Sleep disturbances in youth at‐risk for serious mental illness
Bibliographic record
Abstract
AIM: To investigate sleep behaviours of youth at-risk for serious mental illness (SMI). METHODS: This study included 243 youth, ages 12 to 25:42 healthy controls, 41 asymptomatic youth at-risk for mental illness (stage 0); 53 help-seeking youth experiencing distress (stage 1a) and 107 youth with attenuated syndromes (stage 1b). The Pittsburgh Sleep Quality Index was used to assess sleep dysfunction. RESULTS: Stage 1b individuals indicated the greatest deficit in global sleep dysfunction (F = 26.18, P < .0001). Stages 1a and 1b reported significantly worse subjective sleep quality, a longer sleep latency, increased use of sleep medications as well as greater daytime dysfunction compared to the asymptomatic groups. CONCLUSION: Research investigating sleep behaviours of youth considered to be at-risk for SMI is limited. This study provides early evidence that sleep disturbances are worse for individuals considered to be at higher risk of illness development.

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.
