Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Attention Deficit/Hyperactivity Disorder (ADHD) Symptoms Total Score of the Conners Adult ADHD Rating Scale (CAARS)
Time Frame: from baseline to 13 weeks
|
The primary endpoint was the change in the ADHD symptoms total score of the investigator-rated CAARS from baseline to the last assessment in the double-blind treatment period.
CAARS assesses ADHD symptoms and behaviors in adults using a scale ranging from 0 (best) to 54 (worst).
For subjects without a post-baseline efficacy measurement, a change of 0 units was imputed.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change in Clinical Global Impression-Severity (CGI-S) From Baseline to End of Treatment
Time Frame: from baseline to13 weeks
|
The CGI-S rating scale is used to rate the severity of a subject's illness on a 7-point scale ranging from 1 (not ill) to 7 (extremely severe illness).
The change in CGI-S was assessed from baseline to end of treatment (week 13 or or last post-baseline assessment)
|
from baseline to13 weeks
|
|
Clinical Global Impression-Change (CGI-C)
Time Frame: 13 weeks
|
The CGI-C rating scale is used to rate the change in severity of the subject's illness compared to baseline on a 7-point scale ranging from 1 (very much improved) to 7 (very much worse).
|
13 weeks
|
|
Change in Conners Adult ADHD Rating Scale Self Report Short Version (CAARS-S:S) Total Score
Time Frame: from baseline to 13 weeks
|
The CAARS-S:S is a 26-item self-report scale that measures symptoms based on the DSM-IV criteria for ADHD.
Respondents were asked to rate items pertaining to their behavior/problems using the following 4-point scale (from 0 = Not at all, never; to 3 = Very much, very frequently).
The CAARS-S:S total score range is from 0 (best) to 78 (worse).
The change in CAARS-S:S was assessed from baseline to end of treatment (week 13 or or last post-baseline assessment)
