People with Alzheimer’s disease (PwAD) remain able to speak coherently about their daily life for a long time, and their level of awareness could be determined through their discourse. In a grounded-theory approach, awareness of self and awareness of disease are intertwined and can be observed through three domains: mechanisms, objects and modes of expression.
Objective:
Based on preliminary results, in this article, we present the ASDA (Awareness of Self and Disease Assessment), a new subjective measurement tool for awareness in PwAD. To consider its use in research and practice, we initially performed validation analyses, including internal consistency, test-retest reliability and interrater reliability analyses.
Methods:
The new assessment tool consists of a semi-structured interview and ratings of 22 items divided into three categories. As part of our observational study, we assessed a sample of 28 PwAD who participated in four interviews (one every two weeks).
Results:
The ASDA shows good homogeneity within the domains of awareness and a certain degree of stability between two measurement times and between investigators. Missing values in the results provided information regarding awareness levels within and across the subjects.
Conclusion:
The results suggest that awareness could be assessed through subjective experience without reference to a comparison.
