0902 THE INTERPLAY BETWEEN MOOD AND COGNITION IN ADOLESCENTS’ INSOMNIA
Bibliographic record
Abstract
Numerous studies have indicated that insomnia is a risk factor for internalizing problems. However, there is little understanding of the mechanisms underlying this association in adolescents. Cognitive models view internalizing problems as resulting from an interaction between cognitive distortions that predispose individuals to a higher likelihood of psychopathology, and negative mood. Experimental laboratory-based studies and clinical observations have found that sleep deprivation results in cognitive distortions and in increased negative mood. In adolescents, lower subjective sleep quality and quantity are cross-sectionally associated with negative mood, and longitudinally with increased risk of mood problems. In addition, experimentally restricting sleep in adolescents worsened mood. However, few studies have explored the interplay between negative mood, cognitive bias, and insomnia as they relate to internalizing symptoms in adolescents. The objective of this study was to examine the hypothesis that insomnia moderates the associations between affective and cognitive mechanisms that underlie internalizing problems. Thirty five adolescents (mean age 14.9 + 1.5 years) participated in the study. Negative mood and cognitive errors were assessed using self-report measures validated for youth. Insomnia was assessed using the Pittsburgh Sleep Quality Index Scale. Internalizing problems were assessed using the Child Behavior Checklist (CBCL). Regression analysis was used to examine the moderating role of insomnia status on the associations between negative mood and cognitive errors. CBCL internalizing score served as the independent variable; effects of gender and chronotype were controlled for, as these variables are known to impact internalizing problems. Analyses revealed an interaction effect of insomnia status by negative mood such that, for youth with insomnia but not for youth without insomnia, negative mood was associated with higher internalizing scores. No interaction effect was found for cognitive errors. Negative affect was associated with high levels of internalizing symptoms in adolescents with insomnia but not in adolescents without insomnia. This supports the hypothesis that disrupted sleep moderates the association between mood and internalizing problems in adolescents. Understanding how sleep, cognition and mood interact in adolescents with internalizing problems is important as it may contribute to the development therapeutic strategies that target this interaction.

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.
