The California Older Adult Stroop Test (COAST) is a Stroop-type test specifically designed and normed on an older adult population. Traditional Stroop-type tests often incorporate blue as a color; older adults may have difficulties distinguishing blue from green accurately due to changes in their vision, which can interfere with accurate results. Blue-green color confusion can be particularly pronounced in persons with dementia. Our test uses red, green and yellow colors and is briefer, suiting older adults in a wide range of clinical and research settings.
The COAST is a timed test and requires use of a stopwatch.

Features of the COAST
Purpose: Use a Stroop-type test designed specifically for older adults.
Length: 50 cards
Average completion time: 15 minutes
Target population: Age 60 and over
Administration: For individual administration
Extra materials needed: Stopwatch
Comparison norms: Normative data for the COAST is provided for healthy older adults, as well as those with type-II diabetes (representing norms for older adults with a chronic medical condition), depressed outpatients, psychiatric inpatients and persons with dementia.
Uses of the COAST
The COAST allows computation of time to completion for the familiar three traditional Stroop-type tasks (Color Naming, Word Naming and Inference) with normative data for time to completion of each trial, in addition to self-corrected and total errors for each individual trial. Scoring is quick and easy.
