Summary
The Dysfunctional Behaviour Rating Instrument (DBRI) reliably measures behavioral issues in older adults with cognitive impairment. This caregiver-reported tool is valid for community-dwelling elderly.
Area of Science:
- Gerontology
- Neuropsychology
- Psychometrics
Background:
- Cognitive impairment in older adults presents challenges for caregivers.
- Accurate assessment of dysfunctional behavior is crucial for effective care planning.
Purpose of the Study:
- To evaluate the reliability and validity of the Dysfunctional Behaviour Rating Instrument (DBRI).
- To assess the DBRI's utility in community-dwelling older adults with cognitive impairment.
Main Methods:
- 184 community-dwelling older adults with suspected cognitive impairment were assessed.
- Caregivers completed the DBRI, Behaviour Problem Checklist (BPC), and Lawton Scale.
- Reliability was measured using intraclass correlation coefficients; validity was assessed via correlation coefficients.
Main Results:
- The DBRI demonstrated good reliability (intraclass correlation coefficient = 0.75).
- A strong correlation was found between the DBRI and the BPC total score (0.71).
- Correlations with specific BPC domains varied, with cognitive and activities of daily living domains showing moderate associations.
Conclusions:
- The DBRI is a specific, reliable, and valid caregiver-reported measure.
- It is suitable for assessing dysfunctional behavior in cognitively impaired elderly individuals living in the community.
