NCT ID: NCT00899392

Last Updated: 2013-07-30

Results Overview

Units on a scale (score) as Measured by Consent 20 Instrument. 20 questions administered on a laptop computer and answered in private. Questions 1-5: qualitative questions about recalling procedure, risks, benefits, etc. (correct or incorrectly scored 0 or 2 points), Questions 6-20: yes or no responses, measuring delivery, voluntariness, and understanding. Each scored 0 or 2 points. Measures theoretical attainment of a minimum standard of informed consent. Worse value: Zero Best Value: 40

Participant Flow

Between October 2008 and March 2009, parents of 220 children scheduled for clinically indicated upper endoscopy were prospectively and consecutively contacted. 190 subjects verbally consented to be in the study and 148 subsequently participated. 6 were withdrawn from data secondary to entering disqualifying demographic response (not in data set)

30 subjects did not participate because they did not consent to participate. These were not enrolled in the study.
