Abridged scale for the screening anosognosia in patients with dementia.
The objective of this cross-sectional study was to validate an abridged version of the Anosognosia Questionnaire--Dementia (AQ-D) for screening anosognosia in daily practice. The authors reduce the AQ-D from 30 items to 9, with a large sample (n = 352) of patients with Alzheimer disease (AD). The Cronbach α was .793 and an area under the receiver-operating characteristic curve was 0.946. The κ index between new abridged AQ-D (AAQ) and original AQ-D was .800. The AAQ presents good validity and reliability indicators and kept concordance with the original scale. It is quick and easy to administer and it can simplify the clinical screening of anosognosia in patients with AD.
