Montreal Cognitive Assessment Hearing Impairment (MoCA-H) in Brazilian Portuguese: criterion and construct validity
Bibliographic record
Abstract
ABSTRACT Purpose To find evidence of criterion and construct validity for the Montreal Cognitive Assessment Hearing Impairment (MoCA-H) protocol in Brazilian Portuguese. Methods The sample consisted of 70 elderly people divided into two groups: Group 1-50 subjects with hearing loss and no cognitive decline; Group 2-20 subjects with hearing loss and cognitive decline. Criterion validity was obtained by comparing Group 1 and 2 considering the overall score and the eight domains assessed in the MoCA-H. The data were analyzed using the Mann-Whitney U-test and Student's T-test, respecting the characteristics of the data collected. To verify construct validity, the correlation between the total scores of the Mini-Mental State Examination (MMSE) and the MoCA-H obtained by Group 2 was analyzed. Spearman's Correlation Test was used for this purpose. Results The analysis of criterion validity showed a difference between the groups with and without decline in naming, attention, language, abstraction, memory and delayed recall skills, as well as the MoCA-H total score, indicating significantly higher performance of Group 1. The construct validity correlation analysis was weak and non-significant (Rho=0.384; p=0.095) between the MoCA-H and MMSE scores. Conclusion The MoCA-H protocol showed good criterion validity for this specific population, making it a reliable tool for screening mild cognitive decline. However, it did not show satisfactory construct validity, indicating the need for further studies with this instrument using another protocol as a reference.

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.
