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

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
