CAARS-Inv:SV is a scale that assesses symptom severity over past week. Total ADHD symptom score consisted of 18 items (sum of inattention [9 items, range: 0-27] and hyperactivity-impulsivity [9 items, range: 0-27] subscales) using a 4-point scale (0=not at all/never to 3=very much/very frequently) for total score range of 0 to 54. Higher scores indicate greater impairment.

All randomized participants with a baseline and at least 1 post-baseline CAARS-Inv:SV result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

Participant-reported outcome measure used to examine disease-specific functional impairments and QoL for adults with ADHD. The domains include work functioning, family relationships, social functioning, activities of daily living (that is, driving, managing finances), and psychological adaptation (that is, life satisfaction and self-esteem). Individual items scored on a 5-point scale from 1 (not at all/never) to 5 (extremely/very often). Range of scores for this subscale is 0 to 100. Consistent with the majority of existing QoL measures, higher scores on AAQoL-29 indicate better functioning.

All randomized participants with a baseline and at least 1 post-baseline AAQoL result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

The EQ-5D is a generic, multidimensional, health-related, quality-of-life instrument. Overall health state score is self-reported using a visual analogue scale marked on a scale of 0 to 100 with 0 representing worst imaginable health state and 100 representing best imaginable health state.

All randomized participants with a baseline and at least 1 post-baseline EQ-5D result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

CAARS-Inv:SV assesses symptom severity over past week. Total ADHD symptom score comprises 18 items (sum of inattention [9 items, range: 0-27] and hyperactivity-impulsivity [9 items, range: 0-27] subscales) using a 4-point scale (0=not at all/never to 3=very much/very frequently). Total score range: 0 to 54. Higher scores=greater impairment. Least Squares Mean Value based on mixed model repeated measures analysis with term for baseline, country, visit, treatment, and treatment*visit. Baseline included as a covariate; thus, treatment difference in observed value is same as change from baseline.

All randomized participants with a baseline and at least 1 post-baseline CAARS-Inv:SV result were included in the analysis.

A 75-item standardized self-reported measure comprised of 3 subscales. Each item is rated on a 3-point Likert scale (1=behavior never observed to 3=behavior often observed). Behavioral regulation subscale measures one's control over behavior (30-90 total score). Metacognition subscale assesses systematic problem-solving ability while sustaining these task-completion efforts in active working memory (40-120 total score). Global executive composite (GEC) subscale rates participant's GEC in everyday environment (75- 225 total score). Higher subscale ratings=greater perceived impairment.

All randomized participants with a baseline and at least 1 post-baseline BRIEF-A result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

Third-party observer of participant completes 75-item scale. Comprised of 3 subscales. Each item rated on 3-point Likert scale (1=behavior never observed to 3=behavior often observed). Behavioral regulation subscale measures one's control over behavior (30-90 total score). Metacognition subscale assesses systematic problem-solving ability while sustaining these task-completion efforts in active working memory (40-120 total score). Global executive composite (GEC) subscale rates participant's GEC in everyday environment (75-225 total score). Higher subscale ratings=greater perceived impairment.

All randomized participants with a baseline and at least 1 post-baseline BRIEF-A result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

The CGI-ADHD-S is a single-item clinician rating of the clinician's assessment of the overall severity of the participant's ADHD symptoms in relation to the clinician's total experience with ADHD participants. Measures severity of the participant's overall severity of ADHD symptoms (1=normal, not at all ill to 7=among the most extremely ill participants).

All randomized participants with a baseline and at least 1 post-baseline CGI-ADHD-S result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

The CGI-ADHD-I is a single-item clinician rating of the clinician's assessment of the participant's improvement in ADHD symptoms in relation to the clinician's total experience with ADHD participants. Measures total improvement (or worsening) of a participant's ADHD symptoms from the beginning of treatment (1=very much improved to 7=very much worsened).

All randomized participants with an endpoint CGI-ADHD-I value within each treatment group, last observation carried forward (LOCF) were included in the analysis.

Clinician-administered rating scale that assesses severity of anxiety and its improvement (or change) during course of treatment (Hamilton 1959; Riskind et al. 1987). Scale consists of 14 items that provide an overall measure of general anxiety, including psychic anxiety and somatic anxiety. Investigator talked to participant about participant's symptoms over previous week before study visit. Each item is rated on a 5-point scale of 0 (absent) to 4 (very severe). Total score=sum of 14 items and ranges from 0 (normal) to 56 (severe). Higher scores indicate a greater degree of symptom severity.

All randomized participants with a baseline and at least 1 post-baseline HAMA-14 result within each treatment group, last observation carried forward (LOCF) were included in the analysis.

The HAMD-17 was used to assess the severity of depression and its improvement during the course of therapy. Each item was evaluated and scored using either a 5-point scale of 0 (not present) to 4 (very severe) or a 3-point scale of 0 (not present) to 2 (marked). Higher scores indicate greater symptom severity. The total score is the sum of the scores from HAMD-17 Items 1 through 17. The total score may range from 0 (not at all depressed) to 52 (severely depressed). Higher scores indicate a greater degree of symptom severity.

All randomized participants with a baseline and at least 1 post-baseline HAMD-17 result within each treatment group, last observation carried forward (LOCF) were included in the analysis.
