Associations between screen time and lower psychological well-being among children and adolescents: Evidence from a population-based study

• More hours of screen time are associated with lower well-being in ages 2 to 17.

• High users show less curiosity, self-control, and emotional stability.

• Twice as many high (vs. low) users of screens had an anxiety or depression diagnosis.

• Non-users and low users did not differ in well-being.

• Associations with well-being were larger for adolescents than for children.
