Reporting Groups
  Description
OROS Methylphenidate Children participated in a double blind placebo controlled crossover study comparing one week of treatment with the optimal dose of OROS methylphenidate with one week of treatment with placebo. The order of administering OROS-methylphenidate versus placebo was randomized and counterbalanced across participants. At the end of each week the child’s performance on different domains of attention and executive functioning was assessed on the measures described below.

Measure Type Primary
Measure Title Test of Everyday Attention for Children: Map Mission
Measure Description The TEA-Ch is a battery of nine subtests designed to assess multiple attentional capacities in children 6-16y.o. The Map Mission subtest is a measure of selective attention and indicates the number of targets found in one minute. Scores on this subtest can range from 0 to over 70 with higher scores representing improved performance.
Time Frame 2 weeks  
Safety Issue No
