Use of the Cognitive Performance Test for Identifying Deficits in Hospitalized Older Adults
Bibliographic record
Abstract
Objectives. The Cognitive Performance Test (CPT) is a functional assessment for persons with dementia. The study purpose was to evaluate the reliability, discriminant, and concurrent validity of the CPT. Method. The CPT was tested against other measures of cognition (Standardized Mini Mental Status Exam (SMMSE) and Assessment of Motor and Process Skills-Process scale (AMPS-Process)). Participants were persons 65 years and older admitted to a geriatric rehabilitation unit (n = 47). Results. The CPT correlated moderately with measures of cognition (SMMSE r = 0.47, AMPS-Process r = 0.53, P < 0.01), and ADL burden of care (FIM r = 0.32, P < 0.05). Scores were not affected by age, sex, years of education, motor skills, or comorbidities. The CPT differentiated between impaired and unimpaired individuals differently from other measures. Conclusion. While CPT appears related to other measures of cognition, test interpretation requires noting the variability between CPT scores and those measures.

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.
