression weight beta (ß) for the five dimensions came to indicate a statistically significant negative effect at the level (0.01>p), for each of the following dimensions: general discipline, careful work, and the dimension of healthy habits (ß=-0.34, -0.39, - 0.45) in cognitive distortions; While there is no statistically significant effect of the work ethic and credibility dimensions on the cognitive distortions of university students. Finally, the study recommends the importance of holding workshops to enhance self-control skills, and to provide students with skills to deal with cognitive distortions, in addition to raising university students' awareness of the importance of discovering and diagnosing cognitive distortions of thinking, by holding training workshops and spreading awareness in social media.
