Child Psychiatric Epidemiology and Canadian Public Policy-Making: The State of the Science and the Art of the Possible
Bibliographic record
Abstract
Epidemiological studies have characterized the high burden of suffering that child psychiatric disorders cause--14% of children (1.1 million in Canada) have clinically important disorders at any given time. In this review, we summarize the recent research and discuss several unresolved scientific issues that must be addressed to make epidemiology more useful to policy-makers. We then discuss implications for policy-making to improve children's mental health outcomes. Overall, given the high prevalence rates, increasing clinical services alone will not suffice; rather, a multifaceted mix of strategies is required.

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.
