Screen Time Isn't One Thing — a Study on Adolescent Risk Profiles

158 teens, three distinct risk patterns — screen time was never one problem.

DarkBadge Editorial · Jul 30, 2026

A clustering study of 158 adolescents in psychiatric care found three distinct digital-use risk profiles — not one uniform "too much screen time" pattern.

Two adolescents can log the same number of hours on their phones and be at entirely different risk. That's the finding from a Koç University study led by Dr. Zeynep Seda Albayrak: researchers ran a clustering algorithm across 158 adolescents (ages 9–18) already in psychiatric outpatient care, and found their digital use split into three distinct profiles — not one continuum of "more screen time, more problems."

Three profiles, not one number

The study grouped adolescents by psychiatric symptoms, emotion-recognition ability, and problematic digital use, and found three clusters:

  • Older girls, moderate risk — some psychiatric symptoms present, but "relatively balanced patterns of digital engagement." Symptoms alone didn't predict overuse.
  • Predominantly female, high internalizing symptoms — the largest group. Elevated anxiety and depression, strong emotion-recognition skills, lower parental education, and the highest levels of problematic social media, smartphone, and internet use of the three groups.
  • Younger boys, externalizing features — higher ADHD prevalence, weaker emotion-recognition skills, and gaming occupying a more prominent place in their digital activity than social media or smartphone use.

Why this matters for DarkBadge

DarkBadge scores design mechanisms, not hours logged — and this study is a direct data point for why that distinction matters. The highest-risk group here wasn't the one spending the most raw time online; it was the group whose psychiatric profile (anxiety, depression) intersected with products built around open-ended self-regulation failure. The gaming-heavy group's risk ran through a different mechanism entirely — ADHD and weaker emotion recognition pairing with gaming's faster reward loops, not social media's status anxiety.

The researchers' own framing: two adolescents can spend similar amounts of time online "while using technology for very different reasons." A single screen-time number can't tell you which adolescent is at risk, or why — but naming the mechanism, the way DarkBadge's dimensions try to, can.
