Test–Retest Reliability and Internal Consistency of the Activity Card Sort–Australia (18-64)

Abstract

The Activity Card Sort (ACS) measures activity engagement levels. The Activity Card Sort-Australian version for adults aged 18 to 64 (ACS-Aus (18-64)) was recently developed, and psychometric properties have not yet been determined. This study was established to determine the test-retest reliability and internal consistency of the ACS-Aus (18-64) and describe activity engagement trends for healthy adults. Fifty-four adults aged 18 to 64 participated in this descriptive study. The ACS-Aus (18-64) demonstrated excellent test-retest reliability ( r = .92, p < .001) and acceptable internal consistency (α = .83). Adults aged 18 to 40 retained a lower percentage of activities than adults aged 41 to 64 for personal care, daily life, home maintenance activities ( t = -2.22, p = .03), and recreation and relaxation activities ( t = -2.38, p = .02). The ACS-Aus (18-64) may be used to explore the activity engagement patterns of community-dwelling Australian adults aged 18 to 64. Further research will determine validity for clinical populations.

Parallel-Forms Reliability and Clinical Utility of an Application Version of the Activity Card Sort Australia (18–64)

“…More participants identified as Australian/New Zealand ethnicity in this study (83.33% compared to 66.67%) and the distribution of participants across education levels was very similar. Due to a similar spread of demographics, this study appears to have the potential to demonstrate high levels of reliability as found for the card version of the ACS Aus (18-64) (Gustafsson et al, 2017).…”

“…The next step was to examine participant experiences and the clinical utility of the app version. Before discussing the results, it is important to consider how the study demographics compare to those in the ACS Aus (18-64) study conducted by Gustafsson et al (2017). The distribution of participants across age groups in this study (18-44 years = 47.9%; 45-64 years = 52%) was more equitable than the age group distribution (18-44 years = 61%; 45-64 years = 38.9%) as reported by Gustafsson et al (2017).…”

Gender was very similarly distributed; however, this RELIABILITY OF THE ACS AUS (18-64) APP 9 study had a slightly higher percentage of male participants (31.35% compared to 24.07%).…”

“…The findings of these studies can be considered collectively, as the ACS is culturally adapted by modifying the activity cards to represent the given culture while the underlying methodology remains 58 consistent (Katz, Karpin, Arit, Furman, & Hartman-Maeir, 2003). Initial psychometric testing 59 of the ACS Aus (18-64) has also been completed with 54 healthy adults aged 18-64 years, 60 indicating high test-retest reliability (ICC = 0.92, p < 0.001) and acceptable internal 61 consistency (α = 0.83) for all domains (Gustafsson, Hung, & Liddle, 2017). In a second 62 study, discriminative construct validity is supported by differences in activity engagement 63 between healthy adults (n = 16) and adults with Parkinson's disease (n = 16) (Bryant, 64 Gustafsson, Liddle, & Stillerova, 2017).…”

“…However, it is important to note that app and mobile technologies are proliferating faster than clinical evidence and the effectiveness of apps in improving health must be evaluated before use in therapeutic and clinical settings (Anthes, 2016;Carter, Liddle, Hall & Chenery, 2015). An android app version of the ACS RELIABILITY OF THE ACS AUS (18-64) APP 4 Aus (18-64) has been developed in order to promote accessibility for clients aged 18-64 years who are unable to attend occupational therapy clinics, provide a possible interface with electronic health records, and to support the use of the tool with people who have trouble holding and sorting physical cards, for example people with Parkinson's disease who have a tremor in their hands (Gustafsson et al, 2017).…”
