A novel evaluation approach for the ability of older adults based on grey clustering model

Abstract

PurposeThe purpose of this study is to advance a novel evaluation index system and evaluation approach for ability of older adults in China.Design/methodology/approachThis study constructed a comprehensive older adult ability evaluation index system with 4 primary indicators and 17 secondary indicators. Grey clustering analysis and entropy weight method are combined into a robust evaluation model for the ability of older adults.FindingsThe result demonstrates that the proposed grey clustering model is readily available to calculate the disability level of elderly individuals. The constructed index system more comprehensively considers all aspects of the disability of the elderly.Originality/valueThis study provides a quantitative method and a more reasonable index system for the determination of the disability level of the elderly.
