摘要：The Delphi survey technique is an iterative mail or electronic (e-mail or web-based) survey method used to
obtain agreement or consensus among a group of experts in a specific field on a particular issue through a
well-designed and systematic multiple sequential rounds of survey administrations. Each of the multiple
rounds of the Delphi survey administration is augmented with continuous summary feedback of aggregated
responses from the same group of experts. Statistical methods to analyze data from the Delphi surveys to
make decisions for terminating subsequent Delphi data collection are needed to ensure that (a) stability of the
responses of the panel of experts is reached; and (b) termination of the rounds of the Delphi survey
administration is based on sound statistical results. The present study presents an overview of the parametric
and nonparametric statistical methods that can be used to analyze the structured Delphi survey data to make
decisions about terminating the sequential Delphi survey data collection.
