تأثيرات فاعلية الذات ونقد الذات كمتغير وسيط معدل للعلاقة بين استنزاف الأنا وضبط الذات لدى عينة من طلاب الجامعة
The study aimed to determine the level of ego depletion, self-control, self-efficacy, and self-criticism among university students and verify the correlation and statistical significance level between ego depletion and each of self-control, self-efficacy and self-criticism among a sample of university students. In addition, it tests the validity of the hypothesized model for the effects of both self-efficacy and self-criticism as mediating variables modifying the relationship between ego depletion and self-control among a sample of university students. The study sample consisted of (578), including (47) male and (531) female university students. The study scales were Ego depletion scale prepared by (Salmon, Adriaanse, De Vet, Fennis, & De Ridder, 2014) and the self-control ability scale prepared by (Tangney, Baumeister, & Boone, 2004). As well as the self-criticism scale, prepared by (Gilbert, Clarke, Hempel, Miles, & Irons, 2004), and the self-efficacy scale, prepared by (Schwarzer & Jerusalem, 1995) ( All of these Scales Arabization of the current study). The study results revealed that university students feel ego- -depletion, often feel self-criticism, can control themselves, and enjoy self-efficacy. The results also showed a statistically significant relationship at the level of 0.01 between ego depletion and self-control, self-efficacy, and self-criticism among a sample of university students. The results also indicate a statistically significant relationship between self-criticism, self-control, and self-efficacy among university students at 0.01. At the same time, there was no correlation between self-efficacy and self-control among a sample of university students. It also found that ego depletion among university students positively predicts self-efficacy and can negatively predict sensitivity to self-criticism. Self-control among university students can positively predict self-criticism sensitivity. Also, self-efficacy was found to partially moderate the relationship between ego depletion and self-control, while no effect was seen on self-criticism as a moderator variable. (Published abstract)
