Delis-Rating of Executive Function (D-REF)


Detect executive function issues based on behaviors

Delivered online via Pearson’s new Q-global scoring and reporting platform, D-REF lets you quickly and easily administer, score, and report the frequency of observed behaviors that identify executive function problems in children and adolescents ages 5-18. This flexible, sensitive assessment includes parent, teacher, and self-ratings with 36 items that are answered as: Seldom/Never; Monthly; Weekly; or Daily.

Uses & Applications

Clinicians and school psychologists working in a variety of settings can use this instrument to evaluate children with:

  • ADHD-Combined
  • ADHD-Inattentive
  • Traumatic brain injury
  • Autism/Asperger’s Syndrome
  • Neurological/psychiatric disorders
  • Learning disabilities
  • Enable the identification of patterns of clinically relevant symptoms
  • Identify symptoms that create the most stress for the parent, teacher, and child for intervention
  • Identify symptoms relevant to diagnostic criteria (DSM-IV)
  • Track changes in behavior after intervention



Content & Administration

Three core indexes and a total composite score are provided via the D-REF online scoring and reporting site that are based on three manifestations of executive control problems:

  • Behavioral functioning
  • Emotional functioning
  • Cognitive functioning
  • Total index calculated from the three core indexes

Four additional second level index scores are available to identify patterns of clinically relevant symptoms:

  • Attention/Working Memory Index
  • Activity Level/Impulse Control Index
  • Abstract Thinking/Problem Solving Index
  • Compliance/Anger Management Index

Features & Benefits

  • Online administration and scoring
  • Paper forms can be printed off when necessary and key stroked into the scoring program
  • Parent and teacher rating forms for ages 5-18; self-rating forms for ages 11-18
  • Parent and teacher forms can be sent as links to their email address or printed out if access is not available
  • Single rater reports are offered for the parent, teacher, or child, as well as multiple rater reports with comparative statistics
  • A text-to-speech function allows items to be read to the client
  • Items are written at a fourth grade reading level
  • Part II features the “Top 5 Stressors” section to prioritize behaviors for immediate intervention
  • Monitor progress over time to evaluate intervention effectiveness

Psychometric Information

  • Choose age adjusted or age and gender adjusted norms
  • The parent, teacher and self-rating forms show high internal consistency for the three primary indexes and the composite index
  • Clinical scales have moderate to high levels of internal consistency
  • Test-retest reliability are consistent over time
  • Sensitive to common developmental disorders
