Suicidal Ideation and Behavior in Adolescents Aged 12–16 Years: A 17‐Year Follow‐Up
Bibliographic record
Abstract
The prevalence of suicidal ideation/behavior in 1983 or 1987 and its association with future mental health in 2001 were evaluated in a provincially representative sample of Canadian adolescents (n = 1,248) aged 12 to 16 years. Approximately 13.3% (95% CI = 11.5-15.3) of adolescents self-reported suicidal ideation/behavior. Adolescent agreement with parent (κ = .07) and teacher (κ = .05) reports at baseline was low because adults identified so few subjects. In adulthood, the associations between adolescent self-reports of suicidal behavior/ideation and major depression and other mental health indicators were explained by respondent sex and adolescent emotional problems reported in 1983/1987. Adolescents with suicidal behavior/ideation often are not recognized by their parents and teachers and may be at risk for persistent psychiatric problems attributable to coexisting mental health problems early-on.

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.
