Assessment of Basic Knowledge About Alzheimer's Disease Among Older Rural Residents: A Pilot Test of a New Measure
AbstractBackground and Purpose:
Underserved rural populations face a higher risk of Alzheimer's disease (AD), yet studies investigating AD knowledge in this population are lacking. The purpose of this research was to develop an AD basic knowledge measure that is appropriate for use with underserved populations.Method:
A content domain map, content validity index, and cognitive interviews were used in developing the first version of the basic knowledge of Alzheimer's disease (BKAD; Study 1). Reliability and validity of the measure in this descriptive study were examined using Rasch modeling and tests for construct, concurrent, and discriminate validity (Study 2). Multiple regression was employed to examine AD knowledge predictors.Results:
Findings included that the BKAD instrument discriminated well between persons with varied education levels. Psychometric analysis yielded important information to guide revision of the BKAD measure.Conclusion:
The BKAD measure shows promise in meeting the need for a culturally relevant measure to assess basic Alzheimer's disease knowledge in underserved rural populations.
