A sample of 2162 students from Middle Eastern countries: Jordan (n = 470), Saudi Arabia (n = 279), United Arab Emirates (n = 315), Egypt (n = 625), Oman (n = 237), and Sudan (n = 189) (female = 1706; 78.9%; mean age = 33.36, SD = 10.69). Data were collected using the Nomophobia Questionnaire (Yildirim et al., 2016), the UCLA Psychological Loneliness Scale (Russell, 1996), the Sleep Disorders Questionnaire, and a demographic questionnaire. Overall, the level of nomophobia was moderate (M = 64.12, SD = 16.9). In addition, Saudi students scored the highest (M = 3.35), while Sudanese students scored the lowest (M = 3.07). A stepwise multiple regression analysis indicated that sleep disorders were the strongest predictor of nomophobia, followed by daily smartphone usage and participants’ age. The findings further revealed significant cross-national and demographic variations, particularly higher levels of nomophobia among Saudi and married participants. Significant differences were also observed by type of work, those who work at the public-sector showed higher nomophobia scores compared to students. Gender differences were not significant, suggesting that smartphone dependence is similar for both males and females. The results confirmed that behavioral and sleep-related factors explain nomophobia more strongly than emotional loneliness. The Findings are consistent with Work–Life Balance Theory (Clark, 2000) concerning how blurred boundaries and functional motivations reinforce nomophobia behaviors. These findings suggest the need for targeted student counselling and guidance programs that address smartphone overuse, promote healthy sleep hygiene, and support students’ psychological well-being through preventive approaches.
