Trial Outcomes & Findings for The Effects of Vyvanse(TM) on Brain Hemodynamics and Reading (NCT NCT00733356)

NCT ID: NCT00733356

Last Updated: 2018-02-14

Results Overview

The GORT-4 evaluates oral reading rate, accuracy and comprehension. Both Forms A and B were used.Half of the subjects randomly were tested on From A at baseline and the other half were tested with Form B. The GORT-4 is a standardized measure/test. Scores provided are standard scores, which range from 1 to 20, with a Mean of 10 and Standard Deviation of 3. A higher score means better reading performance. There was no total score used or calculated in this study.

Participant Flow

Subjects were recruited through flyers and other advertising and were seen in a researach clinic setting. Subjects were recruited from july 2008 until May 2009. A primary diagnosis of ADHD was confirmed. All subjects were also given a K-BIT intelligence test and had to achieve a score of at least 80 to be enrolled.

All subjects who met study criteria for ADHD and intellectual ability who were also healthy and had no other co-morbid diagnosis except possible ODD were enrolled in the study. Any subjects taking stimulant medication before the trial did a 2-day washout before baseline. 42 subjects consented, 5 didn't meet criteria, 9 withdrew consent.
