Novel approach to parental permission and child assent for research: improving comprehension.

TLDR: Multimedia approaches to the research P/A process may improveOverall understanding of research participation for children and parents and improved understanding of study-specific research components (rather than research rights) may improve overall comprehension.

Abstract: OBJECTIVE: The aim of this research was to test a multimedia permission/assent (P/A) process. The overall hypothesis was that children and their parents exposed to a multimedia P/A process would have better comprehension compared with those exposed to a text-based process. METHODS: Traditional and multimedia P/A processes were created by using an innovative learning-objective approach. A total of 194 parent-child dyads (children aged 11―14 years) were enrolled: 24 dyads in a prestudy testing P/A components for preference and effect on comprehension and 170 dyads in a randomized trial of a multimedia or paper P/A process for a hypothetical study. Participants were predominantly white and were from a metropolitan area served by a tertiary care pediatric hospital and outpatient facility. Comprehension of 8 essential elements of the P/A process was assessed. RESULTS: The majority of prestudy subjects preferred the video version of the dual-energy radiograph absorptiometry description over theanimated and paper versions combined (41 of 48 [85%]; P < .0001), and there were similar results for the abdominal ultrasound description (38 of 47 [81%]; P< .0001). Children exposed to the novel process showed significantly better overall comprehension compared with the paper P/A process (P = .0009), and there were highly significant differences in understanding of study procedures (P = .0002) and risks (P < .0001). The parental multimedia group had significantly better overall comprehension (P = .03). CONCLUSIONS: Multimedia approaches to the research P/A process may improve overall understanding of research participation for children and parents. Improved understanding of study-specific research components (rather than research rights) may improve overall comprehension.
