Learner Objectives

This session will help participants…

  1. develop a preliminary understanding of a multimethod approach to ADHD assessment.
  2. gain an understanding of direct versus indirect measures and how they are used in ADHD assessment.
  3. explore the convergent and incremental validity of two of the most widely utilized direct and indirect measures in ADHD assessment.


The present study examined the incremental validity of direct measures of attentional capacities over and above indirect assessments using teacher ratings of attention deficit hyperactivity disorder (ADHD) symptoms to predict classification. The Conners Continuous Performance Test 3rd Edition (CPT 3) was used as the direct measure of attention and the Conners ADHD Index (Conners 3AI) was used as the indirect measure.
