Suicidal behaviour in first‐episode psychosis: The relevance of age, perceived stress and depressive symptoms
Bibliographic record
Abstract
The onset of first episode psychosis (FEP) is a period of increased risk of suicide, which is 60% higher than in other stages of the disease. This work explored suicidal behaviour and its most relevant factors in a population with FEP and a healthy control (HC) sample. We used the Suicide Risk Scale of Plutchik (SRSP) to assess suicide behaviour, and Calgary Depression Scale for Schizophrenia (CDSS), Young Mania Rating Scale (YMRS), Personal and Social Performance Scale (PSP), Perceived Stress Scale (PSS) and Positive and Negative Syndrome Scale (PANSS) were administered to assess the severity of depression, mania, psychosocial functioning, perceived stress and psychopathology, respectively. Patients with FEP showed a higher prevalence in all measures of suicide behaviour than HC. Younger age and depressive symptoms were the most important predictors of suicide ideation and suicide attempt. More perceived stress and higher hopelessness were the most relevant predictors of suicide risk. Symptoms did not appear to be important factors in suicide behaviour. Younger age, perceived stress and depressive symptoms seem to be the most important factors in suicide behaviours in FEP.

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.
