Samenvatting

The Activity Card Sort (ACS) is a tool that measures activity engagement levels. In Australia, there is a recently developed adult version, named ACS-Aus (18-64). The test re-test reliability was tested in a previous study amongst individuals with a disability, but it has not yet been tested with individuals without a disability. Additionally, there has been developed an app-based version for the ACS-Aus (18-64). Purpose: The aim of this study was to test re-test the reliability of the ACS-Aus (18-64) using the original card version and the app-based version. Method: A parallel form reliability study was conducted to test re-test the ACS-Aus (18-64). The original card version was used and also a recently developed app-based version. Thirty-three healthy adults aged 18-64 participated in this research, completing two sessions with two weeks in between measurements. Each participant completed each version once and gave feedback about their experience.
