Validation of the cognitive performance scale of the <scp>interRAI‐PAC</scp> and montreal cognitive assessment
Bibliographic record
Abstract
Abstract Aims The Cognitive Performance Scale (CPS), a minimum data set instrument of the interRAI, was initially designed to evaluate cognition in residential care and has demonstrated strong diagnostic accuracy. In this study, we evaluated the diagnostic accuracy and validity of the CPS in the post‐acute care setting among post‐stroke patients hospitalized in rehabilitation wards. Design Mixed methods. Methods The observational study was conducted in rehabilitation wards. Diagnostic accuracy was used to explore the level of agreement between CPS and Montreal Cognitive Assessment (MoCA) in 321 inpatients (62.12 years; 68.2% male). Results The diagnostic accuracy of the CPS was poor when MoCA was less than 24 as a gold standard, with an area under the curve of 0.69 (standard error 0.03, 95% confidence interval = 0.62–0.75). The CPS had a poor to moderate correlation with MoCA ( r s = −.35).

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
