Abstract
Abstract Cognitive impairment associated with schizophrenia (CIAS) is a relevant problem and can be well assessed in different ways, as described in an EPA guidance paper (1). In routine clinical practice, the clinician usually relies on targeted questions to elicit psychopathological findings, as described in the AMDP system (2), for example. If there is a need for a more precise assessment of cognitive dysfunction, also in a transdiagnostic way, the Screen for Cognitive Impairment in Psychiatry (SCIP) (3) has recently been used by several working groups. In a recent pilot study (4), we used the German version of the SCIP (SCIP-G) (5,6) to assess cognitive impairment in acute psychiatric inpatients diagnosed with psychotic disorders, bipolar disorder and depression.

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.
