Advantages and Limitations of the e-Delphi Technique: Implications for Health Education Researchers

In the last 30 years, the application of the Delphi technique has been increasing. With the recent availability and established popularity of Internet-based research tools, the Internet has been identified as a means for mitigating Delphi limitations, maximizing its advantages, and expanding the breadth of its application. The discourse on the application of "e-Delphi" has been speculative in nature, however, with pragmatic analysis of Internet-based Delphi administration being limited in scope. Concomitantly, methodological guidance for conducting the e-Delphi in health education is limited, with best-practice implementation strategies yet to emerge. This paper advances the understanding of the e-Delphi technique, contributes to the evolution of this Internet-based research methodology, and provides guidance for the e-Delphi researcher in health education. Further, it offers a contribution to the discourse about Internet-based inquiry generally, and on using the e-Delphi technique in health education specifically. The authors illustrate that e-Delphi has a range of benefits that are effective and efficient in assuaging traditional Delphi limitations; nevertheless, a set of methodological issues remain unaddressed and make apparent the need for future research investments to better understand and alleviate challenges presented for e-Delphi research in health education.
