    Outcomes

    Primary Outcome Measures

    Change From Baseline in Attention Deficit Hyperactivity Disorder Rating Scale (ADHD-RS-IV) Score at Up to 5 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

    Change From Baseline in Conner's Parent Rating Scale-revised Short Version (CPRS-R) Score at Up to 5 Weeks
    The Conner's Parent rating Scale-revised short version (CPRS-R) consists of 27 questions graded on a scale from 0 (not true at all) reflecting no symptoms to 3 (very much true) reflecting severe symptoms with a total score ranging from 0 to 81. Higher scores are indicative of increased ADHD. This scale allows parents to respond on the basis of the child's behavior and help assess ADHD and evaluate problem behavior.
    Change From Baseline in Conner's Teacher Rating Scale-revised Short Version (CTRS-R) Score at Up to 5 Weeks
    The Conner's Teacher Rating Scale-revised short version (CTRS-R) consists of 28 questions graded on a scale from 0 (not true at all) reflecting no symptoms to 3 (very much true) reflecting severe symptoms with a total score ranging from 0 to 84. Higher scores are indicative of increased ADHD. This scale allows teachers to respond on the basis of the child's behavior and help assess ADHD and evaluate problem behavior.
    Number of Participants With Improvement in Clinical Global Impression-Improvement (CGI-I)
    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 (very much improved) or 2 (much improved) on the scale.
    Number of Participants With Improvement in Parent Global Assessment (PGA)
    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.
    Change From Baseline in Child Health Questionnaire-Parent Form (CHQ-PF50) Score at 5 Weeks
    The Child Health Questionnaire-Parent Form (CHQ-PF50) was developed to measure the physical and psychosocial well-being of children aged 5 years of age and older. Total score ranges from 0-100. Increases in scores represent improved well-being in subjects as assessed by their parents.
