Screen Time and Standardized Academic Achievement Tests in Elementary School

Area of Science:

• Pediatric primary care research
• Childhood development studies
• Educational psychology

Background:

• Limited research exists on the long-term effects of various screen time types on children's academic success.
• Understanding these associations is crucial for developing targeted interventions.

Purpose of the Study:

• To investigate the longitudinal relationship between different forms of screen time in early childhood and academic performance in elementary school.
• To assess associations with standardized test results in grades 3 and 6.

Main Methods:

• A prospective cohort study involving 3322 third graders and 2084 sixth graders from the TARGet Kids! cohort in Ontario, Canada.
• Parent-reported screen time data (total, TV/digital media, video games) were linked to provincial standardized achievement test scores in reading, writing, and math.
• Adjusted proportional odds models were used to analyze the associations.

Main Results:

• Each additional hour of total screen time was associated with 9-10% lower odds of achieving higher academic levels in grade 3 reading and math, and grade 6 math.
• Higher TV and digital media use correlated with lower achievement in grade 3 reading/math and grade 6 math.
• Video game use was linked to lower grade 3 reading achievement, particularly among female students.

Conclusions:

• Elevated total screen time and TV/digital media consumption in young children are associated with diminished academic achievement in elementary school.
• Findings suggest a need for early interventions aimed at reducing screen time to foster better academic outcomes.
