Delivered both online and in paper version, the Delis Rating of Executive Functions (D-REF™) lets you quickly and easily administer, score, and report the frequency of observed behaviours that identify executive function problems in children and adolescents ages 5 to 18 years. This flexible, sensitive assessment includes parent, teacher, and self-ratings with PART A: 36 items that are answered as: Seldom/Never; Monthly; Weekly; or Daily and PART B: rank-order the top 5 Stressors from Part A items.

Users & Applications

• Identify symptoms relevant to diagnostic criteria (DSM)
• Track changes in behaviour after intervention

And evaluate children with:

• ADHD-Combined
• ADHD-Inattentive
• Traumatic brain injury
