Measuring changes in activity participation of older Australians: validation of the Activity Card Sort-Australia.
OBJECTIVE
This study explored the psychometric properties of the Australian version of the Activity Card Sort (ACS-Aus), a recently developed measure of activity participation for use with older adults. Concurrent, convergent construct, and discriminative construct validity were examined.


METHODS
The study included 93 Australian adults aged 60-95 years. Participants completed the ACS-Aus, as well as an existing Australian measure of activity participation (The Adelaide Activities Profile) and an Australian measure of subjective well-being (the Personal Well-being Index).


RESULTS
The ACS-Aus demonstrated moderate concurrent validity (r = 0.434), moderate convergent construct validity (r = 0.354), and strong discriminative validity (P = 0.000).


CONCLUSIONS
The World Health Organization has recently promoted participation as an important component of the healthy ageing process. This study has validated the use of the ACS-Aus in measuring participation of community-dwelling older adults in Australia.
