The Validity of the Danish Version of the Canadian Occupational Performance Measure.

PMID 32410923WHAT IT FOUND
The Danish Canadian Occupational Performance Measure scores showed no meaningful overlap with tests of health, well-being, or general occupational behavior.
This confirms it captures unique client priorities that other common assessments miss, so it cannot be replaced by generic health measures.
Key findings
01Correlations between the COPM-DK performance/satisfaction scores and the Occupational Self-Assessment, WHO-5, and EQ-5D-5L were all low or negligible.
02Occupational therapists showed only fair agreement when trying to map the 21 items of the Occupational Self-Assessment into the three areas of the COPM.
03The study concludes that the COPM provides information about client priorities that is not obtainable from the other standardized measures used.

What it does not show
The study was limited to clients in the capital region of Denmark, so results may not generalize to other areas. Different assessors administered the tests, which could introduce variability, though the study did not measure this reliability. The analysis excluded participants with any missing data, which might bias the sample.
Declared interests
The paper does not report any funding sources or conflicts of interest.
The easy way to misread this
Do not interpret the lack of correlation as a failure of the COPM. The low correlations are the intended result, proving the COPM measures something distinct from general health or well-being. It is not a substitute for those measures, nor are they a substitute for it.
