Attention Deficit Hyperactivity Disorder
Conditions
Brief summary
The purpose of the study is to investigate the relationship of changes in measures of academic performance and problem behaviors, to changes in core Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in Asian children treated with atomoxetine.
Interventions
atomoxetine 0.5 mg/kg/day once a day (QD), by mouth (PO) starting dose titrated over 1 week to target dose 1.2 mg/kg/day QD, PO for 23 weeks.

ADHD-RS measures 18 symptoms associated with diagnosis of ADHD. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total scores range from 0 to 54. SGA: Grades (0 to 100) in classes of Language, Math, and Science were obtained and average taken to get SGA Total Score between 0 and 100; higher scores indicating better grades/apptitude. Any ordinal grades were imputed to numerical grades based on communication with relevant schools. |

Subscale assessed: ADHD Index. ADHD Index is the sum of items 1, 5, 7, 10, 13, 15, 17, 19, 21, 23, 25, and 27. Subscale total scores range from 0 to 36.

Outcome results
Correlation Between Change From Baseline and 24 Week Endpoint in Attention-Deficit/Hyperactivity Disorder Rating Scale-IV-Parent:Investigator-Administered and Scored (ADHDRS-IV-Parent:Inv) Total Score and School Grade Average (SGA)
Correlation was calculated between change from baseline and endpoint in ADHD-RS Total Score and change in SGA total score. ADHD-RS measures 18 symptoms associated with diagnosis of ADHD. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total scores range from 0 to 54. SGA: Grades (0 to 100) in classes of Language, Math, and Science were obtained and average taken to get SGA Total Score between 0 and 100; higher scores indicating better grades/apptitude. Any ordinal grades were imputed to numerical grades based on communication with relevant schools.
Time frame: Baseline, 24 weeks
Population: All patients with baseline and at least one non-missing post-baseline score for each of the variables, regardless of them having or not having received any ordinal grades (for the SGA).
