Each item: 0 (none/never, rarely) to 3 (severe/very often). Total score ranges from 0 to 54. Higher total scores indicate greater illness severity. Change scores=Week 8 score-baseline score.

SecondaryChange From Baseline in the Conners' Comprehensive Behavior Rating Scale (CP-CBRS) Academic Difficulties Total Score and the Language and Math Subscales at Week 8Baseline, 8 weeks
The CP-CBRS academic difficulties total/language/math subscale score is a measure of academic performance. Each subscale item score ranges from 0 (never, seldom) to 3 (very often, very frequently). Total score is expressed as T-score based on gender/age norms. Academic difficulties T-score range: 0-100. Higher T-scores denote greater academic difficulties. Change scores=Week 8 score-baseline score. Least Squares Mean Change is from a restricted maximum likelihood-based, mixed model repeated measure (MMRM) analysis adjusted for fixed class effects of treatment, pooled investigative site, strata (prior stimulant use status), visit, and treatment\*visit interaction, and continuous, fixed effects of baseline total score and baseline score\*visit interaction.
