Screen time and behavioural problems among preschool children: unveiling the mediating effect of sleep quality
Bibliographic record
Abstract
Screen time is now pervasive in the lives of preschool children, posing potential risks for sleep disturbances and behavioural problems. Therefore, the present study used a questionnaire to survey mothers (Mage = 35.56 years, SD = 3.62 years) of a total of 571 preschool children (Mage = 4.70 years, SD = .88 years; 44.70% boys) in seven public kindergartens to investigate the association between screen time, sleep quality, and behavioural problems. Results shown that sleep quality partially mediated the relationship between screen time and both hyperactivity attention problems and emotional symptoms. Specifically, screen time was found to increase hyperactivity attention problems and emotional symptoms by reducing sleep quality. However, it was observed that sleep quality did not act as a mediator in the relationship between screen time and peer problems. These findings hold significance in comprehending how screen time and sleep quality are related to behavioural problems in preschool children.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
