Project Description

Summary:  View help for Summary Background: Physical activity (PA) is essential in mitigating frailty syndromes, and it is necessary to measure PA in older adults with frailty. Assessment of Physical Activity in Frail Older People (APAFOP) is a suitable patient-reported outcome measure (PROM) for assessing PA among older adults with frailty. This study aimed to determine the reliability and criterion validity of the Chinese version of the APAFOP (APAFOP-C). Methods: This cross-sectional validation study was designed to measure the reliability and criterion validity of the APAFOP-C with 124 frail community-residing older adults. APAFOP-C was completed twice within an interval of 7–17 days to determine intra-rater reliability. The investigator triangulation method was used to investigate inter-rater reliability, and a pedometer was used as the reference measurement to assess the criterion validity. Reliability and criterion validity of APAFOP-C were tested by the interclass correlation coefficient (ICC2,1) and Pearson correlation coefficient for normally distributed variables, and Spearman correlation coefficient and Wilcoxson signed-rank test for skewed variables. Agreement assessment was conducted using Bland-Altman plots for inter-rater reliability and criterion validity. Kendall's W test assessed absolute agreement among three raters in inter-rater reliability. The Mann-Whitney U test was used to evaluate whether any particular day was more representative of certain daily activities. Results: Total PA on any arbitrarily chosen day illustrates daily activity (Z= -0.84, p=.40). The APAFOP-C exhibited substantial to near-perfect intra-rater reliability (ICC2,1=.75–.97; Spearman ρ=.67–.89), and the total PA score demonstrated minimal detectable change (MDC) <10%. Inter-rater reliability was also substantial-to-perfect (ICC2,1=.96–.98; Spearman ρ=.88–1.00), and acceptable-to-substantial for criterion validity when compared with PA scores on pedometer readings (Pearson r=−.58; Spearman ρ=.60–.61). Limits of agreement among different raters regarding the APAFOP-C and the pedometer were narrow. Conclusion: The APAFOP-C was found to have limited but acceptable psychometric properties for measuring PA among community-dwelling older adults with frailty in China and a feasible comparative PROM for assessing PA worldwide. Practitioners can also develop individualized exercise programs or track changes in PA based on data derived from the APAFOP-C.
