Product Details

D-KEFS assesses the key components of executive functions believed to be mediated primarily by the frontal lobe. With nine stand-alone tests, D-KEFS allows examiners to comprehensively assess the key components of executive functions within verbal and spatial modalities. 

Benefits

  • Assess the integrity of the frontal system of the brain.
  • Determine how deficits in abstract, creative thinking may impact daily life.
  • Plan coping strategies and rehabilitation programs tailored to each patient's profile of executive-function strengths and weaknesses.
  • Choose from two forms: Standard and Alternate.
  • Generate D-KEFS score reports faster and easier with D-KEFS Scoring Assistant® software.

Features

The D-KEFS game-like format is engaging for examinees, encouraging optimal performance without providing "right/wrong" feedback that can create frustration in some children and adults.

  • Standard Record Forms, including all nine D-KEFS tests.
  • 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.

Correlates with CVLT-II

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. 21) and referenced (p. 385) In the D-KEFS Examiner’s Manual (Delis, Kaplan, & Kramer, 2001). In this study, Bohnen et al. collected data from 10 patients (in the Netherlands) who had sustained mild TBIs with post-concussive symptoms that lasted longer than 3 months (the Persistent PCS group) and compared them to mild TBI patients who had recovered from their PCS symptoms after 3 months (the Recovered group). Bohnen et al. (1992) initially demonstrated that the Persistent PCS group performed significantly worse than the Recovered Group on a modified Stroop task that incorporated a switching procedure.

Dr. Manolo Sedo of Spain recently brought to our attention a second study by Bohnen, Jolles, and Twijnstra (1992), in which patients with acute mild TBI (6 to 14 days post injury) performed significantly worse than a match control group on the modified Stroop task that incorporated a switching procedure.

We wish to thank Dr. Sedo for drawing our attention to this important study.
