Trial Outcomes & Findings for Decisional Capacity and Informed Consent in Fragile X Syndrome (NCT NCT02465931)
NCT ID: NCT02465931
Last Updated: 2019-03-07
Results Overview
MacArthur Decisional Capacity - understanding score, range 0 (no understanding) to 26 (perfect understanding) A summary score was calculated, ranging from 0-26. Scores were then translated into a percentage based on the number of questions answered. A score of 100% indicates that the participant answered each understanding question correctly on the first attempt.
