OBJECTIVE: This study examined the parallel-forms reliability of a web application (app) of the Activity Card Sort Australia for adults ages 18–64 and assessed its clinical utility.
METHOD: Forty-eight participants completed the app and card versions of the tool within a 2- to 3-wk interval and provided feedback via a purpose-designed survey. Intraclass correlation analysis tested parallel-forms reliability.
RESULTS: The app demonstrated acceptable parallel-forms reliability for overall retained activity level (r = .75, p < .001), the daily life domain (r = .77, p < .001), and the recreation and relaxation domain (r = .74, p < .001), but not for the physical activity domain (r = .59, p < .001). Clinical utility responses suggested good acceptance of both versions.
CONCLUSION: The results suggest that further studies are required before the app version can be used for research or in clinical settings.
