The impact of physical activity on externalizing behaviours in children with developmental coordination disorder
Bibliographic record
Abstract
Background: Children with Developmental Coordination Disorder (DCD) often experience difficulties with motor coordination and externalizing behaviours (EB) such as rule breaking, aggression and attention problems. Literature has shown a positive impact of physical activity (PA) on internalizing problems, such as anxiety and depression, in children. However, a gap still remains regarding the effect of PA on EB. Purpose: To investigate whether PA mediates and/or moderates the relationship between DCD and EB in young children. Methods: Participants (N=589, 338 boys, Mage= 4.9±0.6 years) were part of a longitudinal cohort study, the Coordination and Activity Tracking in Children study. Motor coordination was assessed using the Movement Assessment Battery for Children – 2nd Edition. EB and ODD were measured using the Child Behaviour Checklist. Regression analyses were conducted for symptoms of ODD and EB separately. Mediating and/or moderating effects of PA on the relationship between DCD and ODD/EB were conducted using the PROCESS macro in SPSS v24. Results: Children with DCD had higher levels of ODD (b= -0.77, p

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.
