Overview

The D-KEFS enables you to assess the key components of executive functions believed to be mediated primarily by the frontal lobe.

Use D-KEFS to:

  • Assess the integrity of the frontal system of the brain
  • Determine how deficits in abstract, creative thinking may impact daily life
  • Design coping strategies and rehabilitation programs tailored to each patient's profile of executive function strengths and weaknesses

Its game-like format is engaging for examinees, encouraging optimal performance without providing “right/wrong” feedback that can create frustration.

The nine stand-alone tests in the D-KEFS comprehensively assess the key components of executive function believed to be mediated primarily by the frontal lobe.

The D-KEFS tests are listed below, along with the key executive function they assess:

  • Sorting Test: problem solving, verbal and spatial concept formation, flexibility of thinking

  • Trail Making Test: flexibility of thinking on a visual motor task

  • Verbal Fluency Test: fluent productivity in the verbal domain

  • Design Fluency Test: fluent productivity in the spatial domain

  • Colour-word Interference Test: verbal inhibition

  • Tower Test: planning and reasoning, impulsivity

  • 20 Question Test: hypothesis testing, verbal and spatial abstract thinking

  • Word Context Test: deductive reasoning

  • Proverb Test: metaphorical thinking and comprehending abstract thought

Multiple uses

D-KEFS results can be used to assess the integrity of the frontal system of the brain to determine how deficits in abstract, creative thinking may impact on an individual's daily life, and to plan coping strategies and rehabilitation programs tailored to each patient's profile of executive function strengths and weaknesses.
