Comparison of Atomoxetine and Placebo in Children With Attention-Deficit/Hyperactivity Disorder (ADHD) and/or Reading Disorder (RD)

SSRT measures response execution (go trials) and response inhibition (stop trials). Go trials consist of stimulus (airplane). Child to press response button corresponding to direction airplane is pointing. Stop trials consist of go trial and audible stop signal. Initial delay between go trial and stop signal = 250 msec. If child succeeded in inhibiting response, delay on next stop trial increased by 50 msec, otherwise, delay decreased by 50 msec. SSRT = subtract mean delay from mean go signal reaction time. Lower scores mean better ability to suppress response when presented with stop signal.

Measure of reaction time to identify whether a word displayed on a computer is a real or correct word versus a pseudo word. During the performance of the lexical decision task that was presented on a computer, the reaction times and accuracy of responses were measured. Data presented are the mean reaction times over the 4 weeks of each therapy for identifying correct words correctly.

Measures the visuo-spatial working memory span, and corresponds to the longest sequence of blocks that has been reproduced correctly at least once. Scores can range from 3 to 8, with the higher score indicating better function.

Measures the 18 symptoms contained in the DSM-IV diagnosis of Attention-Deficit/Hyperactivity Disorder. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total score is the sum of the scores on the 18 items and range from 0 to 54.

Measures the degree of inattention symptoms based on answers to 9 items. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often), for a total Inattention Subscale score range of 0 to 27.

Measures the degree of hyperactivity-impulsivity symptoms, based on answers to 9 items. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often) for a total Hyperactivity-Impulsivity Subscale score of 0 to 27.

Measures the 18 symptoms contained in the DSM-IV diagnosis of Attention-Deficit/Hyperactivity Disorder. Individual item scores range from 0 (none/never or rarely) to 3 (severe/very often). Total score is computed as the sum of the scores on each of the 18 items. Total score is the sum of the scores on the 18 items and range from 0 to 54. Total T-score = (Total Score - 50)/10. Total T-score ranges from -5 (low severity) to 0.4 (high severity).

Measures total improvement (or worsening) of a patient's ADHD symptoms from the beginning of treatment (1=very much improved, 7=very much worsened).

Measures severity of the patient's overall severity of ADHD symptoms (1=normal, not at all ill; 7=among the most extremely ill patients).

Measure of reaction time in determining whether the stimulus sounds like a real word ('yes' response) or not ('no' response) using pseudohomophones and pseudo words. Data presented here are for reaction time to identifying psuedohomophones correctly.
