An evaluation of the reliability and validity of the Functional Assessment Inventory
Journal of the American Geriatrics Society
|October 1, 1983
Summary
The Functional Assessment Inventory (FAI) shows satisfactory reliability and validity in VA patients. However, the stability of its social and economic scales needs further research.
Area of Science:
- Gerontology
- Rehabilitation Medicine
- Health Services Research
Background:
- The Functional Assessment Inventory (FAI) is a tool used to assess the functional status of patients.
- Evaluating the psychometric properties of assessment tools is crucial for their reliable application in clinical settings.
Purpose of the Study:
- To evaluate the reliability and validity of the Functional Assessment Inventory (FAI).
- To assess the stability of different FAI scales in a population of VA domiciliary and nursing home patients.
Main Methods:
- The study assessed interobserver, interrater, and test-retest reliability of the FAI.
- Validity was examined using the OARS instrument as a criterion.
- Assessments were conducted on VA domiciliary and nursing home patients.
Main Results:
- Interobserver and interrater reliability coefficients were generally higher than test-retest reliability coefficients.
- Validity coefficients were comparable to test-retest reliability coefficients.
- Mental health, physical health, and activities of daily living scales demonstrated good stability, while social and economic resource scales were less stable.
Conclusions:
- The Functional Assessment Inventory (FAI) demonstrates satisfactory reliability and validity for assessing VA patients.
- Further investigation is warranted into the stability of the FAI's social and economic resource scales due to observed variability.
