What is the D-KEFS?

What is the D-KEFS?

The Delis–Kaplan Executive Function System (D-KEFS) is a neuropsychological test used to measure a variety of verbal and nonverbal executive functions for both children and adults (ages 8–89 years).

What does the D-KEFS sorting test measure?

D-KEFS Color-Word Interference Test. This test primarily measures the ability to inhibit an overlearned verbal response (i.e., reading the printed words) to generate the conflicting response of naming the dissonant ink colors in which the words are printed.

How long does the D-KEFS take to administer?

90 minutes
It assesses fluent productivity in the verbal domain. Administration: The D-KEFS is individually administered in a game-like format. The Verbal Fluency Test is one of nine subtests which in their entirety take 90 minutes to complete. Scoring: Raw scores are converted to scaled scores (M=10, SD=3).

What does the D-KEFS color-word interference test measure?

Color-Word Interference Test (D-KEFS) This test assesses cognitive flexibility by both requiring the child to inhibit reading words denoting colors while naming the colors themselves, but subsequently asks the child to switch back and forth between naming the dissonant ink color and reading the conflicting word.

What are the Dkefs subtests?

D-KEFS Standard (Combination) Record Forms Contains the following subtests: Trail Making, Verbal Fluency, Design Fluency, Color-Word Interference, Card Sorting, Twenty Questions, Word Context, Tower, and Proverbs.

How is the Trail Making Test scored?

The TMT is scored by how long it takes to complete the test. The time includes correction of errors prompted by the examiner. If the person cannot complete the test in 5 minutes, the test is discontinued. An average score for TMT-A is 29 seconds and a deficient score is greater than 78 seconds.

What does Dkefs 20 questions measure?

The D-KEFS 20 Questions Test is a modified and standardized version of the 20 Questions game frequently used in experimental studies in neuropsy- chology to investigate abstract reasoning and concept formation skills.

How do you test for verbal fluency?

  1. The verbal fluency test (VFT) is a short screening test that evaluates cognitive function.
  2. The person is asked to list all of the animals he can think of in the next 60 seconds.
  3. To score the VFT, count up the total number of animals or words that the individual is able to produce.

What does verbal fluency assess?

Verbal fluency tasks are widely used to assess verbal functioning in clinical and research settings. This is because the tasks have compelling face validity: A person with a serious deficit in lexical access, executive control abilities or both will perform poorly in the tasks.

What does color word interference measure?

The Stroop Color and Word Test (SCWT) is a neuropsychological test extensively used to assess the ability to inhibit cognitive interference that occurs when the processing of a specific stimulus feature impedes the simultaneous processing of a second stimulus attribute, well-known as the Stroop Effect.

What does the Stroop effect tell us?

The Stroop test can be used to measure a person’s selective attention capacity and skills, processing speed, and alongside other tests to evaluate overall executive processing abilities.

What does trail making A and B measure?

Abstract. The Trail Making Test – Part B (TMT-B) is a commonly used executive control measure with a known floor effect, limiting the ability to distinguish impairment among individuals unable to complete this task in the standard time limit.

What alternate record forms are available for the D-KEFS?

Alternate Record Forms, including alternate versions of D-KEFS Sorting, Verbal Fluency, and 20 Questions tests. Alternate set of Sorting Cards available. Subtests can be recorded and scored as a complete battery or as individual subtests.

What is a subtest for D-KEFS?

Subtests can be recorded and scored as a complete battery or as individual subtests. D-KEFS is correlated with the CVLT-II, providing information concerning the role of memory on D-KEFS performance. An important study by Bohnen, Twijnstra, and Jolles (1992) was noted (p.

What are the system requirements for the D-KEFS scoring assistant ®?

The D-KEFS Scoring Assistant ® makes generating D-KEFS score reports faster and easier. Internet Explorer 8.0 or higher: An additional 65 MB of disk space will be needed to complete the installation. Use of installation discs is not recommended.
