Assessing intrinsic capacity in older adults: A concept analysis
Ilana Logvinov1, Donna Felber Neff1
1University of Central Florida, Orlando, FL, USA.
Objective:
The paper analyzes the concept of intrinsic capacity (IC) and develops an operational definition for nursing practice.
Design:
Walker and Avant's1 eight-step guideline was applied for the concept evaluation.
Data Sources:
A thorough search of CINAHL, MEDLINE, PubMed, Abstracts in Social Gerontology, and APA PsychInfo yielded 25 original research publications from nursing, gerontology, and nutrition (2008 - 2024).
Results:
IC antecedents include personal characteristics, family history, and genetic predisposition, while changes in IC may lead to frailty and negative health outcomes. Defining attributes identified are: (a) dynamic concept and changing throughout life, (b) multidimensional consisting of vitality, locomotion, cognition, psychological, and sensory domains, (c) physical capacities, (d) mental capacities, (e) natural or acquired internal capacities. Rogers's2 client-centered theory supported the findings.
Conclusion:
An operational definition of IC is pivotal for predicting health outcomes in older adults, emphasizing the need for continuous monitoring of IC across interconnected domains.
