Developing Consensus Using the Delphi Method

Area of Science:

• Consensus Methodology
• Decision Science
• Research Methods

Background:

• The Delphi method is a structured communication technique.
• It facilitates expert consensus on specific topics like treatment algorithms or curriculum development.

Purpose of the Study:

• To introduce novice researchers to the Delphi method.
• To outline the classic and modified Delphi processes.
• To detail elements that enhance the rigor of Delphi studies.

Main Methods:

• Anonymously surveying a panel of experts iteratively.
• Ranking items and suggesting modifications across survey rounds.
• Amending survey items based on quantitative and qualitative analysis of prior results.
• Utilizing modified Delphi approaches, potentially including in-person elements or literature-based initial surveys.

Main Results:

• Iterative feedback and analysis guide the consensus-building process.
• Qualitative analysis of comments provides deeper insights.
• Consensus is achieved when a predetermined cutoff is met.

Conclusions:

• Thoughtful design, including clear panel selection, evidence-based items, and defined consensus criteria, enhances Delphi study rigor.
• The Delphi method can yield trustworthy results with broad acceptance.
• Qualitative insights can highlight areas of non-consensus.
