Not Applicable

Completed

• Conditions: Decision Analysis; Behavior, Adaptive
• Interventions: Behavioral: presentation order; Behavioral: alternative presentation order

• Registration Number: NCT03498677
• Lead Sponsor: ThinkWell

Brief Summary

This study nested as a randomized controlled trial within an online Delphi and will assess the impact of using different question section groupings to provide aggregate feedback to participants in an online Delphi study.

Detailed Description

A similar assessment has been done during the development of a core outcome for critical care trials set with a nested study examining the impact of question order on prioritization of outcomes. Research reports different stakeholders groups may differ in how they value or prioritize research questions and outcomes and it is recommended that each group should be adequately represented.

The Protocol Lab for Online Trials-Delphi (PLOT-D) study will use an online Delphi combined with participatory action research to inform the development of a multi-use protocol template for writing protocols for self-recruited online trials of interventional self-management. The Protocol lab will use the Delphi findings, along with earlier research to redesign a series of protocols for online randomized trials with the aim of providing support for citizens to work alongside researchers to build participatory health trials online.
