Learner Objectives

This session will help participants…

  1. understand the normative sample and scores for a revised measure of ADHD.
  2. learn about the evidence for reliability and validity of the measure.
  3. learn about the fairness of the measure and its lack of bias against historically marginalized groups.


The Conners 4th Edition (Conners 4) is a revision of a measure for youth ADHD symptoms, associated features, and functional impairments. Normative samples were collected to reflect the general population of U.S. and Canada, and normative scores were calculated based on age and gender. Its psychometric properties were explored; strong evidence is provided for reliability (internal consistency and test–retest reliability), validity (internal structure and differences among clinical groups), and fairness (minimal differences among demographic groups).
