“…Nevertheless, we do not suggest replacing the self-reported measure of functional disability in older adults with physical performance measures. Many other factors, including cognitive status, depression, as well as other personal and environmental factors, are associated with functional disability [36–37]. However, knowing the physical performance indices of older adults on these tests could help clinicians to determine the disability risk levels to perform appropriate interventions.…”

Background Functional disability is a common health burden in older adults and follows a hierarchical pattern. Physical performance measures are useful for the objective estimation of functional disability. This study primarily aimed to compare the validity of handgrip strength and gait speed, alone and in combination, for recognizing the functional disability among Chinese older adults. This study also aimed to stratify the functional disability according to the criterion-referenced values of handgrip strength and gait speed. Methods We selected 6127 respondents from the 2011 wave of the China Health and Retirement Longitudinal Study. Here, we defined functional disability as needing any help in any items of activities of daily living (ADL) and instrumental activities of daily living (IADL). To assess the validity of physical performance measures alone and in combination for the recognition of functional disability, we conducted the receiver operating characteristic analysis. Results Compared with handgrip strength, the gait speed could better discriminate ADL disability and showed a satisfactory discriminant validity (area under the curve ≥ 0.7) in men. However, this finding was not found in the recognition of IADL disability. When combining these two measures, the parallel test showed a high sensitivity with a poor specificity, whereas the serial test showed a perfect specificity with a poor sensitivity. Conclusion We developed the hierarchical cut-off values of handgrip strength and gait speed for identifying and stratifying the functional disability among Chinese adults over 60 years old. The speed test was superior to handgrip strength in identifying ADL disability. The parallel tests of those with high sensitivity perhaps could help identify the functional disability. Further work on cost-utility analysis is warranted.

“…ADL: A total of 6 studies reported on tools assessing ADL. The Sinhala version of ADL(42) had good internal consistency with a Cronbach’s alpha of 0.92 and the ICC for all the raters were above 0.5 indicating moderate to excellent reliability. Bartlet’s test was significant and sampling was adequate with KMO=0.898.…”

There have been many geriatric tools developed to assess health status targeting especially for older adults from developed nations but not context specific. Whereas finger count tools are available for LMICs, especially the South Asia population. CGA, as opposed to medical examination, uses multiple tools to capture a holistic health status of the older adults in line with the more comprehensive WHO definition of health. It includes a harmonized evaluation of the clinical, functional, psychological, environmental and social health status of older population. Although there is no standardized format for carrying out CGA, there is broad consensus on the domains that need to be measured. For the better caring of culturally diverse South Asian older population, we need to develop more culturally competent CGHA tools. So, this review summarised studies that describe validated tools for assessing geriatric health in community settings in South Asia. We followed Arksey and O Malleys five-stage scoping review framework, refined with the Joanna Briggs Institute methodology, to identify the research questions, identify relevant studies, select studies, chart the data, and collate and summarize the data. Using the PRISMA-ScR guidelines, a search of 3 databases (PubMed, Embase and PsychInfo was undertaken. After applying eligibility criteria to 607 articles, only 46 studies met the inclusion criteria. 7 studies reported on medical assessment, 4 studies assessed psychological condition,6 studies assessed functional issue,2 studies assessed social wellbeing and 9 studies reported on different domains. None study measured all domains. 24 tools calibrated with Gold standard measure, were validated and reliable by assessed with psychometric properties such as sensitivity, specificity, PPV, NPV and ROC-AUC. Meanwhile, 21 tools were validated exclusively for older adults, whereas there are no validated tools available for CGHA in South Asia. This review will guide us for development of CGHA tools or adaptation of existing tools in our context. As well, it will help practitioners to develop tools to measure comprehensive health of the elderly in their context.

Introduction This study aimed to develop and psychometrically test the peer relationship scales (PRSs) for the Chinese community-dwelling elderly. Methods Based on the Adams–Blieszner–Ueno integrative conceptual framework, we first drafted item-pool from the literature review, in-depth interviews, and group discussion. After a cross-sectional study in Chongqing, PR, China, we recruited a random sample of 404 community-dwelling individuals aged ≥ 65 years. Subsequently, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed to examine the factor structure of the scales. Cronbach’s alpha coefficient and split-half reliability were used to assess internal consistency. Moreover, test–retest reliability, concurrent validity, and construct validity were all calculated. Results The results supported a two-factor (ie, quantity of intimate peer relationship, the quantity of non-intimate peer relationship) model for PRS-Quantity and a 12-item three-factor (ie, cognitive process, affective process, behavioral process) model for PRS-Quality. The Cronbach’s alpha was 0.870 for PRS-Quantity and 0.851 for PRS-Quality. Both scales showed good test–retest reliability (r = 0.890 for PRS-Quantity, r = 0.889 for PRS-Quality), concurrent validity (r = 0.832 for PRS-Quantity, −0.800 for PRS-Quality), and acceptable construct validity. Discussion Overall, our findings suggested that the PRSs are reliable and valid measurements to evaluate the quantity and quality of peer relationships among Chinese community-dwelling elderly. The scales may serve as attempted tools for researchers and practitioners to access the social health of the elderly and evaluate the effectiveness of related services.
