Summary
This study identified three distinct dimensions of physical functioning in older adults: Mobility Activities, Daily Activities, and Social/Participation. These findings support separate Activity and Participation dimensions within the International Classification of Functioning, Disability, and Health.
Area of Science:
- Gerontology
- Rehabilitation Science
- Health Sciences
Background:
- The International Classification of Functioning, Disability, and Health (ICF) proposes distinct Activity and Participation dimensions.
- Empirical validation of these dimensions using physical functioning measures is needed.
Purpose of the Study:
- To determine if physical functioning items from the Late Life Function and Disability Instrument align with ICF's Activity and Participation dimensions.
- To test the hypothesis of distinct Activity and Participation dimensions.
Main Methods:
- Cross-sectional survey design with 150 community-dwelling adults aged 60+.
- Exploratory factor analysis of 48 physical functioning questionnaire items.
Main Results:
- A single dimension was insufficient to explain the data.
- Three distinct factors emerged: Mobility Activities (24.4%), Daily Activities (24.3%), and Social/Participation (12.4%).
- All factors demonstrated high internal consistency (alpha ≥ 0.90).
Conclusions:
- Distinct concepts within physical functioning align with ICF's Activity and Participation dimensions.
- This study provides empirical evidence for separate Activity and Participation dimensions in the ICF framework.
- The findings contribute to a better understanding of physical functioning in older adults.
