When using the Delphi process, investigators need not only to achieve a desirable response rate in the initial round but they must also concern themselves with maintaining high response rates in the following iterations. Due to the potential scarcity of qualified participants and the relatively small number of subjects used in a Delphi study, the ability to achieve and maintain an ideal response rate can either ensure or jeopardize the validity of a Delphi study. The purpose of this paper is to discuss possible options to achieve and maintain a desirable response rate when engaged in a Delphi research project. These possible options focus on the importance of seeking help from well recognized experts or endorsed individuals, the value in establishing the first contact with each participant, the option of utilizing different forms and formats of questions, the use of incentives to encourage response and finally, strategies for dealing with non-respondents.
