Updating and validating the Domestic and Community Skills Assessment.
Neil Woodroffe, Kate E Webster, Siann Bowman
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
1Content validity was established: all items scored a CVR of 0.78 or higher, and the overall CVI was 0.98.
2The assessment was reduced from 17 to 14 subtests and the Supporting Interview was removed, shortening administration time but eliminating the screening tool.
3Only 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.
