This study aimed to investigate the relationship between problematic social media use (PSMU), executive functions, depression, anxiety, stress, and sleep quality in a healthy adult population. A total of 174 adults (62.6% female, mean age = 37.19 +/- 9.17 years) were recruited online. Participants completed a sociodemographic data form, the Bergen Social Media Addiction Scale (BSMAS), the Executive Function Index (EFI), the Depression Anxiety Stress Scale-21 (DASS-21), and the subjective sleep quality subscale of the Pittsburgh Sleep Quality Index (PSQI). Pearson correlations were conducted. Problematic social media use showed negative associations with executive functioning, particularly with organization ( r = -.423, p < .001). In addition, BSMAS scores were positively correlated with depression ( r = .354, p < .001), anxiety ( r = .217, p < .001), and stress ( r = .233, p < .001). The findings indicate that PSMU is strongly linked to executive function and psychological distress. These results highlight the need for interventions targeting cognitive regulation, emotional well-being, and healthy technology use.
