0962 CONCOMITANT AND LONGITUDINAL CHILDHOOD SLEEP CHARACTERISTICS ASSOCIATED WITH EXTERNALIZING PROBLEMS DURING ADOLESCENCE
Bibliographic record
Abstract
Sleep problems have been linked to externalizing problems during adolescence. There is limited knowledge as to the temporal childhood sleep characteristics and subsequent adolescent externalizing problems. Our aims were 2-fold: 1) to examine whether sleep characteristics are concomitantly associated with externalizing problems at 15 years and 2) to investigate whether childhood sleep characteristics predicted externalizing problems at 15 years. Longitudinal data on 1441 children were collected by questionnaires and interviews from 5 months to 15 years (13 waves). At 15 years, sleep characteristics and externalizing problems were completed according to the adolescent’s opinion. Childhood sleep characteristics trajectories (nocturnal sleep duration, nocturnal awakening duration and sleep latency) were completed according to the mother’s opinion (2.5 months to 10 years). Pearson correlations, t-tests and Anovas were performed (p<.05). Concomitant associations were found for sleep need (p=0.01), total sleep time during weekdays (p<0.001), daytime drossiness (p<0.001) and trouble waking up (p<0.001) except for total sleep time during weekend (n.s). We found that children which followed the long sleep latency trajectory presents significant more externalizing problems at 15 years compared to children which followed the short/normal sleep latency trajectory (p=.02). Concomitant adolescent sleep problems (sleep need, total sleep time during weekdays, daytime drossiness and trouble waking up) are associated with externalizing problems at 15 years whereas childhood long sleep latency predicted the emergence of externalizing problems at 15 years.

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.
