Trial Outcomes & Findings for Gene-environment Interactions and Brain Functional Connectivity in Attention Deficit Hyperactivity Disorder (NCT NCT01912352)

NCT ID: NCT01912352

Last Updated: 2014-12-04

Results Overview

Attendtion-deficit hyperactivity disorder (ADHD) Rating Scale-IV is the sum of 18 questions, ranging from 0 (no symptoms) to 54 (worst possible symptoms). Change from baseline ADHD Rating Scale-IV scores at 8 weeks was calculated as baseline minus 8 weeks.

SECONDARY outcome

Timeframe: baseline and 8 weeks

Clinical Global Impression-Improvement (CGI-I) scale is a one-item measure evaluating the change from the initiation of treatment on a seven-point scale: "Compared to the patient's condition at baseline \[prior to medication initiation\], this patient's condition is: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment. Clinical Global Impression-Improvement was measured at 8 weeks.
