PMID 33815020WHAT IT FOUND
The traditional Chinese Occupational Self-Assessment scored consistently across four areas for 593 clients with mental illness, but the environment domain did not fit as a separate domain.
OTs can use self-performance, habituation and volition scores to understand client-reported strengths.
Key findings
01The overall questionnaire and each domain showed good internal consistency, with Cronbach's alpha values of 0.934, 0.853, 0.823, 0.856, and 0.811.
02Confirmatory factor analysis supported the self-performance, self-habituation and self-volition domains, but the environment domain did not fit.
03Rasch analysis supported the four domains and their item and person separation.

What it does not show
The environment domain did not fit the expected model in confirmatory factor analysis. The diagnostic group was limited, and diagnosis was missing for 67 participants. The study did not assess cognitive competence, so it did not screen for people who might struggle with a self-report questionnaire. There was no test-retest reliability, criterion-related validity, or minimally detectable change, so score stability and meaningful change are unknown. The sample came from a university-affiliated hospital, and the authors say a more diverse capability sample is needed.

The easy way to misread this
Do not conclude that the traditional Chinese Occupational Self-Assessment is fully supported for all four domains. The environment domain did not fit the expected model, so its score should not be treated as a separate domain yet.
