الثالوث المظلم في الشخصية وعلاقته بخداع الذات والميل إلى الانتحار لدى طلبة الجامعة
The study aimed to uncover the relationship between the dark triad in personality, self-deception, and the tendency to commit suicide among university students. The study was conducted on a sample of (258) male and female students at the College of Education - Mansoura University, on whom the Dark Triad scale in personality was applied (Arabization and legalization: Karim, 2016), the Self-Deception Scale (the current researcher's preparation) and the Suicide Propensity Scale (the current researcher's preparation), and by using the Pearson Correlation Coefficient, binary variance analysis, and T test, the study reached the following results: 1) There is a positive, statistically significant correlation between the students' scores on the Dark Triad personality scale, their scores on the self-deception scales, and the tendency to commit suicide. 2) There is a positive, statistically significant correlation between the students' scores on the self-deception scale, and their scores on the suicidal tendency scale. Students' suicidal tendency can be predicted by their scores on two scales: the dark triad of personality, and self-deception. There are no statistically significant differences between the average scores of students on the scales: the dark triad of personality, self-deception, and the tendency to commit suicide according to gender, academic specialization, and the interaction between them.
