P1‐142: Reliability of the Canadian occupational performance measure in Brazilian older adults with mild cognitive impairment
Bibliographic record
Abstract
The Canadian Occupational Performance Measure (COPM) is a scale used in occupational therapy to assess clients’ perceived performance of daily activities and their satisfaction with their performance. This scale can be used in diverse populations, including geriatric patients with dementia, mild cognitive impairment (MCI) and other neuropsychiatric disorders. This is the first study of reliability of this scale in MCI patients both in Brazil and worldwide. 55 older adults with MCI (Petersen's criteria) were assessed using the COPM. Test-retest was accessed in 27 MCI patients. An occupational therapist made the COPM interview and repeated the test 2 weeks later. The reliability of inter-rater agreement was accessed in the remaining 28 patients, which were interviewed with COPM by two different occupational therapists in the same day . Pearson's correlation test was used in the analysis. Correlation of the problems identified (ex.: climbing stairs, paying bills, etc) in the performance of daily activities in the test-retest was 0.74 (p < 0.001) and for inter-rater agreement was 0.72 (p < 0.001). For the problems identified a score was given for the level of performance. In the test-retest the correlation of this score was 0.09 (p = 0.776) and in the inter-rater evaluation it was 0.66 (p < 0.001). A score of satisfaction with the performance is also given through the COPM and in the test-retest the correlation was -0.11 (p = 0.715) and in the inter-rater it was 0.67 (p < 0.001). Results showed that the COPM has generally a good reliability both in the test-retest and in the inter-rater agreement for problems identified. Less consistent results were found to the performance perceived and level of satisfaction with the problems in the test-retest, perhaps because it depends on more subjective parameters and a longer period (2 weeks) has passed between interviews. The COPM can be used to evaluate problems in the performance of daily activities in MCI elderly patients.

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.
