Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in Total Attention Deficit Hyperactivity Disorder Rating Scale-fourth Edition (ADHD-RS-IV) Score at 7 Weeks [Baseline and 7 weeks]

    Change in the Attention Deficit Hyperactivity Disorder Rating Scale-fourth edition (ADHD-RS-IV) total score from baseline. The ADHD-RS-IV consists of 18 items scored on a 4-point scale ranging from 0 (no symptoms) to 3 (severe symptoms) with total score ranging from 0 to 54.

Secondary Outcome Measures

  1. Weekly Change From Baseline in Total ADHD-RS-IV Score [Baseline and 1, 2, 3, 4, 5, 6, and 7 weeks]

    Change in the Attention Deficit Hyperactivity Disorder Rating Scale-fourth edition (ADHD-RS-IV) total score from baseline. The ADHD-RS-IV consists of 18 items scored on a 4-point scale ranging from 0 (no symptoms) to 3 (severe symptoms) with total score ranging from 0 to 54.

  2. Number of Participants With Improvement on Clinical Global Impression-Improvement (CGI-I) [7 weeks]

    Clinical Global Impression-Improvement (CGI-I) consists of a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 or 2 on the scale.

  3. Number of Participants With Improvement onParent Global Assessment (PGA) [7 weeks]

    Parent Global Assessment (PGA) consists of a 7-point scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved) or 2 (much improved) on the scale.

  4. Change From Baseline in Expression and Emotional Scale for Children (EESC) Scores at 7 Weeks [Baseline and 7 weeks]

    Expression and Emotional Scale for Children (EESC) consists of 29 items rated on a scale from 1 (not true at all) to 5 (very much true). Lower scores reflect better emotional outcomes.

  5. Changes From Baseline in Behavior Rating Inventory of Executive Function (BRIEF) Scores at 7 Weeks [Baseline and 7 weeks]

    Behavior Rating Inventory of Executive Function (BRIEF) is an 86-item questionnaire composed of three scales (Global Executive Composite, Behavioral Recognition Index, and Metacognition Index). Items are rated 1 (never), 2 (sometimes), and 3 (often). Lower scores reflect better functioning.
