Updating and validating the Domestic and Community Skills Assessment.
Neil Woodroffe, Kate E Webster, Siann Bowman
PMID 42304555WHAT IT FOUND
The DACSA-3, a revised IADL assessment for mental health clients, has been reviewed by experts who confirmed it covers the right tasks.
But it has not been tested for reliability or whether scores actually reflect real-world performance, so treat it as a non-standardised tool.
Key findings
01Content validity was established: all items scored a CVR of 0.78 or higher, and the overall CVI was 0.98.
02The assessment was reduced from 17 to 14 subtests and the Supporting Interview was removed, shortening administration time but eliminating the screening tool.
03Only content validity has been established; construct validity and internal consistency have not yet been tested.

What it does not show
Only content validity has been established. Construct validity, internal consistency, inter-rater reliability, test-retest reliability, and normative data have all not yet been tested. The first author was also the revision author and had used the DACSA-R for over 10 years, creating a potential investment in the outcome. Some content experts were known to the revision author through their workplace, raising the possibility of social desirability bias in their ratings. Only two professionals with lived mental health experience reviewed the language, and no Aboriginal and Torres Strait Islander or multicultural consultation occurred. The content validity process was lengthy, and the authors acknowledge experts may have agreed items were essential due to fatigue.
Declared interests
Funded by La Trobe University and the Australian Government. The authors report no conflict of interest. The first author was the revision author of the DACSA-3 and had used the predecessor version for over 10 years in clinical practice.
The easy way to misread this
Do not read the established content validity as meaning the DACSA-3 is a validated, reliable assessment tool. The authors state plainly that construct validity, internal consistency, and normative data have not yet been tested, and they recommend against calculating total scores. It is a structured, expert-reviewed checklist, not a psychometrically validated instrument.
