YouTube addiction and adolescent mental dealth

A single YouTube video rarely stays a single video for long, since something is almost always cued up to autoplay right after it.

Researchers have started treating that pattern seriously enough to build a dedicated measurement tool, the YouTube Addiction Scale, rather than folding YouTube into general social media research.

That platform-specific focus is also showing up in MDL 3047, the litigation alleging major platforms were built to encourage compulsive use among children and adolescents. Court filings in the litigation specifically allege that weak age verification let young users access YouTube's recommendation system and autoplay feature, both of which plaintiffs say kept viewers watching well past what they originally intended.

How researchers measure YouTube-specific addiction

A YouTube Addiction Scale was developed using a recognized model of addiction, breaking problematic use into six measurable components:

  • Salience, or how much YouTube dominates a person's thinking
  • Mood modification and tolerance, meaning needing more use to get the same effect
  • Withdrawal and relapse after attempting to cut back
  • Conflict with school, work, friends, or family

Researchers tested the scale across two samples totaling over 1,000 participants, including adolescents in both groups. Higher scores on the scale were associated with greater depression, anxiety, and stress, giving the measure real predictive value beyond just counting hours watched.

What drives repeated viewing on the platform

A 2026 study of 356 early adolescents introduced a separate measure looking at algorithm dependence, examining how much young people relied on YouTube's recommendation system to pick what to watch next. Adolescents with the lowest reliance on the algorithm got more viewing suggestions from family members than from YouTube itself.

That finding matters because it shows the recommendation system can become the primary source of content decisions for some young viewers. Separately, a 2025 qualitative study found participants described a range of emotional responses tied to their YouTube use, including:

  • Fear, anger, and insecurity
  • Anxiety connected to specific content or creators
  • Using YouTube specifically to regulate mood or boredom

Short-form video shows a stronger anxiety link

A 2026 meta-analysis of 58 studies involving nearly 97,000 participants found a positive association between short-form video use and anxiety, with YouTube Shorts among the primary platforms studied. That association grew notably stronger when researchers specifically measured problematic use rather than general viewing habits.

The same analysis found a comparable positive association between problematic short-form video use and depression. Together, these findings suggest the pattern of use matters more than simply how many videos someone watches.

Where autoplay fits into the litigation

Unsealed litigation materials include a 2018 internal YouTube presentation examining autoplay and what the document itself called tech addiction, reportedly exploring whether limiting autoplay at night could reduce sleep disruption. Plaintiffs point to that internal research as evidence the company was aware of the feature's potential effects on sleep.

Sleep disruption is relevant here because it's associated with anxiety, depression, and other mental health difficulties documented elsewhere in adolescent research. These remain legal allegations rather than proven causation for any individual case.
