- Change From Baseline in ADHD Impact Module - Adults (AIM-A) Subscale Score at Week 3 [Baseline, Week 3]
AIM-A: 66 item questionnaire completed by the participant to assess the impact of ADHD on the participant's quality of life. It is comprised of 4 global quality of life (QoL) items (current quality of life item [CQoLI], range:1 to 10; global limitation item [GLI]: range:1 to 4, on the right track item [RTI], range:1 to 3, more good days [GD] than bad days [BD], range:1 to 5, higher scores indicate a better QoL for all the 4 QoL items) and 6 multi-item subscales (living with ADHD, general well-being, performance and daily functioning [PDF], relationships and communication [R/C], Impact of symptoms-bother/concern [IS-B/C] scale, and impact of symptoms-interference [IS-I] scale). Participants responded to each item of multi-item subscale using a likert scale ranging from 1 (strongly agree) to 5 (strongly disagree). Multi-item subscale scores were calculated as an average of scores for the contributing items and transformed into 0 to 100 score where higher scores indicate a better QoL.
- Change From Baseline in Adult ADHD Quality of Life Scale (AAQOL) Subscale Score at Week 3 [Baseline, Week 3]
AAQoL is a 29-item questionnaire consisting of 4 subscales: life productivity (11 items), psychological health ([PH] 6 items), life outlook (7 items) and relationships (5 items). Participants rated each item on a scale ranging from 1 (not at all/never) to 5 (extremely/very often). The scores of each item were then transformed to a 0 to 100 point scale, higher scores indicating better quality of life. The score for each subscale was calculated as the sum of the corresponding item scores. Total score ranges were: life productivity (0 to 1100), psychological health (0 to 600), life outlook (0 to 700) and relationships (0 to 500), where higher subscale score indicates better quality of life for each subscale.
- Change From Baseline in Sheehan Disability Scale (SDS) Subscale Scores at Week 3 [Baseline, Week 3]
SDS was a participant-rated questionnaire assessing the effect of the participant's symptoms on the 3 domains/subscales: work/school, social life/leisure activities, and family/home management. Each domain was rated on visual analog scale ranges from 0 to 10 where 0=not at all impaired and 10=extremely impaired, and total SDS score was calculated as a sum of all the domains with a score range of 0=not at all impaired to 30=extremely impaired. Disability scores were reported for each of the domains/subscales. Higher scores reflect greater impairment.
Other Outcome Measures
- Change From Baseline in Medical Outcome Study - Sleep Scale (MOS-SS) Subscale Scores at Week 1, 2 and 3 [Baseline, Week 1, 2, 3]

Title | Change From Baseline in ADHD Impact Module - Adults (AIM-A) Subscale Score at Week 3 |
---|---|
Description | AIM-A: 66 item questionnaire completed by the participant to assess the impact of ADHD on the participant's quality of life. It is comprised of 4 global quality of life (QoL) items (current quality of life item [CQoLI], range:1 to 10; global limitation item [GLI]: range:1 to 4, on the right track item [RTI], range:1 to 3, more good days [GD] than bad days [BD], range:1 to 5, higher scores indicate a better QoL for all the 4 QoL items) and 6 multi-item subscales (living with ADHD, general well-being, performance and daily functioning [PDF], relationships and communication [R/C], Impact of symptoms-bother/concern [IS-B/C] scale, and impact of symptoms-interference [IS-I] scale). Participants responded to each item of multi-item subscale using a likert scale ranging from 1 (strongly agree) to 5 (strongly disagree). Multi-item subscale scores were calculated as an average of scores for the contributing items and transformed into 0 to 100 score where higher scores indicate a better QoL. |

Title | Change From Baseline in Adult ADHD Quality of Life Scale (AAQOL) Subscale Score at Week 3 |
---|---|
Description | AAQoL is a 29-item questionnaire consisting of 4 subscales: life productivity (11 items), psychological health ([PH] 6 items), life outlook (7 items) and relationships (5 items). Participants rated each item on a scale ranging from 1 (not at all/never) to 5 (extremely/very often). The scores of each item were then transformed to a 0 to 100 point scale, higher scores indicating better quality of life. The score for each subscale was calculated as the sum of the corresponding item scores. Total score ranges were: life productivity (0 to 1100), psychological health (0 to 600), life outlook (0 to 700) and relationships (0 to 500), where higher subscale score indicates better quality of life for each subscale. |

Title | Change From Baseline in Sheehan Disability Scale (SDS) Subscale Scores at Week 3 |
---|---|
Description | SDS was a participant-rated questionnaire assessing the effect of the participant's symptoms on the 3 domains/subscales: work/school, social life/leisure activities, and family/home management. Each domain was rated on visual analog scale ranges from 0 to 10 where 0=not at all impaired and 10=extremely impaired, and total SDS score was calculated as a sum of all the domains with a score range of 0=not at all impaired to 30=extremely impaired. Disability scores were reported for each of the domains/subscales. Higher scores reflect greater impairment. |

Title | Change From Baseline in Medical Outcome Study - Sleep Scale (MOS-SS) Subscale Scores at Week 1, 2 and 3 |
---|---|
Description | Participant-rated 12-item questionnaire to assess sleep quality and quantity. The items contribute to each scale and are averaged to create the 7 subscale scores: sleep disturbance, snoring, awaken short of breath (ASoB) or with a headache, somnolence, sleep adequacy, sleep quantity (range 0 to 24) and optimal sleep, and overall sleep problem index (SPI) I (range 0 to 600) and II. Except for sleep quantity and sleep problem index I, scores are transformed (actual raw score minus lowest possible score divided by possible raw score range* 100); total score range: 0 to 100; higher score = greater intensity of attribute. Except for sleep quantity, higher scores=greater impairment. Scales with at least one item answered was used to generate a scale score. |
