Delis-Kaplan Executive Function System™ (D-KEFS™) - Frequently Asked Questions

Can I use individual tests or do I have to administer the test as a whole?

I have heard some criticisms about the clinical utility of the tool as there were not many studies reported in the original manual that cited the use of the D-KEFS with different clinical groups. What is your response to this?

What client populations can I use the D-KEFS with?

 


Can I use individual tests or do I have to administer the test as a whole?

The D-KEFS has 9 stand-alone tests that can be administered on their own to assess aspects of executive function. You may select the tests that you feel are appropriate for the skills that you would like to assess.

I have heard some criticisms about the clinical utility of the tool as there were not many studies reported in the original manual that cited the use of the D-KEFS with different clinical groups. What is your response to this?

Some researchers have criticised the limited clinical data presented in the original publication manual (e.g., Schmidt, 2003). In response, Delis, Kramer, Kaplan and Holdnack (2004) pointed out that much of the test development and validity data for the D-KEFS had appeared in the mainstream neuropsychology literature rather than the test manual itself, where it was available for peer review and open to scientific critique. These points are covered in more detail in the journal article.

What client populations can I use the D-KEFS with?

The D-KEFS can be used in a wide-range of setting in which you would like to assess aspects of an individual executive function abilities. Research has looked at using the tool with people with a range of neurological conditions (e.g. epilepsy, Parkinson’s disease, multiple sclerosis), mental health difficulties (e.g. Schizophrenia), other health related difficulties (e.g. cardiac conditions, kidney disease, chronic pain) and pervasive developmental disorders (e.g. autism).
