Abstract

Purpose: This study provides preliminary evidence for the acceptability, reliability, and validity of the new Alzheimer's Disease Knowledge Scale (ADKS), a content and psychometric update to the Alzheimer's Disease Knowledge Test.

Design and methods: Traditional scale development methods were used to generate items and evaluate their psychometric properties in a variety of subsamples.

Results: The final 30-item, true/false scale takes approximately 5-10 min to complete and covers risk factors, assessment and diagnosis, symptoms, course, life impact, caregiving, and treatment and management. Preliminary results suggest that the ADKS has adequate reliability (test-retest and internal consistency) and validity (content, predictive, concurrent, and convergent).

Implications: The ADKS is designed for use in both applied and research contexts, capable of assessing knowledge about Alzheimer's disease among laypeople, patients, caregivers, and professionals.
