Purpose & Areas Assessed
One of the best ways to evaluate the health status of older adults is through functional assessment which provides objective data that may indicate future decline or improvement in health status, allowing health care professionals to intervene appropriately

(House hold instruments to assess)
Scoring Procedure
0-6 total points possible
6 points= independent
3-5 points= partially dependent
2 or less points= dependent
Psychometrics/Standardization
Although there are no formal reliability and validity reports that could be found in the literature, the tool is used extensively as a flag signaling the functional capabilities of older adults
Strengths & Weaknesses
Strengths:
Useful in creating a common language about patient function for all practitioners.
