Evaluating the Sociocultural Risks for Suicide Attempt in Schizophrenia
Bibliographic record
Abstract
Sociocultural factors involved in immigration and ethnicity are believed to independently influence the risk for schizophrenia and suicidal behaviour. Schizophrenia patients are known to be at an increased risk for suicide. Though many risk factors have been identified, few have any significant clinical impact on predicting suicide. Whether immigration and ethnicity are potential risk factors for suicide attempt in schizophrenia has yet to be investigated. Schizophrenia patients with clear suicide attempt history, immigration history, self-reported ethnicity, and other sociocultural and clinical variables were recruited to test whether independently, or synthesized in a classification algorithm, these variables can accurately predict a history of suicide attempt. Both immigration and ethnicity had a non-significant association with suicide attempt. Inclusion of these predictor variables also did little to improve classification accuracy in our algorithms. Taken together, we found no evidence that these sociocultural factors have a significant influence on the risk for suicide attempt in schizophrenia.

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.
