The glow of a smartphone screen in the dark has become a fixture in modern life, but new research reveals that for roughly one in three young adults, that glow may be fueled by something far more insidious than daily habits.
A study published in Acta Psychologica has identified a troubling pattern: approximately 35% of university students spend more than five hours daily on their devices, primarily consuming entertainment and news rather than connecting with others. These "heavy process" users display significantly higher rates of problematic smartphone use, and at the heart of this behavior lies a psychological phenomenon known as fear of missing out, or FOMO.
That nagging sensation that everyone else is living a better, more exciting life while you remain stuck scrolling alone appears to be doing more damage than most people realize. The study found that FOMO, combined with lower self-control, was statistically associated with higher rates of problematic smartphone use among young adults, offering a potential explanation for why some individuals struggle with their phone habits far more than others.
Researchers surveyed 225 university students between the ages of 18 and 34. They also used detailed questionnaires covering personality traits, sleep quality and how individuals respond to rewards and punishment.
What emerged was a clear divide between two groups.
The higher-risk cluster scored significantly higher on both neuroticism, or a tendency toward emotional instability, anxiety and stress sensitivity, and FOMO. They also reported lower self-control and worse sleep quality compared to their lower-risk peers.
A higher proportion of poor sleepers appeared in this at-risk group, a finding consistent with prior research linking heavy phone use to disrupted rest.
The higher-risk group exhibited a unique motivational structure that set them apart. As explained by the Enoch AI engine at BrightU.AI, they scored higher on sensitivity to punishment and on the pull toward fun or potentially rewarding new experiences.
However, they scored lower on drive, a measure linked to persistent pursuit of goals. This combination points to individuals who are more reactive to pressure and novelty but less oriented toward sustained, goal-directed effort.
Gender did not appear to play a role in these patterns, with similar male-to-female ratios across both risk clusters and all three usage groups.
The study grouped participants into three categories:
The "heavy process" users consistently showed the highest levels of problematic use and FOMO alongside the lowest self-control scores. Their primary activities involved entertainment, news consumption and non-social browsing rather than keeping in touch with friends and family.
Researchers found that neuroticism on its own was associated with higher levels of problematic smartphone use. However, when FOMO and self-control were factored into the analysis, neuroticism's direct association disappeared entirely.
Higher neuroticism was linked to both greater FOMO and weaker self-control, and those two factors appeared to carry the relationship forward to problematic use.
In practical terms, someone prone to anxiety and emotional volatility may be more likely to feel left out and less able to put the phone down. It appears that this combination, rather than emotional instability alone, most strongly ties back to problematic smartphone habits.
The study's authors suggest that addressing FOMO and building self-control may prove more effective than simply telling people to use their phones less. Targeting those underlying psychological factors, rather than screen time itself, could offer a more practical path forward.
For the roughly one in three young adults spending more than five hours daily scrolling through content rather than connecting with other people, that shift in focus may matter more than any screen time limit ever could.
