Description:

The Dimensional Change Card Sort (DCCS) Border Version is an iPad-administered task (by a research assistant) that measures the flexible use of rules to govern behavior as a means of providing an index of executive function development. DCCS is a measure of cognitive flexibility. Two target pictures are presented that vary along two dimensions (e.g., shape and color). Participants are asked to match a series of bivalent test pictures (e.g., yellow balls and blue trucks) to the target pictures, first according to one dimension (e.g., color) and then, after a number of trials, according to the other dimension (e.g., shape). “Switch” trials are also employed, in which the participant must change the dimension being matched. For example, after four straight trials matching on shape, the participant may be asked to match on color on the next trial and then go back to shape, thus requiring the cognitive flexibility to quickly choose the correct stimulus. Scoring is based on a combination of accuracy and reaction time. The DCCS task is a simplified version of the Wisconsin Card Sorting Test (WCST) that is available on the National Institutes of Health (NIH) Toolbox, where investigators will need to pay a licensing fee. The DCCS is suitable for testing subjects between the ages of 3 and 85. This task has demonstrated superior test-retest reliability in adult populations Zelazo et al. (2014).

Summary of the Dimensional Change Card Sort (DCCS) Border Version

The DCCS Border Version makes use of two different styles of bivalent cards, displaying, for example, a red boat and blue rabbit. The test cards additionally have either no border or a black border.

The protocol consists of the research assistant preparing the administration on an iPad, where data are transmitted via the Internet to the Apple iCloud for download by the investigator.

Personnel and Training Required

The assessor should be trained to respond in a neutral, nonevaluative, noncorrective manner during the task. The assessor should be trained in how to respond to hesitant or resistant behavior by the participant.

Equipment Needs

The iPad Air or iPad Air2 with Wi-Fi capacity that is running iOS version 8.4 or later.

Requirements

Requirement CategoryRequired
Average time of greater than 15 minutes in an unaffected individualNo

Life Stage:

Child, Adolescent, Adult

Specific Instructions:

None

Definition

This measure assesses flexibility in detection and use of rules that govern behavior.

Purpose

Cognitive flexibility is one component of the multidimensional construct "executive function." This measure provides a marker of the development of executive function. Substance use has been shown to correlate with deficits in both cognitive flexibility and other aspects of executive functioning.

Selection Rationale

The Dimensional Change Card Sort (DCCS) is an easily administered and widely used measure of executive function.
