A New Standard in Dementia Knowledge Measurement: Comparative Validation of the Dementia Knowledge Assessment Scale and the Alzheimer's Disease Knowledge Scale.

Objectives: To compare the psychometric performance of the Dementia Knowledge Assessment Scale (DKAS) and the Alzheimer's Disease Knowledge Scale (ADKS) when administered to a large international cohort before and after online dementia education.

Design: Comparative psychometric analysis with pre- and posteducation scale responses.

Setting: The setting for this research encompassed 7,909 individuals from 124 countries who completed the 9-week Understanding Dementia Massive Open Online Course (MOOC).

Dementia Knowledge Assessment Scale: Development and Preliminary Psychometric Properties.

Objectives: To develop a reliable and valid dementia knowledge scale to address limitations of existing measures, support knowledge evaluation in diverse populations, and inform educational intervention development.

Design: A five-stage, systematic scale development process was employed to construct and assess the psychometric properties of the Dementia Knowledge Assessment Scale (DKAS).

Setting: Data for the study were generated in an online environment and during clinical dementia care placements from Australian (n = 1,321) and international respondents (n = 446).
