Overview

Systematic review reveals that intervention reduces screen time in preschoolers, suggesting effective strategies may exist.

Key Points

  • Intervention showed significant reduction in screen time, indicating potential for positive behavioral change.
  • Meta-analysis of 41 studies demonstrated a small beneficial impact (SMD = 0.26) on screen time reduction.
  • Subgroup analysis identified moderators including child age, intervention duration, and behavior target for effectiveness.
  • Findings support the development of strategies to promote healthy screen time habits in young children.
