Brief Summary:
To examine the effects of using decision support tools during the online Delphi process.

Condition or disease Intervention/treatment Phase
Behavioral Changes Behavioral: MCDA Behavioral: Delphi Not Applicable

Detailed Description:

The purpose of this exploratory work is to develop improved methods for building a protocol for a participatory randomized controlled trial. An online Delphi will be combined with an embedded trial testing the effectiveness of a decision support tool. This method provides for consensus building and collaborative problem-solving which is informed, and participatory. The online Delphi offers involvement and confidentiality thus sidestepping the complications of power imbalances and undue influence as respondents contribute anonymously.

The embedded trial was considered after the building of a database of existing online trials and conducting a descriptive analysis" Creating a database of Internet-based clinical trials to support a public-led research programme: A descriptive analysis, followed by the completion of a systematic overview of systematic overviews, "Patient and Public Involvement in Clinical Trials Design: An Overview of Systematic Reviews" and followed this with an analysis of "Self-Management Open Online Trials in Health"(In review). The results included a lack of standardization, insufficient guidance for implementation and significant research reporting weaknesses. Decision-making support tools may improve decision quality.

This embedded trial will be implemented in an online Delphi to come to the consensus about what declarations and methods to include when building a participatory online trials protocol.

Primary Outcome Measures :
  1. My Decision Quality (MDQ) [ Time Frame: Up to 20 weeks or study completion ]
    MDQ is a patient reported outcome measure that combines a set of importance weights for multiple criteria (options, effect, importance, chance, trust, support ,control and commitment) with performance ratings for each option on these criteria and calculates the overall score as the expected value of these components.

Other Outcome Measures:
  1. Time to consensus [ Time Frame: Up to 20 weeks or study completion ]
    Aggregated group time to reach consensus
