Hypothesis
Can proxies accurately complete the Physical Resilience Scale for older adults living with dementia?
Conclusion
The Physical Resilience Scale is reliable and valid when completed by proxy reports for older adults living with dementia.
Supporting Evidence
- The study included the first 240 patients living with dementia.
- There was evidence of reliability based on person and item separation index.
- No evidence of Differential Item Functioning between genders.
- Validity was supported based on items fitting the model except for one item.
- Controlling for age, gender, race, and comorbidities showed a significant relationship between resilience and function.
Takeaway
This study shows that family members can help answer questions about older adults with dementia's resilience, making it easier to understand their needs.
Methodology

Potential Biases
There was evidence of Differential Item Functioning by race.
Limitations
Item 10 of the scale was found to be redundant and should be removed.
Participant Demographics
