Product Description

Detect executive function issues based on behaviours

Delivered online via Q-global|, 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 5-19. This flexible, sensitive assessment includes parent, teacher and self-ratings with 36 items that are answered as: Seldom/Never; Monthly; Weekly; or Daily.
