Intra- and inter- rater reliability of the face-to-face assessment and tele-assessment of performance-based tests in older adults

AimTo investigate the intra- and inter-rater reliability of the face-to-face assessment and tele-assessment of performance-based tests in older adults.FindingsThe results of this study suggest that the Timed-Up and Go, Five Times Sit-to-Stand Test, and 4-Meter Walk Test (4MWT) seem to be reliable tools of tele-assessment in older adults.MessageThese practical assessment tools can be used in home settings for older adults as tele-health interventions. PurposeThis study aimed to assess Timed-Up and Go (TUG), Five Times Sit-to-Stand Test (5xSST), and 4-Meter Walk Test (4MWT) intra- and inter-rater reliability between face-to-face and tele-assessment tools in older adults.MethodsA total of 54 older adults (aged >= 65 years) were included in the study. Measurements (TUG, 5xSST, and 4MWT) were carried out face-to-face and tele-assessment. The intraclass correlation coefficients (ICCs), and Bland-Altman plots was used determine intra- and inter-rater reliability.ResultsThe mean age of the participants, 53% of whom were female, was 69.59 years. Inter-rater reliability between face-to-face and tele-assessment was as following: excellent for TUG (ICC = 0.931) and 5STS (ICC = 0.908), and good for 4MWT (ICC = 0.803). In addition, intra-rater reliability between the two tele-assessments was excellent for all tests. The ICC values for TUG, 5STS, and 4MWT were 0.973, 0.948, and 0.934, respectively.ConclusionTo conclude, the TUG, 5xSST, and 4MWT seem to be reliable tools of tele-assessment in older adults. These practical assessment tools can be used in home settings for older adults as tele-health interventions.
