Frailty: constructing a common meaning, definition, and conceptual framework
Summary
Frailty is defined as a reduced ability to perform daily activities, impacting practical and social functioning. This paper clarifies its components, contributing factors, and relation to other concepts.
Area of Science:
- Gerontology
- Public Health
- Sociology
Background:
- The concept of frailty lacks a universally agreed-upon definition, leading to varied interpretations in both common and academic discourse.
- Existing literature shows limited conceptual exploration into the fundamental nature of frailty and its influencing factors.
- This ambiguity hinders consistent research and clinical application of frailty assessment and interventions.
Purpose of the Study:
- To establish a clear and operational definition of frailty.
- To present a comprehensive conceptualization of frailty, including its core components.
- To identify and categorize factors contributing to frailty and delineate its relationship with related concepts.
Main Methods:
- Conceptual analysis of existing literature on frailty.
- Development of a novel definition based on functional capacity.
- Framework construction for frailty components, contributing factors, and related constructs.
Main Results:
- Frailty is defined as a diminished capacity to perform essential practical and social activities of daily living.
- A conceptual framework is proposed, outlining the basic components of frailty.
- Categories of factors influencing frailty and its connections to similar concepts are specified.
Conclusions:
- The proposed definition and conceptualization provide a clearer understanding of frailty.
- This work facilitates more consistent research and clinical approaches to frailty.
- Further investigation into the identified components and contributing factors is warranted.
