Test-retest reliability and minimal detectable change of the Cognitive Abilities Screening Instrument in patients with dementia.

ABSTRACT:

Background

The Cognitive Abilities Screening Instrument (CASI) is widely used to assess global cognitive function in patients with dementia. It contains nine cognitive domains, namely long-term memory, short-term memory, attention, mental manipulation, orientation, abstraction and judgment, language, visual construction, and list-generating fluency. However, test-retest reliability and minimal detectable change (MDC) of the CASI are largely unknown in patients with dementia, which limits its utility and the explanation of a score change.

Purpose

The purpose of this study was to examine test-retest reliability and calculate MDC of the CASI in patients with dementia.

Methods

Fifty-two patients with dementia completed the CASI twice with a two-week interval. The frequenc
