Methodology Update: Delphi Studies

Background The Delphi method is a research approach that is beneficial when wanting to solve real-world problems, and expert opinions are needed. Objectives The purpose of this study was to describe the Delphi method as a qualitative research approach and provide a case study example of a study using the Delphi method to demonstrate the advantages and challenges of this methodological approach. Methods A literature search was conducted to understand the Delphi method and examine its use in nursing. Results The literature search revealed what the Delphi method was and how it could be used. To better help explain the method, a case study from the literature is presented. Discussion Using the Delphi method in nursing research is becoming easier. With emerging technology, communication with geographically diverse experts may be easily and affordably achieved. With updated software, results can be interpreted almost immediately, and additional rounds of the Delphi occur in a timely manner, increasing participation and decreasing attrition rates. The Delphi method is a viable option for nurse researchers looking for expert opinion.
