Testing Bidirectional Associations Between Screen Time and Inattention/Hyperactivity Symptoms From Childhood to...

Area of Science:

• Child and Adolescent Psychiatry
• Developmental Psychology
• Behavioral Science

Background:

• Screen time exposure is a growing concern for child development.
• Previous research suggests a link between screen time and inattention/hyperactivity symptoms.
• Longitudinal studies distinguishing within-person from between-person associations are limited.

Purpose of the Study:

• To investigate the longitudinal associations between screen time and inattention/hyperactivity symptoms.
• To differentiate between within-person and between-person effects of screen time on behavioral symptoms.
• To examine these associations over a significant developmental period from childhood to early adulthood.

Main Methods:

• Utilized data from the Brazilian High-Risk Cohort for Mental Health Conditions (n=2,511).
• Employed random intercept cross-lagged panel models to analyze longitudinal associations.
• Assessed daily screen time via parental report and inattention/hyperactivity symptoms using the Strengths and Difficulties Questionnaire (SDQ).
• Conducted sensitivity analyses using the Child Behavior Checklist (CBCL) and Adult Behavior Checklist (ABCL).

Main Results:

• No within-person longitudinal association was found between screen time and inattention/hyperactivity symptoms.
• Initial between-person associations in the SDQ were not significant after covariate adjustment.
• Parental psychiatric history was associated with higher average screen time and inattention/hyperactivity symptoms.
• Findings were consistent across primary and sensitivity analyses (SDQ, CBCL-ABCL).

Conclusions:

• Increasing screen time beyond an individual's average does not predict future inattention/hyperactivity symptoms.
• Between-person associations between screen time and these symptoms are not robust after controlling for covariates.
• Parental factors, rather than screen time, may be more influential in the development of inattention/hyperactivity symptoms.
