STAD consists of three sections; a verbal test, an articulation test, and a non-verbal test. Each test aims to easily perform the assessment of aphasia, dysarthria, and cognitive impairment.
The following analysis support psychometric property of the STAD.
average 9 minutes 48 seconds (4–15 minutes)
internal consistency (Cronbach’s α)
verbal test: 0.90, articulation test: 0.78, non-verbal test: 0.68
1.5 SD （from 222 healthy controls aged over 50 years）
＊ In the case of a lower score than the above, some abnormality is suspected.
a toothbrush, a medical thermometer, test sheets
Heading towards the standardization of the English version of STAD, we will report at conferences and publish research articles. We will also sequentially upload the processes to the above-mentioned website. Please check it continually.
