Normative Data for the Dementia Rating Scale-2 in the French-Quebec Population
Bibliographic record
Abstract
The Dementia Rating Scale-2 is used to measure cognitive status of adults with cognitive impairment, especially of the degenerative type, by assessing five cognitive functions, namely attention, initiation/perseveration, construction, conceptualization, and memory. The present study aimed to establish normative data for this test in the elderly French-Quebec population. A total of 432 French-speaking elders from the province of Quebec (Canada), aged 50 to 85 years, were administered the Dementia Rating Scale-2. Age and education were found to be associated with the total score on the test, while gender was not. Percentile ranks were then calculated for age- and education-stratified groups. Previous studies have shown that cultural background can affect performance on the DRS and the development of culture-specific norms for French-speaking Quebecers could be very useful to clinicians and researchers working with this population.

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.
