Use a stroop-type test designed specifically for older adults

Nancy Pachana, Bernice Marcopulos, Ruth Yoash Gantz & Larry Thompson

Manual License to Use

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 appropriate for individuals aged 60 and over. It requires a stopwatch, as it is a timed test. The COAST can normally be completed in about fifteen minutes.

The California Older Adult Stroop Test can be used:

• in assessment of older adults with a question of dementia
• in evaluating older adults with head injury or other medical, psychiatric or neurological conditions which may be interfering with cognitive functioning
• in older individuals with depression
• as a research instrument to investigate executive functioning in older populations

The California Older Adult Stroop Test (COAST) Scores
Color Naming, Word Naming, Interference Trial Scores	The COAST allows computation of time to completion for the familiar three traditional Stroop-type tasks (Color Naming, Word Naming and Interference) 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.

California Older Adult Stroop Test (COAST) Normative Samples

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.

From the COAST Manual

"In response to these highlighted problems regarding appropriateness of neuropsychological tests for older populations, a revision of the Stroop task for use with older adult populations was created and named the California Older Adult Stroop Test (COAST). The revised version is designed to minimise errors due to decreased visual acuity or color naming difficulty secondary to confusion or cataracts. Unlike traditional Stroop versions, the COAST uses only three colors that are more easily distinguished (red, yellow, and green). Alterations to the size of the printed material and the overall length of the task were also made such that only 50 items are present as opposed to the traditional 100, thereby minimizing fatigue. The new task is designed to be of utility in a broad spectrum of older clinical patients across both inpatient and outpatient settings."
