Association of Psychache and Alexithymia With Suicide in Patients With Schizophrenia
Bibliographic record
Abstract
Suicide is a leading cause of death in patients with schizophrenia. Previous studies have mostly investigated the association between suicide and sociodemographics, positive and negative symptoms, and depressive symptoms. This study evaluated psychache and alexithymia in patients with schizophrenia, which have both been associated with suicide attempts and thoughts in patients with other psychiatric disorders. Positive and Negative Syndrome Scale (PANSS), Psychache Scale (PAS), Beck Scale for Suicidal Ideation (BSSI), Calgary Depression Scale for Schizophrenia (CDSS), and Toronto Alexithymia Scale (TAS) scores were obtained in 113 patients with schizophrenia, including 50 with suicide attempts. PANSS positive symptoms and general psychopathology subscale, CDSS, BSSI, TAS, and PAS scores were significantly higher in patients with suicide attempts. In multivariate logistic regression analysis, only the PAS score was an independent predictor of attempted suicide. Mediation analysis demonstrated that psychache (both directly and indirectly) and alexithymia (indirectly) might be associated with the risk of suicide in these patients.

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.
